To simulate the network attacks using MATLAB that permits us to know the vulnerabilities and experiment the defense mechanisms within a controlled environment. MATLAB tool can replicate several network attacks like Denial of Service (DoS/DDoS), Man-in-the-Middle (MITM), Spoofing, and Eavesdropping, in addition to security mechanisms, which protect versus these attacks.
Let’s see how to simulate diverse kinds of network attacks using MATLAB:
Steps to Simulate Network Attacks Projects in MATLAB
- Select the Network Attack Type
To replicate, we can select on the kind of network attack. General network attack kinds contain:
- Denial of Service (DoS/DDoS): Excess a server with requests.
- Man-in-the-Middle (MITM): Intercept and probably change the communications amongst two parties.
- IP Spoofing: Transmit packets with a forged sender address.
- Packet Sniffing/Eavesdropping: Apprehend the network packets for analysis.
- Simulating a Denial of Service (DoS/DDoS) Attack
A DoS or DDoS attack floods a network including excessive traffic, using server resources and to create it unavailable to the legitimate users.
Example: Simple DDoS Attack Simulation
% Parameters for DDoS attack
numAttackers = 100; % Number of attackers
trafficRate = randi([50, 100], numAttackers, 1); % Traffic rate from each attacker (packets/sec)
% Server capacity
serverCapacity = 500; % Maximum packets the server can handle per second
% Simulate DDoS traffic from all attackers
totalTraffic = sum(trafficRate); % Total traffic from attackers
disp([‘Total traffic generated by attackers: ‘, num2str(totalTraffic), ‘ packets/sec’]);
% Check if the server can handle the traffic
if totalTraffic > serverCapacity
disp(‘DDoS attack successful: Server is overwhelmed.’);
else
disp(‘Server is handling the traffic without issues.’);
end
Enhancing the DoS Simulation:
- Change the attack rate over time to replicate a maximizing load.
- Replicate several targets being attacked concurrently.
- Examine the influence on network latency, throughput, or packet loss for the period of the attack.
- Simulating a Man-in-the-Middle (MITM) Attack
A MITM attack intercepts communication amongst two parties, which permitting the attacker to interpret or change the sent data.
Example: MITM Attack on a Simple Message Transmission
% Simulate communication between Alice and Bob
messageFromAlice = ‘Hello Bob, this is Alice’; % Original message
% Man-in-the-Middle attack (interception)
attackerInterceptedMessage = messageFromAlice;
disp([‘Attacker intercepted the message: ‘, attackerInterceptedMessage]);
% Attacker modifies the message
modifiedMessage = ‘Hello Bob, this is Attacker’;
disp([‘Attacker sent modified message: ‘, modifiedMessage]);
% Bob receives the modified message
messageToBob = modifiedMessage;
disp([‘Bob received the message: ‘, messageToBob]);
In this case, we can insert the encryption to the interaction and experiment how encryption avoids effective MITM attacks.
- Simulating IP Spoofing
IP spoofing includes transmitting packets along with a forged IP address to conceal the attacker’s identity. It is generally utilized within DoS attacks to avoid monitoring the attacker.
Example: Simulating IP Spoofing in Packet Transmission
% Define legitimate sender and receiver IPs
legitimateSenderIP = ‘192.168.1.2’;
receiverIP = ‘192.168.1.5’;
% Attacker spoofs sender IP
attackerIP = ‘192.168.1.100’; % Attacker’s real IP
spoofedIP = legitimateSenderIP; % Attacker forges the legitimate sender’s IP
% Attacker sends a spoofed packet
disp([‘Attacker (real IP: ‘, attackerIP, ‘) sends packet with spoofed IP: ‘, spoofedIP]);
% Receiver believes the packet came from the legitimate sender
disp([‘Receiver (IP: ‘, receiverIP, ‘) receives packet from spoofed IP: ‘, spoofedIP]);
Enhancements:
- Execute the IP filtering mechanisms to identify spoofed packets.
- Replicate the use of firewalls or packet inspection systems to relieve IP spoofing attacks.
- Simulating Packet Sniffing (Eavesdropping)
Packet sniffing encompasses the intercepting and reading data sent through the network. We can mimic an eavesdropper apprehending network packets within a wireless or wired network.
Example: Simulating Packet Sniffing
% Simulate a series of network packets sent by a user
userPackets = {‘Packet 1: Hello’, ‘Packet 2: This is a test’, ‘Packet 3: Good bye’};
% Attacker captures the packets
for i = 1:length(userPackets)
capturedPacket = userPackets{i};
disp([‘Attacker captured: ‘, capturedPacket]);
end
- Simulating ARP Spoofing Attack
ARP spoofing (or ARP poisoning) is an attack in which the attacker transmits the false ARP messages to connect its MAC address with the IP address of other node on the network.
Example: ARP Spoofing Simulation
% Legitimate IP to MAC mappings in ARP cache
arpCache = containers.Map({‘192.168.1.2’, ‘192.168.1.3’}, {‘AA:BB:CC:DD:EE:01’, ‘AA:BB:CC:DD:EE:02’});
% Attacker’s fake ARP message
attackerIP = ‘192.168.1.2’;
attackerMAC = ‘AA:BB:CC:DD:EE:99’;
% Attacker poisons the ARP cache
arpCache(attackerIP) = attackerMAC;
% Display the ARP cache after attack
disp(‘ARP cache after spoofing:’);
disp(arpCache);
Enhancements:
- Replicate the defense mechanisms such as ARP spoofing detection tools or DHCP snooping to avoid the ARP poisoning.
- Simulating Replay Attacks
A replay attack is once an attacker intercepts an interaction session and later resends the similar packets to acquire unauthorized access or disrupt operations.
Example: Simulating a Replay Attack
% Original packet sent by the legitimate user
legitimatePacket = ‘Login: user1, Password: 1234’;
% Attacker intercepts and stores the packet
attackerStoredPacket = legitimatePacket;
disp([‘Attacker stored packet: ‘, attackerStoredPacket]);
% Attacker replays the stored packet to gain access
disp([‘Attacker replays the stored packet: ‘, attackerStoredPacket]);
- Visualizing Attack Effects
Envision the network performance degradation by reason of attacks by using MATLAB’s powerful plotting tools.
Example: Visualizing Traffic During DDoS Attack
% Simulate network traffic under attack and normal conditions
time = 0:0.1:10; % Time vector (in seconds)
normalTraffic = 50 * ones(size(time)); % Normal traffic rate (50 packets/sec)
attackTraffic = normalTraffic + 200 * (time > 5); % Attack starts at t = 5 seconds
% Plot network traffic over time
figure;
plot(time, normalTraffic, ‘g’, ‘DisplayName’, ‘Normal Traffic’);
hold on;
plot(time, attackTraffic, ‘r’, ‘DisplayName’, ‘Traffic During Attack’);
xlabel(‘Time (s)’);
ylabel(‘Traffic (Packets/sec)’);

- Combining Multiple Attack Types
We can replicate the situation in which numerous attack types happen concurrently such as DDoS combined with IP Spoofing, which creating the simulation more realistic and challenging.
Example Projects for Network Attack Simulation in MATLAB:
- Simulating DDoS Attacks: Make a network of attacking nodes, which devastate a target server that replicating either effective or mitigated attacks utilizing the rate limiting or firewall rules.
- Intrusion Detection System (IDS): Aggregate the attack simulations (DDoS, MITM, and Spoofing) with anomaly detection with the help of machine learning or statistical methods.
- Simulating MITM Attacks in Encrypted Networks: Mimic a MITM attack along with encryption, and then estimate how successfully encryption algorithms defend the data.
- Detecting and Preventing ARP Spoofing: Replicate an ARP spoofing attack and execute the detection methods like verifying IP-MAC mappings or observing the network behavior.
- Wireless Network Security and Eavesdropping Simulation: Under eavesdropping attacks, replicate wireless networks and discover encryption mechanisms like WPA/WPA2 to relieve such attacks.
