RA-5(3)—Vulnerability Monitoring and Scanning | Breadth and Depth of Coverage
>Control Description
>DoD Impact Level Requirements
No specific parameter values or requirements for this impact level.
>Discussion
The breadth of vulnerability scanning coverage can be expressed as a percentage of components within the system, by the particular types of systems, by the criticality of systems, or by the number of vulnerabilities to be checked. Conversely, the depth of vulnerability scanning coverage can be expressed as the level of the system design that the organization intends to monitor (e.g., component, module, subsystem, element). Organizations can determine the sufficiency of vulnerability scanning coverage with regard to its risk tolerance and other factors.
Scanning tools and how the tools are configured may affect the depth and coverage. Multiple scanning tools may be needed to achieve the desired depth and coverage. SP 800-53A provides additional information on the breadth and depth of coverage.
