cyberstrikeus AT-3(1) Environmental Controls
Enhancement of: AT-3
High-Level Description
Family: Awareness and Training (AT) Framework: NIST SP 800-53 Rev 5
Environmental controls include fire suppression and detection devices or systems, sprinkler systems, handheld fire extinguishers, fixed fire hoses, smoke detectors, temperature or humidity, heating, ventilation, air conditioning, and power within the facility.
What to Check
- Verify AT-3(1) Environmental Controls is documented in SSP
- Confirm control is operating effectively
- Review evidence of continuous monitoring for AT-3(1)
- Verify enhancement builds upon base control AT-3
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for AT-3(1) 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.
