A firewall is a system that is designed to prevent unauthorized access to or from a computer network. It is universally acknowledged as a foundational technology component of a network security strategy. Ideally all communication between your computer and internet would flow through a firewall that lies between your computer network and the Internet. Networks without firewalls are at risk of intrusion from automated or targeted attacks.

Although a firewall can be software or hardware, SCA strongly recommends using a hardware firewall appliance due to the higher level of security features included in a hardware firewall as compared to a software firewall. Using a hardware firewall appliance creates a layer of security at the edge of the network blocking unwanted traffic from entering the network.

Your internet connection leaves you vulnerable to hackers who want to access or damage your financial and personal information. Some hackers may be after your high-speed connection so that they can use it to send malicious viruses to other parts of the internet. Some intrusions have the power to destroy your data, and many then request payment to restore the data (known as ransomware). Other forms of attack include keylogging or phishing attacks that aim to steal usernames and passwords, and webcam and microphone hijacking that are used to film or record private or sensitive information.

A firewall works as a barrier, or a shield, between your computer network and internet. When you are connected to the Internet, you are constantly sending and receiving information. All messages entering or leaving pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria.
