Discussion

To identify the type of web servers and versions software installed it is common for attackers to scan for icons or special content specific to the server type and version. A simple request like http://example.com/icons/apache_pb2.png may tell the attacker that the server is Apache 2.2 as shown below. The many icons are used primary for auto indexing, which is recommended to be disabled.

Check Content

Enter the following command:

/usr/local/Apache2.2/bin/httpd –M.

This will provide a list of all loaded modules. If autoindex_module is found, this is a finding.

Fix Text

Edit the httpd.conf file and remove autoindex_module.
