Abstract

This disclosure describes techniques that include assessing trust in a system based on subjective factors. In one example, this disclosure describes a method that includes determining, by the computing system, a prerequisite score for a network entity in a computer network; determining, by the computing system, a subjective score for the network entity based on one or more subjective factors for the network entity, wherein each of the one or more subjective factors for the network entity corresponds to a subjective characteristic of the network entity; determining, by a computing system, a trust score for the network entity based on the prerequisite score and the subjective score; and modifying, by the computing system, operation of the computer network based on the trust score for the network entity.

Claims18

Dependent claims

A method comprising:

determining, by a computing system, a prerequisite score for a network entity in a computer network, wherein the prerequisite score is based on one or more prerequisite factors, and wherein each of the one or more prerequisite factors is a condition to be satisfied;
determining, by the computing system, a subjective score for the network entity based on one or more subjective factors for the network entity, wherein each of the one or more subjective factors for the network entity corresponds to a subjective characteristic representing an opinion of the network entity, and wherein determining the subjective score includes:
identifying information about how a trust score consumer values different types of subjective assessments, and
determining the subjective score further based on the information about how the trust score consumer values different types of subjective assessments;
determining, by the computing system and based on the prerequisite score and the subjective score, a trust score for the network entity;
and
modifying, by the computing system, operation of the computer network based on the trust score for the network entity.

4 more elements

A system comprising processing circuitry and a storage device, wherein the processing circuity has access to the storage device and is configured to:

determine a prerequisite score for a network entity in a computer network, wherein the prerequisite score is based on one or more prerequisite factors, and wherein each of the one or more prerequisite factors is a condition to be satisfied;
determine a subjective score for the network entity based on one or more subjective factors for the network entity, wherein each of the one or more subjective factors for the network entity corresponds to a subjective characteristic representing an opinion of the network entity, and wherein to determine the subjective score, the processing circuitry is further configured to:
identify information about how a trust score consumer values different types of subjective assessments, and
determine the subjective score further based on the information about how the trust score consumer values different types of subjective assessments;
determine, based on the prerequisite score and the subjective score, a trust score for the network entity;
and
modify operation of the computer network based on the trust score for the network entity.
