Prof. Dr. Christoph Meinel

"Internet Weaknesses and Targets" is based on the lecture "Technical Basics of WWW". The course povides the students an introduction to topics concerning Internet and Intranet security. After starting with some remarks on risk analysis and computer crimes, security weaknesses and targets are discussed in detail. Beside others the following topics are discussed in detail: human factor and technical failures, attacks on accounts and passwords, attacks on Internet protocols, misuse of design and programming errors, weaknesses in common operating systems (Unix/Linux and Windows), targets in the WWW, and current malware. Subsequent to these weaknesses and targets possibilities to detect attacks and intrusions will be explained. The lecture course concludes with a discussion about legal and ethical issues.
