NESSUS reported that ports 22 (SSH), 23 (TELNET), 443 (HTTPS) and 6789 (SMC-HTTPS? HDD-TEMP Server? a Worm?) were found on a WatchGuard FireBox V60 5.1.2.
Are these ports necessary to manage the Firebox itself? If some of them are unnecessary, how can one disable them.
Any pointers are appreciated.
Thanks,
DF
