With more than 67% of web servers running Apache, it is by far the most widely used web server platform in the world. Apache has evolved into a powerful system that easily rivals other HTTP servers in terms of functionality, efficiency, and speed. Despite these impressive capabilities, though, Apache is only a beneficial tool if it's a secure one. To be sure, administrators installing and configuring Apache still need a sure-fire way to secure it--whether it's running a huge e-commerce operation, corporate intranet, or just a small hobby site.
