Network security

Network security

1. Firewall

   • A firewall opens and closes and lets any data it wants in and out.

2. Passwords

   • Passwords keeps data safe as no one can delete,edit or see data unless they know the password.

3. Encryption

   • Scrambles the data it receives so no one can see the data. The only people who can are the people who scrambled it in the first place.

4. Physical security

   • It's the physical stuff that keeps the data just as safe as before by having fans and locks ect. Like in schools there is normally a small but fairly large room full of lots of fans and computers, data ect.

5. User access levels

   • This only lets certain people/ accounts look at certain things just like in school students are only aloud to look at their own data whereas teachers can look at everyones.
