In accordance with Do DI 8510.01 (ref d), "systems that have been evaluated as having a sufficiently robust system-level continuous monitoring program (as defined by emerging Do D continuous monitoring policy) may operate under a continuous reauthorization." AOs who determine that their DISN connected enclave has met Do D’s continuous monitoring policy requirements are still required to update their respective ATO at a minimum of every three (3) years before a new ATC/IATC will be issued.
Legacy SGS is not updated and does not contain current information.
At some point in the near future, the Legacy SGS system will be removed.
