A proxy is someone who acts on your behalf. In the network, hackers use proxy servers. Proxy chaining is done to provide an extra layer of protection by forcing a TCP connection so that websites do not see your real IP address. Lisa Bock examines using ProxyChains with TOR in Kali to obscure your existence on the network.

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: Our Ethical Hacking series maps to the 18 parts of the EC-Council Certified Ethical Hacker (CEH) exam (312_50). This course maps to the 03 Scanning Networks domain.
