20130091534 | NETWORK APPLIANCE FOR CUSTOMIZABLE QUARANTINING OF A NODE ON A NETWORK - A system, method, and apparatus are directed to managing access to a network. An agent may intercept a network packet transmitted by an enforcement point in response to a request from a device to join the network. The agent identifies, based on the network packet, a port number on the enforcement point at which the request is received. The agent may transmit the port number to a NACA to enable security enforcement operations to be performed on the device. Another device may reside outside the quarantined network and be enabled by the NACA to direct a remediation measure to be performed on the device using at least the port number. The NACA may spoof an ARP response with an address of the NACA to restrict access to resources. The NACA may also place the device into one of a plurality of quarantined networks. | 04-11-2013 |
