Network Security

Network Security

1. FireWall

   • Allows and prevents data getting in and out
   • If you didn't have a firewall we could connect to anything but anything would be able to connect to us
     • CONSEQUENCES OF NO FIREWALL: Anybody could access what you are doing and mess it up

2. Encryption

   • Scrambles up data so only certain people can get the data
     • Creates a code so only the people who know the code can access the file they want shared/has been shared
       • CONSEQUENCES OF NO ENCRYPTION: Anyone would be able to read what the code is and hack it

3. Passwords

   • Keeps files and user's desktop safe
     • CONSEQUENCES OF NO PASSWORD: People can go into your account and change you work, desktop or even delete files
   • Keeps people from annotating people's work and moving files/ changing the layouts

4. Physical Security

   • Physical way to stop people getting into important files and data such as security cameras and locked doors
     • CONSEQUENCES OF NO PHYSICAL SECURITY: Not having any physical security can lead into vandilism of networks which could lead into having no memory on the computer and loss of networks

5. User access levels

   • You can only access certain things if you are a certain person EG: If you are a student you can't access something's the teachers can
     • STUDENTS: Get access to only their files
       • TEACHERS: Get access to their files and the students files
         • ICT TECHNICIANS: Get access their files, the teachers files and the students files
