Packet Tuesday Episode 4: TLS Client Hello. #tls #sec503 #packetlife https://i5c.us/0nGvkP https://isc.sans.edu/diary/29306
Episode 3 of Packet Tuesday is live. This week, it is all about the TCP Urgent flag. Trying to keep them a bit shorter in the future to not spent half an hour on one bit ;-) https://packettuesday.com
I hope everybody is enjoying these as much as I do. Thinking about moving on to some SSL stuff next, but also trying to keep them a bit shorter. Let me know if these work for you, or what I can improve. If I spent half an hour on a TCP flag… who knows how long the SSL Client Hello episode will get :)
And please let me know if I am making mistakes. I am not perfect and actually learn new things as I put these together. Well, I can always claim that I add intentional mistakes to increase “engagement.” :)
