What are the different options we have. We would like to keep our process control network isolated, if possible. I suppose we have not bought into the Industrial Internet of Things (IIoT) idea / Kool-aid.
There are two main methods for deploying Windows Updates in a Process Control Network, WSUS (using upstream and downstream WSUS servers) or Offline Physical Media Deployment.
There are major considerations to take into account when deciding the best method for delivering updates on your PCN.
-Which applications have vendor specified approved Windows Update lists and update media?
-Do you have a secure method to connect an upstream WSUS server on the Corporate Network to a downstream WSUS server on the PIN?
-What method will you use to test updates stability?
We specialize in implementing and designing Windows Update methods for Process Control Networks. Please contact us at Jason.Baum@processwise.com
