This disclosure describes techniques for verifying the identity of a user with a network access control (NAC) device in response to receiving a security assertion request for the user. To verify the identity of a user, an NAC device may, in response to receiving a security assertion request from a user agent executing on a client device, cause the user agent to redirect a session verification request to an NAC client executing on the client device. The NAC client may detect the session verification request, and provide information indicative of a valid network access session for the user to the NAC device. The NAC device may verify the identity of the user based on the information indicative of the valid network access session. In this way, an NAC device may verify the identity of a user without requiring the user to re-authenticate with the NAC device.

Network access session detection to provide single-sign on (SSO) functionality for a network access control device

In one example, a method includes predicting, by a network access control (NAC) device based on a device identifier in a request from a client device and a device usage history of the client device, a user associated with the client device, prior to completing a user authentication process, requesting, by the NAC device and from a directory server, session attributes for the predicted user, receiving, by the NAC device and from an authentication server, an indication of whether a user associated with the client device was successfully authenticated. The method includes determining, based on an identifier of the user, whether the predicted user is the user associated with the client device, and responsive to determining that the predicted user is the user associated with the client device, establishing, by the NAC and using the session attributes for the predicted user, a session between the client device and the network.

Predictive prefetching of attribute information

In general, techniques are described for seamlessly migrating a secure session established between a first computing device and a secure access appliance to a second computing device. In one example, a client computing device establishes a secure session with a secure access appliance. The client computing device receives a request via a communication channel from a second client computing device for secure session data for the first secure session usable by the second client computing device to establish a second secure session with the secure access appliance. The client computing device generates a message that includes the secure session data for the first secure session and sends the message to the second client computing device. Responsive to receiving the message, the second client computing device establishes a new secure session with the secure access appliance.

VPN session migration across clients

In general, techniques are described for dynamic resource allocation in virtual environments. A network device comprising physical resources, a first virtual machine (VM), a second VM and a hypervisor may implement these techniques. The first VM executes within a first partition of the physical resources to process a first portion of received network traffic, while the second MV executes within a second partition of the physical resources to process a second portion of the received network traffic. The first VM determines whether physical resources in addition to those allocated by way of the first partition are required to process the incoming network traffic and issues a request requesting additional physical resources based on the determination. Either the second VM or the hypervisor, in response to the request, dynamically reallocates at least a portion of the physical resources allocated to the second partition to the first partition.
