According to the CISM Review Manual, 15th Edition1, information asset classification is the process of assigning a level of sensitivity to information assets based on their importance to the organization and the potential impact of unauthorized disclosure, modification or destruction. The criticality of an information asset to a business process is one of the key factors that determines its classification level.

The best way to ensure the effective execution of a disaster recovery plan (DRP) is to make sure that the procedures are available at both the primary and the failover location, so that the staff can access them in case of a disaster. The procedures should be clear, concise, and updated regularly to reflect the current situation and requirements. Having the procedures available at both locations also helps to avoid confusion and delays in the recovery process.

According to the CISM Review Manual, one of the primary roles of the information security manager in application development is to ensure that security is integrated into the SDLC. This means that security requirements, design, testing, deployment, and maintenance are all considered and addressed throughout the application development process. By doing so, the information security manager can help to prevent or mitigate security risks, ensure compliance with standards and regulations, and improve the quality and reliability of the application1 The other options are not as accurate as ensuring security is integrated into the SDLC. Ensuring compliance with industry best practices is a secondary role of the information security manager in application development, as it involves following established guidelines and frameworks for secure application development. However, compliance alone does not guarantee that security is actually implemented in the application. Ensuring enterprise security controls are implemented is a tertiary role of the information security manager in application development, as it involves applying existing policies and procedures for managing and monitoring security activities across the organization. However, enterprise controls alone do not ensure that security is tailored to the specific needs and context of each application. Ensuring control procedures address business risk is a quaternary role of the information security manager in application development, as it involves identifying and assessing potential threats and vulnerabilities that could affect the business objectives and operations of each application. However, business risk alone does not ensure that security measures are aligned with the value proposition and benefits of each application1 References = 1: CISM Review Manual, 16th Edition, ISACA, 2020, pp. 30-31...
