One of the biggest challenges for an industrial OT/ICS security professional is figuring out if their organization is vulnerable to the latest announced strain of ransomware. Continue readingĪ SCADAfence New Feature report “Could we be next?” Therefore adhering to OT security best practices, and deploying the most advanced OT security tools is critical for the protection, visibility, and control of OT environments.
But due to the increasing connectivity between the OT, IT and other networks, this is no longer true. In the past, operators trusted network segmentation, isolation, or air-gapping as an effective security measure. These new technologies increase the connectivity and the complexity of operational environments, and as a result, their exposure to potential OT cyber attacks or damage caused by human error increases significantly. In order to remain competitive in their industries, organizations are adopting these beneficial technologies to optimize their operations and significantly cut operational costs. Modern operational technology (OT) networks are evolving due to developments such as the rise Industrial Internet of Things (IIoT), Industry 4.0, smart grid and more. Why Do You Need Operational Network Security? This blog will explain what OpenSSL is used for, the commotion caused by the announcement this week, what it means for your OT network’s cyber security, and offer SCADAfence’s analysts advice for protecting your network from the vulnerabilities. Despite the lowered rating, and while the issue is turning out not to be the crisis that many experts had feared, this is still considered a potentially major security issue and it is important to understand it and take remedial action where necessary. However, after a few tense days of speculation, OpenSSL downgraded the vulnerability rating to “High” before publicly releasing details of the security flaw and the patch on November 1, 2022.
The original announcement on October 25th was met with a cyclone of reaction and commentary from security experts. The cyber security community was deeply engrossed this week in the news that OpenSSL, the organization responsible for the software package that encrypts and secures communications across much of the internet, was about to release a patch for a newly discovered “Critical” vulnerability.
