I was working on a project and had a lot of trouble with security and authentication/authorization. I learned the general flow by cloning the free lecture (Spring Security 5.x) from another place and then modified the source codes in the blog to fit my project, but I felt that it was not enough. Most of the existing books and lectures were based on Spring Security 5.x version, so there were many differences from 6.x. In particular, in the security setting part, 5.x uses a simple method, but from 6.x, lambda expressions are required, so I had to googling every single thing while wondering if it was right. I applied JWT and OAuth2 to the project with Googling and Spring Security in Action 2nd Edition and GPT4, and the server worked, but I was very uneasy about applying authentication/authorization without properly understanding it, so I decided to take the lecture. I was worried that there would be a lot of overlap with Spring Security in Action 2nd Edition, but the detailed parts that were not covered in the book were covered in detail, so I was able to clearly understand the concepts that were ambiguous. For those who are learning for the first time, I recommend 5.x version + ChatGPT4 or 4o (since most of the learning data is 5.x version, it presents a lot of deprecated code) + don't waste time Googling and just listen to this lecture😭 + If you are completely new to Spring Security, I recommend Spring Security in Action 2nd (6.x version or higher) sold by Manning + official documentation. I do not recommend studying 5.x version.

Finally, I'm done!!! First of all, I liked the previous version of the lecture. I like this Security 6 version more than the previous 5 version! The more I take the lecture, the more I realize that the instructor has done a lot of analysis on the new version and created the lecture. I'll write down some features that might be helpful to others. 1. Place the filter initialization part in front of the leaf I am also really satisfied with the fact that the initialization process is placed at the very front 2. Separation of theory and practice parts The lecture is divided into each part, so it is easy to watch in about 20~30 minutes 3. Branch management for each part The branches are divided into each part, so it is very useful for taking the class 4. Teaching ability There is no need to say anything about the teaching ability, and among the security lectures or textbooks I have seen, This is a lecture that is really like light and salt Just adding a library and turning on the server, a lot of things happen... It is good because it is not a lecture that simply uses functions and ends In addition, you can develop insight into various Spring technologies What I hope for... Can you also give a new lecture on OAuth2!!!

The lecture time is 36 hours and 55 minutes, so it is scary when you first watch the lecture. I also felt resistance when I first learned this part... However, the true value of this lecture is the part where the internal operation principles are explained in detail through the debugger. As you follow the lecture to dig into the detailed operation principles through the debugger, you will learn how to use the debugger yourself, which was a great help in improving your development skills. If you follow this lecture at the stage where you have gone through the Spring introductory stage (learning core, web, jpa, boot, etc.) and learn the internal automatic settings and operation flow through the debugger, you will feel that your understanding of security will grow rapidly. And as of now, most of the security-related materials are based on deprecated or unused materials, but this lecture was created with version 6 and later in mind. It is hard to find lectures or materials that explain security, or even specific technologies, in such depth. This is a lecture that I really recommend.

What you will gain after the course

  • Complete mastery of Spring Security's basic API and related filters

  • Understanding the internal architecture of Spring Security and the roles and relationships between objects

  • Understanding Spring Security's authentication principles and internal workings

  • Understanding Spring Security's authorization principles and internal workings

  • Understanding how to integrate Spring Security and Spring MVC

  • Learn how to build a practical security system using Spring Security.

Spring Security 6.x latest version completely revised!!

Spring Security 6.x offers significant changes and improvements over previous versions, and this tutorial focuses on those changes and new features .

Accordingly, many of the curriculum items have been changed or newly added compared to the existing Spring Security course. In particular , the authorization area of Spring Security has undergone significant changes compared to the previous version, to the point where the entire framework has been rewritten .
Therefore, this Spring Security Complete Mastery course analyzes and delves into the major changes and new features of Spring Security 6.x version in detail. If the students thoroughly learn each function and API through the theory and practice of this course, it will be of great help to those who have development experience in previous versions as well as those who are new to Spring Security in developing applications using Spring Security in a practical environment.


Courses for beginners, intermediate, and advanced learners

This course is designed for beginners who are new to Spring Security, as well as intermediate and advanced users who have basic knowledge or experience but want to acquire more in-depth knowledge and deeply understand the core principles, internal structure, and operating methods of Spring Security and apply them.

Key Learning Contents 💡

This course focuses on the core topics of Spring Security, focusing on five main axes: authentication, authorization, exploit protection, integration, and practical projects .

1. Authentication

Spring Security 6.x provides various methods for user authentication, including form-based authentication, basic authentication, and remember-me authentication. These authentication methods provide an effective means for users to prove their identity to the system. The authentication process verifies the user's identity by verifying the credentials provided by the user, and this process is centered around AuthenticationManager . After successful authentication, the user's authentication information is stored in SecurityContext within SecurityContextHolder , which is used to reference the user's authentication state throughout the application. Spring Security also manages user session information through session management, providing features such as concurrent session control, session policy configuration, session expiration, and session fixation protection to secure user sessions. It is also designed to handle various exceptions that may occur during the authentication process appropriately.


2. Authorization

Spring Security's authorization process determines whether a user is authorized to access a specific resource after authenticating. Spring Security 6.x allows you to configure URL-based or method-based authorization using HttpSecurity , and a new authorization architecture, including AuthorizationManager , allows you to implement more granular and flexible authorization policies. This allows developers to define access control policies tailored to their application's security requirements and evaluate the permissions of user requests to grant or deny access to resources. Authorization plays a critical role in strengthening application security and is crucial for protecting sensitive information and resources.

3. Protection Against Exploits

Spring Security 6.x provides features such as CORS, CSRF protection, and SameSite cookie settings to protect applications from various security threats. These security features protect applications from cross-site scripting and cross-site request forgery attacks, and keep user data and sessions safe. CORS settings allow developers to securely access resources from other domains, while CSRF protection prevents malicious websites from making requests on behalf of users. Setting the SameSite cookie attribute provides an additional layer of security by controlling how browsers transmit cookies.

4. Integrations

Spring Security 6.x provides tight integration with Servlet environments, Spring MVC, and Spring MVC asynchronous processing. This integration allows developers to easily add and configure security features to Spring-based applications. Servlet integration allows Spring Security to manage the security processing of HTTP requests and responses, while Spring MVC integration enables fine-grained security policies at the controller and service layers. Integration with asynchronous processing addresses the security needs of reactive programming models using Spring WebFlux, enabling developers to effectively manage security when building asynchronous and stream-based applications. This integration allows Spring Security to seamlessly integrate with various Spring application architectures and reduces the complexity of security implementation.

5. Practical Projects

Spring Security 6.x plays a key role in implementing member authentication and member management systems in real-world projects. This allows developers to effectively implement functions such as user authentication, authorization management, and resource access control. The member authentication system provides a foundation for strengthening application security, while the member management system manages the secure storage, retrieval, modification, and deletion of user information. Authorization management assigns different access rights to each user, while resource management controls access to sensitive information and functions within the application. Furthermore, Spring Security supports dynamic authorization configuration using Maps and databases, providing the flexibility to change or update permissions at runtime. These real-world implementations demonstrate the powerful features and flexibility of Spring Security, making it an essential tool for developers to meet security requirements.

        First of all, thank you very much for your valuable evaluation^^ Most of my lectures are produced over a long period of time, so I think you may have a lot of burden before learning like Mr. Ssulji. It is true. However, I personally have a firm standard and principle that I must convey the best knowledge to students in any form regardless of the length of the lecture time, so even if the external appearance of the lecture video is not refined and has advanced marketability, I have a strong will to never compromise or yield on the quality of the internal content, the knowledge transfer, so the video time always ends up being longer than expected!! Of course, I always recognize that it needs to be adjusted appropriately^^ Since it is long, I think you will have a more solid foundation if you follow the difficult parts repeatedly. And I am even more grateful that you felt the charm of debugging^^ If you use it well in practice, it will be of great help, so I hope you continue to develop it as a habit. Thank you again for your sincere evaluation.

      I just listened to what I thought was necessary. The lecture is very long, but I recommend that you watch it three times. At first, I didn't understand what was being said, and I wondered if I should keep listening to it, but the second time, I got a general idea of what it was. I think I'll understand most of it if I listen to it one more time. I've watched it twice, so I'll listen to it one more time. The pronunciation is a bit hard to listen to at double speed, and the feedback from community questions seems a bit slow, so it's a bit disappointing... Aside from that, I think you'll learn most of what you need to know about Spring Security if you study it with this. I recommend it!

        He explains it in great detail, and explains the principles thoroughly. However... his pronunciation is very disappointing. On top of that, he speaks in a dialect, so there are many times when I couldn't understand. It's much harder than other lectures.. Thank you for the great lecture.
