Ethical Hacking

Sniffers

This course is a part of Become an Ethical Hacker, a 20-course Learning Path series from LinkedIn Learning.

Ethical hackers: Get an inside look into the tools the black hat hackers use to "sniff" network traffic, and discover how to countermeasure such attacks. Security ambassador Lisa Bock explains what a sniffer is, and how hackers use it to intercept network traffic. She reviews the seven-layer OSI model, active vs. passive attacks, and the different types of protocol attacks, including MAC and macof attacks, DNS caching and forgery, DHCP denial-of-service attacks, and ARP cache poisoning. Learn how ethical hackers have an arsenal of tools to emulate these attacks and techniques, from examining headers and URLs to capturing images. Lisa relies on Wireshark, a network protocol analyzer for Unix and Windows, but also introduces other sniffing tools, including TShark, tcpdump, and CloudShark.
