Securing ICS infrastructure involves building the systems architecture to be secure from the ground up 'defense in depth.' The attacker may pass one roadblock, only to be faced by another and another. By employing next-generation firewalls, antivirus, intrusion detection, and prevention capabilities, the security teams can build the best defense to stop cyber-attacks.

Depending on the nature of the business, the management needs to consider the risk associated with the underlying system infrastructure and use of the next-gen solutions, including Machine Learning (ML), Artificial Intelligence (AI), and behavioral analysis to increase prevention efficacy, and speed.
