How to Start DDoS Projects Using OMNeT++

To create a DDoS (Distributed Denial of Service) attack replication for the project in OMNeT++ ha involves a generating the network situations in which the several nodes perform as an attackers, overwhelming a victim node or service by congestion. This can help examine the attack’s effect and create the mitigation techniques. Here’s a step-by-step guide to following based on this procedure:

Steps to Start DDoS Projects Using OMNeT++

  1. Set up Your Environment
  • Install OMNeT++:
    • Download OMNeT++ from the official website.
    • Install the latest fixed version, such as OMNeT++ 6.x.
  • Install INET Framework:
    • Download the INET Framework from its GitHub repository.
    • Generate the INET Framework in OMNeT++.
  1. Understand DDoS Attack Mechanics
  • In a DDoS attack, multiple malicious nodes (bots) send overwhelming number of congestion to a goal, for exhausting its resources
  • General the DDoS kinds for the involves they are:
    • UDP Flood: Increase the volume for transmitting the UDP packets.
    • TCP SYN Flood: Manipulating the TCP handshake process for the TCP SYN flood.
    • HTTP Flood: Forwarding the excessive for HTTP requests to overcome a server.
  1. Design Your Network Topology
  • State a network architecture:
    • Nodes: it involves the legitimate clients, attacker nodes, and the victim for the node.
    • Traffic: Setting the legitimate and malicious congestion flows for the architecture.
  • Example topology:
    • Legitimate clients: Create congestion for general is legitimate the clients.
    • Attackers (bots): Flood the victim through malicious congestion.
    • Victim: The server or service receipts the attack for a victim.
  1. Create or Modify Modules
  • Victim Node:
    • Used a previous server module for the victim node for sample inet.applications.tcpapp.TcpServerApp.
    • Setting the victim we maintain the legitimate traffic.
  • Attacker Nodes:
    • Build a modify DDoS attacker components through alter acongestion generator for instance inet.applications.udpapp.UdpBasicApp.
    • Apply the logic we transmit the malicious congestion at increase the rates.

Example attacker code (pseudo):

class DDoSAttacker : public inet::UdpBasicApp {

protected:

virtual void handleTimer(cMessage *msg) override {

// Generate malicious packets

auto packet = createPacket(“MaliciousPacket”);

sendPacket(packet);

scheduleAt(simTime() + par(“attackInterval”), msg);

}

};

  1. Configure the Simulation
  • Network Configuration (.ini file):
    • State the total of legitimate clients, attackers, and the victim for network setting.
    • Set-up the congestion parameters metrices for every node.

Example configuration:

[Config DDoS_Simulation]

network = DDoSNetwork

sim-time-limit = 100s

# Legitimate clients

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

*.client[*].app[0].destAddresses = “victim”

*.client[*].app[0].messageLength = 512B

*.client[*].app[0].sendInterval = uniform(0.1s, 0.2s)

# Attacker nodes

*.attacker[*].app[0].typename = “DDoSAttacker”

*.attacker[*].app[0].destAddresses = “victim”

*.attacker[*].app[0].messageLength = 512B

*.attacker[*].app[0].sendInterval = uniform(0.001s, 0.005s)

# Victim server

*.victim.app[0].typename = “TcpServerApp”

  1. Run the Simulation
  • Open the OMNeT++ IDE and replication for the processing.
  • Observe network behavior:
    • We track the congestion flows.
    • Classify on how the victim maintain the legitimate against malicious congestion.
  1. Analyze the Results
  • Metrics to evaluate:
    • Throughput: Calculate the legitimate and malicious congestion rates.
    • Packet Loss: Checked on how many legitimate packets are stopped in the packet loss.
    • Server Response Time: examine the delay for below the attack.
    • CPU/Memory Usage: Estimate the victim’s resource usage for the CPU consumption.
  • Used the outcomes for OMNeT++ tools we make a graphs and logs.
  1. Enhance the Simulation (Optional)
  • Implement DDoS Mitigation:
    • Improve the rate-limiting mechanisms on the victim.
    • Apply the Intrusion Detection System (IDS) we block the attackers.
  • Experiment with Attack Variants:
    • Validate the various attack of DDoS methods for sample TCP SYN flood, HTTP flood.
  • Simulate Large-Scale Attacks:
    • Used a further general network through distributed the bots for large scale networks.
  1. Visualize and Document Results
  • Used envision for OMNeT++ we replicate the outcomes for visualization.
  • Document:
    • We configure the attacks and parameters metrices.
    • Network performance is impacted.
    • Efficiency of mitigation methods.

Finally, we had effectively distributed the significant procedures to simulate the Distributed Denial of Service in OMNeT++ tool and also we deliver the sample snippets and their explanation. Further data about Distributed Denial of Service will be shared in upcoming manual.
