In May 2017, a tutorial covering the Secure Tropos modeling method conceptualization within OMiLAB was presented at the IEEE 11th International Conference on Research Challenges in Information Science, located the the University of Brighton, UK.
In case you are interested to follow the practical parts of the tutorial with your own modeling tool, please donwload and install the latest version of the Secure Tropos modeling tool which can be found here: http://austria.omilab.org/psm/content/sectro/download?view=download.
