Why Havex Is a Game-Changing Threat to Industrial Control Systems – Part 2
Summary: In part 2 of a two-part Unit 42 blog series, Palo Alto Networks describes how operators can mitigate Havex exposure in SCADA and ICS environments, noting that most operators still rely only on legacy stateful inspection firewalls plus IPS/AV add-ons. The post details the platform's App-ID, User-ID, and Content-ID technologies, which identify ICS protocols such as OPC, DNP3, Modbus, BACnet, and OSIsoft PI and process packets in a single pass, and cites Wildfire sandboxing with protections in as little as 30 minutes.
What's compelling: The post states that most OT operators have only port-level visibility and known-threat blocking, which leaves them without protocol/application layer visibility or zero-day detection against a threat like Havex. It also notes that segmentation and access control depend on IEC 62443 practices that many operators have not yet put in place.
