How to Implement ddos Attack in OMNeT++

To implement a DDoS (Distributed Denial of Service) attack in OMNeT++ requires a network simulation that replicates the characteristics of DDoS attack and its influence on the network by creating one. Below, we offered the step-by-step approach to implement it:

Step-by-Step Implementation:

1. Set Up OMNeT++ and INET Framework

• Make certain to install the OMNeT++ and the INET framework and properly configured on your system.
• For simulating networks, we use the INET framework that offers modules and protocols which you’ll need for the DDoS attack simulation.

2. Define the Network Topology

• To state the nodes, we need to generate the network topology in OMNeT++ (for example: servers, routers, and clients).
• In the .ned file, certain the types of nodes (e.g., hosts and routers) and how they are linked.

Example:

network DDoSNetwork

{

submodules:

server: StandardHost;

attacker1: StandardHost;

attacker2: StandardHost;

router: Router;

connections:

attacker1.ethg++ <–> Eth10G <–> router.ethg++;

attacker2.ethg++ <–> Eth10G <–> router.ethg++;

router.ethg++ <–> Eth10G <–> server.ethg++;

}

3. Configure the Attacker Nodes

• Generate malicious traffic by describing the attacker nodes. These nodes should be configured to send a high volume of packets to the target server.
• Build the parameters for the attack traffic in the .ini configuration file. (like packet size, sending rate).

Example:

*.attacker1.app[0].typename = “UdpBasicApp”

*.attacker1.app[0].destAddress = “server”

*.attacker1.app[0].destPort = 80

*.attacker1.app[0].messageLength = 1024

*.attacker1.app[0].sendInterval = exponential(0.01s)

*.attacker2.app[0].typename = “UdpBasicApp”

*.attacker2.app[0].destAddress = “server”

*.attacker2.app[0].destPort = 80

*.attacker2.app[0].messageLength = 1024

*.attacker2.app[0].sendInterval = exponential(0.01s)

4. Configure the Server Node

• Set up the server node to receive and process incoming traffic. Monitoring how the server manages the DDoS attack by define the logging. When the server becomes overwhelmed because of drop packets, it simulates the impact of a DDoS attack.

Example:

*.server.app[0].typename = “UdpSink”

*.server.app[0].localPort = 80

5. Run the Simulation

• Compile the OMNeT++ project and run the simulation.
• Monitor the actions of the network, especially how the server reacts to the incoming flood of traffic from the attackers.

6. Analyze the Results

• Learn the effect of the DDos attack by using the analysis tool of OMNeT++. See the metrics like its packet loss, server response time, and network throughput.
• Use in-built OMNeT++ tools to visualize the traffic or export the results for further analysis.

7. Enhancements and Variations

• Adding more attacker nodes, changing attack traffic or executing defence mechanisms includes rate limiting or firewalls to expand the simulation.
• Altering the actions of attacker to contemplate simulating various kinds of DDoS attacks like SYN flood or UDP flood.

Example Files

We might create the following files as part of the simulation:

• DDoSNetwork.ned: Configure the network topology.
• omnetpp.ini: Contains configuration settings such as parameters for the DDoS attack.
• DDoSNetwork.cc: (Optional) Custom C++ code if you need more advanced behavior than what is provided by the standard INET modules.

Finally, this demonstration gives you the general steps create a simulation which help us to implement the DDoS attack in the OMNeT++ environment. If you have any queries about this approach, we will guide you.
