What’s a firewall?
A firewall is a network security system that keeps people from getting into or out of a private network without permission. A firewall is a good security measure, especially for businesses that need to protect private customer information. A common security policy and procedure to protect you and your company is to turn on your firewall.
You can use both hardware and software to make a firewall, or you can use both together. Businesses often use network firewalls to stop people who shouldn’t be on the Internet from getting into private networks that are connected to the Internet. Internet especially need firewalls to keep them safe. All messages coming into or going out of the intranet go through the firewall. The firewall looks at each message and blocks those that don’t meet the security requirements.
