The MUC:SEC Meetup group is a group of computer security professionals in the greater Munich area who meet to exchange their experiences on handling computer security incidents or just exchange best practices in computer security.
As a member of the computer security community, face-to-face interaction is important in building trust relationships, and this meetup is there to provide this opportunity.
