In June 2021, in response to a security vulnerability, Microsoft released a Windows update (KB KB5004442) to harden the DCOM component of Windows. Organizations should be aware that many industrial control system applications utilize DCOM protocols. This update can impact the ability of networked devices to communicate, resulting in effects such as the inability to use HMI or SCADA software, or loss of historical tag data.
Some impacted applications include: RSLogix 5/500/5000, RSLinx Classic, FactoryTalk applications, ThinManager, and KEPServer Enterprise.
Champion recommends that organizations review their installed software for use of DCOM and the potential impact of this update. Most ICS software vendors have published information on their affected software as well as possible mitigations for any impacts from applying these updates. For actively maintained software, vendors are working to deliver patches for their software to work with the update. Until these patches are available, it will be necessary to either postpone installation of the Windows updates or apply mitigations to disable the new DCOM hardening features. Be aware, however, that if the Windows updates are installed, it will not be possible to disable the DCOM hardening features after March 14, 2023.
Champion can work with you to help you decide which Windows updates are appropriate to install and deliver those updates to your critical ICS systems. Champion can also provide recommendations on working with software that may no longer be supported by the vendor or assist you with planning upgrade paths. Finally, when things do break, Champion can assist with recovery. We will continue to monitor the situation and be prepared to keep our clients informed.

Apache Log4j is one of the most popular web server logging utilities used in thousands of software applications. The Apache Log4j logging service (v 2.14.1 and below) vulnerability can allow malicious users to remotely execute code which can compromise the integrity of the system.
Any software with a web-based client or configuration component may be affected if it uses the Apache Log4j library. Some of these valuable assets can include Virtualization Hypervisor servers, accounting software packages, and software that runs on firewalls protecting your environments.
If any active machines at your facility have vulnerable software with no readily-available fix, we recommend turning the off the machine(s) until a fix has been found. This is recommended for non-business critical assets only.
Champion is reaching out to our OT software partners and vendors to compile a list of known affected products, along with remediation strategies. We can also assist in verifying that your OT environments are safe.

Anytime a new conduit to an ICS network is created – especially one which transits the internet – there is inevitable trepidation about the potential security risks it might create. So, when we talk about creating a tunnel from your network into the cloud, you’re going to have mental alarms going off. This article will describe how Champion keeps your network secure while providing unprecedented levels of service and support.
A security zone is created in the cloud specifically for you. Here, it serves as an extension of the Demilitarized Zone (DMZ) of your control system. The same security concepts that apply to your DMZ apply here as well.
These paths are restricted by routing and firewall rules to pass only the authorized data.
No windows administrative connections (RDP, WMI, RPC, and other evil acronyms) can be made from outside the DMZ and cloud zones. All administrative activity happens within the cloud zone via hosted desktop sessions. These sessions are delivered using virtual desktop presentation technologies so that only the video stream leaves, and only keyboard and mouse commands enter. No proprietary data or external threats can be transferred via either cloud path.
In order to connect your site to the cloud, a tunnel must be created. This tunnel is built using the best available VPN protocols . Like most tunnels, its job is to keep the good things in and the bad things out.
It’s often stated that if you can’t see it, you can’t secure it. To ensure your network stays safe, it’s vital to have eyes on the traffic that’s going through it. Like a building with door sensors, motion detectors, smoke detectors, security cameras, and a remote monitoring service… Champion can be your partner in notifying you in real-time of any abnormal activity.
While opening a tunnel between your network and the cloud might sound scary, using the proper technology and partner allows your network and OT assets to be safer than ever. Not only will you be better protected from security threats, but now we can even alert you to process issues before they become big problems.
Remote support engineers can respond even quicker and without introducing you to unnecessary risks like VPN connections from untrusted computers, unmonitored persistent virtual desktop access, or cellular modems.

While everyone is familiar with the term “IT” (Information Technology), the term “OT” (Operational Technology) is far less familiar to the general public. That is not to say OT is newly emerging; quite the opposite. Over the last two decades, IT and OT have begun to converge. You’ve likely heard terms like “IIoT” (Industrial Internet of Things) or “Industry 4.0.” But there are unique differences that set OT apart from IT:
Since production is the livelihood of any industrial facility, so too are the operational systems that keep them moving. Loss of production for any reason has a direct impact on a company’s bottom-line. Whether due to an outdated, unreliable platform, poor configuration, unprepared support staff, or insecure technology allowing for system breaches – many factors can affect production. Be sure to utilize an OT specialist with the experience to reach your maximum production output.
Securing proprietary information is a major concern with any corporate IT network. But cybersecurity is equally (if not more) important for a facility’s Industrial Control Systems. In past years, many have taken the “air gap” approach to securing their OT control systems – keeping any production equipment separated from Internet-connected Enterprise equipment. In theory – and in a time before flash drives and smartphones – this was enough to mitigate operational risks. But, as consumer technologies emerged, so too did many large-scale security breaches affecting Industrial Control Systems.
Air gapped systems that were not physically connected to the Internet would run on outdated security patches because they were seemingly “secure.” With the advent of devices like flash drives and smartphones, however, control systems around the globe became vulnerable. Cyber-attacks could now halt production, disable critical safety systems, or result in catastrophic loss simply by altering production readings.
Having a team of Globally Certified Cybersecurity Experts at your fingertips is now vital for any industrial environment.
While the fundamental principles of IT networks are shared with OT networks, Industrial Control Systems require a much more specialized set of skills to implement and maintain. For starters, the very environment of each are vastly different. IT networks are often climate-controlled in office environments, whereas OT networks can be exposed to extreme elements and process environments.
More importantly, what sets OT professionals apart is their knowledge of how to implement specific industry processes, using a range of industrial controls across multiple platforms. Lastly, they must use this knowledge to make everything communicate in an efficient, reliable, and intuitive manner.
With vast experience across numerous industries, platforms and technologies, Champion’s OT professionals deliver on this expertise.
The natural lifecycle of IT versus OT lends itself to completely different budget approaches. While IT environments typically change every 12-18 months, OT environments can last 10-15 years or more – if they are properly designed and maintained.
The key to enabling Industrial Control Systems for the extended durations is proper maintenance and support. In addition to cybersecurity risk mitigation, including budgetary funds for preventive maintenance and support is essential in any OT environment. As a system ages, it is key to provide regular security patches, scheduled backups, and a supply of spare parts to achieve the greatest production output.
Champion’s knowledge of these items, paired with our 24UP Support Solutions, allow customers to tailor specific needs into one easily-predictable budgetary plan.
Another unique difference between IT and OT is the types of compliance each must meet. Industrial Control processes are typically subject to far more scrutiny due to their ability to impact more than a corporate entity; if improperly maintained, a process can harm employees, communities, or the environment. For this reason, it is imperative that OT systems function correctly and reliably.
OT networks continuously monitor process stages, operating temperatures and pressures, environmental emissions, leaks, or any other number of factors associated with the facility. Having reliable systems in place not only raise overall safety. They allow companies to provide real-time or historic reporting to compliance agencies, such as the EPA, DEQ, FDA, or OSHA.
Champion engineers and professionals hold the experience necessary to implement the reliable OT systems our customers demand.

“Security by isolation” or air-gapping previously worked in Operational Technology (OT) environments when OT and IT were completely isolated from one another. Many older systems based on PLC’s and SCADA were built without cybersecurity in mind. OT and IT are now converging as organizations embrace the digital transformation, and security experts are now declaring the air gap dead as security by isolation is not a long-term solution for protecting OT assets.
Air Gapping an OT system has very limited value in today’s constant technological advances. It can no longer be used as a sole security solution in the long term for three reasons:
While air-gapped OT systems can minimize risks, organizations are not able to benefit from the highly valuable data these systems generate. Data analyzed in real time can provide business intelligence to cut costs, reduce downtime, and improve efficiency. These opportunity costs outweigh air-gapping as a viable cyber security measure.
Maintaining air-gapped OT systems are more expensive and difficult because the engineering tools of a connected system cannot be used to perform routine maintenance or troubleshoot problems. It also limits the system from secure remote support by technical experts. Without remote access, facilities experience higher support costs and increased downtime. The reality is that even a properly air-gapped system is not completely protected; Every system is a potential breach target, and even air-gapped systems can be infiltrated. Organizations must engage in active monitoring and security measures to mitigate the risks.
Air Gaps can be physically breached by a third-party networked laptop, USB drive, removable media, smartphone, or other devices. Allowing OT systems to connect with these devices creates vulnerabilities that air gapping cannot protect against. Air gapping makes it difficult for users to move back and forth between the air-gapped device and network-connected devices. For ease of use, an individual may use an unsecure USB drive to transfer data which could compromise an air-gapped system.
OT infrastructure is only as secure as the user operating the devices. An openly accessible USB port can serve as an entry route for malware. Smartphones provide another convenient route to cross air gaps when switched to Wi-Fi hotspot mode. The Wi-Fi hotspots can also be used as an entry point by hackers or those with ill intentions.
FUN FACT:
Source: Kapersky
90+% of randomly found USB drives are picked up by the casual person and more than half are plugged into a PC.
OT cyber-attacks are more dangerous in nature. An OT attack can pose risks to operational and safety systems, employees, plant, and environment. Because the outcome of an OT cyber-attack is more catastrophic, it is essential that organizations prioritize cybersecurity. While air gapping provides some security, it is not the best option to select in the competitive marketplace.
Air gapped control systems are also more vulnerable because they don’t receive the latest Windows security patches easily, therefore are usually neglected. As new virus threats emerge, the OT system will likely be unprotected, unlike its Enterprise counterpart.
We must accept the fact that air gapping as a security control is no longer a valid option. IT and OT will continue to converge leaving air gapping to be useless. Facilities should take advantage of the opportunities from integrated technologies to reduce costs and downtime while improving efficiency. While doing so, they must prioritize OT security to lessen the risk and still capitalize on the advantages of a connected IT and OT world.
Have you noticed in recent years, the topic of Cybersecurity has become increasingly popular?
A number of studies have found that untrained employees are the biggest threat to an organization’s network security. A study[1] by ESI ThoughtLab found that 87% of executives are aware of this fact. Consequently, companies of all industries and sizes are now putting more focus on preventing (or minimizing) attacks by investing in training for employees using Operational Technology (OT) systems including Industrial Control Systems.
The examples below[2] are common pitfalls when there are human-factor vulnerabilities:
That’s OK! Even trained employees are human. The good news is many weak links can be prevented by improving the security of your ICS network.
