How McAfee Firewall works
McAfee Firewall is a simple-to-operate security tool that dynamically
manages your computing security behind the scenes.
Setup
During the installation process, the Configuration Assistant prompts you with
basic questions to set up McAfee Firewall to do specific tasks – according to
your needs (e.g. allow sharing of files or not).
Operation
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 computer and waste valuable system
resources.
McAfee Firewall – the Gatekeeper
When McAfee Firewall is running, it monitors trusted and untrusted
programs that communicate using the Internet. If a trusted application
attempts to communicate, McAfee Firewall allows the program to function
without restrictions. If an untrusted program attempts to communicate into or
out of your computer, McAfee Firewall blocks the program’s attempt to
communicate via the Internet.
Configuration
Some network communications are needed to maintain network-based
services. These are managed through user defined rules under the system
settings of McAfee Firewall. The default system settings feature provides
superior protection from hostile threats.
