ICS-CERT recommends that users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Specifically, users should:
- Minimize network exposure for all control system devices. Control system devices should not directly face the Internet.a
- Locate control system networks and devices behind firewalls, and isolate them from the business network.
- If remote access is required, employ secure methods such as Virtual Private Networks (VPNs).
ICS-CERT reminds organizations to perform proper impact analysis and risk assessment prior to taking defensive measures.
The Control System Security Program also provides a recommended practices section for control systems on the US-CERT website. Several recommended practices are available for reading or download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Organizations that observe any suspected malicious activity should follow their established internal procedures and report their findings to ICS-CERT for tracking and correlation against other incidents.
