To simulate active attacks using MATLAB tool that encompasses to make designs of aggressive network behaviors like packet modification, insertion, deletion, or impersonation. Active attacks can be contained Denial of Service (DoS), Man-in-the-Middle (MITM), Session Hijacking, and Replay attacks. Follow the provided guide to simulate the numerous kinds of active attacks within MATLAB.
General Steps for Simulating Active Attacks
- Define the Network and Attack Environment
- Configure a network model along with nodes that denoting clients, servers, and probably an attacker node.
- Indicate the typical traffic patterns and usual communication protocols to show a baseline.
- Simulate Attack Scenarios
- Select the type of active attack and set up metrics like packet rate, attack duration, and target nodes.
- For instance, in a MITM attack, the attacker node be able to intercept, alter, and forward packets amongst nodes.
- Monitor Impact on Network Performance
- To monitor how the network performances under attack conditions, we can observe performance parameters such as latency, throughput, packet loss, and error rates.
- Envision network performance parameters to show the effect of attack.
- Implement Detection or Defense Mechanisms (Optional)
- Replicate the intrusion prevention systems or intrusion detection, which recognize and mitigate attack patterns.
Example Code for Different Types of Active Attacks
- Man-in-the-Middle (MITM) Attack Simulation
In a MITM simulation, the attacker intersects and potentially changes the packets among two communicating nodes.
% Network and Attack Parameters
numNodes = 3; % Node 1: Sender, Node 2: Receiver, Node 3: Attacker
simulationTime = 50; % seconds
packetRate = 5; % Packets per second from sender to receiver
mitmStartTime = 10; % Start MITM attack at second 10
mitmEndTime = 40; % End MITM attack at second 40
% Simulating Traffic
traffic = zeros(simulationTime, numNodes);
for t = 1:simulationTime
% Sender sends packets at regular intervals
if t <= mitmStartTime || t > mitmEndTime
% Normal traffic from Node 1 to Node 2
traffic(t, 1) = packetRate; % Sender
traffic(t, 2) = packetRate; % Receiver receives packets
else
% MITM attack: Attacker intercepts and modifies packets
traffic(t, 1) = packetRate; % Sender
traffic(t, 3) = packetRate; % Attacker intercepts
traffic(t, 2) = packetRate * 0.5; % Receiver receives altered packets
disp([‘Time ‘ num2str(t) ‘: MITM active, attacker intercepting traffic.’]);
end
end
% Visualizing Traffic
time = 1:simulationTime;
figure;
plot(time, traffic(:, 1), ‘-b’, ‘DisplayName’, ‘Sender Traffic’);
hold on;
plot(time, traffic(:, 2), ‘-g’, ‘DisplayName’, ‘Receiver Traffic’);
plot(time, traffic(:, 3), ‘-r’, ‘DisplayName’, ‘Attacker Intercepted Traffic’);

- Denial of Service (DoS) Attack Simulation
An attacker transmits the high traffic to devastate a target that triggering legitimate packets to drop in a DoS attack.
% DoS Attack Parameters
numAttackers = 10; % Number of attacking nodes
attackRate = 100; % Attack packets per second per attacker
legitimateTrafficRate = 20; % Normal legitimate traffic to the server
serverCapacity = 500; % Maximum capacity of packets per second
% Simulating Attack Traffic
dosTraffic = zeros(simulationTime, 1);
legitimateTraffic = legitimateTrafficRate * ones(simulationTime, 1);
for t = 1:simulationTime
% Attack traffic from multiple attackers
dosTraffic(t) = numAttackers * attackRate;
% Total incoming traffic at the server
totalTraffic = dosTraffic(t) + legitimateTraffic(t);
% Server handling capacity and packet drops
if totalTraffic > serverCapacity
disp([‘Time ‘ num2str(t) ‘s: Server overwhelmed!’]);
legitimateTraffic(t) = max(serverCapacity – dosTraffic(t), 0); % Only some legitimate traffic passes
end
end
% Visualizing Traffic Impact
figure;
plot(time, dosTraffic, ‘-r’, ‘DisplayName’, ‘DoS Attack Traffic’);
hold on;
plot(time, legitimateTraffic, ‘-g’, ‘DisplayName’, ‘Legitimate Traffic After Attack’);

- Replay Attack Simulation
In a replay attack, an attacker forwards again packets to a target to trigger mistakes or duplicate actions.
% Replay Attack Parameters
originalPacketRate = 10; % Original packet rate from sender to receiver
replayStartTime = 15; % Replay attack starts at second 15
replayDuration = 20; % Duration of the replay attack
replayPacketRate = originalPacketRate; % Same packet rate as original traffic
% Simulate Traffic and Replay Attack
replayTraffic = zeros(simulationTime, 1);
originalTraffic = originalPacketRate * ones(simulationTime, 1);
for t = replayStartTime:(replayStartTime + replayDuration)
replayTraffic(t) = replayPacketRate;
disp([‘Time ‘ num2str(t) ‘s: Replay attack active, duplicating packets.’]);
end
% Total Traffic During Attack
totalTraffic = originalTraffic + replayTraffic;
% Visualization of Replay Attack
figure;
plot(time, originalTraffic, ‘-b’, ‘DisplayName’, ‘Original Traffic’);
hold on;
plot(time, replayTraffic, ‘-r’, ‘DisplayName’, ‘Replay Attack Traffic’);
plot(time, totalTraffic, ‘-k’, ‘DisplayName’, ‘Total Traffic with Replay’);

Analysis and Extension
- Latency Increase: Monitor and envision latency that particularly in DoS attacks.
- Packet Loss: Compute packet loss rates by reason of dropped packets for the period of high traffic.
- Error Detection: Incorporate error-checking mechanisms for MITM or replay attacks, which replicating preventions responses and detection.
