Abstract

A method, system and computer-usable medium for adaptively assessing risk associated with an endpoint, comprising: determining a risk level corresponding to an entity associated with an endpoint; selecting a frequency and a duration of an endpoint monitoring interval; collecting user behavior to collect user behavior associated with the entity for the duration of the endpoint monitoring interval via the endpoint; processing the user behavior to generate a current risk score for the entity; comparing the current risk score of the user to historical risk scores to determine whether a risk score of a user has changed; and changing the risk score of the user to the current risk score when the risk score of the user has changed.

Claims

1. A computer-implementable method for adaptively assessing risk associated with an endpoint, comprising:

determining a risk level corresponding to an entity associated with an endpoint;

selecting a frequency and a duration of an endpoint monitoring interval;

collecting user behavior associated with the entity for the duration of the endpoint monitoring interval via the endpoint;

processing the user behavior to generate a current risk score for the entity;

comparing the current risk score of the user to historical risk scores to determine whether a risk score of a user has changed; and

changing the risk score of the user to the current risk score when the risk score of the user has changed.

2. The method of claim 1, wherein:

the endpoint comprises a risk-adaptive feature pack.

3. The method of claim 2, wherein:

the risk-adaptive feature pack comprises at least one of an event data detector module, an event data collector module and a risk-adaptive security policy

4. The method of claim 1, further comprising:

decreasing the duration of the endpoint monitoring interval when the current risk scores of the user decline over a plurality of endpoint monitoring intervals.

5. The method of claim 1, wherein:

decreasing the frequency of the endpoint monitoring interval when the current risk scores of the user remain substantially the same over a plurality of endpoint monitoring intervals.

6. The method of claim 1, wherein:

increasing the frequency of the endpoint monitoring interval when the current risk scores of the user increase over a plurality of endpoint monitoring intervals.

7. A system comprising:

a processor;

a data bus coupled to the processor; and

a non-transitory, computer-readable storage medium embodying computer program code, the non-transitory, computer-readable storage medium being coupled to the data bus, the computer program code interacting with a plurality of computer operations and comprising instructions executable by the processor and configured for;

determining a risk level corresponding to an entity associated with an endpoint;

selecting a frequency and a duration of an endpoint monitoring interval;

collecting user behavior associated with the entity for the duration of the endpoint monitoring interval via the endpoint;

processing the user behavior to generate a current risk score for the entity;

comparing the current risk score of the user to historical risk scores to determine whether a risk score of a user has changed; and

changing the risk score of the user to the current risk score when the risk score of the user has changed.

8. The system of claim 7, wherein:

the endpoint comprises a risk-adaptive feature pack.

9. The system of claim 8, wherein:

the risk-adaptive feature pack comprises at least one of an event data detector module, an event data collector module and a risk-adaptive security policy

10. The system of claim 7, wherein the instructions executable by the processor are further configured for:

decreasing the duration of the endpoint monitoring interval when the current risk scores of the user decline over a plurality of endpoint monitoring intervals.

11. The system of claim 7, wherein the instructions executable by the processor are further configured for:
