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.
