Compliance validator for restricted network access control
A method, system, and computer program product for detecting and enforcing compliance with access requirements for a computer system in a restricted computer network. A compliance validation configuration file is created for the computer system. A maintenance service utility is configured to launch a compliance validation executable file at a specified time during operation of the computer system. A digital hash is generated for the compliance validation executable file and for the compliance validation configuration file. A determination is made if the computer system or a computer system user is a member of a configured restricted group. If the computer system or the computer system user is a member of a configured restricted group, a determination is made if a directory site code for a subnet of the restricted computer network to which the computer system is connected corresponds to a configured and allowed site. If the directory site code does not correspond to a configured and allowed site, compliance with access requirements are enforced. Enforcement actions can include a forced logoff of the computer system user, and/or a forced shutdown of the computer system.
1. A method, comprising:
updating either a compliance validation executable file or a compliance configuration file, based on a digital hash of the compliance validation executable file and the compliance validation configuration file; and
removing the compliance validation executable file and the compliance validation configuration file from a computer system, and enforcing compliance with access requirements when:
the update file has been removed; and
either the computer system is not a member of a configured restricted group or a computer system user is not a member of the configured restricted group;
wherein the enforcing comprises at least one of:
automatically logging the user off the computer system; and
automatically shutting down the computer system.
2. The method of claim 1 , comprising configuring a maintenance service utility to launch the compliance validation executable file at a specified time during operation of the computer system.
3. The method of claim 1 , comprising generating the digital hash for the compliance validation executable file and the compliance validation configuration file.
4. The method of claim 1 , comprising determining if the computer system or the computer system user is a member of the configured restricted group.
5. The method of claim 4 , comprising if the computer system or the computer system user is a member of the configured restricted group, determining if a directory site code for a subnet of the restricted computer network to which the computer system is connected corresponds to a configured and allowed site.
6. The method of claim 5 , comprising enforcing the compliance with access requirements if the directory site code does not correspond to the configured and allowed site.
7. The method of claim 1 , comprising determining if there are any updates at a location for either the compliance validation executable file or the compliance configuration file.
8. The method of claim 2 , wherein the step of configuring the maintenance service utility to launch a compliance validation executable file comprises selecting an activation time for the maintenance service utility.
9. A system, comprising:
a hardware processor that:
updates either a compliance validation executable file or a compliance configuration file, based on a digital hash of the compliance validation executable file and the compliance validation configuration file; and
removes the compliance validation executable file and the compliance validation configuration file from a computer system, and enforce compliance with access requirements when:
the update file has been removed; and
either the computer system or a computer system user is not a member of a configured restricted group;
wherein the enforcement comprises at least one of:
automatically log the user off the computer system; and
automatically shut down the computer system.
10. The system of claim 9 , wherein the processor configures a maintenance service utility to launch the compliance validation executable file at a specified time during operation of the computer system.
11. The system of claim 9 , wherein the processor generates the digital hash for the compliance validation executable file and the compliance validation configuration file.
12. The system of claim 9 , wherein the processor determines if the computer system or the computer system user is a member of the configured restricted group.
13. The system of claim 12 , wherein the processor determines if a directory site code for a subnet of the restricted computer network to which the computer system is connected corresponds to a configured and allowed site if the computer system or the computer system user is a member of the configured restricted group.
14. The system of claim 13 , wherein the processor enforces the compliance with access requirements if the directory site code does not correspond to the configured and allowed site.
15. The system of claim 9 , wherein the processor determines if there are any updates at a location for either the compliance validation executable file or the compliance configuration file.
16. The system of claim 10 , wherein the processor selects an activation time for the maintenance service utility when the maintenance service utility is configured.
17. A non-transitory computer program product comprising a computer readable medium having computer readable code embedded therein, the computer readable medium comprising:
program instructions that update either a compliance validation executable file or a compliance configuration file, based on a digital hash of the compliance validation executable file and the compliance validation configuration file;
program instructions that remove the compliance validation executable file and the compliance validation configuration file from a computer system, and enforce compliance with access requirements when:
the update file has been removed; and
either the computer system is not a member of a configured restricted group or a computer system user is not a member of the configured restricted group;
wherein the enforcing comprises at least one of:
automatically logging the user off the computer system; and
automatically shutting down the computer system.
18. The computer readable medium of claim 17 comprising program instructions that launch the compliance validation executable file at a specified time during operation of the computer system.
