Isaca Certification CISM Isaca Study Notes

The greatest challenge with assessing emerging risk in an organization is the incomplete identification of threats, as emerging risks are often new, unknown, or unfamiliar, and may not be fully understood or assessed. Incomplete identification of threats can lead to gaps in risk analysis and management, and expose the organization to unexpected or unprepared scenarios. The other options, such as lack of a risk framework, ineffective security controls, or presence of known vulnerabilities, are not specific to emerging risks, and may apply to any type of risk assessment.

= Continuous monitoring is the process of collecting, analyzing, and reporting on the security status of an organization’s information systems and networks. Continuous monitoring enables an organization to identify and contain security incidents by providing timely and accurate information on the security events, alerts, incidents, and threats that may affect the organization. Continuous monitoring also helps to measure the effectiveness and compliance of the security controls, policies, and procedures that are implemented to protect the organization’s information assets. Continuous monitoring can be performed using various tools and methods, such as security information and event management (SIEM) tools, intrusion detection and prevention systems (IDS/IPS), vulnerability scanners, log analyzers, and audit trails.

 The information security manager’s first course of action should be to validate the relevance of the information received from the threat intelligence service. This means verifying the source, credibility, accuracy, and timeliness of the information, as well as assessing the potential impact and likelihood of the threat for the organization. This will help the information security manager to determine the appropriate response and prioritize the actions to mitigate the threat. Conducting an information security audit, performing a gap analysis, and informing senior management are possible subsequent actions, but they are not the first course of action. An information security audit is a systematic and independent assessment of the effectiveness of the information security controls and processes. A gap analysis is a comparison of the current state of the information security program with the desired state or best practices. Informing senior management is a communication activity that should be done after validating the information and assessing the risk. References = CISM Review Manual, 16th Edition, pages 44-451; CISM Review Questions, Answers & Explanations Manual, 10th Edition, page 632

The first step the information security manager should take upon learning of the potential threat is to validate the relevance of the information. This should involve researching the threat to evaluate its potential impact on the organization and to determine the accuracy of the threat intelligence. Once the information is validated, the information security manager can then take action, such as informing senior management, conducting an information security audit, or performing a gap analysis.

Performing a gap analysis is the first step to ensure the security policy framework encompasses the new business model because it is a process of comparing the current state of security policies and controls with the desired or required state. A gap analysis helps to identify the strengths and weaknesses of the existing security policy framework, as well as the opportunities and threats posed by the new business model. A gap analysis also helps to prioritize the actions and resources needed to close the gaps and align the security policy framework with the new business objectives and requirements. Therefore, performing a gap analysis is the correct answer.
