5 monitoring strategies for cyber security in OT

There is no doubt that the most secure OT environment is an isolated network, which does not necessarily need special security measures. However, with the convergence of IT and OT, many OT networks now need to be integrated with external systems and networks. And for these OT networks, it is crucial that comprehensive cyber security strategies are in place. As in IT, monitoring infrastructure, devices, and systems forms a vital part of such strategies. Here are five ways that monitoring can form part of an OT cyber security strategy.

How to integrate Advantech gateways with PRTG using Node-RED

As is well known, a gateway can establish the connection between industrial machines, control units or individual sections of production lines and classic IT networks. In doing so, they enable communication between systems that are not necessarily compatible with each other and can thus also integrate Operational Technology (OT) data into an IT monitoring concept. Due to increasing digitalization, this aspect is becoming more and more interesting for many companies.

Several options to monitor your backup with PRTG

As an IT admin, you know what it feels like to live with the constant fear of data loss. You think that you have a reliable backup solution in place, so making regular backups should be working fine – just to realize that an important backup failed, and a lot of even more important data has been lost, be it your own company data or your customer’s data.

Get alerted on data center outages with Microsoft Teams

Visualizing your IT and OT environment with PRTG

Holistic monitoring for industrial IT is a topic that we have covered on this blog many times before. We even put together a white paper about it. Essentially, holistic monitoring incorporates elements from IT and OT into one tool. One of the greatest advantages of this approach is that you can develop dashboards that deliver an overview of your entire industrial IT infrastructure. To demonstrate this, I will be writing a series of blog posts examining specific examples of dashboards for industrial environments that were created with Paessler PRTG monitoring software. 

The magic of building individual custom network maps with PRTG

Are there good and reliable tools out there that allow you to create professional network diagrams? Yes, there are! And some are even free of charge.

We'd like to tell you about it, pointing out the important features of a solution that creates handy and useful overviews of your network.

Ensure that the right person or team gets the right notifications

Reliable notification of a malfunction or even a system failure in a data center is one of the most important tasks of a monitoring application. The notification should be configurable in different ways depending on the requirements. PRTG provides a number of notification options such as email, push, SMS, etc. This article, however, is not about the different notification options, but rather about how you can ensure that individual colleagues or teams in your IT department are provided with the correct and appropriate information.

Monitoring Industrial IT: defining and getting the data you need

Data is at the core of monitoring any environment. And in an industrial IT environment, this data exists in various devices, systems and sensors in the OT, IIoT and IT areas. And for a sound holistic monitoring concept, there are two aspects you need to consider: what data you need, and how you are going to get the data. Let's take a look at both of these points. 

Prevent expired OPC UA certificates halting your production line

In recent times, OPC UA has become widely-adopted in industrial IT environments. In short, it provides a common communication standard that allows elements from various parts of the industrial infrastructure to communicate with one another. One of the most basic aspects of OPC UA are the OPC UA certificates, which provide a level of security between communicating components. But what happens when these certificates expire? And how can you monitor them so that you always know what their status is?
