Internet Connection Firewall
The Internet Connection Firewall provides basic protection from unauthorized access to the computer while the computer is connected to the Internet. The
firewall is automatically enabled when you run the Network Setup Wizard. When the firewall is enabled for a network connection, the firewall icon appears
with a red background in the Network Connections section of the Control Panel.
Note that enabling the Internet Connection Firewall does not reduce the need for virus-checking software.
For more information, see the Windows Help and Support Center (Microsoft® Windows® XP).
Data Execution Prevention (DEP) Technology
Your computer may include data execution prevention (DEP) technology, which is supported by Microsoft® Windows® XP operating system Service Pack 2
(SP2). The feature prevents the execution of code in memory regions of the computer that are set aside for data storage. When an attempt is made to run
code from an area marked as data storage, DEP helps the computer to detect the action, intercept the code, and raise an exception to prevent the code from
executing. If your computer supports the DEP technology, it is enabled by default for essential Windows programs and services.
For more information about this memory protection technology, see the Microsoft Knowledge Base website. See Microsoft Knowledge Base Article #875352 for
details about the DEP feature.
If you receive a Data Execution Prevention error message in Microsoft Windows XP SP2, see Microsoft Knowledge Base Article #875351.
NOTE: Selecting the connection method This computer connects directly to the Internet enables the integrated firewall provided with Windows XP
Service Pack 1 (SP1) or later.
