IA-3(3) Dynamic Address Allocation
Enhancement of: IA-3
High-Level Description
Family: Identification and Authentication (IA)
Framework: NIST SP 800-53 Rev 5
The Dynamic Host Configuration Protocol (DHCP) is an example of a means by which clients can dynamically receive network address assignments.
What to Check
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for IA-3(3) implementation details. Verify the organization has documented how this control is satisfied.
Step 2: Validate Implementation
# For cloud environments, use cloud-audit-mcp tools
# For on-premises, review system configurations directly
# Example: Check if account management policies exist
grep -r "account.management\|access.control" /etc/security/ 2>/dev/null
Step 3: Test Operating Effectiveness
Verify the control is actively functioning, not just documented. Check logs, configurations, and operational evidence.

Remediation Guide
Control Statement
Where addresses are allocated dynamically, standardize dynamic address allocation lease information and the lease duration assigned to devices in accordance with [organization-defined] ; and
Audit lease information when assigned to a device.
Implementation Guidance
The Dynamic Host Configuration Protocol (DHCP) is an example of a means by which clients can dynamically receive network address assignments.
