Kerberos Authentication Explained | A deep dive 

The way you speak is absolutely amazing. Slow, steady, and with pauses in just the right places to allow for complete comprehension. So many videos breeze through information too quickly, requiring back-tracking and frequent pauses. The way it's done here is fantastic!

I'm tempted to give you a kiss for this straightforward, comprehensive, and easily understandable video. Keep up the fantastic work, Rob and Team!

You can tell a smart person by how he makes complex things so easy to understand. 🧚‍♀️💖

I've watched many videos on Kerberos and this is the best one I've found so far. Thorough, easy to follow, and relatively short. By the way, having the whole diagram at 14:32 would be super useful. It'd be great if you could publish it as an image or a PDF.

After 7 tries to understand this, in my current class, and 2 other videos, I came across this video. It was the most straight forward and useful example of this system in function I've found. Thank you for making this!

I've watched half a dozen videos on Kerberos and this was by far the easiest to grasp. Your in-depth explanation of the way the system works was easier to follow than a lot of other "simple" explanations that limit themselves to the high level view. Thank you.

For someone from a non-IT background, this presentation was extremely concise and easy to digest. Keep up the great work :)

I recall researching Kerberos a few years ago. This video is mind-blowingly than anything I found back then. Thank you!

Details of the Kerberos process as taught in my class resource made no sense no matter how many times I read them. Thank you for breaking it down so eloquently (my class resource failed to make clear the TGS was including a second (service) session key). Your presentation was a lifesaver.

Finally, an actual explanation how Kerberos works technically. I've had to read through so many websites "explaining" how it works by simply saying "the user authenticates to the AS" and throwing around terms like TGT, AS, KDC etc. Thanks for this excellent video!

Amazing video! never have I seen someone explaining Kerberos in that smooth and elegant way. Great amazing job!

Thank you Rob !!! This is so far the best explanation. I loved the deeper dive of the message exchange. I paused at every step and took down notes . At the end , when the entire life-cycle of the message exchange was depicted stitched together, I started feeling more connected and confident that I can grasp the concept. Thanks a ton !

It seemed like there was a competition on RU-vid to explain Kerberos as poorly as possible. So glad I found your video (which is clear, detailed, and well diagramed (not some guy reading off rambling sentences while a static image sits there...))

That was the first Kerberos explanation I was able to follow which I believe contained most of the pertinent information. Thanks so much. I particularly appreciated the extra visual detail, with wrappers showing which key encrypted which message. Though I still paused and replayed many parts to let it sink in, it was excellent, and I think I finally have a simple working understanding beyond "a bunch of tickets fly around and then I get in".

What an elegantly presentation and explanation - the organization, delivery, content and order followed to explain all concepts is just super perfect.

Best Explanation, Perfect Voice, Perfect Graphics, And Perfect Speed

The presentation is so fun that I couldn't resist but to hit that Subscribe button in the initial 30 seconds only. No wonder the explanation will be even marvellous, I believe.

The best explanation of Kerberos you can find out there! Great!

Absolutely loved this presentation. The details, the pace, the presentation & graphics. Really well done, thank you!

I haven't yet come across a video on Kerberos better than this. What a brilliant job in explaining a complex technical topic so simply!

I remember studying the entire Kerberos diagram for hours, before one of IS masters exams. This was a great refresher.

The dogs and the explanation of the concept is amazing

By far the best explanation I've seen on YT!

One of the best information videos on Kerberos Authentication I have seen in years. Excellent work!

AMAZING! I've been watching a lot of videos, reading docs and diagrams looking for exactly something like THIS. I am not a native English speaker and even so this is more enlightening than all the spanish videos that I wached. Congrats and thank you very much!

Best explanation on Kerberos, I've ever seen. Great job!

Hope i can repeatedly hit the like button. Most comprehensive explanation ever

Great video in helping me in understanding the complexity of Kerberos. I just sat for the CISSP exam this morning and got a provisionally passed !!! I watched all your videos related CISSP mind mapping as they are really useful material for big picture chunking ... thank you very much Rob

HOLY MOLLY THIS EXPLANATION IS GOLD!!! absolutely awesome!! I was struggling a lot following the process but not anymore!! when the video finished I wanted to applause. Its a superb explanation and the diagrams are sublime :D

What great explanations! Really like the relatively simple breakdown and the full technical data flow

WOW! The video goes into explaining this in extreme detail but its so well explained! Thank you!

Thank you for taking the time to make this video. I always "kind" of understood what kerberos did but this is a very good explanation.

This is the best explained Kerberos I have ever seen. Thank you!

The words never stuck for me, no matter how many times I studied them. Your line diagram of how all the different parts interact just clicked for me and helped me easily visualize 10 steps. Thank you!

This video is simply PERFECT! Really a terrific lesson, thank you!

Thank you very much for the understandable and detailed explanation of kerberos protocol. Noone else in the internet did so. That video is amazing

Holy cow is this complicated… despite this, I don’t think a better job explaining this can be done as it done is here!

Such an articulate presentation, well presented and incredibly easy to follow. You have a talent for teaching, sir. Have been watching several Kerberos videos before yours, and the amount of attention to detail that was presented in a digestible format along with fantastic visual aids really helped me to understand the topic better than any other videos I've seen so far. Kudos to you, keep up the great work!

I passed CISSP exam today! Your contents helped me a lot understanding difficult concept and how they work. Thank you very much from the bottom of my heart.

One of the best explaination and illustration you could find on the internet. I rarely do comment, but your videos and the effort you put to them is moving

You are simply amazing!! Thanks for everything you are doing for the community.

One of the best clips explaining a protocol / flow / technology I have ever seen. Great work guys!

Great presentation. Great animation. One of the best breakdowns of a typically "difficult to get your head" around concept. Well done!

It is like a Kerberos movie😍.... Clearly understood 🤗 Thankyou so much sir🙏🏻

Holy smokes, this is the best video over kerberos I have seen. The quick, concise pacing was awesome. I had to go back and replay sections multiple times to get my thoughts and notes right, but at this point I understand Kerberos more than I ever have. A video explaining when each of these happens in a Windows endpoint would be greatly appreciated. Also, how does it behave when a Windows domain joined client user logs into a workstation with cached credentials, but yet does not have direct LoS to a KDC. What would happen then if the user logs in and regains LoS to a KDC.

The video is so well made. Amazing explanation. I have an exam tomorrow and you just saved me. BIG THANKS

Amazing and easy to understand ... didn';t know how much was involved with Kerberos

Rob, your stuff is really amazing! I've watched other major elearning companies and their videos are boring which makes it extremely difficult to follow. Your style, video editing and explanations are fantastic. Thank you!

Thank you so much for making these videos. I passed my CISSP test yesterday and these videos were a massive help.

This is a fantastic video! Helped me understand something which had previously alluded me! I appreciate your hard work on this!

Hey Rob, this is an elaborated explanation I was looking for thanks again! Hope to see more videos on CISSP concepts/domains.
