OPC Level 2

Securing OPC Systems.

Certified OPC Level 2Students apply security measures that comply with IT policies, industrial best practices, and government (SOX) regulations for cybersecurity. Students learn how to configure the Windows Firewall and the minimal required exceptions for OPC communication. They also learn the minimal set of users and groups that are necessary to include in the System Access Control Lists. This enables integrators to step away from their OPC installation with the confidence that it is properly secure.

Course Length: 12 hours



DCOM Configuration: The class begins with a series of hands-on exercises designed to put DCOM theory into practice. Students diagnose OPC and DCOM problems, and work to repair them.

Data Execution Prevention: Students learn how to diagnose OPC problems that are caused by misbehaving software. Once the problem is diagnosed, students determine whether or not they should get the software fixed, or if they should configure Windows around the misbehaving software.

OPC and the Firewall: Students configure the Windows firewall to enable OPC communication. This includes both port and protocol exceptions. The class discusses the difference between the Windows firewall and external firewalls.

Access Control Lists: Students configure their OPC applications to permit only the absolute minimum set of Access Control Entries to ensure maximum security. They then allow only the necessary people to gain access. This ensures people are able to have secure OPC implementations that are able to resist access from non-authorized personnel.

Demilitarized Zone (DMZ): Students learn how a DMZ helps satisfy federal, industrial, and company security requirements. The class discusses the DMZ’s impact on OPC communication, and the necessary components to ensure a secure and robust communication platform.

OPCTI provides hands-on training and as such, each student receives their own dedicated computer for the duration of the training so they can complete all the exercises on their own. (Students can also bring their own laptops.) OPCTI provides all the necessary software licenses. The software used is from various vendors to expose students to various solutions and ensure a vendor-neutral message. At the end of the course, participants receive a demo copy of all the software so they can review the exercises at a later date and/or try out the software at their workplace.
