Abstract

Token-based firewall functionality. A request is received for access to a resource from a remote user device, the request received by an application firewall. A token is associated with the request. The token and associated information are stored in an event correlator coupled with the application firewall. The token is associated with one or more subsequent actions by the resource in response to receiving the request. A response to the request including the token is generated. The response with the token is transmitted to the remote user device via the application firewall. The application firewall analyzes the response and determines an action to be taken on the response based on the token and the associated information.

Claims

1. A method comprising:

receiving a request for access to a resource from a remote user device, the request received by an application-level firewall;

associating a token with the request, by the application-level firewall, wherein the token is added to a session context and the token is injected into multiple events that originate from the request to service the request during the session to allow the application-level firewall to correlate the request with a corresponding session wherein associating a token with the request comprises the application-level firewall modifying logic of the request to include the token;

storing the token and associated information in an event correlator communicatively coupled with the application-level firewall;

associating the token with one or more subsequent actions by the resource in response to receiving the request, wherein the one or more subsequent actions comprises at least generating a database query based on the request, the database query including the token in logic of the database query;

selectively applying one or more traffic management policies by the application-level firewall based on at least the session context having the token by at least identifying abnormalities in transactions through the application-level firewall utilizing at least a statistical model, wherein a total score is maintained over a session and can be updated by multiple host system entities; and

transmitting a response to the request with the token to the remote user device via the application firewall, wherein the application-level firewall analyzes the response and determines an action to be taken on the response based on the token and the associated information.

2. The method of claim 1 wherein the resource is part of a multitenant environment.

3. The method of claim 2 wherein the multitenant environment comprises a multitenant database environment, wherein the multitenant database environment stores data for multiple client entities each identified by a tenant identifier (ID) having one or more users associated with the tenant ID, wherein users of each of multiple client entities can only access data identified by a tenant ID associated with the respective client entity, and wherein the multitenant database is a hosted database provided by an entity separate from the client entities, and provides on-demand database service to the client entities.

4. The method of claim 1 wherein associating a token with the request comprises the application-level firewall inserting the token in at least a header of the request.

5. The method of claim 1 wherein associating a token with the request comprises the application-level firewall modifying logic of the request to include the token.

6. The method of claim 1 wherein the one or more subsequent actions comprises at least generating a file event based on the request, the file event including the token.

7. The method of claim 1 wherein the one or more subsequent actions comprises at least generating a network request based on the request, the network request including the token.

8. An article comprising a non-transitory computer-readable medium having stored thereon instructions that, when executed by one or more processors, are configurable to cause the one or more processors to:

receive a request for access to a resource from a remote user device, the request received by an application-level firewall;

associate a token with the request, by the application-level firewall, wherein the token is added to a session context and the token is injected into multiple events that originate from the request to service the request during the session to allow the application-level firewall to correlate the request with a corresponding session;

store the token and associated information in an event correlator communicatively coupled with the application-level firewall;

associate the token with one or more subsequent actions by the resource in response to receiving the request, wherein the one or more subsequent actions comprises at least generating a database query based on the request, the database query including the token in logic of the database query;

selectively apply one or more traffic management policies by the application-level firewall based on at least the session context having the token by at least identifying abnormalities in transactions through the application-level firewall utilizing at least a statistical model, wherein a total score is maintained over a session and can be updated by multiple host system entities; and

transmit a response to the request with the token to the remote user device via the application firewall, wherein the application-level firewall analyzes the response and determines an action to be taken on the response based on the token and the associated information.

9. The article of claim 8 wherein the resource is part of a multitenant environment.

10. The article of claim 9 wherein the multitenant environment comprises a multitenant database environment, wherein the multitenant database environment stores data for multiple client entities each identified by a tenant identifier (ID) having one or more users associated with the tenant ID, wherein users of each of multiple client entities can only access data identified by a tenant ID associated with the respective client entity, and wherein the multitenant database is a hosted database provided by an entity separate from the client entities, and provides on-demand database service to the client entities.

11. The article of claim 8 wherein the instructions that cause the one or more processors to associate a token with the request comprise instructions that, when executed, cause the one or more processors to insert the token in at least a header of the request.

12. The article of claim 8 wherein the instructions that cause the one or more processors to associate a token with the request comprise instructions that, when executed, cause the one or more processor to modify logic of the request to include the token.

13. The article of claim 8 wherein the one or more subsequent actions comprises at least generating a file event based on the request, the file event including the token.

14. The method of claim 8 wherein the one or more subsequent actions comprises at least generating a network request based on the request, the network request including the token.

15. A system comprising:

a computing environment coupled over a network to communicate with multiple user systems each having at least one memory device and one or more hardware processing devices coupled with the at least one memory device, the computing environment comprising at least an application-level firewall and an application, both coupled to receive traffic from the multiple user systems, the application-level firewall and the application to interact to receive a request for access to a resource from a remote user device, the request received by an application-level firewall

to associate a token with the request, by the application-level firewall, wherein the token is added to a session context and the token is injected into multiple events that originate from the request to service the request during the session to allow the application-level firewall to correlate the request with a corresponding session,

to store the token and associated information in an event correlator communicatively coupled with the application-level firewall,

to associate the token with one or more subsequent actions by the resource in response to receiving the request, wherein the one or more subsequent actions comprises at least generating a database query based on the request, the database query including the token in logic of the database query,

to selectively apply one or more traffic management policies by the application-level firewall based on at least the session context having the token by at least identifying abnormalities in transactions through the application-level firewall utilizing at least a statistical model, wherein a total score is maintained over a session and can be updated by multiple host system entities, and

to transmit a response to the request with the token to the remote user device via the application firewall, wherein the application-level firewall analyzes the response and determines an action to be taken on the response based on the token and the associated information.

16. The system of claim 15 wherein associating a token with the request comprises the firewall inserting the token in at least a header of the request.

17. The system of claim 15 wherein associating a token with the request comprises the firewall modifying logic of the request to include the token.

18. The system of claim 15 wherein the one or more subsequent actions comprises at least generating a file event based on the request, the file event including the token.

19. The system of claim 15 wherein the one or more subsequent actions comprises at least generating a network request based on the request, the network request including the token.
