9. The method of claim 1 , wherein the network entity is a higher-order network entity that comprises a plurality of network entities, and determining the trust score for the higher-order network entity comprises aggregating trust scores for the plurality of network entities to determine the trust score for the higher-order network entity.

10. The method of claim 1 , wherein the method further comprises modifying, by the computing system, a testing pattern for the network entity based on the trust score for the network entity.

11. A computing system comprising:

one or more processors comprising processing circuitry configured to:

determine, based on one or more prerequisites, a trust score for a network entity in a computer network, the trust score for the network entity indicating a level of trust in the network entity, wherein each of the one or more prerequisites is a condition that must be satisfied for the trust score for the network entity not to be a minimum value; and

modify a traffic pattern of the computer network based on the trust score for the network entity; and

one or more storage devices configured to store the trust score for the network entity.

12. The computing system of claim 11 , wherein the one or more processors are configured such that, as part of modifying the traffic pattern, the one or more processors change, based on the trust score for the network entity, the traffic pattern to divert network traffic away from the network entity.

13. The computing system of claim 11 , wherein the prerequisites include whether the network entity uses a certified software release and whether the network entity uses a certified hardware release.

14. The computing system of claim 11 , wherein the one or more processors are configured such that, as part of determining the trust score for the network entity, the one or more processors:

determine the trust score for the network entity based on one or more variable factors for the network entity, wherein each of the one or more variable factors for the network entity corresponds to a current characteristic of the network entity.

15. The computing system of claim 11 , wherein the one or more processors are configured such that, as part of determining the trust score for the network entity, the one or more processors:

determine the trust score for the network entity based on one or more reputational factors for the network entity, wherein each of the reputational factors for the network entity is a function of specified historical events involving the network entity.

16. The computing system of claim 11 , wherein the one or more processors are configured such that, as part of determining the trust score for the network entity, the one or more processors:

determine a first sub-score based on the one or more prerequisites;

determine a second sub-score based on one or more variable factors of the network entity, wherein each of the one or more variable factors corresponds to a current characteristic of the network entity;

determine a third sub-score based on one or more reputational factors of the network entity, wherein each of the reputational factors is a function of specified historical events involving the network entity; and

determine the trust score for the network entity based on the first sub-score, the second sub-score, and the third sub-score.

17. The computing system of claim 11 , wherein the network entity is a higher-order network entity that comprises a plurality of network entities, and the one or more processors are configured to aggregate trust scores for the plurality of network entities to determine the trust score for the higher-order network entity.

18. A non-transitory computer-readable storage medium comprising instructions that, when executed, cause one or more programmable processors to:

determine, based on one or more prerequisites, a trust score for a network entity in a computer network, the trust score for the network entity indicating a level of trust in the network entity, wherein each of the one or more prerequisites is a condition that must be satisfied for the trust score for the network entity not to be a minimum value; and
