Secure Communication


Classification Key : Exterior Security, Information Disclosure

Problem

The communication channel is susceptible to various attacks and it is inherently unreliable. The communication between two protected systems or a subject and a protected system is jeopardized by the unreliability of the communication channel. How can we ensure that the data being passed across public or semi-public space is secure in transit in the midst of these threats?

Solution

Ensure that mutual security policy objectives are met when there is need for two parties to communicate in the presence of threats. Create secure channel for sensitive data that obscure the data in transit. Reduce the associated overhead on the system by using ordinary communication channels for non-sensitive data.

Known Uses

Secure Socket Layer 3.0. Transport Layer Security 1.0.
