A monitored mantrap at entrance and exit points would be the most effective compensating control in this scenario. A mantrap is a physical security access control system comprising a small space having two sets of interlocking doors such that the first set of doors must close before the second set opens. By implementing a monitored mantrap, unauthorized access can be prevented and it can ensure that all individuals are logged when they enter and exit the server room12.

Quarterly steering committee meetings best demonstrate alignment of the IT department with the corporate mission because they provide a regular forum for strategic planning, decision making, and communication between IT leaders and business stakeholders12. Steering committee meetings help to ensure that IT goals and initiatives are aligned with the business vision, mission, and objectives, and that IT performance and value are monitored and evaluated34.

Capacity management tools are primarily used to ensure that available resources are used efficiently and effectively to meet the current and future demands of the business. Capacity management tools can help monitor, analyze and optimize the performance and utilization of IT resources such as CPU, memory, disk, network, etc. The other options are not the primary purpose of capacity management tools, although they may be related or derived from them.

An IT risk assessment is the process of identifying and assessing the threats facing an organization's information systems, networks, and data. An IT risk assessment helps an organization to understand its current risk profile, prioritize its risks, and implement appropriate controls to mitigate them. An IT risk assessment also helps an organization to comply with relevant laws and standards, such as ISO 27001 or CMMC.
One of the key steps in an IT risk assessment is the identification of vulnerabilities. Vulnerabilities are the weaknesses or gaps in an organization's information security that could be exploited by internal or external threats. Vulnerabilities can exist in various aspects of an organization's information security, such as:
* Hardware: The physical devices and components that store or process information
* Software: The applications and programs that run on hardware devices
* Network: The communication channels and protocols that connect hardware devices
* Data: The information that is stored or transmitted by hardware devices or software applications
* People: The users or personnel who access or manage information systems or data
* Processes: The procedures or workflows that govern how information systems or data are used or maintained By identifying vulnerabilities in each of these aspects, an organization can assess its exposure to potential threats, such as hackers, malware, natural disasters, human errors, or sabotage. By identifying vulnerabilities, an organization can also determine its risk level for each threat scenario, based on the likelihood and impact of a successful attack. By identifying vulnerabilities, an organization can also identify the existing or required controls to prevent or reduce the impact of an attack.
Therefore, an IT risk assessment should include the identification of vulnerabilities as a crucial component.
