Using Firewall Protection
Firewall protection checks for suspicious activity in communications sent between client computers and
network resources or the Internet.
As the administrator, you can define what constitutes suspicious activity and how firewall protection
responds to:
•
IP addresses and communication ports that attempt to communicate with your computer. You can
specify whether to allow or block communications from other IP addresses on your network or
outside your network, or you can identify specific IP addresses and ports to allow or block.
•
Applications that attempt to access the Internet. You can use McAfee's recommendations for safe
Internet applications, or you can identify specific applications to allow or block. You can also select
firewall protection's response to detections of unrecognized applications.
Firewall protection has two primary modes: users configure firewall settings and an administrator
configures firewall settings. The McAfee default policy is configured to let client computer users decide
which communications and applications firewall protection allows. The administrator setting puts all or
partial control with the administrator.

Frequently asked questions
To ensure the highest level of protection for your network, McAfee
recommends that an administrator configure the firewall protection
settings in one or more policies, which are then assigned to client
computers. When an administrator sets firewall protection, it is
important that the applications and communications that are important
to your users are allowed before deploying the policy. This ensures that
no important communications are blocked.
