Hackers use sniffing to intercept network traffic. Learn about how ethical hackers prevent these types of attacks in this course from our Certified Ethical Hacker exam series.
- [Teacher] Hello, my name is Lisa Bock, and I'm a security ambassador. In this course I'll explore my favorite part of ethical hacking, sniffing network traffic. This course is part of the Ethical Hacking series. I'll cover concepts such as the importance of the OSI Model, look at active and passive attacks, and ways to tap into the data stream. I'll review some of the attacks against protocols, such as DNS caching and forgery, a macof attack, and creating a denial of service attack, by depleting the DHCP pool.
And I'll cover how hackers use Ettercap for an effective man in the middle attack by poisoning the ARP cache. I'll show you how headers can tell us the types of servers and browsers that are used during a webpage transaction. In addition, we'll look at Driftnet to capture images. I'll be using Wireshark for most of the course, but I'll review other tools for analysis. Are you ready? Let's get started.
