A denial of service (DoS) can occur when the Apache web server is so overwhelmed that it can no longer respond to additional requests. A web server not properly tuned may become overwhelmed and cause a DoS condition even with expected traffic from users. To avoid a DoS, the Apache web server must be tuned to handle the expected traffic for the hosted applications.
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 the "Timeout" directive is specified in the Apache configuration files 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.
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 in the Apache configuration to have a value of "10" seconds or less: "Timeout 10"
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
