The technological advances in electronic and software have been rapidly assimilated by computer systems, demanding new approaches for software and systems engineering to provide reliable products, under well-known quality criteria. In this context, requirements engineering has a strategic role in project development. Problems in the elicitation activity contribute to producing poor, inadequate ...

Use cases are widely used for functional requirements elicitation. However, security non-functional requirements are often neglected in this requirements analysis process. As systems become increasingly complex current means of analysis will probably prove ineffective. In the safety domain a variety of effective analysis techniques have emerged over many years. Since the safety and security dom...

New safety critical systems are about to appear in our everyday life: advanced robots able to interact with humans and perform tasks at home, in hospitals, or at work. A hazardous behavior of those systems, induced by failures or extreme environment conditions, may lead to catastrophic consequences. Well-known risk analysis methods used in other critical domains (e.g., avionics, nuclear, medica...
