In an embodiment, an operating system is defined in terms of a set of actors, each of which implements one or more capabilities built into the system. The actors may establish channels between them for communication of messages between the actors. Some actors may interpose between other actors. These other actors may, in some cases, interpose on channels used by the base actor. In some embodiments, some channels may be interposed while others may be monitored by the interposing actor but may still communicate directly with the underlying actor. Some channels may not be affected by the interposition (e.g. the channels may not be interposed or monitored), in an embodiment. Other examples of interposition may include debugging, simulation, and sandboxing.

Interposition

A system and method wherein a set of privileges assigned to a process may be modified responsive to a request. The modification may apply to one or more abilities within the set of privileges and may be applied during execution of the process subsequent to the process creation time. Accordingly a process may be created with a default set of privileges and subsequently the privileges may be modified (e.g. to include a sub-set of the default privileges) thereby mitigating the risk of malicious exploitation of the process through attack.

System and method for changing abilities of a process

A method, apparatus and system for managing communications between a client machine and a mobile computing device. The mobile computing device comprising: a storage configured to maintain a host application; a processor configured to execute the host application; an interface configured to connect to the client machine, the interface further configured to carry a web request from the client machine to the processor, the host application configured to respond to the web request.
