ISC CSSLP Certified Secure Software Lifecycle Professional Exam Practice Test

This is an example of transference. When the risk is transferred to a third party, usually for a fee, it creates a contractual-relationship for the third party to manage the risk on behalf of the performing organization. Risk response planning is a method of developing options to decrease the amount of threats and make the most of opportunities. The risk response should be aligned with the consequence of the risk and cost-effectiveness. This planning documents the processes for managing risk events. It addresses the owners and their responsibilities, risk identification, results from qualification and quantification processes, budgets and times for responses, and contingency plans. The various risk response planning techniques are as follows: Risk acceptance: It indicates that the project team has decided not to change the project management plan to deal with a risk, or is unable to identify any other suitable response strategy. Risk avoidance: It is a technique for a threat, which creates changes to the project management plan that are meant to either eliminate the risk or to protect the project objectives from this impact. Risk mitigation: It is a list of specific actions being taken to deal with specific risks associated with the threats and seeks to reduce the probability of occurrence or impact of risk below an acceptable threshold. Risk transference: It is used to shift the impact of a threat to a third party, together with the ownership of the response.

Trusted Computer System Evaluation Criteria (TCSEC) is a United States Government Department of Defense (DoD) standard that sets basic requirements for assessing the effectiveness of computer security controls built into a computer system. TCSEC was used to evaluate, classify, and select computer systems being considered for the processing, storage, and retrieval of sensitive or classified information. It was replaced with the development of the Common Criteria international standard originally published in 2005. The TCSEC, frequently referred to as the Orange Book, is the centerpiece of the DoD Rainbow Series publications. Answer: D is incorrect. System Security Authorization Agreement (SSAA) is an information security document used in the United States Department of Defense (DoD) to describe and accredit networks and systems. The SSAA is part of the Department of Defense Information Technology Security Certification and Accreditation Process, or DITSCAP (superseded by DIACAP). The DoD instruction (issues in December 1997, that describes DITSCAP and provides an outline for the SSAA document is DODI 5200.40. The DITSCAP application manual (DoD 8510.1- M), published in July 2000, provides additional details. Answer: A is incorrect. FITSAF stands for Federal Information Technology Security Assessment Framework. It is a methodology for assessing the security of information systems. It provides an approach for federal agencies. It determines how federal agencies are meeting existing policy and establish goals. The main advantage of FITSAF is that it addresses the requirements of Office of Management and Budget (OMB). It also addresses the guidelines provided by the National Institute of Standards and Technology (NIsT). Answer: B is incorrect. The Federal Information Processing Standards (FIPS) are publicly announced standards developed by the United States federal government for use by all non-military government agencies and by government contractors. Many FIPS standards are modified versions of standards used in the wider community (ANSI, IEEE, ISO, etc.). Some FIPS standards were originally developed by the U.S. government. For instance, standards for encoding data (e.g., country codes), but more significantly some encryption standards, such as the Data Encryption Standard (FIPS 46-3) and the Advanced Encryption Standard (FIPS 197). In 1994, NOAA (Noaa) began broadcasting coded signals called FIPS (Federal Information Processing System) codes along with their standard weather broadcasts from local stations. These codes identify the type of emergency and the specific geographic area (such as a county) affected by the emergency.

The 'Do' cycle component performs the following activities: It operates the selected controls. It detects and responds to incidents properly. It performs security awareness training. It manages resources that are required to achieve a goal. Answer: B is incorrect. This activity is performed by the 'Plan' cycle component of PDCA.

The Phase 1 of the DITSCAP C&A process is known as Definition Phase. The goal of this phase is to define the C&A level of effort, identify the main C&A roles and responsibilities, and create an agreement on the method for implementing the security requirements. Answer: C is incorrect. The Phase 2 of the DITSCAP C&A process is known as Verification. Answer: D is incorrect. The Phase 3 of the DITSCAP C&A process is known as Validation. Answer: B is incorrect. The Phase 4 of the DITSCAP C&A process is known as Post Accreditation.

The main steps of performing risk analysis are as follows: Estimate the potential losses to the assets by determining their value. Evaluate the potential threats to the assets. Establish the threats probability and regularity. Answer: A is incorrect. Valuations of the critical assets in hard costs is one of the final steps taken after performing the risk analysis.

Regression testing can be performed any time when a program needs to be modified either to add a feature or to fix an error. It is a process of repeating Unit testing and Integration testing whenever existing tests need to be performed again along with the new tests. Regression testing is performed to ensure that no existing errors reappear, and no new errors are introduced. Answer: D is incorrect. The acceptance testing is performed on the application before its implementation into the production environment. It is done either by a client or an application specialist to ensure that the software meets the requirement for which it was made. Answer: A is incorrect. Integration testing is a logical extension of unit testing. It is performed to identify the problems that occur when two or more units are combined into a component. During integration testing, a developer combines two units that have already been tested into a component, and tests the interface between the two units. Although integration testing can be performed in various ways, the following three approaches are generally used: The top-down approach The bottom-up approach The umbrella approach Answer: C is incorrect. Unit testing is a type of testing in which each independent unit of an application is tested separately. During unit testing, a developer takes the smallest unit of an application, isolates it from the rest of the application code, and tests it to determine whether it works as expected. Unit testing is performed before integrating these independent units into modules. The most common approach to unit testing requires drivers and stubs to be written. Drivers and stubs are programs. A driver simulates a calling unit, and a stub simulates a called unit.

The business continuity plan development refers to the utilization of the information collected in the Business Impact Analysis (BIA) for the creation of the recovery strategy plan to support the critical business functions. The information gathered from the BIA is mapped out to make a strategy for creating a continuity plan. The business continuity plan development process includes the areas of plan implementation, plan testing, and ongoing plan maintenance. This phase also consists of defining and documenting the continuity strategy. Answer: C is incorrect. The scope and plan initiation process in BCP symbolizes the beginning of the BCP process. It emphasizes on creating the scope and the additional elements required to define the parameters of the plan. The scope and plan initiation phase embodies a check of the company's operations and support services. The scope activities include creating a detailed account of the work required, listing the resources to be used, and defining the management practices to be employed. Answer: B is incorrect. The business impact assessment is a method used to facilitate business units to understand the impact of a disruptive event. This phase includes the execution of a vulnerability assessment. This process makes out the mission-critical areas and business processes that are important for the survival of business. It is similar to the risk assessment process. The function of a business impact assessment process is to create a document, which is used to help and understand what impact a disruptive event would have on the business. Answer: D is incorrect. The plan approval and implementation process involves creating enterprise-wide awareness of the plan, getting the final senior management signoff, and implementing a maintenance procedure for updating the plan as required.

When an attacker successfully inserts an intermediary software or program between two communicating hosts, it is known as man-in-the-middle attack.

Integrity ensures that no intentional or unintentional unauthorized modification is made to data. Answer: D is incorrect. Confidentiality refers to the protection of data against unauthorized access. Administrators can provide confidentiality by encrypting data. Answer: A is incorrect. Non-repudiation is a mechanism to prove that the sender really sent this message. Answer: C is incorrect. Authentication is the process of verifying the identity of a person or network host.

The definition phase of the DITSCAP/NIACAP model takes place at the beginning of the project, or at the initial C&A effort of a legacy system. C&A consists of four phases in a DITSCAP assessment. These phases are the same as NIACAP phases. The order of these phases is as follows: 1.Definition: The definition phase is focused on understanding the IS business case, the mission, environment, and architecture. This phase determines the security requirements and level of effort necessary to achieve Certification & Accreditation (C&A). 2.Verification: The second phase confirms the evolving or modified system's compliance with the information. The verification phase ensures that the fully integrated system will be ready for certification testing. 3.Validation: The third phase confirms abidance of the fully integrated system with the security policy. This phase follows the requirements slated in the SSAA. The objective of the validation phase is to show the required evidence to support the DAA in accreditation process. 4.Post Accreditation: The Post Accreditation is the final phase of DITSCAP assessment and it starts after the system has been certified and accredited for operations. This phase ensures secure system management, operation, and maintenance to save an acceptable level of residual risk.

The authorizing official is the senior manager responsible for approving the working of the information system. He is responsible for the risks of operating the information system within a known environment through the security accreditation phase. In many organizations, the authorizing official is also referred as approving/accrediting authority (DAA) or the Principal Approving Authority (PAA). Answer: C is incorrect. The system owner has the responsibility of informing the key officials within the organization of the requirements for a security C&A of the information system. He makes the resources available, and provides the relevant documents to support the process. Answer: A is incorrect. An Information System Security Officer (ISSO) plays the role of a supporter. The responsibilities of an Information System Security Officer (ISSO) are as follows: Manages the security of the information system that is slated for Certification & Accreditation (C&A). Insures the information systems configuration with the agency's information security policy. Supports the information system owner/information owner for the completion of security-related responsibilities. Takes part in the formal configuration management process. Prepares Certification & Accreditation (C&A) packages. Answer: D is incorrect. The CISO has the responsibility of carrying out the CIO's FISMA responsibilities. He manages the information security program functions.

A distributed denial of service (DDoS) attack targets a Web server with multiple compromised computers that are simultaneously sending hundreds of FIN packets with spoofed IP source IP addresses. DDoS attack occurs when multiple compromised systems flood the bandwidth or resources of a targeted system, usually one or more Web servers. These systems are compromised by attackers using a variety of methods. It is an attempt to make a computer resource unavailable to its intended users. This type of attack can cause the following to occur: Saturate network resources. Disrupt connections between two computers, thereby preventing communications between services. Disrupt services on a specific computer. Answer: D is incorrect. Dictionary attack is a type of password guessing attack. This type of attack uses a dictionary of common words to find out the password of a user. It can also use common words in either upper or lower case to find a password. There are many programs available on the Internet to automate and execute dictionary attacks. Answer: C is incorrect. In an insertion attack, an IDS accepts a packet and assumes that the host computer will also accept it. But in reality, when a host system rejects the packet, the IDS accepts the attacking string that will exploit vulnerabilities in the IDS. Such attacks can badly infect IDS signatures and IDS signature analysis. Answer: B is incorrect. An evasion attack is one in which an IDS rejects a malicious packet but the host computer accepts it. Since an IDS has rejected it, it does not check the contents of the packet. Hence, using this technique, an attacker can exploit the host computer. In many cases, it is quite simple for an attacker to send such data packets that can easily perform evasion attacks on an IDSs.

The SCM process defines the need to trace changes, and the ability to verify that the final delivered software has all of the planned enhancements that are supposed to be included in the release. It identifies four procedures that must be defined for each software project to ensure that a sound SCM process is implemented. They are as follows: 1.Configuration identification: Configuration identification is the process of identifying the attributes that define every aspect of a configuration item. A configuration item is a product (hardware and/or software) that has an end-user purpose. These attributes are recorded in configuration documentation and baselined. 2.Configuration change control: Configuration change control is a set of processes and approval stages required to change a configuration item's attributes and to re-baseline them. 3.Configuration status accounting: Configuration status accounting is the ability to record and report on the configuration baselines associated with each configuration item at any moment of time. 4.Configuration audits: Configuration audits are broken into functional and physical configuration audits. They occur either at delivery or at the moment of effecting the change. A functional configuration audit ensures that functional and performance attributes of a configuration item are achieved, while a physical configuration audit ensures that a configuration item is installed in accordance with the requirements of its detailed design documentation.

Regression testing focuses on finding defects after a major code change has occurred. Specifically, it seeks to uncover software regressions, or old bugs that have come back. Such regressions occur whenever software functionality that was previously working correctly stops working as intended. Typically, regressions occur as an unintended consequence of program changes, when the newly developed part of the software collides with the previously existing code. Regression testing tests the system efficiency by systematically selecting the suitable and minimum set of tests that are required to effectively cover the affected changes. Answer: A is incorrect. Unit testing is a type of testing in which each independent unit of an application is tested separately. During unit testing, a developer takes the smallest unit of an application, isolates it from the rest of the application code, and tests it to determine whether it works as expected. Unit testing is performed before integrating these independent units into modules. The most common approach to unit testing requires drivers and stubs to be written. Drivers and stubs are programs. A driver simulates a calling unit, and a stub simulates a called unit. Answer: C is incorrect. Acceptance testing is performed on the application before its implementation into the production environment. It is done either by a client or an application specialist to ensure that the software meets the requirement for which it was made. Answer: B is incorrect. Integration testing is a software testing that seeks to verify the interfaces between components against a software design. Software components may be integrated in an iterative way or all together ("big bang"). Normally the former is considered a better practice since it allows interface issues to be localized more quickly and fixed. Integration testing works to expose defects in the interfaces and interaction between the integrated components (modules). Progressively larger groups of tested software components corresponding to elements of the architectural design are integrated and tested until the software works as a system.

Technical Controls are also known as Logical Controls. These controls include the following: Implementing and maintaining access control mechanisms Password and resource management Identification and authentication methods Security devices Configuration of the infrastructure Answer: F is incorrect. It is a part of Administrative Controls.

Certification and Accreditation (C&A or CnA) is a process for implementing information security. It is a systematic procedure for evaluating, describing, testing, and authorizing systems prior to or after a system is in operation. The C&A process is used extensively in the U.S. Federal Government. Some C&A processes include FISMA, NIACAP, DIACAP, and DCID 6/3. Certification is a comprehensive assessment of the management, operational, and technical security controls in an information system, made in support of security accreditation, to determine the extent to which the controls are implemented correctly, operating as intended, and producing the desired outcome with respect to meeting the security requirements for the system. Accreditation is the official management decision given by a senior agency official to authorize operation of an information system and to explicitly accept the risk to agency operations (including mission, functions, image, or reputation), agency assets, or individuals, based on the implementation of an agreed-upon set of security controls. Answer: D is incorrect. Information Assurance (IA) is the practice of managing risks related to the use, processing, storage, and transmission of information or data and the systems and processes used for those purposes. While focused dominantly on information in digital form, the full range of IA encompasses not only digital but also analog or physical form. Information assurance as a field has grown from the practice of information security, which in turn grew out of practices and procedures of computer security.

Answer: A is incorrect. The classic information security model is used in the practice of Information Assurance (IA) to define assurance requirements. The classic information security model, also called the CIA Triad, addresses three attributes of information and information systems, confidentiality, integrity, and availability. This C-I-A model is extremely useful for teaching introductory and basic concepts of information security and assurance; the initials are an easy mnemonic to remember, and when properly understood, can prompt systems designers and users to address the most pressing aspects of assurance. Answer: B is incorrect. The Five Pillars model is used in the practice of Information Assurance (IA) to define assurance requirements. It was promulgated by the U.S. Department of Defense (DoD) in a variety of publications, beginning with the National Information Assurance Glossary, Committee on National Security Systems Instruction CNSSI-4009. Here is the definition from that publication: "Measures that protect and defend information and information systems by ensuring their availability, integrity, authentication, confidentiality, and non-repudiation. These measures include providing for restoration of information systems by incorporating protection, detection, and reaction capabilities." The Five Pillars model is sometimes criticized because authentication and non-repudiation are not attributes of information or systems; rather, they are procedures or methods useful to assure the integrity and authenticity of information, and to protect the confidentiality of the same.

The various security controls in the SDLC design phase are as follows:

Misuse Case Modeling: It is important that the inverse of the misuse cases be modeled to understand and address the security aspects of the software. The requirements traceability matrix can be used to track the misuse cases to the functionality of the software. Security Design and Architecture Review: This control can be introduced when the teams are engaged in the "functional" design and architecture review of the software. Threat and Risk Modeling: Threat modeling determines the attack surface of the software by examining its functionality for trust boundaries, data flow, entry points, and exit points. Risk modeling is performed by ranking the threats as they pertain to the users organization's business objectives, compliance and regulatory requirements and security exposures. Security Requirements and Test Cases Generation: All the above three security controls, i.e., Misuse Case Modeling, Security Design and Architecture Review, and Threat and Risk Modeling are used to produce the security requirements.

There are two types of compositional constructs: 1.External constructs: The various types of external constructs are as follows: Cascading: In this type of external construct, one system gains the input from the output of another system. Feedback: In this type of external construct, one system provides the input to another system, which in turn feeds back to the input of the first system. Hookup: In this type of external construct, one system communicates with another system as well as with external entities. 2.Internal constructs: The internal constructs include intersection, union, and difference.

The following are the responsibilities of the owner with regard to data in an information classification program: Determining what level of classification the information requires. Reviewing the classification assignments at regular time intervals and making changes as the business needs change. Delegating the responsibility of the data protection duties to a custodian. An information owner can be an executive or a manager of an organization. He will be responsible for the asset of information that must be protected. Answer: B is incorrect. Running regular backups and routinely testing the validity of the backup data is the responsibility of a custodian.

The following statements about the integrity concept of information security management are true: It ensures that modifications are not made to data by unauthorized personnel or processes. It ensures that unauthorized modifications are not made to data by authorized personnel or processes. It ensures that internal information is consistent among all subentities and also consistent with the real-world, external situation. Answer: B is incorrect. Accountability determines the actions and behaviors of an individual within a system, and identifies that particular individual. Audit trails and logs support accountability.

DIACAP describes a residual risk as the risk remaining after a risk mitigation has occurred. The Department of Defense Information Assurance Certification and Accreditation Process (DIACAP) is a process defined by the United States Department of Defense (DoD) for managing risk. DIACAP replaced the former process, known as DITSCAP (Department of Defense Information Technology Security Certification and Accreditation Process), in 2006. DoD Instruction (DoDI) 8510.01 establishes a standard DoD-wide process with a set of activities, general tasks, and a management structure to certify and accredit an Automated Information System (AIS) that will maintain the Information Assurance (IA) posture of the Defense Information Infrastructure (DII) throughout the system's life cycle.DIACAP applies to the acquisition, operation, and sustainment of any DoD system that collects, stores, transmits, or processes unclassified or classified information since December 1997. It identifies four phases: 1.System Definition 2.Verification 3.Validation 4.Re-Accreditation Answer: D is incorrect. An Information System Security Officer (ISSO) plays the role of a supporter. The responsibilities of an Information System Security Officer (ISSO) are as follows: Manages the security of the information system that is slated for Certification & Accreditation (C&A). Insures the information systems configuration with the agency's information security policy. Supports the information system owner/information owner for the completion of security-related responsibilities. Takes part in the formal configuration management process. Prepares Certification & Accreditation (C&A) packages. Answer: C is incorrect. The Designated Approving Authority (DAA), in the United States Department of Defense, is the official with the authority to formally assume responsibility for operating a system at an acceptable level of risk. The DAA is responsible for implementing system security. The DAA can grant the accreditation and can determine that the system's risks are not at an acceptable level and the system is not ready to be operational. Answer: B is incorrect. System Security Authorization Agreement (SSAA) is an information security document used in the United States Department of Defense (DoD) to describe and accredit networks and systems. The SSAA is part of the Department of Defense Information Technology Security Certification and Accreditation Process, or DITSCAP (superseded by DIACAP). The DoD instruction (issues in December 1997, that describes DITSCAP and provides an outline for the SSAA document is DODI 5200.40. The DITSCAP application manual (DoD 8510.1-M), published in July 2000, provides additional details.

The elements of security are as follows: 1.Confidentiality: It is the concealment of information or resources. 2.Authenticity: It is the identification and assurance of the origin of information. 3.Integrity: It refers to the trustworthiness of data or resources in terms of preventing improper and unauthorized changes. 4.Availability: It refers to the ability to use the information or resources as desired.

Top Secret information is the highest level of classification of material on a national level. Such material would cause "exceptionally grave damage" to national security if publicly available. Answer: A is incorrect. Secret information is that, if disclosed to unauthorized parties, could be expected to cause serious damage to the national security, but it is not the best answer for the above question. Answer: C is incorrect. Such material would cause "damage" or be "prejudicial" to national security if publicly available. Answer: B is incorrect. Unclassified information, technically, is not a classification level, but is used for government documents that do not have a classification listed above. Such documents can sometimes be viewed by those without security clearance.

NIST has developed a suite of documents for conducting Certification & Accreditation (C&A). These documents are as follows: NIST Special Publication 800-37: This document is a guide for the security certification and accreditation of Federal Information Systems. NIST Special Publication 800-53: This document provides a guideline for security controls for Federal Information Systems. NIST Special Publication 800-53A. This document consists of techniques and procedures for verifying the effectiveness of security controls in Federal Information System. NIST Special Publication 800-59: This document is a guideline for identifying an information system as a National Security System. NIST Special Publication 800-60: This document is a guide for mapping types of information and information systems to security objectives and risk levels. Answer: C is incorrect. There is no such type of NIST document.

It is the implementation phase, in which the system's security features are configured and enabled, the system is tested and installed or fielded, and the system is authorized for processing. A design review and systems test should be performed prior to placing the system into operation to ensure that it meets security specifications. Answer: B is incorrect. In Operation/Maintenance Phase, the system performs its work. The system is almost always being continuously modified by the addition of hardware and software and by numerous other events. Answer: D is incorrect. In the initiation phase, the need for a system is expressed and the purpose of the system is documented. Answer: A is incorrect. In Development/Acquisition Phase, the system is designed, purchased, programmed, developed, or otherwise constructed.

Audit trail or audit log is a chronological sequence of audit records, each of which contains evidence directly pertaining to and resulting from the execution of a business process or system function. Audit records typically result from activities such as transactions or communications by individual people, systems, accounts, or other entities. The process that creates audit trail should always run in a privileged mode, so it could access and supervise all actions from all users, and normal user could not stop/change it. Furthermore, for the same reason, trail file or database table with a trail should not be accessible to normal users. Answer: C is incorrect. A computer security audit is a manual or systematic measurable technical assessment of a system or application. Manual assessments include interviewing staff, performing security vulnerability scans, reviewing application and operating system access controls, and analyzing physical access to the systems. Automated assessments, or CAAT's, include system generated audit reports or using software to monitor and report changes to files and settings on a system. Systems can include personal computers, servers, mainframes, network routers, and switches. Answer: D is incorrect. Detective controls are the audit controls that are not needed to be restricted. Any control that performs a monitoring activity can likely be defined as a Detective Control. For example, it is possible that mistakes, either intentional or unintentional, can be made. Therefore, an additional Protective control is that these companies must have their financial results audited by an independent Certified Public Accountant. The role of this accountant is to act as an auditor. In fact, any auditor acts as a Detective control. If the organization in question has not properly followed the rules, a diligent auditor should be able to detect the deficiency which indicates that some control somewhere has failed. Answer: A is incorrect. Reactive or corrective controls typically work in response to a detective control, responding in such a way as to alert or otherwise correct an unacceptable condition. Using the example of account rules, either the internal Audit Committee or the SEC itself, based on the report generated by the external auditor, will take some corrective action. In this way, they are acting as a Corrective or Reactive control.

Documentation control is a method of ensuring that system changes should be agreed upon before being implemented, only the proposed and approved changes are implemented, and the implementation is complete and accurate. Documentation control is involved in the strict events for proposing, monitoring, and approving system changes and their implementation. It helps the change process by supporting the person who synchronizes the analytical task, approves system changes, reviews the implementation of changes, and oversees other tasks such as documenting the controls. Answer: D is incorrect. Configuration auditing is the quality assurance element of configuration management. It is occupied in the process of periodic checks to establish the consistency and completeness of accounting information and to validate that all configuration management policies are being followed. Configuration audits are broken into functional and physical configuration audits. They occur either at delivery or at the moment of effecting the change. A functional configuration audit ensures that functional and performance attributes of a configuration item are achieved, while a physical configuration audit ensures that a configuration item is installed in accordance with the requirements of its detailed design documentation. Answer: A is incorrect. Configuration control is a procedure of the Configuration management. Configuration control is a set of processes and approval stages required to change a configuration item's attributes and to re-baseline them. It supports the change of the functional and physical attributes of software at various points in time, and performs systematic control of changes to the identified attributes. Answer: C is incorrect. Configuration identification is the process of identifying the attributes that define every aspect of a configuration item. A configuration item is a product (hardware and/or software) that has an end-user purpose. These attributes are recorded in configuration documentation and baselined. Baselining an attribute forces formal configuration change control processes to be effected in the event that these attributes are changed.

Integrity refers to the ability to ensure that the data is not modified or tampered with. Integrity means that data cannot be modified without authorization. Integrity is violated when an employee accidentally or with malicious intent deletes important data files, when a computer virus infects a computer, when an employee is able to modify his own salary in a payroll database, when an unauthorized user vandalizes a Web site, when someone is able to cast a very large number of votes in an online poll, and so on. Answer: D is incorrect. Confidentiality is the property of preventing disclosure of information to unauthorized individuals or systems. Breaches of confidentiality take many forms. Permitting someone to look over your shoulder at your computer screen while you have confidential data displayed on it could be a breach of confidentiality. If a laptop computer containing sensitive information about a company's employees is stolen or sold, it could result in a breach of confidentiality. Answer: B is incorrect. Availability means that data must be available whenever it is needed. Answer: C is incorrect. Non-repudiation is the concept of ensuring that a party in a dispute cannot refuse to acknowledge, or refute the validity of a statement or contract. As a service, it provides proof of the integrity and origin of data. Although this concept can be applied to any transmission, including television and radio, by far the most common application is in the verification and trust of signatures.

The structured walk-through test is also known as the table-top exercise. In structured walk-through test, the team members walkthrough the plan to identify and correct weaknesses and how they will respond to the emergency scenarios by stepping in the course of the plan. It is the most effective and competent way to identify the areas of overlap in the plan before conducting more challenging training exercises. Answer: A is incorrect. In full-scale exercise, the critical systems run at an alternate site. Answer: B is incorrect. The emergency management group and response teams actually perform their emergency response functions by walking through the test, without actually initiating recovery procedures. But it is not much cost effective. Answer: D is incorrect. It is a test performed when personnel walks through the evacuation route to a designated area where procedures for accounting for the personnel are tested.

According to the NIST SAMATE, dynamic analysis tools operate by generating runtime vulnerability scenario using the following functions: Resource fault injection Network fault injection System fault injection User interface fault injection Design attack Implementation attack File corruption Answer: B is incorrect. This function is summarized for static analysis tools.

The Phase 2 of DITSCAP C&A is known as Verification. The goal of this phase is to obtain a fully integrated system for certification testing and accreditation. This phase takes place between the signing of the initial version of the SSAA and the formal accreditation of the system. This phase verifies security requirements during system development. The process activities of this phase are as follows: Configuring refinement of the SSAA System development Certification analysis Assessment of the Analysis Results Answer: E is incorrect. Registration is a Phase 1 activity.

Assessment, monitoring, and assurance determines the necessary compliance that are offered by risk management practices and assessment of risk levels.

The Secure Sockets Layer (SSL) is a commonly-used protocol for managing the security of a message transmission on the Internet. SSL has recently been succeeded by Transport Layer Security (TLS), which is based on SSL. SSL uses a program layer located between the Internet's Hypertext Transfer Protocol (HTTP) and Transport Control Protocol (TCP) layers. SSL is included as part of both the Microsoft and Netscape browsers and most Web server products. URLs that require an SSL connection start with https: instead of http:. Answer: C is incorrect. S/MIME (Secure/Multipurpose Internet Mail Extensions) is a standard for public key encryption and signing of e- mail encapsulated in MIME. S/MIME provides the following cryptographic security services for electronic messaging applications: authentication, message integrity, non-repudiation of origin (using digital signatures), privacy, and data security (using encryption). Answer: D is incorrect. Hypertext Transfer Protocol (HTTP) is a client/server TCP/IP protocol used on the World Wide Web (WWW) to display Hypertext Markup Language (HTML) pages. HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands. For example, when a client application or browser sends a request to the server using HTTP commands, the server responds with a message containing the protocol version, success or failure code, server information, and body content, depending on the request. HTTP uses TCP port 80 as the default port. Answer: B is incorrect. A Virtual Private Network (VPN) is a computer network that is implemented in an additional software layer (overlay) on top of an existing larger network for the purpose of creating a private scope of computer communications or providing a secure extension of a private network into an insecure network such as the Internet. The links between nodes of a Virtual Private Network are formed over logical connections or virtual circuits between hosts of the larger network. The Link Layer protocols of the virtual network are said to be tunneled through the underlying transport network.

In private cloud, the cloud infrastructure is operated exclusively for an organization. The private cloud infrastructure is administered by the organization or a third party, and exists on premise and off premise. In community cloud, the cloud infrastructure is shared by a number of organizations and supports a particular community. The community cloud infrastructure is administered by the organizations or a third party and exists on premise or off premise. Answer: B is incorrect. In public cloud, the cloud infrastructure is administered by an organization that sells cloud services. Answer: C is incorrect. In hybrid cloud, the cloud infrastructure is administered by both, i.e., an organization and a third party.

A simulation test is a method used to test the disaster recovery plans. It operates just like a structured walk-through test. In the simulation test, the members of a disaster recovery team present with a disaster scenario and then, discuss on appropriate responses. These suggested responses are measured and some of them are taken by the team. The range of the simulation test should be defined carefully for avoiding excessive disruption of normal business activities. Answer: A is incorrect. The structured walk-through test is also known as the table-top exercise. In structured walk-through test, the team members walkthrough the plan to identify and correct weaknesses and how they will respond to the emergency scenarios by stepping in the course of the plan. It is the most effective and competent way to identify the areas of overlap in the plan before conducting more challenging training exercises. Answer: B is incorrect. A full-interruption test includes the operations that shut down at the primary site and are shifted to the recovery site according to the disaster recovery plan. It operates just like a parallel test. The full-interruption test is very expensive and difficult to arrange. Sometimes, it causes a major disruption of operations if the test fails. Answer: C is incorrect. A parallel test includes the next level in the testing procedure, and relocates the employees to an alternate recovery site and implements site activation procedures. These employees present with their disaster recovery responsibilities as they would for an actual disaster. The disaster recovery sites have full responsibilities to conduct the day-to-day organization's business.

According to the Lanham Act, domain names fall under trademarks law. A new section 43(d) of the Trademark Act (Lanham Act) states that anyone who in bad faith registers, traffics in, or uses a domain name that infringes or dilutes another's trademark has committed trademark infringement. Factors involved in assessing bad faith focus on activities typically associated with cyberpiracy or cybersquatting, such as whether the registrant has offered to sell the domain name to the trademark holder for financial gain without having used or intended to use it for a bona fide business; whether the domain-name registrant registered multiple domain names that are confusingly similar to the trademarks of others; and whether the trademark incorporated in the domain name is distinctive and famous. Other factors are whether the domain name consists of the legal name or common handle of the domain-name registrant and whether the domain-name registrant previously used the mark in connection with a bona fide business.

Data remanence refers to the data that remains even after the efforts have been made for removing or erasing the data. This event occurs because of data being left intact by an insignificant file deletion operation, by storage media reformatting, or through physical properties of the storage medium. Data remanence can make unintentional disclosure of sensitive information possible. So, it is required that the storage media is released into an uncontrolled environment. Answer: C and B are incorrect. These are the made-up disasters. Answer: A is incorrect. Object reuse refers to reassigning some other object of a storage media that has one or more objects.

The Trademark law is a piece of legislation that contains the federal statutes of trademark law in the United States. The Act prohibits a number of activities, including trademark infringement, trademark dilution, and false advertising. Trademarks were traditionally protected in the United States only under State common law, growing out of the tort of unfair competition. Trademark law in the United States is almost entirely enforced through private lawsuits. The exception is in the case of criminal counterfeiting of goods. Otherwise, the responsibility is entirely on the mark owner to file suit in either state or federal civil court in order to restrict an infringing use. Failure to "police" a mark by stopping infringing uses can result in the loss of protection. Answer: D is incorrect. Copyright law of the United States governs the legally enforceable rights of creative and artistic works under the laws of the United States. Copyright law in the United States is part of federal law, and is authorized by the U.S. Constitution. The power to enact copyright law is granted in Article I, Section 8, Clause 8, also known as the Copyright Clause. This clause forms the basis for U.S. copyright law ("Science", "Authors", "Writings") and patent law ("useful Arts", "Inventors", "Discoveries"), and includes the limited terms (or durations) allowed for copyrights and patents ("limited Times"), as well as the items they may protect. In the U.S., registrations of claims of copyright, recordation of copyright transfers, and other administrative aspects of copyright are the responsibility of the United States Copyright Office, a part of the Library of Congress. Answer: A is incorrect. The Espionage Act of 1917 was a United States federal law passed shortly after entering World War I, on June 15, 1917, which made it a crime for a person: To convey information with intent to interfere with the operation or success of the armed forces of the United States or to promote the success of its enemies. This was punishable by death or by imprisonment for not more than 30 years. To convey false reports or false statements with intent to interfere with the operation or success of the military or naval forces of the United States or to promote the success of its enemies and whoever when the United States is at war, to cause or attempt to cause insubordination, disloyalty, mutiny, refusal of duty, in the military or naval forces of the United States, or to willfully obstruct the recruiting or enlistment service of the United States. Answer: C is incorrect. Cyber law is a very wide term, which wraps up the legal issue related to the use of communicative, transactional and distributive aspect of networked information device and technologies. It is commonly known as INTERNET LAW. These Laws are important to apply as Internet does not tend to make any geographical and jurisdictional boundaries clear; this is the reason why Cyber law is not very efficient. A single transaction may involve the laws of at least three jurisdictions, which are as follows: 1.The laws of the state/nation in which the user resides 2.The laws of the state/nation that apply where the server hosting the transaction is located 3.The laws of the state/nation, which apply to the person or business with whom the transaction takes place

Patent laws are used to protect the duplication of software. Software patents cover the algorithms and techniques that are used in creating the software. It does not cover the entire program of the software. Patents give the author the right to make and sell his product. The time of the patent of a product is limited though, i.e., the author of the product has the right to use the patent for only a specific length of time. Answer: D is incorrect. Copyright laws protect original works or creations of authorship including literary, dramatic, musical, artistic, and certain other intellectual works.

Residual risks are generally smaller risks that remain in the project after larger risks have been addressed. The residual risk is the risk or danger of an action or an event, a method or a (technical) process that still conceives these dangers even if all theoretically possible safety measures would be applied. The formula to calculate residual risk is (inherent risk) x (control risk) where inherent risk is (threats vulnerability). Answer: B is incorrect. This is not a valid statement about residual risks. Answer: C is incorrect. This is not a valid statement about residual risks. Answer: A is incorrect. This is not a valid statement about residual risks.

The confidentiality service of a cryptographic system ensures that information will not be disclosed to any unauthorized person on a local network.

An Intrusion detection system (IDS) is software and/or hardware designed to detect unwanted attempts at accessing, manipulating, and/or disabling of computer systems, mainly through a network, such as the Internet. These attempts may take the form of attacks, as examples, by crackers, malware and/or disgruntled employees. An IDS cannot directly detect attacks within properly encrypted traffic. An intrusion detection system is used to detect several types of malicious behaviors that can compromise the security and trust of a computer system. This includes network attacks against vulnerable services, data driven attacks on applications, host based attacks such as privilege escalation, unauthorized logins and access to sensitive files, and malware (viruses, trojan horses, and worms). Answer: D is incorrect. Access Control List (ACL) is the most commonly used object in Cisco IOS. It filters packets or network traffic by controlling whether routed packets are forwarded or blocked at the router's interfaces. According to the criteria specified within the access lists, router determines whether the packets to be forwarded or dropped. Access control list criteria could be the source or destination address of the traffic or other information. The types of Cisco ACLs are Standard IP, Extended IP, IPX, Appletalk, etc. Answer: B is incorrect. Internet Protocol Security (IPSec) is a method of securing data. It secures traffic by using encryption and digital signing. It enhances the security of data as if an IPSec packet is captured, its contents cannot be read. IPSec also provides sender verification that ensures the certainty of the datagram's origin to the receiver. Answer: A is incorrect. Direct-attached storage (DAS) is a digital storage system that is directly attached to a server or workstation, without using a storage network.

Of all the choices only this answer is accurate. The PMBOK clearly states that the data must be accurate and unbiased to be credible. Answer: D is incorrect. This is not a valid statement about the qualitative risk analysis data. Answer: A is incorrect. This is not a valid statement about the qualitative risk analysis data. Answer: B is incorrect. This is not a valid statement about the qualitative risk analysis data.

The concept of availability ensures reliable and timely access to data or resources. In other words, availability ensures that the systems are up and running when needed. The availability concept also ensures that the security services are in working order. Answer: A and D are incorrect. The concept of integrity ensures that modifications are not made to data by unauthorized personnel or processes. It also ensures that unauthorized modifications are not made to data by authorized personnel or processes. Answer: B is incorrect. Accountability determines the actions and behaviors of an individual within a system, and identifies that particular individual. Audit trails and logs support accountability.

The change management system is comprised of several components that guide the change request through the process. When a change request is made that will affect the project scope. The Configuration Management System evaluates the change request and documents the features and functions of the change on the project scope.

Designated Approving Authority (DAA) is also known as the accreditor. Answer: A is incorrect. The data owner (information owner) is usually a member of management, in charge of a specific business unit, and is ultimately responsible for the protection and use of a specific subset of information. Answer: B is incorrect. A Chief Risk Officer (CRO) is also known as Chief Risk Management Officer (CRMO). The Chief Risk Officer or Chief Risk Management Officer of a corporation is the executive accountable for enabling the efficient and effective governance of significant risks, and related opportunities, to a business and its various segments. Risks are commonly categorized as strategic, reputational, operational, financial, or compliance-related. CRO's are accountable to the Executive Committee and The Board for enabling the business to balance risk and reward. In more complex organizations, they are generally responsible for coordinating the organization's Enterprise Risk Management (ERM) approach. Answer: C is incorrect. The Chief Information Officer (CIO), or Information Technology (IT) director, is a job title commonly given to the most senior executive in an enterprise responsible for the information technology and computer systems that support enterprise goals. The CIO plays the role of a leader and reports to the chief executive officer, chief operations officer, or chief financial officer. In military organizations, they report to the commanding officer.

The Recovery Time Objective (RTO) is the duration of time and a service level within which a business process must be restored after a disaster or disruption in order to avoid unacceptable consequences associated with a break in business continuity. It includes the time for trying to fix the problem without a recovery, the recovery itself, tests and the communication to the users. Decision time for user representative is not included. The business continuity timeline usually runs parallel with an incident management timeline and may start at the same, or different, points. In accepted business continuity planning methodology, the RTO is established during the Business Impact Analysis (BIA) by the owner of a process (usually in conjunction with the Business Continuity planner). The RTOs are then presented to senior management for acceptance. The RTO attaches to the business process and not the resources required to support the process. Answer: B is incorrect. The Recovery Time Actual (RTA) is established during an exercise, actual event, or predetermined based on recovery methodology the technology support team develops. This is the time frame the technology support takes to deliver the recovered infrastructure to the business. Answer: D is incorrect. The Recovery Consistency Objective (RCO) is used in Business Continuity Planning in addition to Recovery Point Objective (RPO) and Recovery Time Objective (RTO). It applies data consistency objectives to Continuous Data Protection services. Answer: C is incorrect. The Recovery Point Objective (RPO) describes the acceptable amount of data loss measured in time. It is the point in time to which data must be recovered as defined by the organization. The RPO is generally a definition of what an organization determines is an "acceptable loss" in a disaster situation. If the RPO of a company is 2 hours and the time it takes to get the data back into production is 5 hours, the RPO is still 2 hours. Based on this RPO the data must be restored to within 2 hours of the disaster.
