Vulnerability discussion

If time stamps are not consistently applied and there is no common time reference, it is difficult to perform forensic analysis across multiple devices and log records.Time stamps generated by the Apache web server include date and time. Time is commonly expressed in UTC, a modern continuation of GMT, or local time with an offset from UTC.

Check content

Review the web server documentation and configuration to determine the time stamp format for log data. In a command line, run "httpd -M" to view a list of installed modules. If "log_config_module" is not listed, this is a finding. Review the "httpd.conf" file. Verify the "LogFormat" directive exists. If it does not exist, this is a finding. Verify the "LogFormat" line contains the %t flag. If %t is not present, time is not mapped to UTC or GMT time, and this is a finding.

Fix text

In a command line, run "httpd -M" to view a list of installed modules. If "log_config_module" is not listed, enable this module. Review the "httpd.conf" file. Determine if the "LogFormat" directive exists. If it does not exist, ensure the "LogFormat" line contains the %t flag.

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.
