Setting

ensures that access to process information is restricted to the
|
|
owning user. This implies, among other things, that command-line
|
|
arguments remain private. Unless your deployment relies on unprivileged
|
|
users being able to inspect the process information of other users, this
|
|
option should be safe to enable.
