Security functional requirements
In the CC standard security functional requirements are described by means of functional components. The functional components describe IT issues which refer to the requirements laid down for security functions. There are 11 component classes (see the table below), divided into families. The components are made of elements. Each element presents in detail a given issue from the point of view of information technology. The catalogue of functional components is used for modelling the behaviours of security measures (their functionality).
