Implementation guidance
Editorial examples to help you plan. Adapt them to your environment; the official requirement and objectives remain authoritative.
In plain language
Develop and implement plans to correct deficiencies and reduce vulnerabilities.
Implementation example
Example from the source assessment guide (not a mandatory implementation): As IT director, one of your duties is to develop action plans when you discover that your company is not meeting security requirements or when a security issue arises [b]. A recent vulnerability scan identified several items that need to be addressed so you develop a plan to fix them [b]. Your plan identifies the people responsible for fixing the issues, how to do it, and when the remediation will be completed [b]. You also define how to verify that the person responsible has fixed the vulnerability [b]. You document this in an operational plan of action that is updated as milestones are reached [b]. You have a separate resource review the modifications after they have been completed to ensure the plan has been implemented correctly [c].
Evidence examples
Examples suggested by the source guide (not an exhaustive or mandatory checklist): Security assessment and authorization policy; procedures addressing plan of action; system security plan; security assessment plan; security assessment report; security assessment evidence; plan of action; other relevant documents or records
Common mistakes
