The objective of this project is to design a secure online payment processing system that ensures confidentiality, integrity, and authenticity of financial transactions. The system protects sensitive user information using encryption, authentication, and secure transaction handling mechanisms.
Study fundamentals of online payment systems and transaction workflows.
Understand common security threats such as data breaches, man-in-the-middle attacks, and payment fraud.
Design system architecture including user interface, payment gateway, and backend services.
Implement secure user authentication using passwords and multi-factor verification.
Apply encryption techniques to protect sensitive payment data during transmission and storage.
Design secure transaction validation and confirmation mechanisms.
Implement session management to prevent session hijacking attacks.
Maintain secure logs for transaction auditing and dispute resolution.
Test the system using simulated payment transactions and attack scenarios.
Evaluate system performance, security strength, and scalability.
Document system architecture, security controls, and limitations
