Abstract

A prevention-based network auditing system includes a central compliance server providing a user interface allowing a user to schedule and configure a network audit. The configured audit is stored in an audit repository until its scheduled time. At such a time, the compliance server automatically invokes one or more audit servers to gather information about the network. The compliance server receives the gathered information and electronically applies a network policy to the information for determining compliance with the policy. A remediation task may be generated if the policy has been violated, and the task monitored until its completion.

Claims

1. A method comprising:

providing a user interface to a computer for allowing a user to configure a network audit;

storing network audit configuration information in a data store;

initiating the network audit based on the configuration information to gather information about a network;

testing a network policy prior to deployment of the network policy in a scheduled audit, wherein the network policy is tested against past audit results stored in an audit repository, and wherein one or more recommendations are provided in response to the testing of the network policy, the one or more recommendations including additional rules to be added to the network policy;

applying the network policy;

determining compliance with the network policy;

generating a task based on the compliance determination;

assigning the task for execution; and

monitoring a status of the task, wherein a rollback function is provided that allows one or more system components to be returned to a previous version.

2. The method of claim 1, wherein the configuration information includes audit scheduling information.

3. The method of claim 1, wherein the task is modifying a network feature.

4. The method of claim 1 further comprising verifying the completion of the task.

5. The method of claim 4, wherein the verifying comprises:

re-auditing the network based on the configuration information to newly gathered information about the network; and

re-applying the network policy to the newly gathered network information.

6. The method of claim 1, wherein the task includes a remediation task.

7. The method of claim 1, wherein the status of the task is set to an unassigned state in response to the generation of the task.

8. The method of claim 1, wherein the task is assigned to an entity based on at least one of a role and a geographic responsibility.

9. The method of claim 1, wherein the status of the task is set to an assigned state in response to the assignment of the task for execution.

10. The method of claim 1, further comprising transmitting a notification to an entity to which the task is assigned, wherein the notification includes a hyperlink to a remediation update function.

11. The method of claim 10, wherein the hyperlink is utilized for updating the status of the task.

12. The method of claim 1, further comprising automatically distributing the task to a selected plurality of audit scanners for auditing the network based on a load.

13. The method of claim 1, wherein the task is automatically prioritized based on at least one of severity and length of exposure.

14. The method of claim 1, wherein the indication of the completion of the task is transmitted via e-mail.

15. The method of claim 1, wherein the task is assigned to a third-party remediation system.

16. A system comprising:

a user interface allowing a user to configure a network audit;

a data store storing network audit configuration information;

means for initiating the network audit based on the configuration information to gather information about a network;

means for testing a network policy prior to deployment of the network policy in a scheduled audit, wherein the network policy is tested against past audit results stored in an audit repository, and wherein one or more recommendations are provided in response to the testing of the network policy, the one or more recommendations including additional rules to be added to the network policy;

means for applying the network policy;

means for determining compliance with the network policy;

means for generating a task based on the compliance determination;

means for assigning the task for execution; and

means for monitoring a status of the task, wherein a rollback function is provided that allows one or more system components to be returned to a previous version.

17. The system of claim 16, wherein the configuration information includes audit scheduling information.

18. The system of claim 16, wherein the task is modifying a network feature.

19. The system of claim 16, further comprising means for verifying the completion of the task.

20. The system of claim 19, wherein the means for verifying comprises:

means for re-auditing the network based on the configuration information to newly gathered information about the network; and

means for re-applying the network policy to the newly gathered network information.
