Flexible Features of Comodo Firewall Pro 3.0

Comodo Firewall Pro 3.0 give the choice of protection levels starts during installation. If you choose Basic, you get a simple personal firewall that protects against attack from outside and controls which programs can access the Internet, much like ZoneAlarm's free firewall. Choosing Advanced turns on the Defense+ feature, which monitors and protects many other critical system resources. Defense+ is similar to the OSFirewall feature found in ZoneAlarm Internet Security Suite 7. Of course, turning on Defense+ means you'll get a lot more queries and notifications from the program.

And Another choice during installation tells the firewall to cut down on pop-up queries by automatically approving any program found in comodo's database of almost a million safe programs. Only a confirmed masochist would turn down that offer. By default, the firewall blocks all unsolicited incoming connections. The installer warns that this will interfere with file-sharing programs, Remote Desktop, and any other applications that require your system to act as a server. If you're a Kazaa fiend, just choose to allow (and monitor) incoming connections.

In another move aimed at reducing unnecessary pop-ups, Defense+ starts off in Clean PC mode, assuming that all programs already on the hard disk are safe. As you use the computer, CFP automatically learns what those programs do and creates rules specifically to allow their actions. That way they'll be allowed to do their jobs even if you later choose a stricter security level. Programs not already present on the hard disk (downloads, programs on removable media, applications launched across the network, and so on) are subject to Defense+'s full scrutiny.

The network firewall module offers a similar set of security levels. In the default Train with Safe Mode, the network firewall allows outbound access for known safe programs and queries the user when an unknown program attempts access. Like Defense+, the firewall has a training mode in which it automatically makes rules to allow all connection activity it observes. If you raise the security level to Custom Policy mode, the network firewall permits only the network activity that's explicitly allowed and won't automatically create any rules. For most users, the default Train with Safe Mode is appropriate.
