A firewall is a security system that protects computers and/or networks from unwanted access and threats. It’s like a gatekeeper (or bouncer at a club), that monitors incoming and outgoing traffic based on security rules.
Firewalls can be hardware (like a machine or hardware gateway) or software programs. Firewalls help keep your data safe from hackers, viruses, and other malicious software. When data packets try to enter or leave your network, the firewall checks them to see if they meet safety criteria. If they don’t, the firewall blocks them.
Using a firewall is important because it prevents unauthorized users from accessing your sensitive information.
They can be used to control what websites can be accessed on your network, which is useful for both home and business environments.
We all have come across “Parental Control”. This is just one example of filtering out harmful traffic to children.
Firewalls play a crucial role in maintaining the privacy and security of your data, making them an essential part of and IT security strategy. Whether its just your Router at home, or a Security Gateway at work, its important to ensure its configured correctly for the environment.
