Methods and systems for sharing a security model with heterogeneous virtual machines (VMs) are provided. A method for sharing a security model with heterogeneous VMs may include making a direct function call to an object model from each of two or more heterogeneous VMs using a direct binding generated for the respective VM based on the respective VM and a security policy. The direct bindings of the two or more heterogeneous VMs share the security policy. The method may also include ensuring only one of the two or more heterogeneous VMs interacts with the object model at a time. A system for sharing a security model with heterogeneous VMs may include a heterogeneous VM manager and a heterogeneous VM scheduler. The system may further include a principal tracker and a proxy component.

Heterogeneous virtual machines sharing a security model

Systems, methods and articles of manufacture for process-based domain isolation are discussed herein. A method embodiment includes determining domains associated with a plurality of content areas and rendering content areas associated with different domains into separate processes, wherein each domain from the one or more domains is associated with a separate process that communicates with its respective individual domain. The method further comprises identifying browsing instances including content areas that can script each other, identifying site instances including content areas sharing a common domain, and controlling communication between content areas across the identified site instances within each browsing instance.

Process-based domain isolation

A safe environment is established for running untrusted code in a system whose trusted libraries include native code. Annotations are applied to code in the system libraries to identify safe and unsafe code, and analysis tools reveal whether code outside the system libraries is able to trigger any unsafe behavior.
