A new framework enhances Intrusion Detection Systems (IDS) evaluation by harmonizing data and benchmarking models. Feature harmonization significantly boosts performance, with Random Forest achieving 98.0% accuracy.

Area of Science:

Cybersecurity
Machine Learning
Network Security

Background:

Intrusion Detection Systems (IDS) are vital for network security.
Current machine learning-based IDS evaluations suffer from dataset dependency, lack of reproducibility, and transparency issues.

Purpose of the Study:

To propose a unified, transparent, and statistically grounded framework for evaluating IDS.
To address challenges in IDS performance assessment, including feature harmonization and multi-model benchmarking.

Main Methods:

Developed a preprocessing pipeline to harmonize features from NSL-KDD and CICIDS2017 datasets.
Benchmarked diverse machine learning models (supervised, unsupervised, deep learning, ensemble) using cross-validation.
Employed statistical validation tests (Wilcoxon signed-rank, McNemar's, DeLong).

Introduced a cryptographic logging mechanism (SHA-256 hash chaining) for result traceability.

Main Results:

The Random Forest model demonstrated superior performance with 98.0% accuracy and 97.0% F1-score on harmonized data.
Ablation analysis confirmed feature harmonization as the most critical factor for performance improvement.
The cryptographic logging mechanism provided tamper-evident traceability but was less effective than blockchain.

Conclusions:

The proposed framework offers a reproducible and statistically robust method for evaluating IDS.
Feature harmonization is crucial for enhancing IDS performance and generalization.
The study emphasizes the need for transparency and standardization in cybersecurity research.
