As the sophistication of cyber-attacks increases, understanding how to defend critical infrastructure systems—energy production, water, gas, and other vital systems—becomes more important, and heavily mandated. Industrial Network Security, Third Edition arms you with the knowledge you need to understand the vulnerabilities of these distributed supervisory and control systems. Authors Eric Knapp and Joel Langill examine the unique protocols and applications that are the foundation of Industrial Control Systems (ICS), and provide clear guidelines for their protection. This comprehensive reference gives you thorough understanding of the challenges facing critical infrastructures, new guidelines and security measures for infrastructure protection, knowledge of new and evolving security tools, and pointers on SCADA protocols and security implementation. Formal education is offered by many universities as well as organizations such as the Cybersecurity and Infrastructure Security Agency (CISA), the International Information System Security Certification Consortium (ISC2), the SANS Technology Institute, and others. At the same time, for many readers coming from backgrounds in both industrial control (“OT”) and information technology (“IT”), the idea of industrial cyber security will be entirely new. One thing that has definitely changed: it is no longer optional to ignore the subject of securing industrial automation and process control environments from the ever rising threat of a cyberattack.
