What is TLS/SSL in Cybersecurity?
Transport Layer Security (successor to SSL) encrypts communication between clients and servers. TLS uses a handshake process to negotiate encryption algorithms, exchange keys, and verify server identity through certificates. TLS 1.3 is the current standard, removing weak ciphers from earlier versions.
Why TLS/SSL Matters for Your Cybersecurity Career
Misconfured TLS is a frequent finding in penetration tests. Expired certificates, weak cipher suites, and protocol downgrades create real attack surfaces. Security engineers configure and monitor TLS across their organization. Understanding TLS is also foundational for cryptography-related certification exams.
