Safety and security are two key properties of Cyber-Physical Systems (CPS). Safety is aimed at protecting the systems from accidental failures in order to avoid hazards, while security is focused on protecting the systems from intentional attacks. They share identical goals – protecting CPS from failing. When aligned within a CPS, safety and security work well together in providing a solid foun...

In this paper I have attempted to explain briefly, how enterprise security for Mobile Computing Devices can be achieved in organizations. Enterprise security plans must not only address the data security over the network but also the protection of data at rest on mobile devices like Laptop PCs, PDAs, and Smart phones. The inherent lack of physical access control on mobile devices creates specia...

Security is the major obstacles of the long dreamed vision of cloud computing. The sensitive application data are moved into the cloud data centres and run on virtual computing resources in the form of virtual device. The user concerns about cloud computing is its security. Enterprise data centres, Internet Data Centres (IDC) and service provider’s offer racks and networks, and the remaining de...

The security goals of an organization are realized through security policies, which concern physical security, digital security and security awareness. An insider is aware of these security policies, and might be able to thwart the security goals by combining physical, digital and social means. A systematic analysis of such attacks requires the whole environment where the insider operates to be...

The major challenges facing resource constraint wireless devices are error resilience, security and speed. Even though early work showed the existence of secrecy-achieving codes, security and data reliability are still seen as separate processes in contemporary communication system. Security is therefore confined to higher layers of the protocol stack. This lack of any security measure at the w...

There are many indices for measuring property rights (PR) security. They may be classified into two groups: subjective proxies and objective proxies. Most of the proxies are subjective. One contribution of this paper is introducing a new approach for measuring government expenditures devoted to PR protection. Calculating physical capital within the introduced new approach is another contributio...

there are many evident that people are more interested in walking in attractive urban spaces and inappropriate physical and psychological condition can reduce their presence in a remarkable amount. the current research investigates the influence of physical design and psychological elements and their criteria on selective physical activity and specifically walking in urban public spaces. howeve...
