TLS: Transport Layer Security in Cybersecurity
TLS stands for Transport Layer Security. TLS is a cryptographic protocol that encrypts data in transit between two endpoints. It replaced SSL and protects web traffic, email, and other communications.
How TLS Is Used in Cybersecurity
Cybersecurity teams enforce TLS across all public-facing services to prevent eavesdropping and man-in-the-middle attacks. SOC analysts monitor for TLS misconfigurations and expired certificates. Security engineers configure TLS policies on load balancers, APIs, and internal microservices.
