A scalable access filter that is used together with others like it in a virtual private network to control access by users at clients in the network to information resources provided by servers in the network. Each access filter uses a local copy of an access control data base to determine whether an access request is made by a user. Each user belongs to one or more user groups and each information resource belongs to one or more information sets. Access is permitted or denied according to access policies which define access in terms of the user groups and information sets. The first access filter in the path performs the access check, encrypts and authenticates the request; the other access filters in the path do not repeat the access check. The interface used by applications to determine whether a user has access to an entity is now an SQL entity. The policy server assembles the information needed for the response to the query from various information sources, including source external to the policy server.
1. A method for positive access control regarding one or more resources in a network, the method comprising:
storing information in memory regarding a plurality of users, the information for each user including a dossier including one or more attributes indicative of custom group memberships for the user;
receiving an access request from a client device associated with a user of the plurality of users, the access request regarding access to at least one of the one or more resources and including authentication information; and
executing instructions stored in memory, wherein execution of the instructions by a processor:
retrieves a dossier for the user based on the authentication information provided in the request,
identifies that the user belongs to a custom user group allowed to access the at least one resource requested by the access request, the identification based on the one or more attributes in the retrieved dossier, and
moves a session associated with allowing the user to access the at least one resource, the session moved to a server dedicated to providing guaranteed fast responses during congested time periods.
2. The method of claim 1 , wherein the instructions stored in memory and executed by the processor are further executable to automatically create custom groups of users from the plurality of users based on the dossier for each user.
3. The method of claim 1 , wherein the server dedicated to providing guaranteed fast responses allows different custom groups of users different levels of access to content controlled by the server based on membership in one or more custom groups.
4. the method of claim 1 , wherein the server dedicated to providing guaranteed fast responses allows different custom groups of users different levels of access to services controlled by the server based on membership in one or more custom groups.
5. The method of claim 1 , wherein the one or more groups are subject to further authentication based on a user to device pairing.
6. The method of claim 1 , further comprising routing traffic to the server dedicated to providing guaranteed fast responses based on the user dossier.
7. The method of claim 6 , wherein the routing is controlled by a policy enabled network router.
8. The method of claim 6 , wherein the routing includes creation of an end-to-end encrypted network tunnel.
9. The method of claim 6 , wherein the routing includes creation of a virtual private network.
10. The method of claim 1 , wherein the retrieved dossier is distributed over a network.
