A pre-release version of the upcoming NeSSi² open source release has been published. This release is only available to students that registered to the class "Absicherung von Dienste".

This semester the class introduces XML application firewalls. Students are tasked to develop NeSSi² plug-ins for XML application firewalls, regular web service clients and attackers on the offered web services.
