Web Application Server Security
The web server is the central part of any web-based application or marketing site. The Apache Web Server is normally placed at the edge of the network hence it becomes one of the most vulnerable services to attack. Using the default configuration may supply sensitive information which can help a hacker to attack your web server.
A badly configured Apache web server or one that is not hardened properly will expose your to significant risk. It’s critical to harden your web server configuration but the Apache configuration system is notoriously arcane and difficult to get right.
