A strong base for OT/ICS security needs real-time access of the entire hardware, software and firmware in the network, customer’s data, active accounts information, patches status, susceptibilities, network system configurations, windows updates, implanted system backplanes, the status of diverse security components such as application firewalls, whitelisting, antivirus,
The purpose of an ICS patch management program aims to ensure that ICS is secured and executed by testing, implementing, and deploying trusted patches. This approach helps in ensuring that the industrial control system is updated and is defended against cyber threat actors and malicious operators. It is applicable for all ICS software and hardware elements in both Operational Technology (OT) and Information Technology (IT).
