How Network Segmentation Can Help
Ransomware is dependent on freedom of lateral movement to spread far and wide, Nandakumara said.
“The fewer restrictions there are on this movement, the easier it will be for the attack to spread and the quicker it will progress,” he said. “Some ransomware attacks have been able to inflict catastrophic impact in a matter of minutes by exploiting this freedom. Segmentation limits this freedom, such that the attack can no longer spread from one compromised host to hundreds or thousands in a single hop. This slows down the spread, and ideally limits it.”
