Ongoing maintenance must be an important concern during and after the security implementation. This maintenance can take the form of updates to the CA Top Secret Security File as well as maintenance to the CA Top Secret software itself. It is important that your maintenance procedures be in place so that the approach is defined in anticipation of the first request.
If you have chosen a gradual approach to security implementation, implementing functional areas and facilities one at a time, maintenance becomes a requirement before the implementation is completed. Your maintenance procedures can be designed to anticipate these requirements.
As your environment changes, as is common in most installations, you are required to revise your security definitions to reflect these changes. It is important to determine that the changes to security definitions are both necessary and legitimate. For this reason, you can have a CA Top Secret Security File maintenance procedure which allows you to ensure that the requested revisions are correct and authorized.
