4.9.11 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.
