The objective of this project is to design and implement a Zero Trust–based Secure Authentication System for enterprise networks. The system follows the principle of “never trust, always verify” by continuously validating user identity, device status, and access permissions to protect organizational resources from unauthorized access.
Study Zero Trust security principles and enterprise network authentication challenges.
Analyze concepts such as continuous authentication, least privilege access, and device verification.
Prepare Software Requirement Specification (SRS) and security architecture documentation.
Design system architecture including authentication server, policy engine, and access gateway.
Create database schema for users, devices, roles, policies, trust scores, and access logs.
Implement secure login with password hashing and multi-factor authentication (OTP simulation).
Develop policy engine to evaluate access requests based on role, device, location (simulated), and trust score.
Implement continuous verification for sensitive resource access.
Apply role-based access control (Admin, Employee, Security Analyst).
Integrate device registration and verification mechanism.
Implement session monitoring and automatic re-authentication for suspicious activity.
Maintain detailed audit logs for authentication and access decisions.
Protect against common threats such as session hijacking and unauthorized lateral movement (simulation).
Perform unit testing, integration testing, and policy validation testing.
Generate dashboard showing trust levels and access attempts.
Prepare complete documentation including ER diagrams, Zero Trust model explanation, flowcharts, and test cases.
Deploy system locally or on cloud for demonstration.
