Abstract
Various embodiments provide an ability to isolate execution of trusted content and/or script from execution of untrusted content and/or script. Separate contexts and/or execution environments can be used for the trusted content and untrusted content, respectively. A trusted context and/or execution environment associated with execution of trusted content can be configured to enable access to sensitive resources associated with a computing device. An untrusted context and/or execution environment associated with execution of untrusted content can be configured with limited and/or no access to the sensitive resources. Alternately or additionally, data generated within the untrusted context can be transferred to the trusted context in a benign manner.
