Details
Resource mapping is the process of tying a particular file type to a process in the web server that can serve that type of file to a requesting client and to identify which file types are not to be delivered to a client.
By not specifying which files can and cannot be served to a user, the web server could deliver to a user web server configuration files, log files, password files, etc.
The web server must only allow hosted application file types to be served to a user, and all other types must be disabled.

Solution
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’
Disable MIME types for .exe, .dll, .com, .bat, and .csh programs.
If ‘Action’ or ‘AddHandler’ exist within the ‘httpd.conf’ file and they configure .exe, .dll, .com, .bat, or .csh, remove those references.
Restart Apache: apachectl restart
Ensure this process is documented and approved by the ISSO.
