Introduction to the Network Disruption Detection System

In today's digital era, computer network security is a top priority. As technology advances, the threat of cyber attacks and network disruptions continues to grow. One of the most effective methods to increase security is to use an intrusion detection system (IDS). This article will discuss the analysis and design of computer network disorder detection system applications that utilize Artificial Neural Networks (ANN) with Multilayer Feedforward architecture and backpropagation training algorithms.

The IDS system is a tool used to monitor network and computer systems activities, as well as detect potential threats or violations. In this approach, we use an artificial neural network model that is inspired by the workings of the human brain. Multilayer feedforward architecture consists of several layers: input layers, one or more hidden layers, and output layers. Each of these layers can contain one or more neurons, which is in charge of processing input signals and produces the appropriate output.

The Importance of Normalization and Training

The input signal received by the Intrusion Detection System comes from normalized intrusion data so that its value is within the range of 0 to 1. The normalization process is very important to ensure that the ANN model can process data effectively. After the data is normalized, the model will be trained using a backpropagation algorithm. This process involves adjusting parameters and weight based on the results of the training. When a minimum error level is achieved, the predetermined parameters and weight can be used to detect intrusion better.

The backpropagation algorithm is a widely used training method for ANN models. It works by propagating the error backwards through the network, adjusting the weights and biases of each layer to minimize the error. This process is repeated until the desired level of accuracy is achieved.

The Results of Training and Performance Analysis

Based on the results of the training, if the error rate is targeted at 1x10^-7, then the minimum error rate that can be achieved is 9.28x10^-7 with one hidden layer consisting of 15 neurons. These results are obtained in one second with 12 Epoch iterations. This shows the efficiency of architecture with one hidden layer. Conversely, testing with more than 15 neurons in one hidden layer does not show significant improvement of performance. In experiments with 50 neurons, the error rate recorded only 0.164 with the time required to reach 39 seconds and 32 EPOCH.

These results indicate that increasing the number of neurons is not always directly proportional to increased accuracy in intrusion detection. In fact, adding more neurons can lead to overfitting, where the model becomes too complex and starts to fit the noise in the training data rather than the underlying patterns.

The Benefits of Multilayer Feedforward Architecture

The multilayer feedforward architecture is a powerful tool for intrusion detection. By using multiple layers of neurons, the model can learn complex patterns and relationships in the data. The hidden layers can be used to extract features from the input data, which can then be used to make predictions.

In this study, we used a single hidden layer with 15 neurons, which proved to be efficient in detecting intrusions. However, the results also show that increasing the number of neurons does not always lead to improved performance. This suggests that the optimal number of neurons will depend on the specific problem and dataset being used.

Conclusion and Future Work

The computer network disorder detection system using multilayer feedforward architecture and backpropagation training show promising results. Ann training with one hidden layer and 15 neurons proved efficient, with relatively short training time and low error rates. This study suggests that researchers and network security practitioners consider the optimal ANN structure to increase the effectiveness of the intrusion detection system.

With technology that continues to develop, the application of this system can be further enhanced to protect networks from increasingly complex threats. Future work could involve exploring other architectures and training methods, such as convolutional neural networks (CNNs) and recurrent neural networks (RNNs). Additionally, the use of transfer learning and ensemble methods could also be explored to improve the performance of the system.

Recommendations for Future Research

Based on the results of this study, we recommend the following for future research:

Explore other architectures: Investigate the use of other architectures, such as CNNs and RNNs, to see if they can improve the performance of the system.
Use transfer learning: Explore the use of transfer learning to see if it can improve the performance of the system.
Use ensemble methods: Investigate the use of ensemble methods, such as bagging and boosting, to see if they can improve the performance of the system.
Use real-world data: Use real-world data to train and test the system, rather than simulated data.
Investigate the use of other features: Investigate the use of other features, such as network traffic patterns and user behavior, to see if they can improve the performance of the system.

By exploring these areas, we can further improve the performance of the system and make it more effective at detecting intrusions.

Limitations of the Study

This study has several limitations. Firstly, the dataset used was simulated, which may not accurately reflect real-world scenarios. Secondly, the system was only tested on a small dataset, which may not be representative of the larger population. Finally, the system was only trained on a single type of intrusion, which may not be representative of all types of intrusions.

Future Directions

Future research could involve exploring other architectures and training methods, such as CNNs and RNNs. Additionally, the use of transfer learning and ensemble methods could also be explored to improve the performance of the system. Furthermore, the use of real-world data and other features, such as network traffic patterns and user behavior, could also be investigated to see if they can improve the performance of the system.

Conclusion

In conclusion, this study has shown that the computer network disorder detection system using multilayer feedforward architecture and backpropagation training can be an effective tool for detecting intrusions. The results of this study suggest that researchers and network security practitioners consider the optimal ANN structure to increase the effectiveness of the intrusion detection system. With technology that continues to develop, the application of this system can be further enhanced to protect networks from increasingly complex threats.
