Welcome to the website of AG Rechnersicherheit e.V.!

We are a working group of interested students, scientists, teachers, experts from industry and externals who meet regularly and exchange ideas about IT security. In this context, we participate in international IT security competitions, and organize such competitions for beginners and more experienced people. You can also find us at the Long Night of Science.
Since the beginning of 2022 we are a registered club, which is also affiliated as an student club at the TU-Berlin and supported by the department "Security in Telecommunication".

We meet Tuesday every week at Audi3 TEL 20, Ernst-Reuter-Platz MAR Gebäude Room 0.011, Marchstraße 23, 10587 Berlin (see below) from 18:00 - 20:00.

History

In 2006, the working group "AG Rechnersicherheit" was founded as an initiative following the course "Sicherheit in Rechnersystemen" (Security in Computer Systems) under the direction of Sebastian Koch and Jörg Schneider at the department "Kommunikation und Betriebssysteme" (KBS) at the TU Berlin. The main goals of the group are to exchange information about new developments (through weekly meetings) and to participate in international security competitions under the team name "ENOFLAG" or the alias "LEGOFAN" (the usage varies depending on the composition and size of the team). The working group, strongly supported by the KBS department and the SecT department, has participated very successfully in more than 27 international competitions in the last eight years.

Since March 2018, the group is an official student club of the TU-Berlin. This year, the KBS department ceased its activities and the Computer Security group moved to the Security in Telecommunication department.

At the beginning of 2022, the club took the next step and applied for the registration of the club "AG Rechnersicherheit" in the register of associations at the district court Charlottenbrug, Berlin.
