Machine Learning-Based Network Intrusion Detection System

Jun 2024

Built a network IDS using supervised machine learning with SVM and Random Forest classifiers on the NSL-KDD dataset, achieving 92% accuracy and 80% F1-score with 6% false positive rate.

Key Achievements:

  • Achieved 92% accuracy and 80% F1-score with 6% false positive rate after feature engineering and model optimization
  • Used StandardScaler for normalization, SMOTE for class balancing, and 5-fold cross-validation for robust model evaluation
  • Simulated attack traffic including DoS floods, brute-force attempts on SSH/RDP, port scans, and credential misuse

Cryptographic E-Voting Platform with Zero-Knowledge Proofs

Jan 2025

Built a secure e-voting system using PGP encryption (2048-bit RSA), digital signatures (RSA-PSS), and Zero-Knowledge Proof concepts to ensure ballot confidentiality and voter authentication.

Key Achievements:

  • Implemented PGP encryption (2048-bit RSA) for ballot confidentiality and RSA-PSS digital signatures for voter authentication
  • Integrated Zero-Knowledge Proof concepts allowing voters to verify their vote was counted without revealing their choice
  • Built cryptographic commitments to prevent double voting and hash chains for tamper detection

AWS Security Lab - Cloud Attack & Detection

Feb 2025

Built comprehensive AWS security lab environment simulating cloud attacks with corresponding detection rules using GuardDuty, CloudTrail, and Elastic Stack for centralized logging.

Key Achievements:

  • Configured complete AWS security stack: EC2, S3, IAM, CloudTrail, GuardDuty for attack simulation and detection
  • Implemented Elastic Stack for centralized logging and security event correlation
  • Developed attack scenarios: IAM privilege escalation, S3 bucket misconfigurations, EC2 instance compromise, suspicious Lambda invocations
