Runtime risk detection based on user, application, and system action sequence correlation

A method for assessing runtime risk for an application program that executes on a device, comprising:

• storing, in a rules database, a plurality of rules, wherein each rule identifies an action sequence;
• storing, in a policy database, a plurality of assessment policies, wherein each assessment policy includes at least one rule of the plurality of rules;
• identifying, using at least one assessment policy, a runtime risk for an application program that executes on a device, wherein the identified runtime risk indicates a risk or threat of the identified action sequence of the application;
• and
• identifying, by a runtime monitor including a processing device, a behavior score for the application program that executes on the device based on the identified runtime risk, wherein
• the action sequence is a sequence of at least two performed actions, and
• each performed action is at least one of:
• a user action, an application action, and a system action.
