 A system electronic log is the most useful source of information for an IS auditor to review all access attempts to a video-monitored and proximity card-controlled communications room. A system electronic log can provide accurate and detailed records of the date, time, card number, and status (success or failure) of each access attempt. A system electronic log can also be easily searched, filtered, and analyzed by the auditor to identify any unauthorized or suspicious access attempts.

A manual sign-in and sign-out log is not as reliable or useful as a system electronic log, because it depends on the honesty and compliance of the users. A manual log can be easily manipulated, forged, or omitted by the users or intruders. A manual log also does not capture the status of each access attempt, and it can be difficult to verify the identity of the users based on their signatures.

An alarm system with CCTV is not as useful as a system electronic log, because it only captures the events that trigger the alarm, such as unauthorized or forced entry. An alarm system with CCTV does not provide a complete record of all access attempts, and it can be affected by factors such as camera angle, lighting, and resolution. An alarm system with CCTV also requires more time and effort to review the video footage by the auditor.

A security incident log is not as useful as a system electronic log, because it only records the incidents that are reported by the users or detected by the security staff. A security incident log does not provide a comprehensive record of all access attempts, and it can be incomplete or inaccurate depending on the reporting and detection mechanisms. A security incident log also does not capture the details of each access attempt, such as the card number and status.

The most concerning issue associated with a data center’s CCTV surveillance cameras is that the recordings are not regularly reviewed. This means that any unauthorized access, theft, vandalism, or other security incidents may go unnoticed and unreported. CCTV recordings are a valuable source of evidence and deterrence for data center security, and they should be monitored and audited periodically to ensure compliance with policies and regulations. If the recordings are not reviewed, the data center may face legal, financial, or reputational risks in case of a security breach or an audit failure.

The other options are less concerning because they do not directly affect the security of the data center. CCTV cameras are not required to be installed in break rooms, as they are not critical areas for data protection. CCTV records can be deleted after one year, as long as they comply with the data retention policy of the organization and the applicable laws. CCTV footage does not need to be recorded 24 x 7,as long as there is sufficient coverage of the data center during operational hours and when access is granted to authorized personnel. References:

The best evidence that an organization’s IT strategy is aligned to its business objectives is that the IT strategy is approved by executive management. This implies that the IT strategy has been reviewed and validated by the senior leaders of the organization, who are responsible for setting and overseeing the business objectives. The IT strategy may be modified inresponse to organizational change, based on IT operational best practices, or have significant impact on the business strategy, but these are not sufficient indicators of alignment without executive approval. References: CISA Review Manual (Digital Version)1, Chapter 1, Section 1.2.1

Linking incidents to problem management activities would most effectively help to reduce the number of repeated incidents in an organization, because problem management aims to identify and eliminate the root causes of incidents and prevent their recurrence. Testing incident response plans, prioritizing incidents, and training incident management teams are all good practices, but they do not directly address the issue of repeated incidents. References: ISACA ITAF 3rd Edition Section 3600
