Threat intelligence plays a critical role in protecting industrial control systems (ICS). Threat intelligence is information about current and potential threats to an organization that is gathered, analyzed, and shared in order to help improve security. This information can be used to identify and prioritize threats, understand the methods and tactics used by attackers, and develop more effective security strategies.
When it comes to protecting ICS, threat intelligence can be used to identify potential vulnerabilities and weaknesses in the systems that could be exploited by attackers. This information can be used to patch these vulnerabilities and to implement new security controls to protect the systems from attacks.
Threat intelligence can also be used to identify the tools, techniques, and procedures (TTPs) used by attackers that are known to target ICS. By understanding these TTPs, organizations can develop new security strategies to detect and prevent these types of attacks.
In addition, threat intelligence can be used to identify the types of attackers that are most likely to target ICS and to understand their motivations, which can help organizations to anticipate and respond to attacks more effectively.
Overall, threat intelligence can help organizations to stay informed about the latest cyber threats, to understand the risks they face, and to take appropriate measures to protect their ICS systems.
Also, many security vendors offer threat intelligence service which can provide this kind of information to clients. But if it is your own infrastructure, doing your own threat intelligence is also an important practice.
