Which of the following should be given the HIGHEST priority during an information security post- incident review?
Correct Answer: A
Question 622
The fundamental purpose of establishing security metrics is to:
Correct Answer: B
Explanation Security metrics are used to measure the effectiveness of controls and evaluate the overall security posture of an organization. This feedback provides an understanding of the progress made towards achieving security objectives and allows organizations to make necessary adjustments.
Question 623
Which of the following BEST ensures timely and reliable access to services?
Correct Answer: C
= According to the CISM Review Manual, availability is the degree to which information and systems are accessible to authorized users in a timely and reliable manner1. Availability ensures that services are delivered to the users as expected and agreed upon. Nonrepudiation is the ability to prove the occurrence of a claimed event or action and its originating entities1. It ensures that the parties involved in a transaction cannot deny their involvement. Authenticity is the quality or state of being genuine or original, rather than a reproduction or fabrication1. It ensures that the identity of a subject or resource is valid. Recovery time objective (RTO) is the maximum acceptable period of time that can elapse before the unavailability of a business function severely impacts the organization1. It is a metric used to measure the recovery capability of a system or service, not a factor that ensures timely and reliable access to services.

Question 624
Threat and vulnerability assessments are important PRIMARILY because they are:
Correct Answer: B
Explanation Threat and vulnerability assessments are important primarily because they are the basis for setting control objectives. Control objectives are the desired outcomes of implementing security controls, and they should be aligned with the organization's risk appetite and business objectives. Threat and vulnerability assessments help to identify the potential sources and impacts of security incidents, and to prioritize the mitigation actions based on the likelihood and severity of the risks. By conducting threat and vulnerability assessments, the organization can establish the appropriate level and type of security controls to protect its information assets and reduce the residual risk to an acceptable level.

Threat and vulnerability assessments are important PRIMARILY because they are the basis for setting control objectives. Control objectives are the desired outcomes or goals of implementing security controls in an information system. They are derived from the risk assessment process, which identifies and evaluates the threats and vulnerabilities that could affect the system's confidentiality, integrity and availability. By conducting threat and vulnerability assessments, an organization can determine the level of risk it faces and establish the appropriate control objectives to mitigate those risks.
Question 625
Which of the following presents the GREATEST exposure to internal attack on a network?
Correct Answer: C
Explanation/Reference: Explanation: When passwords are sent over the internal network in an encoded format, they can easily be converted to clear text. All passwords should be encrypted to provide adequate security. Not automatically expiring user passwords does create an exposure, but not as great as having unencrypted passwords. Using a single switch or subnet does not present a significant exposure.
