Abstract

An inter-process messaging security management may be provided. A message comprising an operation to be performed may be sent from a process operating in a process chamber to a second process operating in another chamber. Before the message is allowed to be delivered, the validity of the operation contained in the message may be verified and a security policy may be examined to determine whether the message is permitted to be sent from the first process to the second process. If the security policy permits the second process to execute the operation requested by the first process, the message may be delivered to the second process. If the operation is not permitted, the message may not be delivered and an error message may be returned to the first process.
