Secure Runtime Execution of Web Script Content on a Client

摘要

Method for ensuring security of online content on a client device. Online content is rendered on a display on the client device and the client device stores one or more policies each defining an execution boundary of a web script content. The execution boundary defines resource access of the web script content, and the web script content is configured to issue an execution invocation to interact with other portions of the online content. The issued execution invocation is intercepted and parameters included in the intercepted execution invocation are identified. The identified parameters request resources from an application or the client device for interacting with the other portions of the online content. The identified parameters are evaluated against the execution boundary of each of the policies stored in the client device. A dynamic resolution is provided to the web script content in response to the evaluating.
