Duncan Maidens, Raspberry Pi Foundation
This session will introduce a set of 9 animations which can be used to supplement the teaching of basic networking principles such as serial transmission, network topology, Ethernet frames (encapsulation), hubs and switches. We then use Cisco’s Packet tracer Software (free to schools) to teach computer networking concepts such as IP addresses, DNS, URL, frames and packets, port mapping, redirection and rouge hotspots in the context of hacking a network.
Brief videos of the session are at:-
1. Basic sniffer capturing ftp usernames and passwords https://youtu.be/cUtpmdoMhFk
2. Hacked web page with URL misdirecting to fake web sites https://youtu.be/PyocjtCPA1k
3. Rogue Hot spot taking cafe customers and directing them to a rogue DNS server from which www.mybank.com URL are misdirected. https://youtu.be/HM-6DeUBQG0
Relevant Key Stages: KS3, KS4
