🗄️ OLD — Web Application Issues (Accessibility, Testing, Security)

• Accessibility: ensuring usability for people with disabilities (e.g., screen-reader compatibility, WCAG guidelines)
• Testing: cross-browser compatibility, load/performance testing, usability testing
• Performance: page load speed, server response time, scalability under load
• Operation and Maintenance: ongoing hosting, updates, bug fixes, content updates post-launch
• Security: SQL Injection (malicious SQL inserted via unsanitized input), XSS (injecting malicious scripts into pages viewed by other users), CSRF (tricks a user's browser into making unwanted authenticated requests)

MCQ Trap

• SQL Injection targets the database via unsanitized input; XSS injects scripts that run in other users' browsers; CSRF tricks a user's browser into making unwanted authenticated requests — three distinct vulnerability classes.
