- Mar/06/2026
    - First documentation
    
## Status

- Accepted

## Context

- To make administrational policy simple
- Set the principle of TLS communication boundry

- Set TLS for all communication except 'lo' interface
- When it is possible to activate TLS, apply it even in 'lo' interface

- The policy is set simple
- The overhead is increased little
- Exclude the exceptions on operation \(For the administrator\)
