Network security

Network security

1. Fire Wall

   • It allows and prevents different types of data coming in and out.
   • If you didn't have Fire wall you would be able to access any thing and anyone can access something of your computer and websites.

2. Encryption

   • A sentence/word which is scramble it so only people who know how you coded it can uncode it.
   • If you didn't have encryption and you were sending important details to someone on bluetooth people could just see what the details are

3. Passwords

   • Only the user should know the password to keep files safe.
   • If you didn't have passwords people could log onto your user and maybe mess around

4. Physical security

   • A physical way to stop people getting into files.
   • If you did not have physical security people could go onto your devices and just mess around and move/delete files.

5. User access levels

   • The user access levels allow different people to have power over the people on a lower level
   • If they were no different access levels everyone could mess around on different peoples computers
