Network security

1. Firewall

   • This is important so you don't send information that is private to you to someone else.
   • If you didn't have firewall people would be able to get your data when online and there wouldn't be anything to block it.

2. Encryption

   • Is used to scramble data which is sent over a network so it's unreadable unless you have a "key"
   • It is important because if you need to send important information somewhere it scrambles it so it is unreadable.
   • If we didn't have this if you were trying to send your bank details to someone they may be able to intercept it and read your bank details

3. Passwords

   • This is important becasue it can stop people getting into your server room.
   • If we didn't have physical security someone would be able to go into your server room and destroy all of your data.

5. User access levels

   • Different people have different levels of privileges "power"
   • This is important because you don't want a child being able to access an adults information or messing with the network.
   • If we didn't have user access levels everyone would have the same privileges so a child would be able to access and download whatever an adult could which would cause mayhem
