By using pipes or other transports made available to 1832 the process as file descriptors supporting the read/write 1833 syscalls, it's possible to isolate those applications in 1834 their own address space using seccomp. Once seccomp is 1835 enabled via /proc/<pid>/seccomp, it cannot be disabled 1836 and the task is only allowed to execute a few safe syscalls 1837 defined by each seccomp mode. 1838 1839 If unsure, say Y.
