Industrial Internet Security Protection Based on an Industrial Firewall

Abstract

A crucial step in the development of a security system for the industrial Internet is the implementation of an industrial firewall as the first line of defense for the multi-layer defense-in-depth system and an important safeguard for industrial network security. In the design, development, deployment, application, and maintenance of industrial firewalls, the firewall performance and architecture are vital aspects. This thesis focuses on the analysis and discussion of the requirements and abilities of an industrial firewall in terms of adaptability, network isolation, industrial communication protocol identification, filtering and analysis, real-time performance and reliability, and self-protection.
