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.
