Healthcare Organizations Struggling to Implement Primary Method of Blocking Lateral Movement
A study of security leaders from the healthcare and manufacturing industries found that while there is an almost universal desire to deploy modern microsegmentation, more than 90% of respondents said they had protected fewer than 80% of critical systems, despite almost half admitting to falling victim to lateral movement attacks in the past year. In healthcare, fewer than 6% of respondents said that their organization had implemented microsegmentation across 80% or more of their critical systems. Microsegmentation is a cybersecurity technique that divides networks into small, distinct, and isolated zones to secure workloads, applications, or devices. Traditional network segmentation, such as Virtual Local Area Networks (VLANs), creates broad segmented zones, whereas microsegmentation applies security policies at the individual workload or application level. Microsegmentation allows organizations to implement East-West traffic control within their data center, rather than only North-South traffic controls for identifying traffic leaving the network. It provides deep visibility into...
