Gain insights into JWT, OAuth2, and OpenID Connect. Learn about HTTPS, encryption, and handshake techniques, and explore foundational concepts in web API security for enhanced application protection.

Web application developers are always on the lookout for ways to secure their applications. It has become the most fundamental part of any web application considering the rise in the number of cyber-attacks. This course will be your handy guide to the basic terminologies and frameworks related to web application security.

 In this course, you will learn what JWT is, how a JWT is created, and what benefits it provides in token-based authentication. You will learn about why HTTPS was introduced and how it revolutionized the way data is transferred using techniques like encryption and handshake. You will also dive deep into the most commonly used authentication and authorization frameworks called OAuth and OpenId Connect. This course will give you a taste of what web API security is all about and will give you the foundation so you can further your learning of application security.

Web Security and Access Management: JWT, OAuth2 & OpenId Connect

This grant type is used for machine to machine authorization. There is no user involved in this flow.
Suppose we have an application that follows the microservices architecture. The application is divided into small parts and each part is deployed on a separate server.

If one internal server needs to access some data from the other server, then they can use the client credentials grant type.

This lesson discusses the Client Credentials grant type.
