2024 audit - SEC-01-017 WP3: Lack of Full Disk Encryption

[zenmonkeykstop]

Servers lack full disk encryption, risking data theft via physical access to hard drives.
Attackers may dump server content or recover data from damaged hardware. While
daily automatic reboots make physical access harder to exploit, using full disk encryption
can easily address the risk from hardware replacement scenarios

This is a known issue that is currently mitigated by having all source data and messages encrypted at rest. See #816 for details. We will consider further work on this.
