"Meningkatnya jumlah pengguna internet saat ini memberikan banyak dampak pada kehidupan manusia, karena internet menghubungkan banyak perangkat setiap hari. Perkembangan ini membawa berbagai dampak positif maupun dampak negatif. Salah satu dampak negatifnya adalah adanya aktivitas berbahaya yang dapat menyerang jaringan. Intrusion detection system merupakan sebuah sistem manajemen keamanan pada jaringan komputer. Data yang dimiliki intrusion detection system mempunyai fitur yang cukup banyak tetapi tidak semua fitur yang ada relevan dengan data yang digunakan dan jika data tersebut diolah akan memakan waktu yang cukup lama. Oleh karena itu, diperlukan pemilihan fitur untuk meningkatkan akurasi serta memperpendek waktu pembelajaran. Beberapa metode pembelajaran sudah pernah diterapkan untuk menyelesaikan masalah intrusion detection system, seperti Na ? ve Bayes, Decision Tree, Support Vector Machines dan Neuro-Fuzzy Methods. Metode pemilihan fitur yang digunakan untuk skripsi ini adalah metode Chi-Square. Setelah dilakukan pemilihan fitur, akan didapatkan hasil berupa sebuah dataset baru yang kemudian akan diklasifikasi menggunakan metode Extreme Learning Machines. Hasilnya menunjukkan setelah dilakukan pemilihan fitur dengan metode Chi-Square, tingkat akurasi akan meningkat serta waktu yang dibutuhkan algoritma pembelajaran untuk menyelesaikan metode tersebut menjadi semakin singkat.

The increasing rates of internet users nowadays must be give much impacts to our lifes, because the internet things can connect more devices every day. This growth carriers several benefits as well as can attack the network. Intrusion detection system IDS are used as security management system. IDS can be used to detect suspicious activity or alert the system. IDS involves large number of data sets with several different features but not all features are relevant with the data sets and it takes long computational time to solve IDS data sets. Therefore, it has to do feature selection to remove the irrelevant features, to increase the accuracy and to shorten the computational time for the learning methods.

Many researches about learning method to solve intrusion detection system problem have been done to develop and test the best model from various classifiers, such as Na ve Bayes, Decision Tree, Support Vector Machines, and Neuro Fuzzy Methods. For this thesis, the feature selection methods will be used is Chi Square methods to reduce dimentionality of IDS data sets. The new IDS data sets with the best selected features are obtained afterwards, and then these new data sets will be classified with Extreme Learning Machines methods. The result denotes that Extreme Learning Machines classification methods provides better accuracy level while combined with Chi Square feature selection."

"Salah satu tantangan utama investigasi insiden kebocoran data adalah tidak tersedianya kerangka kerja spesifik yang sesuai dengan karakteristik insiden kebocoran, disertai langkah-langkah yang jelas dan memberikan hasil investigasi yang komprehensif. Tantangan lain berupa proses analisis terhadap logs berjumlah besar akan menghabiskan waktu dan berpotensi terjadi human-error bila dilakukan secara manual. Pendekatan machine learning (ML) dapat dijadikan solusi, namun kinerja ML seringkali tidak optimal dikarenakan kondisi ketidakseimbangan dataset. Untuk itu, pada penelitian ini dikembangkan kerangka kerja forensik digital baru yang bernama KARAFFE (Kalamullah Ramli–Arif Rahman Hakim–Forensic Framework for Exfiltration), yang bersifat spesifik sesuai dengan karakteristik kebocoran data. Tahapan dan komponen pada KARAFFE mampu menghasilkan jawaban atas pertanyaan investigatif berupa What, When, Who, Where, Why dan How (5WH) dari insiden yang diinvestigasi. Berdasarkan karakteristik pembanding yang ditetapkan, KARAFFE memenuhi enam indikator karakteristik mengungguli kerangka kerja existing lainnya. Lebih lanjut, analisis studi kasus menunjukkan bahwa KARAFFE mampu menginvestigasi insiden secara utuh disertai jawaban 5WH yang lengkap atas insiden yang diuji. Metode lain yang dikembangkan adalah ARKAIV (Arif Rahman Hakim-Kalamullah Ramli-Advanced Investigation). Metode ARKAIV berbasis ML mampu memprediksi terjadinya exfilration berdasarkan event logs yang dipetakan ke adversarial tactics. Untuk prediksi tersebut dilakukan modifikasi dataset berupa rangkain tactics dengan exfiltration sebagai target dan didesain skema resampling untuk mengatasi kondisi ketidakseimbangan dataset. SMOTEENN menghasilkan kinerja terbaik mengungguli empat teknik resampling lainnya, dengan meningkatkan nilai geometric-mean 0 pada initial dataset menjadi 0.99 pada resampled dataset. Selain itu, model ML pada metode ARKAIV dipilih dengan kinerja paling optimal berdasarkan lima teknik feature selection, menerapkan lima classifiers ML, dan dua teknik validasi model. Hasil ML-ARKAIV menunjukkan bahwa Random Forest melampaui kinerja empat classifiers lainnya (XGBoost, Logistic Regression, Naive Bayes, dan Support Vector Machine), dengan mean accuracy sebesar 99.1% (5-folds), 99.8% (10-folds), 99.7% (5-folds 5-repetitions), dan 99.74% (10-folds 10-repetitions). Selain itu, analisis studi kasus menunjukkan bahwa ARKAIV mampu memprediksi secara akurat dua insiden exfiltration dan satu insiden non-exfiltration. Dengan demikian, ARKAIV menunjukkan konsistensi kinerja dan efektifitasnya dalam memprediksi terjadinya exfiltration dalam berbagai skenario.

One of the primary challenges in investigating data breach incidents is the lack of a specific framework tailored to the characteristics of such incidents, accompanied by clear steps to ensure comprehensive investigative results. Another challenge lies in the analysis of large volumes of logs, which is time-consuming and prone to human error when performed manually. Machine learning (ML) approaches offer a potential solution; however, their performance is often suboptimal due to the imbalance in datasets. This study proposes a novel digital forensic framework named KARAFFE, designed specifically to address the unique characteristics of data breach incidents. The stages and components of KARAFFE are structured to answer investigative questions encompassing What, When, Who, Where, Why, and How (5WH) of the incidents under investigation. Case study analysis demonstrates that KARAFFE provides a complete investigation of incidents, delivering comprehensive 5WH responses for the examined cases. Based on the established comparative characteristics, KARAFFE meets six key indicators, outperforming other existing frameworks. Furthermore, the case study analysis demonstrates that KARAFFE enables comprehensive incident investigation, providing complete 5WH answers for the tested incidents. Additionally, this study introduces the ARKAIV method. ARKAIV is an ML-based approach capable of predicting exfiltration attacks based on event logs mapped to adversarial tactics. To facilitate these predictions, the dataset was modified to include a sequence of tactics with exfiltration as the target, and a resampling scheme was designed to address dataset imbalance. SMOTEENN achieved the best performance, surpassing four other resampling techniques by improving the geometric mean value from 0 on the initial dataset to 0.99 on the resampled dataset. Furthermore, the ML models in ARKAIV were selected for optimal performance through the application of five feature selection techniques, five ML classifiers, and two model validation methods. The results of ML-ARKAIV indicate that Random Forest outperformed four other classifiers (XGBoost, Logistic Regression, Naive Bayes, and Support Vector Machine), with mean accuracy rates of 99.1% (5-folds), 99.8% (10-folds), 99.7% (5-folds with 5 repetitions), and 99.74% (10-folds with 10 repetitions). Additionally, the case study analysis demonstrated that ARKAIV accurately predicted two exfiltration incidents and one non-exfiltration incident. These findings underscore ARKAIV's consistent performance and effectiveness in predicting exfiltration across various scenarios."
