Vulnerability discussion

Without sufficient granularity of time stamps, it is not possible to adequately determine the chronological order of records.Time stamps generated by the Apache web server include date and time and must be to a granularity of one second.

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. Determine the location of the "httpd.conf" file by running the following command: httpd -V Review the "HTTPD_ROOT" path. Navigate to the "HTTPD_ROOT"/conf directory. Edit 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. Determine the location of the "httpd.conf" file by running the following command: httpd -V Review the "HTTPD_ROOT" path. Navigate to the "HTTPD_ROOT"/conf directory. Edit 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.
