Abstract
A technique to improve security for a VLAN is disclosed. A security appliance is set as the gateway for intra-LAN communication. Message traffic is analyzed and anomalies are detected relative to normal message traffic that correspond to device health problems that may require service by a field technician. A network switch may be configured to drop certain types of Address Resolution Protocol messages from selected ports to aid in setting a security appliance as the gateway.
