When a connection to the Internet is not needed, disconnect your Internet access in order to minimize the risk of your computer files being hacked into by a cyber criminal. The Internet connection can let a hacker gain access to and control over your computer.

Schools sometimes maintain a server. A proper firewall must be installed to make it more difficult for any hacking activities to take place. It is important to set up and define each user's security settings, rename administrator usernames and passwords, disable any guest accounts, and carefully define the scope of student accounts.
