This course investigates the scanning tools and techniques used to obtain information from a target system, including ping sweeps, UDP scans, and TCP flags. Instructor Lisa Bock discusses scanning techniques and their objectives, then goes over vulnerability scanning and how to predict possible attack paths. Lisa introduces scanning tools for port scans, fingerprinting OS, time syncs, and more, then shows you some ways that hackers counter detection via evasion, concealment, and spoofing. She also addresses how to reduce the threat of tunneling, a method hackers use to circumvent network security.
Note: The Ethical Hacking series maps to the 20 parts of the EC-Council Certified Ethical Hacker (CEH) exam (312_50) version 10.

Skill Level Intermediate
- [Lisa] After conducting a thorough footprinting and reconnaissance exercise, the ethical hacker is then armed with more information on the target and has a better idea of how malicious parties might get deeper into a system. But just what are we scanning and why? Hi, my name is Lisa Bock and I'm a security ambassador. In this course, I'll explore the second phase of ethical hacking, scanning. I'll review scanning techniques and the variety of tools used to obtain information from our target system, including specially crafted packets, TCP flags, UDP scans, and ping sweeps.
I'll discuss mapping the network and vulnerability scanning and investigate some tools such as Nmap, Nitco, and other tools. Finally, I'll discuss ways to evade detection using onion routing and tunneling techniques, along with ways to identify and counter port scanning. I'll explore many of the tools and techniques of scanning and also the logic behind the scans. This course is part of the Ethical Hacking series.
