The Benefits of Secure Remote Access to Industrial Process Data

It can be tricky in this era of increasing cross-connectivity of anything and everything, from a lowly household appliance to IT/OT hybrid systems applying predictive analytics to an industrial process, to balance connectivity everywhere and the required security to mitigate cyber threats.  In the past, remote access to industrial process data often required network access to the actual HMI or SCADA system on the process network.  But why do you need network access to your SCADA system, when all you really need is just to access the data?

In this blog post, we'll discuss a few of the key benefits to having remote access to your industrial process data, which can be essential to making timely business decisions and discuss a flexible solution for enabling remote access without exposing your industrial process network to outside threats, including how to sign up for a free account for a limited time.

In the first post of our ongoing Exploring OPC UA blog series, we covered the three functions that OPC UA Certificates (also known as Application Certificates) serve in the context of OPC UA security.

In this second post, we'll take a look at what happens to messages after you have trusted the application certificates and have enabled security on the OPC UA endpoint. Specifically, what does Sign&Encrypt mean on an endpoint and how can we be sure that the data is truly secure.

Exploring OPC UA - OPC UA Certificate Basics

The use of certificates in cryptographic applications and online communication protocols is nothing new and can practically be traced all the way back to the 1970's when the "framework" for public key encryption (more on this in a future blog) came into being. With the (now-not-so-recent) Industry 4.0 movement coming out of Europe, and the design and operation changes brought about by the IIoT phenomenon, we are seeing more and more systems – that have traditionally been air-gapped and kept offline – being brought online to take advantage of the digital revolution in which we find ourselves.

Despite how you feel about this (r)evolution there are several exciting changes that are being brought about, including the one I want to discuss is the increased adoption of OPC Unified Architecture (OPC UA) in automation systems.

In this first post in our ongoing Exploring OPC UA blog series, we will look at what OPC UA Certificates are and what they provide and subsequent posts will further explore how they are used in OPC UA, how they fit into the security ‘stack’ of OPC UA and will then look at how OPC UA Certificates are utilized and managed in several Software Toolbox applications. First thing’s first however; what are OPC UA Certificates and what are they used for?

Break Down Your Obstacles to OPC Standard Interoperability

6 min read

By Win Worrall on Aug 24, 2017 2:00:00 PM


OPC has been around as an industry standard since 1996.  If you’ve been working in the space very long, you have probably heard all the different acronyms thrown around.  If you’re new, well there are different specifications in the OPC software interoperability standards that are used to meet different information integration needs.

In this first post of our “I Can Do That?” blog series, I’ll explore examples of the connections between different OPC standards we hear about from users, ways to address them using OPC Gateway software, and use cases highlighting solutions we’ve seen other users implement successfully.
