Coalition Pushes CISA for Mandatory OT Security Rules
The Operational Technology Cybersecurity Coalition is urging CISA to set mandatory security rules for operational technology used in over 8,000 federal facilities, including labs, hospitals, and ports, to protect critical systems like HVAC, power, and water. A binding directive would establish much-needed minimum security practices for federal OT systems.
Coalition Urges CISA to Mandate OT Security Standards for Agencies
The Operational Technology Cybersecurity Coalition is urging CISA to set mandatory OT security standards for federal agencies, ensuring the government practices what it preaches when it comes to cybersecurity. By doing so, agencies will have clear responsibility for OT cybersecurity and a baseline for protection.
Network Segmentation Flaws Expose Corporate Attack Surface
Flat networks are a hacker's dream, allowing breaches to spread freely to critical systems that should be off-limits - and a recent analysis of 47,700 real-world network segments reveals that device mixing is a widespread problem. The average network segment contains 54 devices from four different categories, increasing the risk of a security breach.
Senate Intel Chair Urges Treasury to Bolster OT Security with Tax Code Tweaks
The US is under attack, with recent breaches hitting community water systems in Minnesota and Iran-backed threats targeting critical infrastructure, prompting Sen. Tom Cotton to urge the Treasury Department to take action. He’s calling on Treasury Secretary Scott Bessent to use tax code tweaks to boost investment in operational technology security.
Iran-linked CyberAv3ngers targets US water systems
A coordinated cyberattack recently hit over 30 community water systems in Minnesota, prompting a swift response from state officials to ensure public health and safety. The Minnesota Department of Health is working closely with affected facilities to mitigate the impact and prevent any disruptions to drinking water supplies.
US, Australia Urge Critical Infrastructure to Isolate Vital Systems During Cyberattacks
Stay ahead of cyber threats: the US and Australia are urging critical infrastructure operators to isolate vital systems during cyberattacks to minimize damage and protect essential services. A new advisory provides practical guidance on how to plan for and execute a safe disconnection from vulnerable networks.
AI Tools Facilitate but Fail to Deliver in Water System Hack Attempt
In a recent cyber attack on nine Mexican government entities, hackers surprisingly used AI tools like Claude and Chat GPT to help breach the systems, but ultimately failed to cause significant harm. The attack, which included a January intrusion into a municipal water and sewage utility, revealed that while AI can facilitate malicious activity, it can't guarantee success.
US Agencies Issue Zero Trust Guidance for OT Security
US government agencies have just released a game-changing guide to help protect critical infrastructure systems with practical, layered security strategies. The new zero-trust guidance provides a tailored approach for operational technology environments, balancing safety and uptime needs with robust security measures.
OT Cybersecurity Sector Fears AI Exclusion
As artificial intelligence revolutionizes software security, the operational technology cybersecurity sector is sounding the alarm: will experts who safeguard factories, grids, and industrial sites be left behind? Pure-play OT security firms are pushing for a seat at the table, fearing they may be sidelined by the latest AI-driven initiatives.
