SSL/TLS

What is SSL/TLS?

SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) encrypt data transmitted between clients and servers. TLS secures HTTPS connections, email, VPNs, and many other protocols. A TLS handshake involves certificate verification, key exchange, and cipher suite negotiation. Security issues include expired certificates, weak cipher suites, outdated protocol versions (TLS 1.0/1.1), self-signed certificates, and certificate chain problems. Regular SSL/TLS scanning ensures encrypted connections are properly configured.
