By using pipes or other transports made available to 1808 the process as file descriptors supporting the read/write 1809 syscalls, it's possible to isolate those applications in 1810 their own address space using seccomp. Once seccomp is 1811 enabled via /proc/<pid>/seccomp, it cannot be disabled 1812 and the task is only allowed to execute a few safe syscalls 1813 defined by each seccomp mode. 1814 1815 If unsure, say Y.
