Overview

Denial of Service Attack Protection

This section describes the D-Link DWS-3000 switch’s Denial of Service Protection feature.

Overview

Denial of Service:

•

Spans two categories:

Protection of the Unified Switch

Protection of the network

•

Protects against the exploitation of a number of vulnerabilities which would make the host
or network unstable

•

Compliant with Nessus. Nessus is a widely-used vulnerability assessment tool.

•

The Unified Switch provides a number of features that help a network administrator pro-
tect networks against DoS attacks.

CLI Examples

Enter from Global Config mode:

(DWS-3024) #configure

(DWS-3024) (Config)#dos-control sipdip

(DWS-3024) (Config)#dos-control firstfrag

(DWS-3024) (Config)#dos-control tcpfrag

(DWS-3024) (Config)#dos-control l4port

(DWS-3024) (Config)#dos-control icmp

(DWS-3024) (Config)#exit

(DWS-3024) #show dos-control
