CIS Benchmarks are a set of globally recognised best practices for securing individual software applications and operating systems. In an industrial security context, applying these benchmarks involves hardening workstations, servers, and network equipment to a verified, secure standard. This includes disabling unnecessary services, closing unused ports, and enforcing strong password policies. By following these vendor-neutral guidelines, organisations can establish a robust security baseline for their entire operational technology estate. Learn about hardening as part of boundary defence.
