Web server security: Web server hardening


A web server is not just any other device that you employ in your network environment. Unlike other devices sitting behind layers of defenses and firewalls, web servers sit at the rim of your network and are designed to share information about your organization with the outside world, regardless of who they are.

Also known as the server footer, disabling the server signature prevents the server name, server version number and other information such as recent error messages, module information and other directory information from displaying upon request or when a 404 error (Read more...)
