Isaca CISM Questions Answers

Escalate to senior management, because this could help the information security manager to inform the decision-makers of the situation, explain the implications and trade-offs, and seek their guidance and approval for the next steps2. However, this answer is not certain, and you might need to consider other factors as well.

The explanation given in the manual is:

Incident classification criteria enable an organization to prioritize incidents based on their impact and urgency. This allows for an optimized allocation of recovery resources to minimize business disruption and ensure timely restoration of normal operations. The other choices are benefits of incident management but not directly related to incident classification criteria.

The primary benefit of establishing a clear definition of a security incident is that it helps to develop effective escalation and response procedures. A security incident is an event or an attempt that disrupts or threatens the normal operations, security, or privacy of an organization’s information or systems1. A clear definition of a security in-cident helps to:

•Distinguish between normal and abnormal events, and between security-relevant and non-security-relevant events

•Determine the severity and impact of an incident, and the appropriate level of response

•Assign roles and responsibilities for incident detection, reporting, analysis, containment, eradication, recovery, and post-incident activities

•Establish criteria and thresholds for escalating incidents to higher authorities or external parties

•Define the communication channels and protocols for incident notification and coordina-tion

•Document the incident response process and procedures in a formal plan

According to NIST, a clear definition of a security incident is one of the key compo-nents of an effective incident response capability2. The other options are not the prima-ry benefits of establishing a clear definition of a security incident. Communicating the incident response process to stakeholders is important, but it is not the main purpose of defining a security incident. Adequately staffing and training incident response teams is essential, but it depends on other factors besides defining a security inci-dent. Making tabletop testing more effective is a possible outcome, but not a direct benefit of defining a security incident.

 Defining information security requirements and processes is the FIRST thing that the information security manager should do to support the initiative of utilizing Software as a Service (SaaS) and selecting a vendor. This is because information security requirements and processes provide the basis for evaluating and comparing the SaaS vendors and solutions, as well as for ensuring the alignment of the SaaS services with the organization’s security objectives, policies, and standards. Information security requirements and processes should include aspects such as data protection, access control, encryption, authentication, authorization, audit, compliance, incident response, disaster recovery, and service level agreements12. Reviewing independent security assessment reports for each vendor (A) is a useful thing to do to support the initiative of utilizing SaaS and selecting a vendor, but it is not the FIRST thing to do. Independent security assessment reports can provide valuable information about the security posture, practices, and performance of the SaaS vendors and solutions, such as their compliance with industry standards, frameworks, and regulations, their vulnerability and risk management, and their security testing and auditing results. However, reviewing independent security assessment reports should be done after defining the information security requirements and processes, which can help to determine the scope, criteria, and expectations for the security assessment12. Benchmarking each vendor’s services with industry best practices (B) is also a useful thing to do to support the initiative of utilizing SaaS and selecting a vendor, but it is not the FIRST thing to do. Benchmarking each vendor’s services with industry best practices can help to measure and compare the quality, performance, and value of the SaaS vendors and solutions, as well as to identify the gaps, strengths, and weaknesses of the SaaS services. However, benchmarking each vendor’s services with industry best practices should be done after defining the information security requirements and processes, which can help to select the relevant and appropriate industry best practices for the SaaS services12. Analyzing the risks and proposing mitigating controls © is also a useful thing to do to support the initiative of utilizing SaaS and selecting a vendor, but it is not the FIRST thing to do. Analyzing the risks and proposing mitigating controls can help to identify and evaluate the potential threats, vulnerabilities, and impacts that may affect the security, availability, and reliability of the SaaS vendors and solutions, as well as to recommend and implement the necessary measures to reduce or eliminate the risks. However, analyzing the risks and proposing mitigating controls should be done after defining the information security requirements and processes, which can help to establish the risk appetite, tolerance, and criteria for the SaaS services12. References = 1: CISM Review Manual 15th Edition, page 82-831; 2: How to Evaluate SaaS Providers and Solutions by Developing RFP Criteria - Gartner2
