Abstract
A technique to stop lateral movement of ransomware between endpoints in a VLAN is disclosed. A security appliance is set as the default gateway for intra-LAN communication. Message traffic from compromised endpoints is detected. Attributes of ransomware may be detected in the message traffic, as well as attempts to circumvent the security appliance. Compromised devices may be quarantined.
