Port Scan
Some malicious intruder will try to use a ‘port scanner’ to
detect how many ports of your Internet IP address are
open. Check this box and BR-6479Gn will block all
traffics which are trying to scan your Internet IP address.
Sync Flood
This is another kind of attack, which uses a lot of fake
connection request to occupy the memory of your server,
and try to make your server become unusable. Check
this box and BR-6479Gn will filter this kind of traffic out.
