Abstract: Context-based network security is provided for streamlined access control over a computer network and components on the computer network. More particularly, methods, instructions on computer-readable media and systems are provided for collecting network context information about a client computer system connecting to the computer network, making the network context information available to various components on the computer network, and using the network context information to control the client computer system's (or a client application executing thereon) access to one or more network resources.
