IA-3(1) Cryptographic Bidirectional Authentication
Control enhancement of IA-3 Device Identification and Authentication
Control
Authenticate [Assignment: devices and/or types of devices] before establishing [Assignment: Selection (one-or-more): local | remote | network] connection using bidirectional authentication that is cryptographically based.
Discussion
A local connection is a connection with a device that communicates without the use of a network. A network connection is a connection with a device that communicates through a network. A remote connection is a connection with a device that communicates through an external network. Bidirectional authentication provides stronger protection to validate the identity of other devices for connections that are of greater risk.
