Abstract

Claims (35)

1. A method for determining when results from a first criteria scan are deleted from a computing device, the method comprising:

performing the first criteria scan on the computing device, wherein the first criteria scan determines a status of a virus scanner and critical patches on the computing device;

storing results of the first criteria scan on the computing device, wherein the stored results of the first criteria scan comprise the status of the virus scanner, and the critical patches on the computing device;

disconnecting the computing device from a first network;

broadcasting an inform packet to at least one server; and

if a response to the inform packet is received within a defined time parameter, deleting the stored results of the first criteria scan in their entirety if the computing device determines that the at least one server is not part of the first network such that the computing device is required to perform a second criteria scan before the computing device is allowed to reconnect to the first network.

2. The method of claim 1 , wherein the inform packet comprises a Dynamic Host Configuration Protocol (DHCP) packet.

3. The method of claim 1 , wherein the at least one server comprises a DHCP server.

4. The method of claim 1 , wherein the inform packet comprises a special option in an upper range.

5. The method of claim 4 , wherein the special option in the upper range comprises a request for a response to the inform packet.

6. The method of claim 1 , wherein the response is digitally signed using a private key associated with the first network.

7. The method of claim 1 , wherein the response comprises a Media Access Control (MAC) address of the computing device.

8. The method of claim 7 , wherein the MAC address is digitally signed with a private key associated with the first network.

9. The method of claim 6 , further comprising verifying a digital signature of the response by the first network, and maintaining the stored results of the first criteria scan based on the verification.

10. The method of claim 1 , further comprising:

if the response to the inform packet is not received within the defined time parameter, deleting the stored results of the first criteria scan.

11. The method of claim 1 , further comprising performing the second criteria scan if the results of the first criteria scan are deleted from the computing device.

12. The method of claim 11 , further comprising placing the computing device on a network that is not part of the first network.

13. The method of claim 1 , further comprising monitoring a plurality of network adapters for a network address.

14. A computer system that is configured to determine when results from a first criteria scan are deleted, the computer system comprising:

a processor;

memory in electronic communication with the processor;

instructions stored in the memory, the instructions being executable to:

perform the first criteria scan on the computer system, wherein the first criteria scan determines a status of a virus scanner and critical patches on the computer system;

store results of the first criteria scan on the computer system, wherein the stored results of the first criteria scan comprise the status of the virus scanner and the critical patches on the computer system; disconnect the computer system from a first network; broadcast an inform packet to at least one server; and

if a response to the inform packet is received within a defined time parameter, delete the stored results of the first criteria scan in their entirety if the computer system determines that the at least one server is not part of the first network such that the computer system is required to perform a second criteria scan before the computer system is allowed to reconnect to the first network.

15. The computer system of claim 14 , wherein the inform packet comprises a Dynamic Host Configuration Protocol (DHCP) packet.

16. The computer system of claim 14 , wherein the server comprises a DHCP server.

17. The computer system of claim 14 , wherein the response is digitally signed with a private key associated with the first network.

18. A non-transitory computer-readable medium comprising executable instructions to determine when results from a first criteria scan are deleted from a computing device, the instructions being executable to:

perform the first criteria scan on the computing device, wherein the first criteria scan determines a status of a virus scanner and critical patches on the computing device;

store results of the first criteria scan on the computing device, wherein the stored results of the first criteria scan comprise the status of the virus scanner and the critical patches on the computing device; disconnect the computing device from a first network; broadcast an inform packet to at least one server; and

if a response to the inform packet is received within a defined time parameter, delete the stored results of the first criteria scan in their entirety if the computing device determines that the at least one server is not part of the first network such that the computing device is required to perform a second criteria scan before the computing device is allowed to reconnect to the first network.

19. The non-transitory computer-readable medium of claim 18 , wherein the inform packet comprises a Dynamic Host Configuration Protocol (DHCP) packet.

20. The non-transitory computer-readable medium of claim 18 , wherein the server comprises a DHCP server.
