SHIELD overlay Sample Clauses

SHIELD overlay. In the scope of the pilot project the overlay, one of the main innovation, could be addressed at architectural level, by a feasibility study, requirements and specifications. The full implementation of these ideas will be later developed and realized in the project follow up.

SHIELD overlay. The SHIELD project will design and implement overlay security agents which will implement the key composability concept (see Figure 2.3). The security agents will be placed in appropriate network entities to be properly selected according to appropriate criteria which take into account the considered scenario. Each security agent monitors a set of properly selected measurements and parameters taken at any of the three above-mentioned layers (see the arrows labelled as measurements in Figure 2.4). These heterogeneous measurements and parameters are converted by the security agents in homogeneous metadata by extensively using properly selected semantic technologies; the use of homogeneous metadata makes easy the metadata exchange among different security agent (see Figure 2.4). Each security agent, thanks to metadata homogeneity, can aggregate the available metadata (the ones relevant to monitored measurements and parameters, as well as the ones coming from other security agents), in order to deduce aggregated metadata which form the so-called dynamic context.
