Some more things happening on the OPC front the last little while.  I see Tom Burke revamped his blog.  It’s got a new RSS feed, more links to information on OPC UA and all the past postings from the previous blog.

The third installment of the OPC Security Whitepaper Series written by Byres Research, Digital Bond and BCIT.    I’ve posted before on Parts One and Two.   This final paper presents guidelines for hardening OPC hosts from a security point of view.    It seems to me the two biggest hurdles to getting systems more secure is: 1) educating users on what can be done and, 2) convincing them to do it.  Of course that is easier said than done.

Along with the very thorough hardening guidelines presented in the whitepaper, users can also look at different architectures or how product like OPC Tunneller fit into their overall security setup.

And last but not least, the MatrikonOPC Users Group seminar will be held in Houston, Texas on October 24th.   As with previous OPC User’s Groups the focus is on how OPC can be used to solve many of the common integration problems user’s face.   It’s also a chance for OPC users to mingle and find out how others are using OPC.   The format has changed a bit this year.  Rather than one big multi-day event, there it will be an intimate, one day, focused seminar held in various locations.  The means the seminars can be tailored to local wants and needs as well as saves participants traveling costs.
