4. The method of claim 1 , wherein assessing, by the hardware processor, cloud service usage behavior and pattern of the enterprise comprises:

receiving, by the hardware processor, network event data from a data network associated with the enterprise, the network event data relating to network data traffic between the data network and the one or more cloud service providers;

correlating, by the hardware processor, network event data to the one or more cloud service providers; and

generating, by the hardware processor, one or more cloud service usage analytics based on the network event data and the cloud service provider information.

5. The method of claim 1 , wherein generating a user risk score further comprises:

generating, by the hardware processor, the user risk score associated with the cloud service usage behavior and pattern belonging to one or more users of the enterprise and the darknet intelligence attribute associated with the one or more users, the darknet intelligence attribute comprising darknet intelligence data indicating whether user credentials associated with the one or more users have been compromised.

6. The method of claim 5 , further comprising:

determining, by the hardware processor, a user risk score for a first user exceeding a first threshold; and

generating, by the hardware processor, a recommendation to the enterprise to change the user credential of the first user.

7. The method of claim 1 , further comprising:

generating an N-day average enterprise risk score using the enterprise risk score;

comparing the enterprise risk score at a given time interval to the N-day average enterprise risk score;

detecting the enterprise risk score at a given time interval exceeding the N-day average enterprise risk score by a predetermined limit value; and

generating an alert for the enterprise in response to the detecting.

8. The method of claim 7 , further comprising:

generating an N-day average user risk score using the user risk score;

comparing the user risk score at a given time interval to the N-day average user risk score;

detecting the user risk score at a given time interval exceeding the N-day average user risk score by a predetermined limit value; and

generating an alert for the enterprise in response to the detecting.

9. The method of claim 7 , further comprising:

generating an N-day average enterprise risk score using the enterprise risk score;

comparing the user risk score at a given time interval to the N-day average enterprise risk score;

detecting the user risk score at a given time interval exceeding the N-day average enterprise risk score by a predetermined limit value; and
