How to Effectively Implement ISA 99/IEC 62443

As the de facto global standard for security of Industrial Control System (ICS) networks, IEC 62443, formerly known as ISA 99, plays a major role in evaluating network vulnerabilities and reducing threats and failures. This document covers many of the key technical requirements of IEC 62443. It also describes how Forescout eyeInspect (formerly SilentDefense™) helps ICS network operators implement and comply with the ICS security requirements in each of these categories:
- Identification and authentication control
- Use control
- System integrity
- Data confidentiality
- Restricted data flow
- Timely response to events
- Resource availability
