4.9.7 DoS
The DoS is short for Denial of Service, which is a simple but effective destructive attack on the internet. The server under DoS
attack will drop normal user data packet due to non-stop processing the attacker’s data packet, leading to the denial of the
service and worse can lead to leak of sensitive data of the server.
Security feature refers to applications such as protocol check which is for protecting the server from attacks such as DoS. The
protocol check allows the user to drop matched packets based on specified conditions. The security features provide several
simple and effective protections against Dos attacks while acting no influence on the linear forwarding performance of the
switch.
4.9.7.1 Global DoS Setting
The Global DoS Setting and Information screens in Figure 4-9-44 and Figure 4-9-45 appear.
