Five Spring Security Concepts - Authentication vs authorization - Java Brains Brain Bytes 

Note taking for my ref: Authentication : who is the user ? Authorization : Are they allowed to do certain things Principal : curently logged in user Granted Authority : way of providing Authorization. Roles : Group of authority.

This is _by far_ the best channel I've encountered on Spring/Java. Incredible. I really appreciate that you give great metaphors (security guard etc) in order to better explain how the frameworks and technologies work.

Simple. Neat. Perfect! Breaking up some of the most technical/confused concepts to layman level in such succinct manner..

I cant find the words to describe your work. Your courses are always well structured and rigorously explained. Been folowing for a long time now. Keep up the good work Kashug

I’ve been waiting for these videos. Excellent content as always Koushik. I’m hoping this series includes Single Sign-On concepts as well :)

How in the world, did you manage to make this easy-to-understand? It is security. You are awesome, man.

Great Presentation, good quality of content, ease understandable by everyone. Awesome Koushik. We all have great respect for you. Thank You.

Thank you koushik ... always waiting for your uploads 👌

Feels like JVM & Spring itself teaching me... Thank you soo much sir from bottom of the heart...

This video is amazing! Explained the most basics of Spring Security with such ease and visual entertainment! By far the easiest and greatest channel to learn Spring!

Thanks man 👍 for this series. Please continue.

Amazing content as usual. Always recommend your channel to my friends and colleagues.

Thanks for helping the students and the developer community by providing these awesome tutorials. I request you to please make more about Spring Security login logout functionalities. Really, you are doing a great job.

You are just Amazing sir!!! You explain things so in depth, with conceptual fundamentals! Love it! I am new in software development space and find it mind boggling, but your videos are that peaceful, satisfying, enriching ride which brings clarity and confidence to keep going ahead. Have become Big Fan of your style!

Koushik is definitely one of the best teachers I've ever encountered on the web!

Thank you so much for making videos on this topic. Applications get compromised on a regular basis, but there seems to be a DMZ between app development and app security! :-) If you can, I would like to see you explain how to handle XSS, SQLi, CSRF etc., within the Spring security framework. Secure webservices would be awesome too. I've also been curious how financial apps and banks mash up data securely, so the user sees information from all their institutions in one place. I wouldn't mind paying for your time either. You're good at what you do and deserve to get paid for it.

You have the best courses on Spring boot! I am really looking forward to your Java courses on your website

Joined :)

I hope to reach to your level of communicating one day.

Hi Kowsik.. one small request.. can you please explain why we need to store passwords in char[] array in java.. why not as string..

Authentication: Bob make's a request to the Server (login purposes) and it is the task of the Security part of the Server, to confirm Bob and find out, that he really is who he claims to be. Principle: After the authentification, Bob's details are saved for following requests. Authorization: Is Bob allowed to do a specific thing? Like deleting a user or even view other user details (not the passwords tho). Granted Authority: Basically this is the part, which actually handles the Authorization in Spring Security. A list of Authority for a specific User (if you wouldn't define Roles) must be setup. Roles: It would be a pain to setup for every single person a List of authorities, that's why Roles basically exist. If Bob has the role "User" and in the "Granted Authority" there is set of defined stuff for this role "User", he is only allowed to do the stuff specified. If he would try to do more than allowed, it would'nt be allowed for him (in the frontend-part he shouldn't even see stuff, he can't modify).

Hello sir, please provide the videos on oauth2 with jwt token using spring security

Happy Teacher's day :)

Hi Sir, could you please upload on Docker or Kubernettes

Can you please add a video in which we can use a custom login page, instead of a default one, how do we call the login API from our own form?

👍

hey I really like your videos please make more we need your help can you make java android development tutorials, Gradle and the diff between Gradle and maven and which one is better, and what the ADF is really all about, and if we should use it or not and the diff between him and spring and also java desktop dev and if we can make a spring boot desktop app please we need your help and tx a lot

Hi Java Brains, Really good presentation! "Principal" is not specific to Spring Security. It's common across all the security frameworks.

Koushik, how can we think of principal, one user having different roles or having different accounts with same role..?

Hi, what could be the approach for context based authorization, like maybe a user should only edit their own comments and not those of other users

Does Spring Security support JWT and token verification?

Hello Sir, i want to restrict multiple user login usinng spring security.Not able to understand.please help

why does app remember principal, when i use jwt token , I would just go and validate the token...do i need to remember principal in this case? Pls do answer

First view first comment

Authentication - Who are you? Authorization- What can you do? Principal - Currently logged in account Granted authority Role

"Principal is someone who I used to hate during my schools :D"

Hi Kaushik, you intro disco song is bit loud. It will be good if you please lower down that.

It looks for me Authroization and Granted Authority are same.

Nice Video but Can you give a real example application that do what you are explained above?

Even in possesion based authentication Hacker can hack the phone and still can grab your secrets

Sir I have Join course

Hated principal in primary school 😀😀😀😀

there are only 2 things authentication , authorization . other things are derivatives , roles are derivative of authorization, Principle of derivation of cookies, grand authorities are derivatives of Roles .

Authorization asked is a using for an avoidance of paying.Avoidance of paying a location to impactfully impose actions desired and or needed agendified without used collecting payment?.a scared or fear emotion that money or currency would change actions and a searching and comparing and or Masterial all over again would have to be imposed?..Depopulate

Thanks
