General Security Guidelines
Network-based Vulnerability Mitigations for Embedded Products
- Utilize proper network infrastructure controls, such as firewalls, to help ensure that .NET Remoting from unauthorized sources are blocked.
- Ensure that software-based firewalls are running with current rule sets and enforced on individual systems.
- Consider implementing network security protocols for software systems, such as IPSec. Documentation is available in QA46277 - Deploying FactoryTalk Software with IPsec, outlining guidelines for implementing IPSec with FactoryTalk applications.
Software/PC-based Mitigation Strategies
- Use of Microsoft® AppLocker or other similar whitelisting application can help mitigate risk. Information on using AppLocker with Rockwell Automation products is available in QA17329 - Using Rockwell Automation Software Products with AppLocker.
- Ensure that the least-privilege user principle is followed, and user/service account access to shared resources (such as a database) is only granted with a minimum number of rights as needed.
- Use trusted software, software patches antivirus/antimalware programs and interact only with trusted websites and attachments.
- Minimize network exposure for all control system devices and/or systems and ensure that they are not accessible from the Internet. For further information about the risks of unprotected Internet accessible control systems, please see PN715 - Advisory on web search tools that identify ICS devices and systems connected to the Internet.
- Locate control system networks and devices behind firewalls and isolate them from the business network.
- When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing that VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize that VPN is only as secure as the connected devices.
