ICS vulnerability disclosures have grown by 110% since 2018, which Claroty said suggests more types of operational technologies are coming online and presenting soft targets.
Operational technology company Claroty makes a big claim about the future of OT and industrial control systems security: Based on data collected over the past few years, the distinction between OT/ICS and the rest of enterprise tech is beginning to fade in earnest, and new security headaches have appeared in their place.
Claroty states is case in its ICS Risk and Vulnerability report for the second half of 2021 (find the first half here), which found among other things that there has been a 110% year-over-year increase in the number of ICS vulnerabilities disclosed since 2018, and that non-OT products made up 34% of ICS vulnerabilities reported in 2021.

CISA has released a draft version of Applying Zero Trust Principles to Enterprise Mobility for public comment. The paper guides federal agencies as they evolve and operationalize cybersecurity programs and capabilities, including cybersecurity for mobility. The public comment period will close April 18, 2022.
Executive Order 14028: Improving the Nation’s Cybersecurity, issued May 12, 2021, requires Federal Civilian Executive Branch departments and agencies to adopt Zero Trust (ZT) architectures to protect the government’s information resources, of which federal mobility is an integral part. The guidance highlights the need for special consideration for mobile devices and associated enterprise security management capabilities due to their technological evolution and ubiquitous use.
CISA encourages interested parties to review Applying Zero Trust Principles to Enterprise Mobility and provide comment. See CISA Blog: Maturing Enterprise Mobility Towards Zero Trust Architectures for more information.
NextGov reports: Chairman Sen. Mark Warner, D-Va, gives an opening statement as FireEye CEO Kevin Mandia, SolarWinds CEO Sudhakar Ramakrishna and Microsoft President Brad Smith testify at a Senate Intelligence Committee hearing on Capitol Hill on February 23, 2021.
“Russia is expected to increase its cyber attacks as it continues a military assault on Ukraine, and one lawmaker warns that the U.S. should be prepared for future high level digital attacks.”
Speaking live to The Washington Post on Monday, Senator Mark Warner, D-Va. spoke about Russia’s cyber attacks on Ukraine’s networks and the spread of disinformation as part of the country’s offensive strategy.
“Do I expect Russia to up its game on cyber? Absolutely,” Warner said. “I do think we need to be prepared for high level––his A-Team––attacks against the West whether they start with nations in NATO [North Atlantic Treaty Organization] that have weaker cyber controls or whether they go straight against the United States, Britain, France, Germany.”
Warner hypothesized that Russian President Vladimir Putin did not prioritize launching cyberattacks against Ukraine’s infrastructure, and that the U.S. and other NATO allies should brace for major cyber hacks.
“When a top tier nation uses their top talent to attack in the cyber domain, chances are we will not be 100% effective at keeping the adversary out,” he said. Warner praised Cybersecurity and Infrastructure Security Agency Director Jen Easterly for strengthening protocols and being alert against cyberattacks and ransomware.”
“I think we will probably see that in the coming days and weeks as Putin tries to lash out against these crippling level of sanctions we put on him,” Warner added.
