36/4630 Hyper-G and security
Peter Lipp, Reinhard Posch
The almost daily presence of the Web in the media has resulted in a tremendous increase of interest and a corresponding increase in network activities. Few new users (and amazingly few of the old ones as well) are aware of the risks and dangers awaiting them. To users, a network often looks like a black box where data goes in and magically pops out somewhere else without being accessible to someone else on its way through. Unfortunately, that' s wrong. Currently, almost all traffic is still transported unencrypted over the network (since the networks themselves do not yet provide such service automatically) and is thus accessible to many requiring only a minimum amount of skill and technical knowledge.
This section identifies threats, covers the basics necessary to understand solutions available and introduces examples of how problems can be avoided in practice.
