These firewalls can use varioussorts ofsignatures and host conditionsto permitor deny traffic. Now when talking about network security, it is of supreme importance to install the right firewall.

If the file or link seems to be malicious, it sends word back to the firewall, blocks the data, and stops it from being downloaded.
