Title

The SSLHonorCipherOrder DWORD must be configured to disable weak encryption algorithms on the Tanium Server. (Cat II impact)

Discussion

Use of weak or untested encryption algorithms undermines the purposes of utilizing encryption to protect data. The application must implement cryptographic modules adhering to the higher standards approved by the federal government since this provides assurance they have been tested and validated.
