Fix Recommendation

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"

Set the "Listen" directive to listen on a specific IP address and port.

Restart Apache: apachectl restart

Check Contents

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"

Search for the "Listen" directive:

# cat /<path_to_file>/httpd.conf | grep -i "Listen"

Verify that any enabled "Listen" directives specify both an IP address and port number.

If the "Listen" directive is found with only an IP address or only a port number specified, this is finding.

If the IP address is all zeros (i.e., 0.0.0.0:80 or [::ffff:0.0.0.0]:80), this is a finding.

If the "Listen" directive does not exist, this is a finding.
