Secure coding is crucial for developing robust and reliable software. Here are some key guidelines to follow:

General Best Practices

  • Input Validation: Always validate user input to prevent injection attacks.
  • Use Secure Functions: Utilize secure functions and avoid deprecated ones.
  • Error Handling: Properly handle errors to avoid exposing sensitive information.
  • Session Management: Implement secure session management to prevent session hijacking.
  • Encryption: Use encryption for sensitive data to protect it from unauthorized access.

Language-Specific Guidelines

C/C++

  • Use strncpy() instead of strcpy() to avoid buffer overflows.
  • Always initialize variables to prevent undefined behavior.
  • Use setuid() and setgid() with caution to avoid privilege escalation.

Java

  • Use try-catch blocks to handle exceptions properly.
  • Avoid using System.out.println() for sensitive information.
  • Use PreparedStatement to prevent SQL injection.

Python

  • Use input() with caution to avoid command injection.
  • Always validate user input to prevent injection attacks.
  • Use hashlib for secure hashing.
