Description
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. Satisfies: SRG-APP-000246-WSR-000149, SRG-APP-000435-WSR-000148

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. # cat //httpd.conf \| grep -i "Timeout" If the "Timeout" directive is not configured or is set for more than "10" seconds, this is a finding.

Check Text ( C-15469r277025_chk )

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.

# cat //httpd.conf | grep -i "Timeout"

If the "Timeout" directive is not configured or is set for more than "10" seconds, this is a finding.

Fix Text (F-15467r277026_fix)
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"
