How-To’s of Network Sniffing

Now it’s time to get hands-on. This lecture covers practical sniffing techniques, showing how to configure sniffing tools and perform basic reconnaissance on live networks. You'll learn how to capture, filter, and analyze traffic, and how attackers extract sensitive data in poorly segmented networks.

Key topics:

• Using Wireshark and tcpdump effectively

• Capturing credentials, HTTP data, and DNS traffic

• Live sniffing lab scenarios

• Ethical considerations and legal boundaries

• How defenders detect sniffing activity
