Onion routing, Firewalls
1.Now suppose you are browsing the internet using Tor (the onion router) which is a special browser that lets you use the onion routers. You want to access YouTube but you live in China and since YouTube is banned in China you don’t want your government to know that you are visiting YouTube so you decide to use Tor. Your computer needs to contact a particular server to get the homepage of YouTube but it doesn’t directly contact that server. It does that through 3 nodes/servers/routers (these servers are maintained all over the world by volunteers) before that server so that no one can trace back your conversation with that server. What are the steps involved, how does it provide anonymity?
2.Interpret the need for next generation firewall.
3.Do firewall rules have to be symmetric? That is, does a firewall have to block a particular traffic type both inbound (to the protected site) and outbound (from the site)? Why or why not?
4.(i)Compare link and end-to-end encryption.
(ii)Give reasons why SSL certificate is important for your website?
5.Respond to the allegation “WPA fixes many shortcomings of WEP by using stronger encryption; longer, changing keys; and secure integrity checksâ€
