89 CHAPTER 18 Managing computer connections You can configure Firewall to manage specific remote connections to your computer by creating rules, based on Internet Protocol addresses (IPs), that are associated with remote computers. Computers that are associated with trusted IP addresses can be trusted to connect to your computer and those IPs that are unknown, suspicious, or distrusted, can be banned from connecting to your computer. When allowing a connection, make sure that the computer that you trust is safe. If a trusted computer is infected with a worm or other mechanism, your computer can be vulnerable to infection. Also, McAfee recommends that the computer you trust is protected by a firewall and an up-to-date antivirus program. Firewall does not log traffic or generate event alerts from trusted IP addresses in the Networks list. You can ban computers that are associated with unknown, suspicious, or distrusted IP addresses from connecting to your computer. Since Firewall blocks all unwanted traffic, it is normally not necessary to ban an IP address. You should ban an IP address only when you are sure that an Internet connection is a threat. Make sure that you do not block important IP addresses, such as your DNS or DHCP server, or other ISP-related servers. In this chapter About computer connections 90 Banning computer connections 94
