By using pipes or other transports made available to 1802 the process as file descriptors supporting the read/write 1803 syscalls, it's possible to isolate those applications in 1804 their own address space using seccomp. Once seccomp is 1805 enabled via /proc/<pid>/seccomp, it cannot be disabled 1806 and the task is only allowed to execute a few safe syscalls 1807 defined by each seccomp mode. 1808 1809 If unsure, say Y.
