How does EchelonGraph detect NIST 800-53 PE-3 violations?

EchelonGraph automatically detects NIST 800-53 PE-3 violations using scanner rule NIST-PE-003. The scanner checks cloud infrastructure configurations in real-time and flags non-compliant resources.

What audit questions are asked for NIST 800-53 PE-3?

Show the cloud-provider SOC 2 attestation covering data-center physical security. What badge / visitor controls protect your office? What is the MDM screen-lock policy? When was the last physical-security walkthrough?

🏛️NIST 800-53 PE-3Rule: NIST-PE-003medium

Physical Access Control

Description

Enforce physical access authorizations for entry into facilities containing the system.

⚠️ Risk Impact

Physical access defeats most logical controls. An unauthorized person in a server room (or in the office with access to unlocked workstations) can extract credentials and plant persistent access invisible to every IAM/EDR control.

🔍 How EchelonGraph Detects This

NIST-PE-003Automated scanner rule

EchelonGraph's Tier 1 Cloud Scanner automatically checks for this condition across all connected cloud accounts. Violations are flagged as medium-severity findings with remediation guidance.

🔧 Remediation

For cloud-only orgs: inherit data center physical security from AWS/GCP/Azure SOC 2 reports. For offices: badge access, visitor management, MDM-enforced workstation lock, clear-desk policy.

💀 Real-World Attack Scenario

A contractor tailgated into an office after hours, plugged in a USB Rubber Ducky on an unlocked workstation, and extracted cached AWS credentials. The credentials were used for cryptocurrency mining for 2 weeks before AWS billing flagged anomalies. Physical access bypassed every other control.

💰 Cost of Non-Compliance

Physical-access breach: avg $4.2M (IBM 2024). HIPAA §164.310(a) violations: $100K-$1.5M.

⚡ Common Pitfalls

⛔Cloud-only orgs ignoring office physical controls
⛔Tailgating culture defeats badge controls
⛔MDM screen-lock not enforced or set too long

📈 Business Value

Documented physical controls close a category of attack that bypasses every digital investment. Low effort; high audit defensibility.
