TLS
Software Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: Transport Layer Security (TLS) is a cryptographic protocol that provides secure communication over a network. It ensures confidentiality, integrity, and authentication between client and server applications.
Example in context
“All internal microservices must communicate over TLS 1.3 to prevent eavesdropping and data tampering in transit.”
“Tüm dahili mikro hizmetler, dinleme ve veri kurcalamayı önlemek için TLS 1.3 üzerinden iletişim kurmalıdır.”
Where engineers use it
Engineers configure TLS certificates on servers and reverse proxies. They monitor cipher strength, handle certificate renewals, and enforce secure handshake parameters in network policies.
Synonyms: SSL/TLS, Transport Layer Security
Antonyms: plaintext
Practice: can you use “TLS” at work?
A security audit reveals that some services still accept TLS 1.0 connections. Your task is to update cloud load balancer settings. What protocol changes do you propose?
