Method and system for merging security policies

摘要

A method and system for combining and enforcing security policies is provided. The security system is provided with security policies that have process set criteria and associated rules. The security system combines the security policies by generating a rule list of the security policies and associated process set criteria. The rules of the rule list are ordered based on rule type and action of the rule. When a new process is started to execute an application, the security system determines the process set criteria that are satisfied by the application. The security system then identifies the rules of the rule list that are associated with the satisfied process set criteria. When a security enforcement event associated with the process occurs, the security system applies each of the rules associated with the process to the security enforcement event in an order specified by the rule list.
