Abstract: Techniques for conditional name resolution and configuration are provided. Calls made by applications to resolve hostnames through name resolution services are intercepted and processed unbeknownst to the applications. The calls are inspected for hostnames and the hostnames are lookup in a policy store for IP addresses. The IP addresses are supplied back to the applications as if IP addresses were provided by the name resolution services.

Abstract: Techniques for secure transparent switching between modes of a virtual private network (VPN) are provided. A principal, via a client, establishes a VPN session in a first mode of operation with a server. The principal subsequently requests a second mode of operation during the same VPN session. The VPN session is transparently transitioned to the second mode of operation without any interaction being required on the part of the principal and without terminating the original VPN session.

Abstract: Techniques for selective desktop control of virtual private networks (VPN's) in a multiuser environment are provided. A multiuser desktop/workstation includes a first user that establishes a VPN session on the desktop for accessing protected resources. Other users are permitted to simultaneously access non-protected resources of the desktop during the VPN session. Other users are also permitted to log into the desktop during the VPN session. However, if the other users attempt to access the protected resources, the access attempts are denied.

Abstract: Techniques for uninterrupted virtual private network (VPN) connection service with dynamic policy enforcement are provided. An existing VPN session between a VPN client and a VPN server detects a change in a VPN network being used for the existing VPN session. New credentials and new policies are received by the VPN client. The new credentials are automatically used to re-authenticate the VPN client to the change during the existing VPN session, and the new policies are dynamically used to enforce the new policies during the existing VPN session on the VPN client.

Abstract: Techniques for authenticating network connections are provided. A client makes a request to connect to a server via a client service. The server delays the request to acquire a signature for the client service from the requesting client's environment. The signature is compared against a known and previously verified signature. When the two signatures match, the server permits the connection between the client and the service via the client service. When the two signatures do not match, the server denies the connection between the client and the server and does not permit the client service to process a request to make that connection.

Abstract: Techniques for virtual private network (VPN) access are provided. A dynamic determination, in response to privileges, is made as to whether a principal and a device of a principal are to receive a thin client virtual private network (VPN) installation for a thin client VPN session between the principal and a remote site or whether a clientless VPN session is appropriate. Dynamic switching between the clientless VPN session and thin client VPN session is permissible when the principal supplies the appropriate credentials for such a switch.
