The primary reason for an organization to include an acceptable use banner when users log in is to reduce the likelihood of insider threat, as it informs the users of the policies, rules, and expectations for the use of the organization’s IT resources, and deters them from engaging in unauthorized or malicious activities. The other options are not the primary reasons, as they are more related to the detection, prevention, or mitigation of insider threat, respectively, rather than the reduction of the likelihood of insider threat. References = CRISC Review Manual, 7th Edition, page 155.

Restricting access to the risk register on a need-to-know basis is important because it contains vulnerabilities and threats that could expose the organization to potential harm or loss if they are disclosed or exploited by unauthorized parties. The risk register is a tool that captures and documents the risk identification, analysis, evaluation, and treatment processes1. The risk register contains sensitive information such as the sources and causes of risk, the potential impacts and consequences of risk, the likelihood and frequency of risk occurrence, and the risk response actions and plans1. If this information is accessed by unauthorized parties, such as competitors, hackers, or malicious insiders, they could use it to launch attacks, sabotage operations, or gain an unfair advantage over the organization. Therefore, access to the risk register should be limited to those who have a legitimate need and authorization to view, modify, or use the information, such as the risk owners, managers, or practitioners

The best option to protect against a future recurrence of unauthorized access by a service provider’s administrator is D. Contractual requirements. Data encryption, intrusion prevention system, and two-factor authentication are all technical measures that can enhance the security of the data stored in the Infrastructure as a Service (IaaS) model, but they do not prevent the service provider’s administrator from accessing the data if they have the necessary credentials, keys, or permissions. Contractual requirements, on the other hand, are legal obligations that bind the service provider to respect the customer’s privacy and confidentiality, and to limit the access to the data to only authorized and necessary personnel. Contractual requirements can also specify the penalties or remedies for any breach of contract, which can deter the service provider’s administrator from violating the terms of the agreement. Therefore, contractual requirements are the most effective way to protect against a future recurrence of unauthorized access by a service provider’s administrator12

Business Impact Analysis (BIA):

Objective: The primary objective of a BIA is to identify and evaluate the effects of disruptions on business operations. This includes determining the criticality of IT assets that support key business processes.

Risk Mitigation: By identifying critical IT assets, organizations can prioritize risk mitigation efforts to ensure that key business processes remain operational during and after disruptions.

Appropriate IT Risk Mitigation:

Critical Asset Identification: Knowing which IT assets are essential allows for targeted risk mitigation strategies. This ensures resources are allocated efficiently to protect the most important systems.

Impact Assessment: Understanding the impact of potential disruptions on critical IT assets helps in developing effective disaster recovery and continuity plans.

Comparison with Other Options:

Validating Critical IT Risk: While important, this is typically part of a broader BIA process rather than its primary objective.

Assigning Accountability for IT Risk: This is crucial for governance but does not directly enable risk mitigation actions.

Defining IT Risk-aware Culture: Important for overall risk management but does not directly influence specific mitigation actions.

Best Practices:

Detailed Asset Inventory: Maintain an up-to-date inventory of IT assets and their dependencies on business processes.

Regular Updates and Reviews: Continuously update the BIA to reflect changes in the IT environment and business processes.
