Preventing others to access my process via interprocess communication

[Marco2250]

Hi all. How I prevent others to access my process via interprocess communication? I know that when I want to open a process using IPC I can use OpenProcess function and inform the desired access. How I can prevent every access, i.e., no PROCESS_VM_READ access, no PROCESS_VM_WRITE acess, etc etc. And, How i can deny ipc access for all process but allow it to a specif process? Thx in advance. Best regards, Marco Alves.

First, the process access as you described is not IPC. It's usually controlled by process's security attributes. You may call SetSecurityInfo() to define security of a process. Hope this link can help. On the other hand, IPC is the communication between two processes. Thus, it's mutual. If your process does not respond to IPC, nobody can do anything to hurt it.
