is incorrect. Risk mitigation attempts to reduce the probability of a risk event and its
impacts to an acceptable level. Risk mitigation can utilize various forms of control carefully
integrated together.

The most important thing when implementing an organization's security policy is to obtain management support. Management support means that the senior management and the board of directors endorse, approve, and fund the security policy and its implementation. Management support also means that the management communicates, promotes, and enforces the security policy across the organization. Management support can help to ensure that the security policy is aligned with the organizational strategy and objectives, and that it is effective, consistent, and sustainable. The other options are not as important as obtaining management support, as they are related to the specific aspects or components of the security policy implementation, not the overall success and acceptance of the security policy implementation.

* A retention policy is a set of rules and guidelines that define how long and under what conditions the information should be kept or disposed of by the organization, based on its value, sensitivity, and legal or regulatory requirements.
* When information is no longer required to support business objectives, the first thing that should be done is to assess the information against the retention policy. This means that the information should be reviewed and evaluated to determine if it should be retained or deleted, and for how long and by whom.
* Assessing the information against the retention policy helps to ensure that the information is managed and disposed of in a consistent and compliant manner, that the information is protected from unauthorized access, use, disclosure, modification, or destruction, and that the information is available for future reference or audit purposes if needed.
* The other options are not the first things that should be done when information is no longer required to support business objectives. They are either secondary or not essential for information management.

Role-based access controls (RBAC) are a type of preventive control that limit the access and actions of users based on their roles and responsibilities within the organization. RBAC can help to address the risk of malicious outsiders modifying application data by restricting their access to the data and the functions they can perform on it. RBAC can also enforce the principle of least privilege, which means that users only have the minimum level of access required to perform their tasks. RBAC can be implemented through policies, procedures, and technical mechanisms such as access control lists, encryption, and authentication.
