Cybersecurity Leaders Launch Operational Technology Cybersecurity Coalition
Today, a diverse group of cybersecurity leaders joined together to launch the Operational Technology Cybersecurity Coalition. Founding members include Claroty, Forescout, Honeywell, Nozomi Networks, and Tenable, each with decades of experience in building, protecting, and defending our nation’s industrial control systems and critical infrastructure assets.
The OT Cyber Coalition advocates for vendor-neutral, interoperable, and standards-based cybersecurity solutions and works collaboratively with industry and government stakeholders on how to best deploy data-sharing solutions that enhance our country’s collective defense. Its efforts support the notion that competitive solutions promote innovation and strengthen our national security.
Manufacturing: Security and Resilience Start with Visibility
Having real-time situational awareness of your OT networks, including visibility into assets, connections, communications, protocols and more, allows you to start improving cyber resiliency. The good news is that you can automate asset inventory for manufacturing facilities, eliminate blind spots, and reveal assets that might have previously been missed.
Once you’ve got excellent visibility, you can move onto risk reduction. This requires real-time detection of vulnerabilities, threats and anomalies at both brownfield and greenfield facilities. It includes process insights that highlight threats to reliability, such as failing equipment, unusual variable values and networking communication anomalies.
Critical Log4Shell (Apache Log4j) Zero-Day Attack Analysis
This is a critical vulnerability that is affecting a wide range of systems and users. It is very easy to exploit so many attackers are testing out the new vulnerability very rapidly. Users should upgrade quickly their Apache logging utility to Log4j 2.16.0 or alternatively apply one of the workarounds provided by the vendor. Nozomi Networks customers will be able to leverage our Threat Intelligence service for the latest countermeasures to this exploit.
The Long-range Disruption of Industrial IoT LoRaWAN Networks
This blog post from the Nozomi Networks Labs team investigates attacks against a low-power radio frequency WAN technology that is widely used in industrial IoT networks. Our research focused on the viability of discovering the transmission frequency of the IoT network, and jamming the signal to disrupt network communication. Although there are some practical limitations to the attack scenario we investigated, we clearly determined that there are potential attack vectors that should be considered as technology matures.
