Correct Answer: D

A checklist test is a test in which the disaster recovery checklists are distributed to the members of the disaster recovery team. All members are asked to review the assigned checklist. The checklist test is a simple test and it is easy to conduct this test. It allows to accomplish the following three goals: It ensures that the employees are aware of their responsibilities and they have the refreshed knowledge. It provides an individual with an opportunity to review the checklists for obsolete information and update any items that require modification during the changes in the organization. It ensures that the assigned members of disaster recovery team are still working for the organization. Answer: B is incorrect. 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. 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. Answer: C 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.

Correct Answer: C

In order to accomplish the task, you should limit the number of Syslog messages or TCP connections from a specific source for a certain time period. This will prevent a denial of service (DoS) for the Syslog server and the loss of Syslog messages from other sources. Answer: D is incorrect. You can encrypt rotated log files automatically using third-party or OS mechanisms to protect data confidentiality. Answer: A is incorrect. You can use a different message format other than Syslog in order to accept data for aggregating data from hosts that do not support Syslog. Answer: B is incorrect. You can enable the storage of log entries in both traditional Syslog files and a database for creating a database storage for logs.

Correct Answer: AC

The Biba and Clark-Wilson access control models are used in the commercial sector. The Biba model is a formal state transition system of computer security policy that describes a set of access control rules designed to ensure data integrity. Data and subjects are grouped into ordered levels of integrity. The model is designed so that subjects may not corrupt data in a level ranked higher than the subject, or be corrupted by data from a lower level than the subject. The Clark-Wilson security model provides a foundation for specifying and analyzing an integrity policy for a computing system. Answer: D is incorrect. The Bell-LaPadula access control model is mainly used in military systems. Answer: B is incorrect. There is no such access control model as Clark-Biba.

Correct Answer: BDE

Continuous Monitoring is the fourth phase of the security certification and accreditation process. The Continuous Monitoring process consists of the following three main activities: Configuration management and control Security control monitoring and impact analyses of changes to the information system Status reporting and documentation The objective of these tasks is to observe and evaluate the information system security controls during the system life cycle. These tasks determine whether the changes that have occurred will negatively impact the system security. Answer: A and C are incorrect. Security accreditation decision and security accreditation documentation are the two tasks of the security accreditation phase.

Correct Answer: AD

C and C++ programming languages are unmanaged code. Unmanaged code is compiled into machine code and directly executed by the CPU of a computer system. Answer: C and B are incorrect. Java EE and Microsoft.Net are compiled into an intermediate code format.

Correct Answer: D

Quantitative risk analysis is the process of numerically analyzing the effect of identified risks on overall project objectives. It is performed on risk that have been prioritized through the qualitative risk analysis process. Answer: A is incorrect. This is actually the definition of qualitative risk analysis. Answer: B is incorrect. While somewhat true, this statement does not completely define the quantitative risk analysis process. Answer: C is incorrect. This is not a valid statement about the quantitative risk analysis process. Risk response planning is a separate project management process.

Correct Answer: C

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.

Correct Answer: D

Preventive controls are the security controls that are intended to prevent an incident from occurring, e.g., by locking out unauthorized intruders. Answer: C is incorrect. Detective controls are intended to identify and characterize an incident in progress, e.g., by sounding the intruder alarm and alerting the security guards or police. Answer: A is incorrect. Corrective controls are intended to limit the extent of any damage caused by the incident, e.g., by recovering the organization to normal working status as efficiently as possible. Answer: B is incorrect. There is no such categorization of controls based on time.

Correct Answer: ACDF

The security policy of a software system addresses the following important areas:

Access control Data protection Confidentiality Integrity Identification and authentication Communication security Accountability Answer: E and B are incorrect. Scalability and punctuality are not addressed by a software system's security

policy.

Correct Answer: C

CandA 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 and Accreditation (CandA). 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.
