There is no silver bullet in cybersecurity, but some strategies, like network segmentation, provide more bang for the cybersecurity buck. Effective network segmentation requires thorough knowledge about what is in the environment. This knowledge includes information beyond just the endpoints, such as regarding normal operational process workflows, as well as expected network communications. ICS cybersecurity expert Galina Antova discusses the priceless role network segmentation plays in protecting OT networks. Ms. Antova further addresses the challenges of applying proper network segmentation, as well as methods to overcome these challenges, including the value of OT network monitoring for organizations who have little to no prior asset management. When done effectively, network segmentation, along with other controls, reduces weaknesses and may convince an attacker to move to a less-fortified target. SecurityWeek.
