Abstract
In network access controlled networks, it is desirable to prevent access to the network by any non-authenticated entities. Access control may be established through a trusted agent that, in some embodiments, may be implemented with a management co-processor. In some cases, active management technology may establish a connection while a host is inactive. Then, after the host becomes active, the host can attempt to use the management co-processor connection without obtaining the necessary authentications. This may be prevented, in some embodiments, by scanning for an active host and, if such an active host is found, blocking the host from using a layer 2 authentication channel unless the host is properly authenticated and has a proper Internet Protocol address.
