Cyber Security for Cyber Physical Systems of Oman

Cyber Physical Systems (CPS) is combinations of different embedded subsystems, which work independently of each other and interact with the environment. Embedded systems operate in the presence of inherent uncertainty, context dependencies and adversarial certainty. In the physical world of embedded systems, all operational environments (Cyber, Physical) are adversarial whether by incident or by users, by natural adversaries or by combination of these. In our research we have identified the key area which is lack of trust and security among cyber physical systems, although there are many security approaches and methods which are available and implemented globally in order to secure CPS, unfortunately none of them discusses the issue of trust based secure CPS particularly in Oman. Other related issues were social engineering, security standards, vendor control, as well as access control implantation were important to study in regards to CPS in Oman. Thus, in order to achieve trust among Cyber Physical Systems we have proposed a two tier blanket approach for achieving the trust among Cyber Physical Systems, and our proposed approach mainly consists of internal and external layers of trust. In particular we will apply our proposed approach to test based simulated environment, for which we will use simulated data. Moreover, we will visit the available Cyber Physical Systems such as SCADA and power grids. Based on our findings and results we will recommend our approach to real time system implementers, who implements Cyber Physical Systems and we believe future Cyber Physical Systems will be secure and trust oriented.
