Network Security

1. Firewall

   • A firewall is used to stop data being sent out or recevied by the computor
   • If we didnt have it we would have everyones data in our computor and people will be vunrable as they have peoples private infomation and details in their computor.
   • Firewall is important as it stops information from going out of our computor if the door is closed and if its open the infomation we want to send out will send out.

2. Encription

   • Encription is used to scramble the data being sent over the network so that it cant be read unless you have the key/code to decode it.
