Chris Greer - Hands-On TCP/IP Deep Dive with Wireshark - How this stuff really works

[number6]

Abstract:

Thursday from 0900 to 1300
EventBrite Link: https://www.eventbrite.com/e/chris-g...s-378876127697

Let's break out Wireshark and dig deep in to the TCP and IP protocols. This skill is critical for anyone interested in any area of cybersecurity, no matter the color of the hat. Almost all enumeration, scans, incident response, and traffic forensics require the analyst to dig into and interpret TCP conversations. When enumerating an environment, identifying key TCP/IP indicators in protocol headers can also help when passively fingerprinting systems.

In this workshop we will roll back our sleeves and learn how TCP/IP really works - the handshake, options, sequence/ack numbers, retransmissions, TTL, and much more. This workshop welcomes all cybersecurity and wireshark experience levels.

Skill Level: Beginner to Intermediate

Materials Needed: Just a laptop with a copy of Wireshark. I will provide the sample pcaps for analysis.

Bio:

Chris Greer is a network analyst and Wireshark instructor for Packet Pioneer, a Wireshark University partner. He has focused much of his career at the transport layer, specifically TCP, specializing in how this core protocol works to deliver applications, services, and attacks between systems. Chris is a regular speaker at Sharkfest - the Wireshark Developer and User Conference. He has presented at DEFCON and other industry conferences and regularly posts Wireshark analysis tips to his YouTube channel.

Hi there, what is the date and time of the scheduled work? and how do I register for it? Thanks!

I do not speak for Workshops, or have any authority over details, but I can provide hints based on the past.
What I have posted about workshops are details I was provided to post by the person organizing workshops ( https://twitter.com/magen_wu .)

Workshops generally tend to happen leading up to DEF CON weekend.
Last year ( DEF CON 29, in the year 2021) a page ( https://defcon.org/html/defcon-29/dc-29-workshops.html ) shows workshops were on Friday and Saturday.
As we get closer to the Workshops being made available for sign-up (announced to happen Noon, PDT, July 5, 2022) some page should be announced with the sign-ups showing the schedule for each.
DT added an event to the forum calendar for when sign-ups will take place: https://forum.defcon.org/node/241921
Once sign-ups are posted, details should mention when each workshop is expected to take place.
Announcement on twitter: https://twitter.com/magen_wu/status/1534517795383287809 and you can see the official DEF CON account on twitter re-tweeted if you check details on that tweet.
