Authentication, authorization, input validation, secure coding practices, and API rate limiting

In this section, we will discuss some of the core principles of secure software development and API management.

Authentication

Authentication is the process of verifying the identity of a user, device, or system. It often involves a username and password but can include any other method of demonstrating identity, such as biometrics.

Best practices for authentication are as follows:

• Use strong authentication mechanisms such as Open Authorization 2.0 (OAuth 2.0) or JSON Web Token (JWT).
• Implement multi-factor authentication (MFA) for added security.
• Centralize authentication to a dedicated service when possible.

The following are some key considerations for authentication:

• Ensure secure transmission of credentials.
• Regularly audit and monitor authentication logs.
