“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

minutes. Of course, the same can also be done on other
operating systems. Below is an example based on the SuSE Linux 6.4
dis tributions.”
