Language-specific defenses

Defending against standard web attacks requires implementing security measures specific to the programming language used in a web application. Here are some language-specific defenses against common web attacks:

• PHP:
  • Filter input data: Use functions such as filter_input() or mysqli_real_escape_string() to sanitize user input and prevent SQL injection
  • Prepared statements: Employ prepared statements and parameterized queries to protect against SQL injection attacks
  • Cross-Site Scripting (XSS) prevention: Use htmlspecialchars() or htmlentities() to escape user input when displaying it in HTML to prevent XSS attacks
  • Session security: Store session data securely, use secure session handling functions, and regenerate session IDs after successful logins.
  • Content Security Policy (CSP): Implement CSP headers to control which resources can be loaded and mitigate XSS attacks.
• Java:
  • Input validation: Validate and sanitize user input to prevent common vulnerabilities...
