It has eliminated the border restriction of obtaining specialized computing resources and expertise that are not available locally to the organizations and individuals without the need to invest in new infrastructure. However, in spite of the immeasurable benefits the technology promises, it has also raised major challenges, particularly as regards its information security and service availability, stressing the need for an elaborate technique of assessing the associated risk of selecting a particular public cloud services provider among available alternatives using the right risk criteria. This paper proposes an expanded multi-criteria risk parameters for the evaluation of public cloud service providers’ associated risk to produce a more accurate results that meets the dynamic nature of the cloud technology.

This is because ZigBee is an open standard lightweight, low-cost, low-speed, low-power protocol that allows true operability between systems. It is built on existing IEEE 802.15.4 protocol and therefore combines the IEEE 802.15.4 features and newly added features to meet required functionalities thereby finding applications in wide variety of wireless personal area networked systems such as home/industrial automation and monitoring systems. Although the ZigBee design specification includes security features to protect data communication confidentiality and integrity, however, when simplicity and low-cost are the major goals, security suffers. This paper gives the general survey of the ZigBee as a wireless sensor network based technology which provides the readers with the general overview of ZigBee network technology including its topology, applicat...
