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.

Are you professor in Stanford? amazing level of mentoring and knowledge of the subject

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.

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

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

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

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.

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

Thanks man 👍 for this series. Please continue.

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.

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

thanks love the vidios!

Thanks

Please create complete course on springsecurity thanka

That's great

ohh great video

hahaha, the principal joke was hilarious ! .... also thanks for the video!

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

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?

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

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

Joined :)

Hi Sir, could you please upload on Docker or Kubernettes

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

👍

Does Spring Security support JWT and token verification?

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

Happy Teacher's day :)

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

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

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

First view first comment

"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.

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

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

It looks for me Authroization and Granted Authority are same.

Sir I have Join course

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 .

Hated principal in primary school 😀😀😀😀

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
