Cryptographic protocols securing communications over networks, enabling HTTPS and encrypted connections.
SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) are cryptographic protocols encrypting communications over networks. TLS secures HTTPS web traffic, email transmission, VPN connections, and many other communications. TLS ensures confidentiality (encryption), integrity (tampering detection), and authentication (verifying server identity through certificates). TLS 1.2 and 1.3 are current standards; older versions have known vulnerabilities.
Why It Matters
The DSC Perspective:
TLS protects data in transit. Ensure services use TLS 1.2 or 1.3, and disable older versions. Proper certificate management is essential—expired or misconfigured certificates break secure connections.
