How McAfee Firewall works

McAfee Firewall is a simple-to-operate security tool for the non-technical
users. It dynamically manages your computing security behind the scenes, so
that you do not even have to understand networking protocols. It is custom
created at the moment it is needed, and only as needed, as you go on to do
something else on your computer.
McAfee Firewall filters traffic at the devices that your system uses - network
cards and modems. This means that it can reject inbound traffic before that
traffic can reach vital functions in your PC and before it can waste valuable
system resources.
It monitors applications that are either trusted or not trusted. When trusted
applications need to access a network, it manages everything in the computer
to allow that application's traffic. When it detects non-trusted applications
trying to access a network, it blocks all traffic to and from that application.
Some network communications are needed to maintain network-based
services. These are managed through user defined rules under the SYSTEM
button feature of McAfee Firewall. The default SYSTEM settings feature
provides protection from hostile threats.
In addition, during the installation process, it will prompt you with some basic
questions to set up McAfee Firewall to do specific tasks, according to your
needs (e.g. allow sharing of files or not).
