Vulnerability discussion

Web server logging capability is critical for accurate forensic analysis. Without sufficient and accurate information, a correct replay of the events cannot be determined.Determining user accounts, processes running on behalf of the user, and running process identifiers also enable a better understanding of the overall event. User tool identification is also helpful to determine if events are related to overall user access or specific client tools.Log record content that may be necessary to satisfy the requirement of this control includes time stamps, source and destination addresses, user/process identifiers, event descriptions, success/fail indications, file names involved, and access control or flow control rules invoked.

Check content

Review the access log file. If necessary, review the <'INSTALLED PATH'>\conf\httpd.conf file to determine the location of the logs. Items to be logged are as shown in this sample line in the <'INSTALLED PATH'>\conf\httpd.conf file: LogFormat "%a %A %h %H %l %m %s %t %u %U \"%{Referer}i\" " combined If the web server is not configured to capture the required audit events for all sites and virtual directories, this is a finding.

Fix text

Open the <'INSTALLED PATH'>\conf\httpd.conf file. Configure the "LogFormat" to look like the following within the block: LogFormat "%a %A %h %H %l %m %s %t %u %U \"%{Referer}i\" " combined

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
