“Web servers are the most exposed servers on the
Internet. In order for clients/ target groups to be able to access
the information provided, web servers must be accessible from any
point on the Internet. In contrast to other public services like
DNS and FTP, the Web is especially tempting for “Crackers”: a
succesful “hack” of a system can be visualized by changing the
appearance of the home page to increase awareness of the hacker’s
presence. Such an occurence can lead to a significant loss of
confidence for a company – and this even more so if sensitive
information like credit card details etc. are filched or even
published.Apart from firewalls, which aim at protecting internal networks
against attacks from the internet, web servers are the second
important field requiring a high degree of security. This article
shows how this can be done on a Linux system within just 45
minutes. Of course, the same can also be done on other operating
systems. Below is an example based on the SuSE Linux 6.4
distributions.The paper is located
