This lesson covers the misconfigurations that appear most frequently in OT security assessments and post-incident analysis: allow-any rules left from troubleshooting, unrestricted outbound traffic from OT devices, always-on vendor VPN connections, rules with no expiration, wrong-interface rule assignments, and missing logging.
