The most important thing to determine during the planning phase of a cloud-based messaging and collaboration platform acquisition is the types of data that can be uploaded to the platform. This is because different types of data may have different security, privacy, and compliance requirements, depending on the nature, sensitivity, and value of the data. For example, personal data, financial data, health data, or intellectual property data may be subject to various laws and regulations that govern how they can be collected, stored, processed, and shared in the cloud. Therefore, it is essential to identify and classify the types of data that will be uploaded to the platform, and ensure that the platform meets the organization’s policies and standards for data protection1.

The other options are not as important as the types of data that can be uploaded to the platform during the planning phase of a cloud-based messaging and collaboration platform acquisition. Option A, role-based access control policies, is a mechanism that defines who can access what data and resources on the platform based on their roles and responsibilities. Role-based access control policies are important for ensuring data security and accountability, but they can be designed and implemented after the platform is acquired2. Option C, processes for on-boarding and off-boarding users to the platform, are procedures that enable or disable user accounts and access rights on the platform. Processes for on-boarding and off-boarding users are important for managing user identities and lifecycles, but they can be developed and executed after the platform is acquired3. Option D, processes for reviewing administrator activity, are methods that monitor and audit the actions and events performed by administrators on the platform. Processes for reviewing administrator activity are important for detecting and preventing unauthorized or malicious activities, but they can be established and performed after the platform is acquired4.

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 most critical factor for the effective implementation of IT governance is a supportive corporate culture. A supportive corporate culture is one that fosters collaboration, communication and commitment among all stakeholders involved in IT governance processes. A supportive corporate culture also promotes a shared vision, values and goals for IT governance across the organization. Strong risk management practices, internal auditor commitment or documented policies are important elements for IT governance implementation, but they are not sufficient without a supportive corporate culture. References: ISACA, CISA Review Manual, 27th Edition, 2018, page 41

The first task that an IS auditor should complete during the preliminary planning phase of a database security review is to determine which databases will be in scope. The scope defines the boundaries and objectives of the audit, as well as the resources, time, and budget required. The IS auditor should identify the databases that are relevant to the audit based on factors such as their criticality, risk, complexity, size, type, location, and ownership. The IS auditor should also consider the regulatory, contractual, and organizational requirements that apply to the databases. By defining the scope clearly and accurately, the IS auditor can ensure that the audit is focused, feasible, and effective. References:
