In the wake of a flood of cyberattacks, the U.S. Departments of Commerce and Homeland Security have drafted a report on enhancing resilience against botnets. Andrea Carcano, Co-Founder and Chief Product Officer at Nozomi Networks commented below.

“One approach to blocking Bots from getting into industrial control systems for critical infrastructure is to leverage network segmentation designed for cybersecurity protection. Specifically for industrial cybersecurity, following the IEC 62443 network segmentation guidelines which recommends grouping devices with similar security requirements behind a secure conduit like a firewall is the goal. This way only whitelisted communications would get through to key areas of the control network, blocking DDOS attacks from Botnets from impacting ICS.”
