- TLS Basics
- TLS secures network communication between nodes through cryptographic protocol
- Client and server negotiate TLS version during initialization process
- TLS 1.0 and 1.1 are deprecated, TLS 1.3 is recommended
- Checking Methods
- OpenSSL s_client command allows specifying TLS version options
- Nmap's ssl-enum-ciphers script enumerates TLS versions and ciphers
- ssllabs.com website provides GUI-based TLS configuration analysis
- Implementation
- OpenSSL s_client requires installation via package manager
- Nmap installation needed for ssl-enum-ciphers script
- ssllabs.com requires hostname input for analysis
- Hosts support different TLS versions based on configuration
