How to Simulate Packet Flooding Attack Projects Using MATLAB

To simulate a packet flooding attack in MATLAB has includes to generating an in excess of traffic that goals at overcome a target node that is same as a Distributed Denial of Service (DDoS) attack. In this replication, attacker nodes create a high volume of packets to flood the network, triggers packet drops and upsurges the delay.

Below is the brief approach to simulate the basic packet flooding attack in MATLAB.

Steps to Simulate a Packet Flooding Attack

1. Define the Network Setup:
   • Setting up a network in which a target node (server) gets traffic from both appropriate clients and malevolent nodes.
   • Configure the key parameters like the target’s maximum packet handling capacity.
2. Simulate Normal and Attack Traffic:
   • Describe the packet generation rate for appropriate users.
   • Generate a considerable higher packet generation rate for the attacker nodes to replicate the flooding.
3. Monitor Performance Metrics:
   • Measure the parameters like packet drops, latency, and server load to learn the effects of the flooding attack.
   • Monitor on how much legitimate traffic is successfully handled when in the attack.
4. Visualize Results:
   • Utilize MATLAB plots to demonstrate the traffic patterns, focusing packet drops and overloading events.

Example Code for Packet Flooding Attack Simulation

% Parameters for Packet Flooding Attack Simulation

simulationTime = 60;         % Duration of the simulation in seconds

legitimateRate = 20;         % Packets per second from legitimate clients

numAttackers = 5;            % Number of attacking nodes

attackRate = 100;            % Packets per second per attacker

serverCapacity = 500;        % Maximum packets the server can handle per second

% Initialize Traffic Arrays

legitimateTraffic = legitimateRate * ones(simulationTime, 1); % Legitimate client traffic

attackTraffic = zeros(simulationTime, 1);

droppedPackets = zeros(simulationTime, 1);

% Simulate Attack Traffic Over Time

for t = 1:simulationTime

% Generate attack traffic from multiple attackers

attackTraffic(t) = numAttackers * attackRate;

% Total incoming traffic at the server

totalTraffic = legitimateTraffic(t) + attackTraffic(t);

% Check if the traffic exceeds server capacity

if totalTraffic > serverCapacity

% Calculate dropped packets

droppedPackets(t) = totalTraffic – serverCapacity;

disp([‘Time ‘ num2str(t) ‘s: Server is overwhelmed, dropping ‘ num2str(droppedPackets(t)) ‘ packets.’]);

legitimateTraffic(t) = max(serverCapacity – attackTraffic(t), 0); % Only part of legitimate traffic passes

else

droppedPackets(t) = 0; % No packet drop if within capacity

end

end

% Visualize Legitimate, Attack Traffic, and Dropped Packets

time = 1:simulationTime;

figure;

plot(time, legitimateTraffic, ‘-g’, ‘LineWidth’, 1.5, ‘DisplayName’, ‘Legitimate Traffic’);

hold on;

plot(time, attackTraffic, ‘-r’, ‘LineWidth’, 1.5, ‘DisplayName’, ‘Attack Traffic’);

plot(time, droppedPackets, ‘-k’, ‘LineWidth’, 1.5, ‘DisplayName’, ‘Dropped Packets’);

% Additional Analysis: Visualize Effective Traffic at Server

effectiveTraffic = min(legitimateTraffic + attackTraffic, serverCapacity);

plot(time, effectiveTraffic, ‘-b’, ‘LineWidth’, 1.5, ‘DisplayName’, ‘Effective Traffic at Server’);

ylabel(‘Traffic Volume (Packets per second)’);

Explanation of the Code

• Parameters:
  • legitimateRate denotes the packets per second created by legitimate clients.
  • numAttackers and attackRate describe the scale of the flooding threats.
  • serverCapacity is the target node’s maximum packet managing the capability.
• Traffic Simulation:
  • For each second, attackTraffic is created from attackers, since the legitimateTraffic denotes normal traffic.
  • totalTraffic is estimated by incorporating legitimate and attack traffic. If it surpasses serverCapacity, packets are dropped.
• Packet Drop Calculation:
  • When totalTraffic surpasses serverCapacity, the difference is deliberated dropped packets.
  • Only a portion of legitimateTraffic can travel via uncertainty the server is overloaded.
• Visualization:
  • Plot appropriate, attack, and released packets to demonstrate on how the server is impacted by the flooding.
  • The efficient traffic plot illustrates the volume of packets the server effectively processes.

Analysis and Extension Ideas

• Latency Simulation: Incorporate latency metric to replicate increased delay because of high traffic load.
• Defense Mechanisms: Execute simple defence mechanisms such as rate limitation or traffic extracting in the replication.
• Dynamic Attack Patterns: Adjust the attack rate enthusiastically over time to implement real-world attack features.
• Advanced Detection: Incorporate anomaly detection techniques to find the unusual traffic patterns according to traffic volume.
