Abstract

A set of attributes of a particular asset of a computing environment is identified that are determined from data collected by one or more utilities in the computing environment. A criticality rating is automatically determined for the particular asset based at least in part on the set of attributes. A security activity is caused to be performed relating to the particular asset based on the automatically determined criticality rating of the particular asset.

Claims

1. A method, comprising:

identifying a set of attributes of an asset of a computing environment, wherein the set of attributes identifies one or more users and a context of use of the asset by the one or more users;

determining, using at least one processor device, a criticality rating value for the asset based at least in part on the one or more users and the context of use, wherein the criticality rating value indicates an impact of damage to or loss of the asset, and the criticality rating value is determined in response to a countermeasure deployment involving the asset or an attempt to launch the asset or an application hosted by or interacting with the asset;

calculating a risk measure for the asset from the criticality rating value, vulnerability detection data identifying vulnerabilities of the asset, and countermeasure detection data identifying countermeasures deployed on the asset; and

causing a security activity to be performed based at least in part on the risk measure for the asset.

2. The method of claim 1, wherein the set of attributes are determined from data collected using an agent deployed on a computing device of the asset.

3. The method of claim 1, wherein the security activity includes a risk assessment using the criticality rating value as an input.

4. The method of claim 1, wherein the causing the security activity to be performed includes determining a priority for the security activity based on the criticality rating value.

5. The method of claim 1, wherein the criticality rating value is based on a detection that the asset is monitored, locked, encrypted, secured, or is protected.

6. The method of claim 1, wherein the criticality rating value is based on a whitelist used by, entrusted with, deployed on, or identifying the asset or a host thereof.

7. The method of claim 1, further comprising:

determining that the criticality rating value does not exist for the asset based on an event involving the asset, wherein the set of attributes is determined from data collected by one or more utilities in the computing environment.

8. At least one non-transitory storage medium having instructions stored thereon, wherein the instructions, when executed on a machine, cause the machine to perform a method comprising:

identifying a set of attributes of an asset of a computing environment, wherein the set of attributes identifies one or more users and a context of use of the asset by the one or more users;

determining, using at least one processor device, a criticality rating value for the asset based at least in part on the one or more users and the context of use, wherein the criticality rating value indicates an impact of damage to or loss of the asset, and the criticality rating value is determined in response to a countermeasure deployment involving the asset or an attempt to launch the asset or an application hosted by or interacting with the asset;

calculating a risk measure for the asset from the criticality rating value, vulnerability detection data identifying vulnerabilities of the asset, and countermeasure detection data identifying countermeasures deployed on the asset; and

causing a security activity to be performed based at least in part on the risk measure for the asset.

9. The medium of claim 8, wherein the set of attributes are determined from data collected using an agent deployed on a computing device of the asset.

10. The medium of claim 8, wherein the security activity includes a risk assessment using the criticality rating value as an input.

11. The medium of claim 8, wherein the causing the security activity to be performed includes determining a priority for the security activity based on the criticality rating value.

12. The medium of claim 8, wherein the criticality rating value is based on a detection that the asset is monitored, locked, encrypted, secured, or is protected.

13. The medium of claim 8, wherein the criticality rating value is based on a whitelist used by, entrusted with, deployed on, or identifying the asset or a host thereof.

14. The medium of claim 8, the method further comprising:

determining that the criticality rating value does not exist for the asset based on an event involving the asset, wherein the set of attributes is determined from data collected by one or more utilities in the computing environment.

15. A system, comprising:

at least one memory element that stores instructions; and

at least one processor device that executes the instructions to

identify a set of attributes of an asset of a computing environment, wherein the set of attributes identifies one or more users and a context of use of the asset by the one or more users;

determine a criticality rating value for the asset based at least in part on the one or more users and the context of use, wherein the criticality rating value indicates an impact of damage to or loss of the asset, and the criticality rating value is determined in response to a countermeasure deployment involving the asset or an attempt to launch the asset or an application hosted by or interacting with the asset;

calculate a risk measure for the asset from the criticality rating value, vulnerability detection data identifying vulnerabilities of the asset, and countermeasure detection data identifying countermeasures deployed on the asset; and

cause a security activity to be performed based at least in part on the risk measure for the asset.

16. The system of claim 15, wherein the set of attributes are determined from data collected using an agent deployed on a computing device of the asset.

17. The system of claim 15, wherein the security activity includes a risk assessment using the criticality rating value as an input.

18. The system of claim 15, wherein the causing the security activity to be performed includes determining a priority for the security activity based on the criticality rating value.

19. The system of claim 15, wherein the criticality rating value is based on a detection that the asset is monitored, locked, encrypted, secured, or is protected.

20. The system of claim 15, wherein the at least one processor device executes the instructions to determine that the criticality rating value does not exist for the asset based on an event involving the asset, and the set of attributes is determined from data collected by one or more utilities in the computing environment.
