Blockchain for Secure Data Transmission
The TTOCDM-XAIRNN methodology integrates Blockchain (BC) technology to ensure secure inter-cluster data transmission. BC functions as a distributed, immutable ledger storing segmented transaction data, including hash values, timestamps, and links to previous blocks. This structure makes it highly challenging for attackers to compromise information, as each block's cryptographic value is verified by miners. Decentralized storage solutions like SiacoinDB, Swarm, and IPFS are utilized, significantly enhancing data protection and integrity by associating data with the most recent block via smart contract code.
Enhanced Data Quality with Linear Scaling Normalization (LSN)
Initial data preprocessing in TTOCDM-XAIRNN utilizes a Linear Scaling Normalization (LSN) model. LSN standardizes input features within a range of [0, 1], which is crucial for improving model performance, training stability, and accelerating convergence. It effectively handles noisy, high-dimensional data common in cyber threat datasets by capturing local patterns and preserving structural relationships. This technique prevents overfitting, mitigates data loss, and ensures that all features contribute equitably to the model's learning, leading to more precise detection of subtle cyberattack patterns.
Pelican Optimization Algorithm (POA) for Feature Selection
For dimensionality reduction, the methodology employs the Pelican Optimization Algorithm (POA) to identify the most relevant data attributes. POA, a bio-inspired metaheuristic, excels at exploring vast search spaces, balancing exploration and exploitation to mitigate local optima. This results in a more optimal subset of features, significantly improving model accuracy and reducing computational overhead. Its adaptability to dynamic datasets and faster convergence make it highly effective for real-time IoT environments, surpassing conventional filter or wrapper techniques in speed and precision.
Hybrid A-LSTM-BiGRU for Advanced Threat Detection
Cyber threat detection is performed using a hybrid attention-based Long Short-Term Memory and Bidirectional Gated Recurrent Unit (A-LSTM-BiGRU) technique. This powerful model effectively captures both temporal and contextual dependencies in sequential data, which is vital for detecting advanced cyber threats. The integration of attention-based LSTM with bidirectional GRU enhances memory retention and bidirectional sequence learning, allowing the model to detect complex patterns that simpler models might miss. The attention mechanism further improves focus on critical input features, leading to better interpretability and precision, and achieves superior accuracy and robustness against evolving attack behaviors.
Earthworm Optimization Algorithm (EOA) for Hyperparameter Tuning
To ensure optimal detection and mitigation capabilities, the Earthworm Optimization Algorithm (EOA) is implemented for hyperparameter tuning. EOA is chosen for its exceptional efficiency in balancing exploration and exploitation within high-dimensional search spaces, which is critical for optimizing Deep Learning methods. By mimicking the natural foraging and movement behavior of earthworms, EOA adaptively updates solutions, efficiently escaping local optima. This leads to faster convergence and better precision in tuning critical parameters, enhancing overall model performance, generalization, and making it suitable for dynamic IoT settings.
Transparent Decision-Making with Explainable AI (SHAP)
The methodology incorporates Explainable AI (XAI) with SHAP (SHapley Additive exPlanations) to provide transparent insights into model decisions. SHAP allocates significant scores to each feature, indicating its contribution to the final prediction. This is crucial for building trust in AI systems, especially in sensitive domains like cybersecurity. By offering a clear understanding of why a particular threat was identified and how the model arrived at its conclusion, SHAP supports informed decision-making and enhances the overall threat mitigation process, making AI less of a "black box" and more of a trusted partner.
