Join Lisa Bock for an in-depth discussion in this video Hacking ethically, part of Ethical Hacking: Scanning Networks.
- [Voiceover] The goal of the Ethical Hacking series is to help system administrators understand how to better protect the assets they manage. I'll focus on the concepts of ethical hacking in order to explain why it's essential in any organization's overall security framework. The tests and procedures I explore should only be executed on your own system or a system that you are charged with protecting. If ownership and responsibility lie with another party, be sure to get clear, written instructions with explicit permission to conduct ethical hacking activities.
Do not investigate individuals, websites, servers or conduct any illegal activities on any system you do not have permission to analyze.
This course investigates the scanning tools and techniques used to obtain information from a target system, including specially crafted packets, TCP flags, UDP scans, and ping sweeps. Lisa Bock discusses how hackers can identify live systems via protocols, blueprint a network, and perform a vulnerability scan to find weaknesses. She also introduces some of the tools and techniques that hackers use to counter detection via evasion, concealment, and spoofing. In addition, learn 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.
