Dig into The Onion Routing or TOR, an open framework that encrypts and moves traffic within the network. Lisa Bock explores TOR, which enables anonymous browsing, and allows participants to browse freely without fear of being tracked, or having anyone identify their location. View the TOR flow, which is said to be 500 times the public web.
- [Voiceover] The Onion Routing, or Tor,…is an open framework that encrypts…and moves traffic within the Tor network.…Tor enables anonymous browsing,…which allows participants to browse freely…without fear of being tracked…or having anyone identify their location.…Once in Tor a path is chosen through the network.…Tor builds a circuit where each node or Onion Router…is in its path,…knows its neighbors, but no one else.…Here we see it goes to the guard node,…to a relay, then to the exit node,…and then to its ultimate destination.…
On the Tor website they've outlined some strong suggestions…to ensure even safer browsing,…so your identity stays safe.…Even though these suggestions relate to the Tor browser…they could apply to regular browsing.…Things such as don't torrent,…mainly because torrents ignore proxy settings…and make direct connections…even when they're told to use Onion Routing.…Don't install or enable plugins,…such as Flash or QuickTime.…Use HTTPS to ensure private encryption to website.…
HTTPS everywhere is built into the Tor browser…
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.
