Authentication & Authorization

Who can do what – and how securely?

Authentication & Authorization

Proper management of users and permissions is a critical aspect of every web application. An insecure implementation can lead to unauthorized persons gaining access to sensitive data. At DevCraft Academy, you'll learn how to design authentication and authorization not just functionally, but also securely and maintainably.

Authentication and authorization are the foundation of every secure application. Those who master these concepts can not only control access but also gain user trust and meet regulatory requirements.

Why are authentication and authorization so important?

In a world where data breaches regularly make headlines, secure authentication and authorization are not optional – they're indispensable. Errors in this area can lead to data leaks, legal consequences, and loss of trust. Those who focus on secure implementation from the start protect not only their users but also their business.

What you'll learn with us

At DevCraft Academy, you get comprehensive insight into modern authentication and authorization techniques. You'll learn not just the theory, but most importantly, how to implement these concepts securely and maintainably in real projects.

Our key topics at a glance:

  • Sessions and Cookies: Sessions and cookies form the backbone of many authentication solutions. You'll learn how to securely manage sessions in the database and correctly set cookies to prevent potential attacks.

  • JSON Web Tokens (JWT): JWTs are widely used today, but also vulnerable when incorrectly implemented. We show you how to use JWTs for stateless authentication, what security risks exist, and how to minimize them.

  • Cross-Site Request Forgery (CSRF): CSRF attacks are particularly insidious as they execute legitimate actions on behalf of an authenticated user. You'll learn how to implement effective protective mechanisms against such attacks, such as through anti-CSRF tokens.

  • Authorization: ACLs, RBAC, ABAC: Access control is more than just a login. Whether Access Control Lists (ACLs), Role-Based Access Control (RBAC), or Attribute-Based Access Control (ABAC) – we teach you how to implement differentiated permission systems that are flexible and secure.

  • Secure Handling of Credentials: Usernames and passwords are among the most frequently stolen data. You'll learn how to ensure that credentials never end up in logs or unencrypted in the database and how to handle them securely in the frontend.

  • OAuth: OAuth is the standard for secure and delegated authentication. We explain how OAuth works, what pitfalls exist, and how to securely and correctly integrate it into your application to use external services like Google or GitHub for login.

  • Secure Transmission of Credentials: The transport of user data over the network is a vulnerability. You'll learn how to secure transmission through the use of TLS/SSL and what best practices exist to protect sensitive information.

  • Security Best Practices for Authentication: Two-factor authentication (2FA), regular token refreshing, and password hashing – you'll learn the best practices for secure management of user identities and how to implement them in your application.

  • Practical Tips for Implementation and Maintainability of Authorization Systems: Want a permission system that's not only secure but also easily maintainable? We show you how to design systems so they can be easily adapted to new requirements, and what to pay attention to when building modular authorization logic.

Why DevCraft Academy?

At DevCraft Academy, we focus on hands-on training that not only teaches you the basics but shows you how to implement them in real projects. Authentication and authorization are among the most important security aspects, and you'll learn how to develop secure, flexible, and scalable solutions that also stand up in practice.

Secure authentication and authorization are essential to prevent unauthorized access to sensitive data. At DevCraft Academy, you'll learn how to implement secure sessions, JWTs, and OAuth, how to design ACLs and RBAC, and which best practices help you protect your application from attacks.
