Security+ ยท 3.0 Security Architecture
TLS (Transport Layer Security)
The successor to SSL. an encryption protocol that provides confidentiality, integrity, and authentication for network connections. HTTPS = HTTP over TLS. Uses X.509 certificates for server (and optionally client) authentication.
How this shows up at NCAE
WWW SSL check failures (cert expired, CERTIFICATE_VERIFY_FAILED, record layer failure) all trace back to TLS fundamentals. The `openssl req` cert-regeneration command is the fix for most.
