1. Data Interception

   • View traffic moving through a network
   • Using a computer / router
   • Read packets secretly
   • Change the data
   • Packet Sniffer / Packet Analyser
   • How to protect against it
     • Encrypt the network
       • WPA2 - More secure Encryption
       • WEP - Less secure Encryption
     • Use sites that have HTTPS
     • Use a VPN

2. Data Theft

   • Make copies of the data in the packets
   • Data Protection Act
     • If companies get data stolen from them
   • How to protect against it
     • Check that HTTPS is used on a website
     • Companies should only allow people to access the data if it realtes to their job
     • Companies must have policies and training
       • To make sure the data won't get lost / stolen
     • Make sure that any data stored is encrypted

3. Network Forensics

   • Packet Analysers
   • Network Monitering Tools
   • Monitor and analyse computer network traffic
   • To find evidence of crimes / detect attacks
   • Two Methods
     • All data is saved and is analysed later
       • Needs a large amount of storage space
     • All data is analysed whilst it's passing through the network and only important information is saved
       • Needs a fast processor
