For this reason, you may prefer to use an external port scanner, a program
that can connect to your computer through an Internet connection to check
for all open ports, and do it more aggressively than the Active Connections
utility. Here are some example utilities that you can run from your own
computer:
??? Nmap Security Scanner (http://insecure.org/)
??? AATools Port Scanner (http://www.glocksoft.com/port_scanner.htm)
Or, using one of these web sites will allow you to perform port scans right
from your web browser:
??? PC Flank Advanced Port Scanner (http://www.pcflank.com)
??? Open Ports Tool (http://www.yougetsignal.com/openPortsTool/)
Among other things, you can use these services to test the effectiveness of
your firewall. If a port scanner cannot detect any open ports, cannot determine
your computer name, and cannot detect any running services, then
you??™re in good shape!
Web and Email
The Web makes our world simultaneously bigger and smaller; it??™s hard to
imagine computing??”or even a meal??”without a web browser within reach.
It??™s also hard to forget everything that comes along for the ride, such as pop
ups, spam, and the constant reminders that ???your privacy may be at risk.???
Lock Down Internet Explorer
Over the years, Microsoft has fixed dozens of security holes in Internet
Explorer, and if you??™ve been using the Windows Update feature regularly,
you already have the latest and greatest fixes installed.
