There is also an exciting opportunity to learn more about PI System security and baselining with the PI Security Audit Tools from Anna Perry at the upcoming UC 2017 lab, Extending the PI Security Audit Tools to Meet the Needs of Your Environment at 2:15 pm on the day 3 agenda. I've included the description below. If this topic interests you, please sign up when you register for UC 2017!
"How do you baseline the security of your PI Systems? How do you evaluate which defenses should be prioritized? These are questions every PI System administrator faces. The PI Security Audit Tools are a framework for security configuration auditing of PI System components in the form of a PowerShell module. In the first half of this lab, participants will learn how to use the existing tools to evaluate their PI System deployments and use the output to plan and prioritize improvements to their defenses. The second half of the lab will focus on the tools' extensibility. Participants will learn how to extend the PI Security Audit Tools existing libraries to include validation checks specific to their organization's needs and how to implement their own libraries with the tool."
