General Security Guidelines
- Run all software as User, not as an Administrator, to minimize the impact of malicious code on the infected system.
- Use of Microsoft® AppLocker application or another similar whitelisting application can help mitigate risk. Information on using AppLocker with Rockwell Automation products is available at Knowledgebase Article ID QA17329 .
- Ensure that the least-privileged user principle is followed, and user/service account access to shared resources (such as a database) is only granted with a minimum amount of rights as needed.
- Use trusted software, software patches, antivirus/antimalware programs and interact only with trusted web sites and attachments.
