David! It was a ton of fun doing this video with you! Thanks for the opportunity! I love sharing some of the wonders of the SSL and TLS protocols =). Cheers!

[@dhirajverma8600]

CIA triad is about confidentiality integrity and availablity. Not authentication @ some where around in video at 3 to 4 min u mentioned it incorrectly..

[@PracticalNetworking]

@@dhirajverma8600 Some people put "authentication" in "Integrity". Some people list it as it's own service (as I did). This was intentional because achieving all three requires separate processes, which I use to frame the rest of my course picking apart TLS/SSL (that is in fact where these slides are from, is my TLS course).

David this type of content is amazing. I am loving these deep dives you are doing with other SMEs. This content is extremely helpful and I greatly appreciate you working out offer code deals to get content from the SMEs at a discount. Just purchased Ed’s TLS course and Chris’ wireshark course. Super excited to go through both of them! Keep these deep dives coming, the real world examples and the heavy usage of wireshark packet captures to demonstrate what is actually happening is VERY helpful. There are lots of resources online and offline with all the basics, I appreciate you diving into how things really work so we can get a better foundation to design and troubleshoot from. Keep this up, I’m looking forward to more protocols and more deep dives!

[@PracticalNetworking]

Cheers, Kyle. Happy to do more of these =)

[@1Sebastinator]

Error at 3:43: The core CIA principles commonly referenced in cyber security stand for: 'Confidentiality', 'Integrity', and 'Availability'. Note. A is not for 'Authentication' That been said, 'authentication' is often referred to as an extended principle along with 'non-repudiation'.

[@PracticalNetworking]

There are multiple schools of thoughts on this. I chose to use CIA as Authentication because it's possible to do Integrity without truly having Authentication. Besides, the three terms (C. I. Authentication) are each provided differently in Cryptography and by TLS/SSL, and I use those three services to frame the rest of the course as we go deeper and deeper into TLS/SSL. Either way, it's just semantics in the end. =)

Observation. C-I-A, commonly referred to as “A-I-C” instead (so as not to be confused with the US 3 letter agency), stands for Confidentiality-Integrity-“Availability”-not “Authentication”. That is according to CompTIA, but what do I care? I think the IT world has gotten pretty superfluous with their catchy chaining of terms and abundant security-centric phrases to describe stuff.

Would I be correct in understanding that integrity and authenticity are two sides of the same coin: the former protects against tampering by an *unintelligent* adversary (bit flip, lightning strike, script kiddie ignorant of hashing, etc.) while the latter protects against tampering by an *intelligent* adversary?

[@PracticalNetworking]

So... while I agree with you bit flipping is much easier than spoofing authentication, I don't know necessarily if I can consider them two aspects of the same coin. You can attain Integrity without Authentication. I'd recommend this video (the 2nd part in particular), it will help clarify: kzbin.info/www/bejne/l3SnmHl-Zs5leJI

Congrats :) time 53:23 - how does the client perform the hash? time 53:57 - I'd understand using server's public key Question: public key could be used by any bad guy in between. Therefore I have twp notes: 1- the proper keys here are the 'Client session keys' 2- the only verification that matters is the answer from server at time 55:15 where the server summarises all seuqence using its private key Does it make sense to you?
