# ADR 011 - TLS communication ## Date - Mar/06/2026 - First documentation ## Status - Accepted ## Context - To make administrational policy simple - Set the principle of TLS communication boundry ## Considerations ### Apply mTLS - implementing mTLS needs both client certificate and server certificate - Managing a number of certificates makes a huge operational burden (expiry date, revocation, etc ..) ## Decisions - Set TLS for all communication except 'lo' interface - When it is possible to activate TLS, apply it even in 'lo' interface ## Consequences - The policy is set simple - The overhead is increased little - Exclude the exceptions on operation (For the administrator)
