| Install A Firewall
A firewall creates a barrier between your computer and the rest of the Internet to prevent unauthorized access to it. Firewalls can be software applications, hardware devices or a combination of both.
Having a firewall securing your personal computer is a critical component of your personal information protection strategy. Without it, you leave yourself potentially exposed to malicious attacks. Once your firewall is installed, make sure you keep it updated regularly. With some types of software, you can choose to receive automatic updates.
