Abstract

A method to identify a child process to a parent process in an operating system includes obtaining a token and login identifier from the operating system. The parent process creates a remote procedure call communications endpoint to communicate with the child process. Thereafter, a child process is spawned by the parent process. A child-initiated request to communicate with the parent process is then received by the parent process. In order to verify the identity of the child-initiated request, the parent process impersonates the child process and receives as identifier that identifies the requestor child process. The requestor process identifier and the spawned child identifier are compared. Based on the comparison, the parent process responds to the child-initiated request. In another embodiment, process identifiers are used by the parent process to verify the identity of a child process the requests communication with the parent process.

First claim

What is claimed:

1. A computer readable storage device storing thereon computer readable instructions for identifying a child process to a parent process, comprising:
instructions for creating a communications endpoint;
instructions for spawning, by the parent process, the child process and passing the communications endpoint to the child process, the child process having a child security identifier;
instructions for receiving a request to communicate with the parent process,…
