Check content

This check verifies that the personal firewall security level is in compliance. The method of access to the firewall configuration will vary with the actual software. However, in general, the configuration can be viewed by clicking on the program icon in the desktop tray or by using the Programs menu. Navigate to the personal firewall Security Settings configuration window or tab and verify that the security level for both the Local and Internet Zones are set to intermediate setting of “Medium” or higher. The specific default intermediate settings may vary, depending on the vendor firewall used. At a minimum, this level of security should be customized to include the following: - Blocking all Internet access until expressly permitted by the user. - Silently block unused ports. - Block or prompt for usage of Java Applet and ActiveX controls. If the security level is not set to a minimum of intermediate or “Medium” and the above listed minimum settings are not in place, then mark this as a Category II finding.
