APPLYING A GROUP BASED POLICY TO NETWORK TRAFFIC FROM A CLIENT

Some examples relate to a proxy service on a network device for applying a group based policy (GBP) to network traffic from a client. In an example, a proxy service on a network device is used to intercept a network access request message, pertaining to a client, from an access device. The proxy service forwards the network access request message to an authentication server. The server responds by sending a network access response message to the access device. The proxy service intercepts the network access response message from the authentication server and obtains the role information of the client from the network access response message. In response to receiving network traffic from the client, the proxy service identifies a GBP corresponding to the role information of the client and applies the GBP to the network traffic from the client.
