Abstract

In an apparatus for auditing security of a computer system, at least one secure application server is in communication with a global computer network. The secure application server is programmed to receive selectively security audit instruction data from a remote computer system via the global computer network. A plurality of scanning machines each are in communication with the global computer network and are programmed to execute selectively a security audit scan of the remote computer system via the global computer network. A central computer, having a memory, is configured as a database server and as a scheduler. The central computer is in communication with the secure application server and the scanning machine. The central computer is programmed to perform the following operations: evaluate a database to determine if a security audit scan is currently scheduled to be run for a user; determine which of the plurality of scanning machines is available to perform a security audit scan; copy scan-related information into a scanning machine determined to be available and instruct the scanning machine to begin scan; and record the results of the scan in the memory.

Claims

1. An apparatus for auditing security of a remote computer system, comprising:

a plurality of scanning machines in communication with a global computer network and programmed to execute selectively a security audit scan of the remote computer system via the global computer network, each scanning machine capable of conducting multiple types of security assessments; and

a central computer in communication with the plurality of scanning machines, programmed to perform operations comprising;

determining which of the plurality of scanning machines is available to perform the security audit scan by examining a schedule for each scanning machine to identify certain ones of the scanning machines that are conducting another security audit scan or are scheduled to conduct another security audit scan, the available scanning machines comprising all of the scanning machines except for the certain scanning machines;

copying scan-related information into one of the available scanning machines and instructing the scanning machine to begin the security audit scan; and

recording the results of the security audit scan in the memory.

2. The apparatus of claim 1, further comprising a web server in communication with the global computer network and programmed to receive security audit instruction data from the remote computer system.

3. The apparatus of claim 1, wherein the central computer is further programmed to

evaluate a database to determine if the security audit scan is currently scheduled to be run on one of the scanning machines;

and

issue a notification that the security audit scan is commencing.

4. The apparatus of claim 3, wherein when the central computer performs the operation in which the central computer records the results of the security audit scan, the central computer also copies the results to the database and copies a report to a file system on a database machine when the security audit scan is complete.

5. The apparatus of claim 1, wherein the central computer is further programmed to update the database to indicate that the security audit scan is complete.

6. The apparatus of claim 1, wherein the central computer is further programmed to send a signal representing completion of the security audit scan.

7. A method of auditing security, comprising the steps of:

determining with a central computer which of a plurality of scanning machines is available to perform a security audit scan by examining a schedule for each of the scanning machines to identify certain ones of the scanning machines that are conducting another security audit scan or are scheduled to conduct another security audit scan; and

instructing with the central computer one of the available scanning machines to access a remote computer system to perform the security audit scan of the remote computer system.

8. The method of claim 7, further comprising the step of recording with the central computer a result of the security audit scan in a computer memory.

9. The method of claim 7, further comprising the step of receiving at the available scanning machine scan related information for the security audit scan of the remote computer system, wherein the scan related information comprises at least one security assessment to be conducted during the security audit scan.

10. The method of claim 9, wherein the scan related information comprises an identity of at least one remote computer system upon which to conduct the security audit scan.

11. The method of claim 7, wherein the security audit scan comprises a vulnerability assessment.

12. The method of claim 7, further comprising the step of receiving from the available scanning machine a notification at the central computer that the security audit scan of the remote computer system is complete.

13. A method of auditing computer system security, comprising the steps of:

receiving at a central computer a schedule request for a security audit scan of a remote computer system;

determining at the central computer when the scheduled security audit scan of the remote computer system is to be executed;

in response to a determination that the scheduled security audit scan of the remote computer system is to be executed in a predetermined period of time, performing the following steps;

determining at the central computer which of a plurality of scanning machines is available to perform the scheduled security audit scan by identifying certain ones of the scanning machines that are conducting another security audit scan or are scheduled to conduct another security audit scan;

causing with the central computer a scanning system to establish communication with the remote computer system; and

causing with the central computer the scanning system to execute the scheduled security audit scan of the remote computer system.

14. The method of claim 13, further comprising the step of storing in a computer memory of the central computer a result of the security audit scan of the remote computer system, wherein the result is used for a statistical analysis of security on the remote computer system.

15. The method of claim 14, wherein the result comprises at least one vulnerability of the remote computer system detected during the security audit scan.

16. The method of claim 13, further comprising the step of determining with the central computer if the scheduled security audit scan is in the process of being conducted on the remote computer system.

17. The method of claim 13, further comprising the step of copying security audit scan data into a scanning system, wherein the security audit scan data comprises at least one security assessment to be conducted during the security audit scan.

18. The method of claim 17, wherein the security audit scan data further comprises an identity of at least one remote computer system upon which to conduct the scheduled security audit scan.

19. The method of claim 13, further comprising the step of sending from the central computer a message to a user interface prior to the commencement of the scheduled security audit scan.

20. The method of claim 13, further comprising the step of determining with the central computer if a request for an immediate security audit scan of one of a plurality of computer systems has been received in response to a determination that the scheduled security audit scan of the remote computer system will be executed outside of the predetermined period of time.
