Internet Connection Firewall

Description

Windows XP incorporates its own firewall, Internet Connection Firewall (ICF). It watches outgoing requests, and allows replies by Web sites, email servers, etc. It's stealthy, which means it plays dead when it gets a incoming request or reply that does not match an outgoing request. It's a fairly effective firewall, but I sure it's a primary hacking target because it's ubiquitous. Update: Microsoft intends to provide a better version of ICF in the second half of 2004.

How to enable or disable ICF

Windows XP provides very good instructions for enabling or disabling the ICF: Click Start > Help and Support > enter "firewall" in the Search box > click the green arrow > and pick "Enable or disable Internet Connection Firewall" in the search results. You'll probably want to click the "Print" button to get a copy of the instructions that appear.

Or, you can follow my instructions here.

  1. Click "Start" > click "Control Panel" > right-click "Network Connections" and choose "Open". The "Network Connections" dialog box should open.
  2. Right-click your "Dial-up" connection and select "Properties". It will probably have the name of your ISP on it.
  3. Select the "Advanced" -- not Security -- tab in the dialog box that opens.
  4. Check the "Protect my computer and network by limiting or preventing access to this computer from the Internet" option to enable the ICF. Uncheck it to disable the ICF.

You may also want to check the Microsoft article on security, which includes notes on ICF.
