E-commerce web applications handle sensitive customer information, credit card tokens, and payment processing configurations. They represent primary targets for malicious injection scripts and data theft.
Securing Payment Gateway Bridges
Standard security compliance requires that payment details must never touch your database in plaintext. Implementing secure tokens via checkout integrations (like Stripe or PayPal) guarantees that physical card details remain isolated. All checkout state updates must be validated on the server side to prevent users from modifying item prices in browser memory before transaction submission.
Mitigating Cross-Site Scripting (XSS)
XSS attacks occur when custom user fields allow rendering raw HTML/JS. Implementing strict context-aware output escaping prevents injection scripts from executing in customer sessions. Regular audits, setting strict Content Security Policies (CSP), and utilizing automated dependency checks keeps your shop environment safe and trusted.
