With ACL rules we can protect ports and/or IP addresses from hostile traffic.
This makes it possible to for example only allow SSH access for a particular set of IP addresses.
With rate limiting we can protect your server from for exampe HTTP floods.
It is possible to for example limit the incoming connections from one IP address to 5 per second.
A SYN flood is a attack in which a attacker creates half opened connections. Use quantities of this can cause your server to deny access to legitimate traffic.
With SYN flood protection we can stop these kinds of attacks at the edige of our network.
