Digital Defenders CTF 2023 Masterclass Webinar-1

Samgacchadhwam Series Webinar #57

Topic: Network Analysis and Tools
Speaker: Mr. Akshay Dubey, Senior Technical Leader, Cisco Systems India Pvt. Ltd., Bengaluru
Date: Tuesday, 6th June 2023
Time: 3:30 - 5:00 p.m.

Join us for an engaging two-day webinar that covers Network Analysis, Security, and Attacks. This webinar is designed to provide participants with comprehensive knowledge and practical skills in network fundamentals, packet analysis, network attacks, and defense strategies.

On the first day, Akshay Dubey will introduce participants to the basics of networks, including their functioning and different types. Attendees will gain insights into the roles of servers, clients, ports, and protocols in network communication. The session will then shift towards packet analysis, focusing on Wireshark, the most widely used packet analyzer. Participants will explore Wireshark's advantages over other tools, learn how to capture packets, and discover additional tools like TCP Dump for command-line packet analysis. The session will further dive into advanced packet analysis in Wireshark, covering different protocol analysis techniques, packet dissection, filters, and exploring features such as packet hierarchy, conversation filtering, and stream analysis. Additionally, attendees will be introduced to the Scapy module, a powerful packet analysis tool in Python, enabling automation, and simplifying network tasks. Participants will learn about Scapy's functions, including packet filtering, extraction, reading, and network statistics analysis. The session will conclude with an introduction to NMAP, a renowned port scanner, and its usage in network scanning.

Prerequisites:

(a) Basic Networking Knowledge: Familiarity with fundamental networking concepts such as IP addressing, TCP/IP protocols, subnetting, and network topologies will be beneficial.

(b) Operating System Familiarity: Participants should have a basic understanding of operating systems, particularly Windows and Linux. Knowledge of command-line interfaces and basic system administration tasks will be helpful during practical exercises.

(c) Python Basics: Some familiarity with the Python programming language will be advantageous, as certain sessions will involve using the Scapy module for packet analysis. Understanding variables, functions, and basic programming concepts will be sufficient.

(d) Familiarity with Wireshark: While not mandatory, prior exposure to Wireshark or any other packet analyzer will provide a head start in understanding packet capture and analysis concepts.

(e) General Security Concepts: A basic understanding of common security terminologies, such as vulnerabilities, exploits, and malware,
will assist in comprehending the network attacks and defense strategies covered in the webinar.

Please note that these prerequisites are recommended to ensure a smoother learning experience during the webinar. However, even if you are new to some of these topics, the sessions will provide an introduction and build upon the foundational knowledge required.
