Payment Systems Security
Payment Systems Security is a specialized field of cybersecurity that applies computer science principles to protect the digital infrastructure, protocols, and sensitive data involved in financial transactions. It encompasses the entire payment ecosystem, from point-of-sale terminals and online shopping carts to the complex networks that authorize and settle funds. The core objective is to ensure the confidentiality, integrity, and availability of payment information by implementing robust measures such as end-to-end encryption, tokenization, secure coding practices, and multi-factor authentication to prevent fraud, data breaches, and unauthorized access.
