Vulnerability discussion

Apache web server can limit the ability of the web server being used in a DoS attack through several methods. The methods employed will depend upon the hosted applications and their resource needs for proper operation.An example setting that could be used to limit the ability of the web server being used in a DoS attack is bandwidth throttling.

Check content

Determine the location of the "HTTPD_ROOT" directory and the "httpd.conf" file: # httpd -V | egrep -i 'httpd_root|server_config_file' -D HTTPD_ROOT="/etc/httpd" -D SERVER_CONFIG_FILE="conf/httpd.conf" Verify that the "Timeout" directive is specified to have a value of "10" seconds or less. If the "Timeout" directive is not configured or is set for more than "10" seconds, this is a finding.

Fix text

Determine the location of the "HTTPD_ROOT" directory and the "httpd.conf" file: # httpd -V | egrep -i 'httpd_root|server_config_file' -D HTTPD_ROOT="/etc/httpd" -D SERVER_CONFIG_FILE="conf/httpd.conf" Add or modify the "Timeout" directive to have a value of "10" seconds or less: "Timeout 10"

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.
