Every year between 2015 and 2020 the ETH IT Security Initiative defined a main theme with 2 or 3 subtopics. The IT security issues presented were (and still are) relevant to everyday life at ETH. The aim of the campaign was to give simple, short and effective tips, tricks and guidelines for secure handling of the own computing resources. But, above all, we wanted to help people to protect the most valuable resource they have... their brainwork.
