A Message from Rockwell Automation. Dear Readers, We recognize these are trying times for Critical Infrastructure providers. Amid relentless cyberattacks, complex digital transformation initiatives, and a seemingly unstoppable pandemic, many organizations are grappling with securing operational technology (OT) systems. OT security has become increasingly important as threat actors have proved they can and will breach IT systems as a stepping stone to infiltrating OT and industrial control systems (ICS). This type of breach, as you’ll see, can take down IT systems and Critical Infrastructure, too. If there’s one specific threat that worries business executives, it’s the global spike in ransomware attacks. As tensions rise following Russia’s invasion of Ukraine, for example, the Cybersecurity and Infrastructure Security Agency (CISA) has warned U.S. state and local governments, aviation and energy sector networks of an increased risk of ransomware attacks from Russia.
