Notes

Further mitigations: Administrators should be instructed to stictly comparmentalize their computing activities (specifically SecureDrop) in order to minimize and comparmentalize SecureDrop/Corporate/Personal accounts and data in the event of a compromise (MITIG120). Automated test for mitigation: No.
