Network Security

Network Security

1. Firewall

   • A firewall stops different types of data going in and out of your network
   • You need this because anything could get to your computer like something bad like a virus of some sort

2. Encryption

   • This is used to scramble data sent over the network and cant be accessed by anyone else unless you have the ''key''
     • This is important because anyone could see this and it could be confidential to you and something else

3. Passwords

   • Passwords are things that should be kept to yourself and they stop people going on to something that belongs to you
     • Passwords are very important because this keeps your information what could be personal safe

4. User access level

   • This is something that different people can access different levels of network
     • This is important because if you didn't have user access levels anyone could go on anything

5. Physical Security

   • Physical security is doing something physical to protect a network like a backup data and your own data like locking the door so no one can break anything and using air conditioning so the machine for data doesn't overheat
     • You need this because if you didn't protect it someone could just go in and wreck it so no one would have any data
