Abstract
Interprocess communication between processes that run on a host operating system of a computer is performed by way of a protected temporary file. File access operation on the temporary file is hooked to detect writing to the temporary file. When a process writes a message to the temporary file, a verification is performed to determine whether or not the process is authorized to access the temporary file. When the process is authorized to access the temporary file, the process is allowed to write the message to the temporary file. This allows another process that is intended to receive the message to read the message from the temporary file and act on the message. Otherwise, when the process is not authorized to access the temporary file, the process is blocked from writing the message to the temporary file.
