9.8 DoS (Denial of Service)

SL-600/SL6300 is able to protect your network against the following attacks

by proper configuration in this page (Figure 9.8)

9.8.1 SYN Flooding Attack Check

This attack involves sending connection requests to a server, but never fully

completing the connections. This will cause some computers to get into a “stuck

state” where they cannot accept connections from legitimate users. (“SYN” is

short for “SYNchronize”; this is the first step in opening an Internet connection).

You can select this box if you wish to protect the network from TCP Syn flooding.

9.8.2 Winnuke Attack Check

Certain older versions of the MS Windows OS are vulnerable to this attack. If

the computers in the LAN are not updated with recent versions/patches, you

are advised to enable this protection by checking the check box.

9.8.3 MIME Flood Attack Check

You can select this box to protect the mail server in your network against MIME

flooding.
