Industrial control systems or ICSs are deployed and used globally, spanning various sectors and industries. The advent and maturity of universal communication protocols, such as TCP/IP, enable formerly isolated systems to be joined effectively and economically, creating large integrated systems. The rapid speed of these evolutions has allowed existing information technology security issues to spread into control systems. It results in cross-sector problems affecting all ICS users.
Advancement in digital technologies opens doors for cybercriminals. They find sophisticated ways to attack that are difficult to detect. The evolution of the cyber threat landscape brings out the emerging need for companies to strengthen their capabilities to analyze, detect, and evaluate cyber threats before evolving into security incidents. Patch management is a robust process in IT security. Appropriate vulnerability management through regular scans and updating software is a fundamental element of an effective IT security program. If done correctly, patch management eliminates cyber risks in IT systems.
