Let us introduce you to another great conference that deserves more recognition!

The Open Security Conference ( @OSCo ) is a people-centred international gathering in Rückersbach (Germany) for everyone interested in cybersecurity.

As an open space, Osco presents a different concept of security conference - literally from the community, for the community. You know, as cool conferences do ;-)

It offers a platform to ease the learning curve in cybersecurity and provides the opportunity to learn, discuss, and teach.

Open Security Conference
Weil OSS eben nicht immer ein System mit Vereinsmeierei und Ländergrenzen ist und nicht jede Library von nem deutschen Verein getragen wird. Und trotzdem wäre es wichtig, dass diese Arbeit gesellschaftlich gewertschätzt wird. Egal wer Träger der Software ist (außer Unternehmen vielleicht). Wenn sie gesellschaftlich relevant im Sinne 52 AO ist, sollte es Anreize geben.

Application security specialist @sydseter mentioned to me this comprehensive web page by @adamshostack listing information security and privacy table-top games, including the card games OWASP Cornucopia @owasp and Digital Benefits and Disbenefits Cornucopia @DBD_Cornucopia

Game on!
