We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 7.0 running on Microsoft Windows Server 2008. IIS 7.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:

This step-by-step article describes how to enable logging for Web sites or for FTP sites in Microsoft Internet Information Services (IIS) 6.0, in IIS 5.0, and in IIS 4.0. You can configure your Web site or your FTP site to record log entries that are generated from user activity and from server activity. Log data can help you control access to content, determine content popularity, plan security requirements, and troubleshoot potential Web site issues or FTP site issues. For example, you can use the log files to help determine whether a security event has occurred. The data in the log files can provide information about the source of the attack.
IIS can save log files to different file formats. When you enable logging, you can specify the file format that you want to use. By default, IIS uses the W3C Extended log file format. Typically, the W3C Extended log file format is the preferred log type to use. This log format lets you configure lots of extended attributes that are useful to help analyze security.
