It can be proven that companies are more likely to loose money if IT-security is neglected. Companies worldwide are facing financial loss day by day due to security-gaps in their IT-infrastructure as demonstrated in several studies all over the world. This thesis concentrates on proving that failures in IT-security indeed raise a companys vulnerability and the risk of lost income. It has been written for everybody who does not know much about IT and IT-security but would like to get some insight into the subject and its relevance for the companys success.
