DDoS Attack Defense Policy

Latest reply: Feb 6, 2020 07:42:52 182 4 5 0

Hello, everyone!

This post describes how to configure DDoS attack defense policy on the switches.

1 Problem Description  

1.1 DDoS Overview  

Distributed Denial of Service (DDoS) attacks exploit the defects in the network service function of the target system or directly consume the system resources of the target system. As a result, the target system cannot provide normal services. There are many types of DDoS attacks. The basic DoS attack is to use reasonable service requests to occupy too many service resources so that authorized users cannot obtain service responses.   


1.2 Problem Description  

DDoS attacks occur on the network, causing interruption of downstream HMS media services and affecting the HMS service rollout plan.  The firewall on the network is a third-party device, which has insufficient capabilities.  We need to configure anti-DDoS on the switch. The following figure shows the networking.

2. Attack Defense Solution

 Based on the service conditions on the live network, bypass the services that are normally interconnected and discard other traffic.  

3. Anti-attack deployment verification  

3.1 Environment Setup

3.2 Configuration Deployment

 Deploy the solution on S12708-1.

Applied to the VLAN

DDoS Attack Defense Policy-3206600-7

3.3 Solution Verification 

Use the tester to send simulated packets that match rule 60.  

DDoS Attack Defense Policy-3206600-8

DDoS Attack Defense Policy-3206600-9

The preceding information shows that the packets matching the rule are permitted and the packets not matching the rule are discarded. This effectively prevents DDoS attacks.


 This is a case about DDoS attack defense, I hope it is of help to you.
