“…Moreover, the residential environment integrates with other ubiquitous computing applications, like smart metering and e-health, found in the smart home ecosystem. Nevertheless, as said devices typically handle personal sensitive data and often feature direct interaction with the physical world, a key factor in the wider adoption and success of these new technologies will be the effectiveness with which the various security [1] [2] and privacy [3] concerns are tackled. A necessary instrument in successfully addressing these issues is the presence of robust access control mechanisms.…”

Computing devices already permeate working and living environments; a trend which is expected to `ntensify in the coming years. However, the direct interaction smart devices often have with the physical world, along with the processing, storage and communication of private sensitive data pertaining to users' lives, bring security concerns into the limelight. This paper presents Web Service Access Control for devices (WSACd), a framework that combines access control provided by the eXtensible Access Control Markup Language (XACML) with the benefits of Service Oriented Architectures through the use of the Devices Profile for Web Services (DPWS). Based on standardized technologies, it enables fine-grained policy-based management of the heterogeneous embedded devices that may be found in a smart residential setting. The proposed framework is implemented in full and its performance is evaluated on a test-bed featuring devices expected to be found in a typical residential environment.

“…The main characteristics of CPS are: (a) the type of process which is needed to be monitored or controlled and (b) the network of intelligent devices that interconnect with a control system. CPS are currently used in electric power generation, transmission and distribution, monitoring systems, water systems, environments, manufacturing, traffic signals, and mass transport [3]. CPS design encounters difficulties because of the nature of the systems, which are time-critical, embedded, fault tolerant, distributed, intelligent and heterogeneous.…”

Abstract-Cyber-Physical Systems (CPS) appear to be of paramount importance due to their increasing use on critical infrastructure. New challenges have occurred because of the nature and the complexity of such systems in supporting heterogeneous physical and cyber components simultaneously. Failures or attacks on system components decrease system reliability creating severe consequences to CPS and the attached applications. The construction of complex CPS with respect to security and dependability (S&D) properties is necessary to avoid system vulnerabilities at design level. Design patterns are solutions for reusable designs and interactions of objects. In this work we present a pattern-based language for designing CPS able to guarantee S&D properties. The first set of S&D patterns includes the Reliability Component Composition (RCC) Patterns for designing reliable CPS. RCC patterns are encoded in Drools, which is a rule-based reasoning system. To evaluate our approach, we use RCC patterns as a methodology for designing a reliable wireless sensor network attached to a physical architecture to send monitored data to a central controller through relay nodes and paths.
