Firewall Logging for OT Security: What to Log, What to Watch, and Why | OT Security Module 5.8

A firewall without logging is just a barrier — with logging, it becomes a detection tool that can tell you an attack is underway before it becomes an incident. This final Module 5 lesson covers what firewall logs record, which patterns in the logs are worth investigating (port scans, unexpected outbound OT traffic, off-hours access), and how to manage logs practically — centralized storage, 90-day minimum retention, and SIEM integration. By the end of this video, you'll know what to look for in your firewall logs and how to build a review process that's actually sustainable. 🕐 Chapters: 0:00 – Why logging transforms a firewall into a detection tool 1:30 – High-value log patterns to monitor 3:30 – Log management: centralization and retention 4:45 – SIEM integration and what it means for OT teams 5:30 – Building a practical log review process 6:05 – Module 5 wrap-up and what's coming next (network assessment tools) Part of Module 5: Firewalls Full course playlist: [link] If this was useful, subscribe for more content like this. #OTSecurity #IndustrialCybersecurity #ICS #SCADA #FirewallLogging #SIEM
