rkddnwn1359282's honest review, Spring Security Complete Mastery [6.x Revised Edition] course

Personally, I have experience configuring user domains based on JWT, OAuth2, and CSRF tokens, but I took this course because I felt I lacked knowledge about the underlying principles of how they actually work. Although the content is quite extensive, I felt the instructor organized and summarized it so well that I could follow along comfortably. In particular, the structural diagrams were drawn very clearly, so for any parts I didn't understand, I was able to supplement my learning by briefly asking an AI. I highly recommend this to anyone who, like me, has implementation experience but feels lacking in their understanding of Security's structure or theoretical knowledge!
