Network Security

Network Security

1. Fire Wall

   • Is something where nothing can get in or out of devices
   • It blocks people from getting to your files and to stop them from going anywhere
   • Without a fire wall anyone could access your files and delete them

2. Encryption

   • Scrambles the codes so no one can access them
   • Makes it hard for people to read and access them.
   • If we didn't have encryption it would make it easier for people who are trying to hack into you account

3. Passwords

   • Passwords help people not being able to access your files
   • Without passwords you wouldn't be able to have accounts and people would get into your accounts easier
   • Passwords help keep your things safe in a website or on an account

4. Physical security

   • A physical lock e.g. on a door
   • If you had a room full of data and you didn't want anybody to access it you could lock the room.
   • Without having physical security people would be able to go where you store things and basically steal them

5. User access levels

   • If your in a school the students can access their files (stage 1) and the ict teachers can access theirs and ours (stage 2) and people above them can access everyone's files.
   • Without user access levels no one would be able to get anything fixed if it went wrong and they wouldn't be able to mark the work
