Industrial control systems security with Elastic Security and Zeek

Industrial control systems (ICS) have traditionally operated in isolation, but the advent of Industry 4.0 has increased their connectivity, introducing new security challenges. These systems, crucial to sectors like energy, transportation, and telecommunications, integrate both information and operational technologies, necessitating unique security measures. Elastic Security and Zeek offer solutions to these challenges by providing robust network security, asset inventory management, and threat intelligence integration. Elastic's machine learning capabilities enhance anomaly detection, while Zeek's network detection frameworks ensure comprehensive monitoring of ICS protocols without disrupting operations. Additionally, Elastic Defend provides endpoint security, addressing the specific vulnerabilities of ICS environments, such as outdated software and lack of internet access. The use of threat intelligence and the MITRE ICS ATT&CK matrix further aids in understanding and mitigating potential threats, making ICS security more resilient.
