Understanding secure coding is critical for building robust and reliable software. This guide provides foundational concepts to safeguard your application.
- Input Validation: Strictly validate all user input to prevent injection attacks. - Output Encoding: Encode data before displaying it to prevent cross-site scripting (XSS). - Least Privilege: Grant only the necessary permissions to your code. - Secure Authentication: Employ strong authentication mechanisms to verify user identities. - Error Handling: Implement graceful error handling to avoid exposing sensitive information. - Data Protection: Protect sensitive data at rest and in transit.
function validateInput(input) {
if (input.length > 10) {
console.error("Input too long.");
return false;
}
return true;
}
This is a simple example demonstrating input validation.
Secure coding practices are paramount for building software that is both functional and safe. Continuously review and update your code.
