Common use of SHIELD composability Clause in Contracts

SHIELD composability. In the scope of the pilot project, only the composability of some specific components will be demonstrated, while in a more complete project a general framework for composability could be designed and demonstrated The SHIELD SPD modules will be designed and developed to be seamlessly composable by means of open, dependable interfaces that allow both a static and dynamic composability of SPD functionalities over different application scenarios, to guarantee the agreed level of measured SPD metrics of the overall system. … … As shown in Figure 2.3 the SHIELD SPD modules can be compared to pieces of a puzzle, which perfectly fits each other thanks to common interfaces. Each module implements a SPD technology or a specific SPD functionality, as an example in Figure 2.3 at node level there are two modules: personal node and power node modules. Modules belonging to different SPD layers (node, network or middleware) can be composed statically or dynamically by the SHIELD overlay. Single SHIELD SPD modules can be replaced once the measured SPD metrics do not satisfy the required SPD levels. Indeed the SPD metrics are continuously monitored by the security agents and in case of failure, the security agent reacts discovering, composing and configuring the available SPD modules.
