|Read access violation||Remote||Denial of Service|
Please report any issues affecting control systems in critical infrastructure environments to ICS-CERT.
ICS-CERT released a follow-up advisory, ICSA-12-088-01 Rockwell Automation Rockwell Automation FactoryTalk RNADiagReceiver, to the ICS-CERT web page on March 28, 2012.
ICS-CERT is currently coordinating with the vendor and security researcher to identify mitigations.
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), recognizing that VPN is only as secure as the connected devices.
ICS-CERT reminds organizations to perform proper impact analysis and risk assessment prior to taking defensive measures.
The Control Systems Security Program (CSSP) 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.
