If I have some sensitive data to transfer between two processes, I can create a named FIFO in /tmp and delete it after use. I want to know if this method secure? How easy will it be to break the FIFO?
I know there are several ways to perform IPC(inter-processes communication), but IMHO, pipe is not ideal since it sometimes left buffered data on harddisk; shared memory is secure but not alwasy feasible.
