Since nessusd (through many plugins) needs access to raw sockets,
bind low ports or sniff the traffic you have to run it under
root. (However, if your OS can grant chosen POSIX capabilities to
a process or a user/group, you can run nessusd under unprivilegged
user if it has CAP_NET_RAW, CAP_NET_BIND_SERVICE, CAP_NET_BROADCAST
and CAP_NET_ADMIN (?) capabilities.)
