Multilayer firewalls function like packet-scanning firewalls in that they filter out incoming data before it can actually enter the network. The difference is that multilayer firewalls use what is called “dynamic packet filtering,” which involves monitoring the networks’ active connections. Based on those connections, the firewall will assess which packets are safe and can be allowed through. Multilayer firewalls offer a number of benefits in securing networks, but can be expensive to employ.
How do I use a firewall?
There are both hardware and software firewalls. The hardware options are often built in to routers to intercept traffic moving between the broadband router and user devices. Software options are programs that monitor the traffic going in and out of your computer. If you are running a Windows operating system, there is a built-in software firewall that you can access by opening the Control Panel and clicking the Windows Firewall pane.
