Internetwork authentication
View Patent ↗A technique for network authentication interoperability involves initiating an authentication procedure on a first network, authenticating on a second network, and allowing access at the first network. The technique can include filtering access to a network, thereby restricting access to users with acceptable credentials. Offering a service that incorporates these techniques can enable incorporation of the techniques into an existing system with minimal impact to network configuration.
1. A method comprising:
receiving a request for a policy-based identity routing service for a first network;
providing a local authoritative user datastore interface (LAUDI) to a network device of the first network;
obtaining a set of rules for identity routing to the first network;
establishing a connection with the LAUDI on the network device of the first network;
filtering authentication requests received from at least one other network, including a second network, to resolve the authentication requests with either on-network or off-network authentication;
wherein a successful authentication result, from the LAUDI, for a station associated with the second network, is indicative of the station being allowed access to services on the second network including services provided by the first network and the set of rules for identity routing to the first network are used, at least in part, in providing the services on the second network.
2. The method of claim 1 , wherein the LAUDI is provided to the network device of the first network through download.
3. The method of claim 1 , wherein the LAUDI is preinstalled on the network device of the first network.
4. The method of claim 1 , wherein the set of rules for identity routing to the first network are provided by an agent of the first network.
5. The method of claim 1 , wherein the rules for identity routing to the first network include filter rules used in filtering the authentication requests received from the at least one other network, including the second network.
6. The method of claim 1 , further comprising:
receiving an authentication request from the second network for the station;
routing the authentication request based on a rule of the set of rules to the LAUDI;
receiving an authentication result from the LAUDI;
sending the authentication result to the second network;
wherein if the authentication result is the successful authentication result, then the station being allowed access to the services on the second network.
7. The method of claim 1 , wherein the connection between the LAUDI and the network device is a persistent connection.
8. The method of claim 1 , wherein the connection between the LAUDI and the network device is established using transport layer security.
9. The method of claim 1 , further comprising obtaining a set of rules for filtering and identity routing to the first network, wherein the successful authentication result is indicative of station credentials sufficient to avoid filtering an authentication request associated with the station in accordance with the filtering rules and sufficient to permit routing the authentication request to the first network in accordance with the identity routing rules.
10. A system comprising:
a local authoritative user datastore interface (LAUDI) provided to a network device of a first network;
an online authentication proxy comprising a processor and memory storing instructions configured to:
receive a request for a policy-based identity routing service for the first network;
obtain a set of rules for identity routing to the first network;
establish a connection with the LAUDI on the network device of the first network;
filter authentication requests received from at least one other network, including a second network, to resolve the authentication requests with either on-network or off-network authentication;
wherein a successful authentication result, from the LAUDI, for a station associated with the second network, is indicative of the station being allowed access to services on the second network including services provided by the first network and the set of rules for identity routing to the first network are used, at least in part, in providing the services on the second network.
11. The system of claim 10 , wherein the LAUDI is provided to the network device of the first network through download.
12. The system of claim 10 , wherein the LAUDI is preinstalled on the network device of the first network.
13. The system of claim 10 , wherein the set of rules for identity routing to the first network are provided by an agent of the first network.
14. The system of claim 10 , wherein the rules for identity routing to the first network include filter rules used in filtering the authentication requests received from the at least one other network, including the second network.
15. The system of claim 10 , wherein the online authentication proxy is further configured to:
receive an authentication request from the second network for the station;
route the authentication request based on a rule of the set of rules to the LAUDI;
receive an authentication result from the LAUDI;
send the authentication result to the second network;
wherein if the authentication result is the successful authentication result, then the station being allowed access to the services on the second network.
16. The system of claim 10 , wherein the connection between the LAUDI and the network device is a persistent connection.
17. The system of claim 10 , wherein the connection between the LAUDI and the network device is established using transport layer security.
18. The system of claim 10 , wherein the online authentication proxy is further configured to obtain a set of rules for filtering and identity routing to the first network, wherein the successful authentication result is indicative of station credentials sufficient to avoid filtering an authentication request associated with the station in accordance with the filtering rules and sufficient to permit routing the authentication request to the first network in accordance with the identity routing rules.
