Managing installation of applications on a computing device

1. A system, comprising:

a memory device; and

at least one computing device comprising a processor in communication with the memory device, the at least one computing device being configured to manage installation of an application program on the at least one computing device via an agent registered with an operating system of the at least one computing device, wherein the at least one computing device is configured to:

receive a notification in response to a user request to mount a disk image comprising the application program;

generate metadata associated with the disk image in response to receiving the notification;

determine an action to take based on a based on the metadata associated with the disk image; and

install the application program using privileges of the agent without changing privileges of an account of a current user.

2. The system of claim 1 , wherein the at least one computing device is further configured to:

generate a hash of content of the application program; and

search for the hash of content against a plurality of records in a policy file to identify a matching record of the plurality of records, wherein the metadata comprises the matching record.

3. The system of claim 1 , wherein the at least one computing device is further configured to:

determine that the application program is digitally signed; and

in response to the application program being digitally signed, retrieving a certificate and hash corresponding to the application program.

4. The system of claim 1 , wherein the at least one computing device is further configured to consult a policy file to determine the action to take based on the metadata associated with the disk image.

5. The system of claim 1 , wherein the metadata comprises at least one of a current path of the disk image and current session information.

6. The system of claim 1 , wherein the at least one computing device is further configured to perform a call to an application programming interface (API) function call of the operating system to generate at least a portion of the metadata.

7. The system of claim 1 , wherein the at least one computing device is further configured to determine whether to allow mounting of the disk image responsive to the notification and prior to determining the action to take.

8. A method, comprising:

receiving, via an agent of at least one computing device, a notification in response to a user request to mount a disk image comprising an application program;

gathering, via the agent of the at least one computing device, metadata associated with the disk image;

determining, via the agent of the at least one computing device, an action to take based on the metadata associated with the disk image; and

installing, via the agent of the at least one computing device, the application program according to the action to take using privileges of the agent without changing privileges of a user account.

9. The method of claim 8 , further comprising capturing the metadata related to the disk image.

10. The method of claim 8 , wherein the application program comprises an application bundle.

11. The method of claim 10 , further comprising generating, via the agent of the at least one computing device, a hash of the application bundle.

12. The method of claim 11 , further comprising generating, via the agent of the at least one computing device, the hash of the application bundle by iterating through all files in the application bundle.

13. The method of claim 8 , further comprising:

receiving, via the agent of the at least one computing device, a second notification in response to a second user request to mount a second disk image comprising a second application program;

gathering, via the agent of the at least one computing device, a second metadata associated with the second disk image;

determining, via the agent of the at least one computing device, a second action to take based on the second metadata associated with the second disk image; and

preventing, via the agent of the at least one computing device, the second disk image from being mounted based on the second action.

14. A non-transitory computer-readable medium embodying an agent that, when executed by at least one computing device, causes the at least one computing device to:

receive a notification in response to a user request to mount a disk image comprising an application bundle;

consult a policy file to determine an action to take based on metadata associated with the application bundle; and

based on the action to take, install the application bundle using privileges of the agent without changing privileges of an account of a current user.

15. The non-transitory computer-readable medium of claim 14 , wherein the agent further causes the at least one computing device to register with an operating system to receive the notification concerning mounting of the disk image.

16. The non-transitory computer-readable medium of claim 14 , wherein the policy file comprises a plurality of rules defining conditions under which the agent operates.

17. The non-transitory computer-readable medium of claim 14 , wherein the policy file is stored in a secure location on a policy server.

18. The non-transitory computer-readable medium of claim 14 , wherein the agent further causes the at least one computing device to install the application bundle by copying the application bundle to a privileged system location.

19. The non-transitory computer-readable medium of claim 14 , wherein the application bundle comprises a plurality of files in a folder.

20. The non-transitory computer-readable medium of claim 14 , wherein the metadata comprises at least one of: a file name of the disk image, a hash of the disk image, and a signature of the disk image.
