Abstract

A system and method for updating, monitoring, and controlling applications on a workstation. The workstation includes a workstation management module configured to detect the launch or request to access a network by an application. A workstation application server receives data associated with the application from the workstation. The application server module can determine one or more policies or categories to associate with the application by referencing an application inventory database. Once the application server module has the category or policy, it forwards a hash/policy table to the workstation management module. Upon receipt of the hash/policy table, the workstation management module applies the policy that is associated with the application to control network access by the application.

Claims

1. A method of updating a system which controls operation of programs on a workstation, the method comprising:

detecting a network access attempt by an application;

generating an application digest for the application;

determining whether the application is associated with one or more policies;

if the application is associated with one or more policies, then applying the one or more policies that are associated with the application;

if the application is not associated with a policy, then posting the application to a logging database;

uploading the logging database to an application server module;

determining whether the application is in an application inventory database, wherein the application is associated with a policy; and

if the application is not in the application inventory database of the application server module, then posting the application to a network access database,

if the application is in the application inventory database, then applying a policy associated with the application.

2. The method of claim 1 further comprising:

uploading the network access database to an application database factory;

determining whether each application has been previously analyzed by the application database factory;

for each application that was not previously analyzed, assigning one or more categories to at least one of each application or data associated with the application;

posting each application along with its selected one or more categories into a database of categorized applications; and

downloading the database of categorized applications for incorporation into the application inventory database.

3. The method of claim 2 further comprising:

updating a frequency in the application inventory database if the application is in the application inventory database; and

uploading the application inventory database to the application database factory.

4. The method of claim 1, wherein the one or more policies include allowing or disallowing the application to access the network.

5. The method of claim 1, wherein the one or more policies include allowing the application to access the network.

6. The method of claim 1, wherein the logging database further includes additional data associated with the application.

7. The method of claim 6, wherein the additional data includes a destination port number.

8. The method of claim 6, wherein the additional data includes a source IP address.

9. The method of claim 6, wherein the additional data includes a destination IP address.

10. The method of claim 6, wherein the additional data includes a source port number.

11. The method of claim 1 further comprising:

analyzing at least one of the application or additional data associated with the application for data characteristics that are indicative of the one or more categories; and

associating one or more indicators with the application.

12. The method of claim 11, wherein the analyzing the program data is performed on text strings that are associated with the application.

13. The method of claim 11, wherein the one or more indicators can include a category flag.

14. The method of claim 13 further comprising screening the application using the one or more indicators prior to uploading the network access database to the application database factory.

15. A method of updating a system which controls network access by programs on a workstation, the method comprising:

detecting a network access request of an application;

generating a hash value for the application, wherein the hash values includes network access data;

comparing the generated hash value to one or more hash values in a hash/policy table that includes one or more policies associated with the one or more hash values;

if the generated hash value matches one or more of the hash values in the hash/policy table, then applying the one or more policies that are associated with the one or more hash values;

if the generated hash value does not match a hash value in the hash/policy table, then posting the application to a logging database;

uploading the logging database to an application server module;

determining whether the application from the logging database is in an application inventory database; and

if the application is not in the application inventory database, then posting the application to a network access database.

16. The method of claim 15 further comprising scanning the logging database to determine a frequency count for the application.

17. The method of claim 15 further comprising:

uploading the network access database to an application database factory;

determining whether the application has been previously analyzed by the application database factory;

for each application that was not previously analyzed, selecting one or more categories to associate with that application;

posting each application along with its selected one or more categories into a database of applications; and

downloading the database of applications for incorporation into the application inventory database.
