A. Conduct surveys and rank the results.
B. Perform routine user permission reviews.

Risk mitigation is accomplished any time you take steps to reduce risk. This category includes installing antivirus software, educating users about possible threats, monitoring network traffic, adding a firewall, and so on. User permissions may be the most basic aspect of security and is best coupled with a principle of least privilege. And related to permissions is the concept of the access control list (ACL). An ACL is literally a list of who can access what resource and at what level. Thus the best risk mitigation steps insofar as access control rights are concerned, is the regular/routine review of user permissions.

A. User rights and permissions review
B. Configuration management
C. Incident management
D. Implement security controls on Layer 3 devices
