Discussion:
Organizations authenticate individuals and devices to help protect wireless access to the system. Special attention is given to the wide variety of devices that are part of the Internet of Things with potential wireless access to organizational systems. See [NIST CRYPTO].
Upon assessment, assessors must determine if-
3.1.17[a] wireless access to the system is protected using authentication.
3.1.17[b] wireless access to the system is protected using encryption.
Assessors are instructed to-
Examine: [SELECT FROM: Access control policy; system design documentation; procedures addressing wireless implementation and usage (including restrictions); system security plan; system configuration settings and associated documentation; system audit logs and records; other relevant documents or records].
Interview: [SELECT FROM: System or network administrators; personnel with information security responsibilities; system developers].
Test: [SELECT FROM: Mechanisms implementing wireless access protections to the system].
