Reasons to have a Firewall

In this section, you will learn the reasons to have a firewall.

A firewall is a security system that protects your computer from unwanted access. The firewall is typically installed on your computer in order to protect it against malicious attacks such as viruses and malware. A firewall can also be installed on a router or other network device in order to protect the entire network from malicious attacks.

A firewall is an important security measure for both personal computers and networks because it prevents unauthorized access to your information by outsiders.
