In the PDCA cycle, the "Plan" phase is where targets and objectives are defined. Focusing on this phase allows the auditor to evaluate the accuracy and appropriateness of the defined targets before they are implemented and measured in subsequent phases.

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:
