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. • A pplications 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. NOTE: 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.
