# Performing SCADA HMI Security Assessment
## When to Use
- When assessing the security posture of HMI systems in SCADA/DCS environments
- When evaluating web-based HMI interfaces for common web vulnerabilities
- When auditing HMI authentication, authorization, and session management
- When testing communication security between HMIs and PLCs/RTUs
- When preparing for IEC 62443 or NERC CIP compliance assessments
**Do not use** for testing HMIs in active production without a maintenance window and rollback plan, for PLC-level protocol analysis (see performing-s7comm-protocol-security-analysis), or for general web application testing on non-OT systems.
