User Identification, Authentication, and Re-authentication

Level 1 (Mandatory April 2026)
IA — Identification and Authentication

Control Description

Uniquely identify and authenticate system users, and re-authenticate when required.

Assessment Objective

Verify that users are uniquely identified, authenticated, processes are associated with authenticated users, and re-authentication occurs when required.

Assessment Scope

This control includes 4 determination statements that assessors evaluate during a CPCSC assessment. Each determination must be satisfied with documented evidence to demonstrate control effectiveness.

CPCSC Context

This is one of the 13 controls required for CPCSC Level 1 self-assessment, mandatory from April 2026 for all Department of National Defence (DND) contract awards. Level 1 is a self-attestation — no third-party assessor is required.
