Discussion [NIST SP 800-171 R2]
Vulnerabilities discovered, for example, via the scanning conducted in response to RA.L2-3.11.2, are remediated with consideration of the related assessment of risk. The consideration of risk influences the prioritization of remediation efforts and the level of effort to be expended in the remediation for specific vulnerabilities.
Not all vulnerabilities captured in a vulnerability scanner may pose the same level of risk to an organization. Prioritize mitigation efforts to close the most critical vulnerabilities first. Track all vulnerability remediation to ensure completion; also track vulnerabilities that you have determined not to remediate.
This practice, RA.L2-3.11.3, benefits from CA.L2-3.12.2. RA.L2-3.11.3 allows remediation of vulnerabilities to take place based on the developed plans of actions for vulnerabilities from CA.L2-3.12.2.
