US Patent 11044253 MAC authentication bypass endpoint database access control

An information security system that includes a switch operably coupled to a device. The switch includes a plurality of ports configured to provide network connectivity for one or more endpoint devices to a network. The device is configured to receive a MAC address and a device type for an endpoint device. The device is further configured to determine that the MAC address for the endpoint device is not present in a device information table that comprises MAC addresses of previously authenticated endpoint devices and to identify a device type category from a set of device type categories that correspond with the device type for the endpoint device. The device is further configured to identify one or more flags linked with the identified device type category and to set a port status for the port where the endpoint device is connected based on the identified one or more flags.
