Recently, with the massive growth of IoT devices, the attack surfaces have also intensified. Thus, cybersecurity has become a critical component to protect organizational boundaries. In networks, Intrusion Detection Systems (IDSs) are employed to raise critical flags during network management. One aspect is malicious traffic identification, where zero-day attack detection is a critical problem of study. Current approaches are aligned towards deep learning (DL) methods for IDSs, but the success of the DL mechanism depends on the feature learning process, which is an open challenge. Thus, in this paper, the authors propose a technique which combines both CNN, and GRU, where different CNN–GRU combination sequences are presented to optimize the network parameters. In the simulation, the authors used the CICIDS-2017 benchmark dataset and used metrics such as precision, recall, False Positive Rate (FPR), True Positive Rate (TRP), and other aligned metrics. The results suggest a significant improvement, where many network attacks are detected with an accuracy of 98.73%, and an FPR rate of 0.075. We also performed a comparative analysis with other existing techniques, and the obtained results indicate the efficacy of the proposed IDS scheme in real cybersecurity setups.

Detection of intrusions is a system that is competent in detecting cyber-attacks and network anomalies. A variety of strategies have been developed for IDS so far. However, there are factors that they lack in performance, creating scope for further research. The current trend shows that the Deep Learning (DL) technique has been proven better than traditional techniques for IDS. Throughout these studies, we presented a hybrid model that is a Deep Learning method called Bidirectional Recurrent Neural Network using Long Short-Term Memory and Gated Recurrent Unit. Through simulations on the public dataset CICIDS2017, we have shown the model’s effectiveness. It has been noted that the suggested model successfully predicted most of the network attacks with 99.13% classification accuracy. The proposed model outperformed the Naïve Bayes classifier in terms of prediction accuracy and False Positive rate. The suggested model managed to perform well with only 58% attributes of the dataset compared to other existing classifiers. Moreover, this study also demonstrates the performance of LSTM and GRU with RNN independently.

In this research work, various machine learning models such as linear regression (LR), KNN and MLP were created to predict the optimized synthesis of biodiesel from pre-treated and non-treated Linseed oil in base transesterification reaction mode. Three input parameters were included for modelling, reaction time, catalyst concentrated ion, and methanol/oil-molar ratio. In biodiesel transesterification reaction 180 samples run with non-Pre-treated Linseed Methyl Ester (NPLME), Water Pre-treated Linseed Methyl Ester (WPLME) and Enzymatic Pre-treated Linseed Methyl Ester (EPLME) oil as feed stocks and optimized parameters are find out for maximum biodiesel yield to be 8:1 molar ratio, 0.4% weight catalyst, 60 °C reaction temperature.To test the technique, R² and MAPE parameters were used. The average R² values for linear regression, KNN, and MLP are 0.7030, 0.8554 and 0.7864 respectively. Moreover, the average MAPE values for these models are 11.1886, 6.0873 and 8.0669 respectively. Hence, it is observed that the KNN model outperforms other models with higher accuracy and low MAPE score.

The Internet and communications have rapidly expanded, leading to a significant rise in data generation and heterogeneity. Intrusion detection systems play a crucial role in ensuring the security and integrity of computer systems. These systems have been developed by researchers, academicians, and practitioners to effectively detect and mitigate network attacks. Intrusion detection systems are designed to analyze network traffic and compare it with a baseline of normal behavior, allowing them to identify any deviations or inconsistencies that may indicate an intrusion. Furthermore, the cooperative and distributed architecture of intrusion detection systems enables them to effectively detect attacks and protect the network from unauthorized access. Additionally, to enhance the performance of intrusion detection systems, techniques such as resampling the dataset and utilizing classifier ensemble are used to improve the classification accuracy. Moreover, intrusion detection systems have been integrated with intrusion response systems to ensure a timely and effective response to detected attacks. AI-based Intrusion Detection Systems have emerged as a crucial tool in ensuring network security and combating cyber threats. These systems utilize artificial intelligence algorithms to analyze network traffic, identify patterns of malicious activity, and detect potential cyber-attacks. They have proven to be highly effective in improving the detection accuracy, reducing false alarms, and even detecting previously unknown types of attacks. In summary, the development of accurate and efficient intrusion detection systems is crucial for ensuring network security. In today’s rapidly changing world, the significance of accurate intrusion detection systems cannot be overstated.
