Language-specific defenses

Different programming languages may have specific features and functions to handle input validation and sanitization. Some older and lower-level languages, such as C and C++, require more manual programming to defend against input attacks. Here are language-specific defenses for input validation and sanitization in some commonly used programming languages:

• Java:
  • Input validation:
    • Use libraries such as Apache Commons Validator for validating various types of input (for example, emails, URLs, and so on)
    • Leverage regular expressions for complex input validations
  • Input sanitization:
    • Use the Enterprise Security API (ESAPI) library for input validation and encoding to prevent common security vulnerabilities
    • HTML-encode user inputs when rendering dynamic content in web applications
• Python:
  • Input validation:
    • Utilize built-in libraries such as re for regular expression-based validation
    • Leverage the validator library for validating various types of data...
