**Direct TLS**: HTTPS, LDAPS, SMTPS, IMAPS, POP3S
**SSH**: SSH (Port 22)
## Compliance Standards
- BSI TR-02102-1: Certificate requirements
- BSI TR-02102-2: TLS cipher suites and parameters
- BSI TR-02102-4: SSH key exchange, encryption, MAC and authentication methods
- IANA TLS Parameters: Cipher suites, signature schemes, supported groups
- IANA SSH Parameters: Key exchange, encryption, MAC and compression algorithms
