97 CHAPTER 20 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, ensure that the computer that you trust is safe. If a computer that you trust is infected through a worm or other mechanism, your computer can be vulnerable to infection. In addition, McAfee recommends that the computer(s) you trust are protected by a firewall and an up-to-date antivirus program also. Firewall does not log traffic or generate event alerts from IP addresses in the Trusted IP Addresses list. Computers that are associated with unknown, suspicious, or distrusted IP addresses can be banned 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 certain an Internet connection poses a specific threat. Ensure that you do not block important IP addresses, such as your DNS or DHCP server, or other ISP-related servers. Depending on your security settings, Firewall can alert you when it detects an event from a banned computer. In this chapter Trusting computer connections 98 Banning computer connections 101
