To Simulate the intrusion attacks in MATLAB has been contains the configuration of environment network, and executing the thread environment and it determining the effects. Below the brief procedure to simulate the intrusion attacks and it impact the evaluating their network analysing system.
Steps to Simulate Intrusion Attacks in MATLAB
- Define the Network Environment
- The simple network environment established the multiple nodes instead of a devices and routers or servers.
- To utilizing the random node placement for specific topology and it signifies to replicate the network or predefined places.
- The regular traffic flow to create the protocols for communication such as packet transmission among nodes.
- Choose Types of Intrusion Attacks Common intrusion attacks include:
- Denial of Service (DoS): The network services are unreachable to create the request to overcome the network services.
- Man-in-the-Middle (MitM): It interrupts the interactions among access the two nodes or modify the data.
- Packet Sniffing: Interrupts the data packets to gathering the complex data.
- SQL Injection: Exploits susceptibilities by inserting the SQL queries for web-based replications.
- Brute Force: For attempts the multiple passwords to trying the unauthorised access before authentication attributes.
- Implement the Attack Models
- Model every attack category as a separate function or script, that generates the disturbing events beside the network
- Example: The DoS attack could be replicated to creating the extreme data packets to concern the specific node.
- Set Up Performance Metrics Measure the following to analyse the attack’s impact:
- Throughput: To verify the amount of effective message distribution.
- Packet Loss: To evaluate the number of packets misplaced because of the threats.
- Latency: Estimate the latency produced by the assaults.
- Energy Consumption: Designed the wireless network to access the extra power usage because of them malevolent performance.
Example MATLAB Code for Simulating a DoS Attack
The Dos attack replicate anywhere from one node that guides to extreme number of requests to a direct node for network performance effects.
% Parameters
numNodes = 20; % Total number of nodes in the network
targetNode = 5; % Node targeted by the DoS attack
attackNode = numNodes; % Node used as the attacker
normalPacketRate = 1; % Normal packet sending rate
attackPacketRate = 50; % Packet rate during the DoS attack
% Initialize node traffic
trafficLoad = zeros(numNodes,1); % Traffic load on each node
attackDuration = 100; % Duration of the attack in seconds
simulationTime = 200; % Total simulation time
% Normal Traffic Simulation
for t = 1:simulationTime
for i = 1:numNodes
if i ~= targetNode && i ~= attackNode
trafficLoad(i) = trafficLoad(i) + normalPacketRate;
end
end
% DoS Attack Simulation
if t <= attackDuration
trafficLoad(targetNode) = trafficLoad(targetNode) + attackPacketRate;
else
% Restore normal traffic after the attack duration
trafficLoad(targetNode) = trafficLoad(targetNode) + normalPacketRate;
end
end
% Calculate Attack Impact
avgTrafficLoad = mean(trafficLoad);
targetTrafficLoad = trafficLoad(targetNode);
% Display Results
disp([‘Average Traffic Load on Network: ‘, num2str(avgTrafficLoad)]);
disp([‘Traffic Load on Target Node Due to Attack: ‘, num2str(targetTrafficLoad)]);
Explanation of Code
- Network Setup: The node beginning with usual packet distribution rates to replicating the common network traffic.
- Attack Simulation: The attacker node since upsurge the packet rate to their direct node for a particular time to replicating the DoS threats.
- Result Calculation: Estimate the effort of the DoS attack by evaluating the load on the target node related to the network’s average load.
Extending the Code for Other Intrusion Attacks
We need to extent the replication to involves different intrusion attacks:
- Man-in-the-Middle Attack: To evaluating the information to seizure the packets among their nodes through routing traffic via attack to the nodes.
- Packet Sniffing: To calculate the data packets from the specific nodes to track the complex data.
- Brute Force Attack: To replicate the continued login efforts by means of transmitting the multiple authentication requests to detecting the response rate.
Visualization of Results
Use MATLAB’s plotting functions to visualize the impact:
- Line Plot The traffic over the load time.
- Histogram To show the packet loss or latency distribution.
- Heatmap To display the ostentatious nodes.
% Plot traffic load over time for the target node
timeVector = 1:simulationTime;
targetTrafficVector = ones(1,simulationTime) * normalPacketRate;
targetTrafficVector(1:attackDuration) = attackPacketRate; % Simulate DoS attack impact

plot(timeVector, targetTrafficVector, ‘-r’, ‘LineWidth’, 1.5);

ylabel(‘Packet Rate’);
