Welcome to the second issue of the sixth volume of the journal. In this issue, we publish six papers, as well as a single page per paper incorporating the translation of the title and abstract in Persian, to be used by Persian indexing centers.Thanks to Professor Damiani and his co-authors for their invited paper focusing on \A Risk Model for Cloud Processes", which appears as thefirst paper in this issue.

Key advantages of the methodology include (i) a fully quantitative and iterative approach, which enables stakeholders to compare alternative versions of cloud-based processes; (ii) non-frequency-based probability estimates, which allow analyzing threats for which a detailed history is not available; and (iii) support for quick visual comparisons of risk profiles of alternative processes even when impact cannot be exactly quantified....
