Abstract
A scalable access filter is used in a virtual private network to control access by users at clients in the network to information resources provided by servers in the network. Access is permitted or denied according to access policies which define access in terms of the user groups and information sets. The access filter in the path performs the access check, encrypts and authenticates the request.
