PL-4 Rules of Behavior

High-Level Description

Family: Planning (PL) Framework: NIST SP 800-53 Rev 5

Rules of behavior represent a type of access agreement for organizational users. Other types of access agreements include nondisclosure agreements, conflict-of-interest agreements, and acceptable use agreements (see PS-6 ). Organizations consider rules of behavior based on individual user roles and responsibilities and differentiate between rules that apply to privileged users and rules that apply to general users. Establishing rules of behavior for some types of non-organizational users, including individuals who receive information from federal systems, is often not feasible given the large number of such users and the limited nature of their interactions with the systems. Rules of behavior for organizational and non-organizational users can also be established in AC-8 . The related controls section provides a list of controls that are relevant to organizational rules of behavior. PL-4b , the documented acknowledgment portion of the control, may be satisfied by the literacy training and awareness and role-based training programs conducted by organizations if such training includes rules of behavior. Documented acknowledgements for rules of behavior include electronic or physical signatures and electronic agreement check boxes or radio buttons.

What to Check

• Verify PL-4 Rules of Behavior is documented in SSP
• Validate all 4 control requirements are implemented
• Confirm control is operating effectively
• Review evidence of continuous monitoring for PL-4

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for PL-4 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.
