Network appliance for securely quarantining a node on a network

摘要

An apparatus, system, and method for managing dynamic network access control. The invention provides services and controlled network access that includes quarantining nodes so that they may be identified, audited, and provided an opportunity to be brought into compliance with a security policy. The invention is configured to detect a device seeking to join the network, and determine if the device is allowed to join the network. If the invention determines that the device is not to be allowed, the device may be quarantined using a VLAN. The suspect device may then be audited for vulnerabilities. If vulnerabilities are identified, remediation may be employed to guide the suspect device, a user, and/or administrator of the suspect device towards a resolution of the vulnerabilities, such that the device may be reconfigured for acceptance onto the network.
