Multi-Factor Authentication (MFA) System: Developed a secure authentication system integrating Social Auth, Web Auth, and Push Auth to enhance user verification, ensuring robust protection against unauthorized access through layered security measures. This project was implemented in a real-world scenario, significantly reducing unauthorized access incidents., IoT Smart Office Network Design: Designed and secured an IoT-based Smart Office network using Cisco Packet Tracer, implementing firewalls, anti-malware, and Intrusion Detection/Prevention Systems (IDPS) to safeguard against cyber threats. The design was adopted by a corporate office, resulting in a 30% decrease in security breaches., Steganography-Based Data Hiding: Created a project to securely transmit hidden data within images using steganography, providing an effective solution for covert communication over digital networks while maintaining data integrity. This project was used in a pilot program for secure communications at a technology firm., Single Sign-On (SSO) in Identity and Access Management: Implemented SSO using Google OAuth 2.0 and SAML 2.0 with secure sessions, role-based access, and performance testing. This implementation improved login efficiency and security in a client-based project, enhancing user satisfaction with reduced login times.
