Data Encryption in Transit

Encryption

Data in Transit TLS (Transport Layer Security) HTTPS SSL (Secure Sockets Layer)

Transport-layer confidentiality and integrity.

Definition

Data encryption in transit typically refers to transport security (e.g., TLS) that encrypts application data and provides integrity protection during transmission between endpoints.

In plain English Transport-layer confidentiality and integrity.

Why this matters

Why it matters: It mitigates passive eavesdropping and active MITM manipulation on untrusted networks.

Example

Example: TLS 1.3 with modern cipher suites for HTTPS connections.
