The various principle documents of transformation are as follows: CNSSP 22: It establishes a national risk management policy for national security systems. CNSSI 1199: It creates the technique in which the national security community classifies the information and information systems with regard to confidentiality, integrity, and availability. CNSSI 1253: It combines DCID 6/3, DOD Instructions 8500.2, NIST SP 800-53, and other security sources into a single cohesive repository of security controls. CNSSI 1253 A.
It offers the techniques to assess adequacy of each security control. CNSSI 1260: It provides guidance to organizations with the characterization of their information and information systems. NIST 800-37, Revision 1: It defines the certification and accreditation (C & A) process. The NIST 800-37, Revision 1 is a combination of DNI, DoD, and NIST.

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

Explanation: 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. AnswerD 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.

A contingency plan is a plan devised for a specific situation when things could go wrong. Contingency plans include specific strategies and actions to deal with specific variances to assumptions resulting in a particular problem, emergency, or state of affairs. They also include a monitoring process and triggers for initiating planned actions. Answer A is incorrect. Disaster recovery is the process, policies, and procedures related to preparing for recovery or continuation of technology infrastructure critical to an organization after a natural or human-induced disaster. Answer B is incorrect. It deals with the plans and procedures that identify and prioritize the critical business functions that must be preserved. Answer C is incorrect. It includes the plans and procedures documented that ensure the continuity of critical operations during any period where normal operations are impossible.
