Security Context Lockdown

One or more computer-readable storage media storing computer-executable instructions that, when executed by a computing device, cause the computing device to perform operations comprising:

• implementing a security context for rendering of content by an application with elevated privileges, the security context associated with default configuration settings defining the elevated privileges and alternate lockdown configuration settings to place increased restrictions on content when a lockdown mode is activated for the security context;
• and
• when the lockdown mode is activated, locking down the security context to implement the increased restrictions for the content by returning the alternate lockdown configuration settings instead of the default configuration settings for use by the application to render the content.
