The results of a risk assessment would best enable an informed decision by senior management when developing a business case to justify an information security investment. A risk assessment will help to identify and prioritize the threats and vulnerabilities that affect the organization's assets and processes, as well as the potential impact and likelihood of occurrence. A risk assessment will also provide a basis for selecting and evaluating the effectiveness of controls to mitigate the risks. According to CISA, developing a business case for security will be based on an in-depth understanding of organizational vulnerabilities, operational priorities, and return on investment1. The information security strategy, losses due to security incidents, and security investment trends in the industry are possible inputs or outputs of a risk assessment, but they are not sufficient to enable an informed decision by senior management.

Identify and assess the risk in the context of business objectives. Before making any changes to the security policy or introducing any new controls, the information security manager should first identify and assess the risk that the new privacy regulation poses to the business. This should be done in the context of the overall business objectives so that the security measures introduced are tailored to meet the specific needs of the organization.

Reviewing the provider's incident definitions and notification criteria is the FIRST course of action when aligning the organization's incident response capability with a public cloud service provider. This is because the organization needs to understand how the provider defines and classifies incidents, what their roles and responsibilities are, and how they will communicate with the organization in case of an incident. This will help the organization align its own incident response processes and expectations with the provider's and ensure a coordinated and effective response.

"A successful security program requires management support and involvement. One of the key aspects of management support is to decide on the value of assets and the acceptable level of risk for them. This will help define the security objectives and priorities for the program. The other options are possible activities within a security program, but they are not as important as management decision on asset value."
