The BYOD has already posed an increased risk to many business

organizations. With BYOC, employees are installing public cloud services such as Dropbox and iCloud on their corporate desktops and mobile devices.



BYOC introduces additional security threats to the organizations by blurring the boundaries between personal data and business confidential data. This makes the organizations to deman more control on their security policy for access and distribution of corporate information.

Cloud Support of the Internet of Things

and Social Network Applications

1. Smart and pervasive cloud applications for individuals, homes, communities, companies, and governments, etc.

2. Coordinated calendar, itinerary, job management, events, and consumer record management (CRM) services

3. Coordinated word processing, on-line presentations, web-based desktops, sharing on-line documents, datasets, photos, video, and databases, content distribution, etc.

4. Deploy conventional cluster, grid, P2P, social networking

applications in the cloud environments, more cost-effectively.

5. Earthbound applications that demand elasticity and parallelism to avoid large data movement and reduce the storage costs

Concluding Remarks :



Mobile cloud security and big data privacy are facing a trust

dilemma by the general public. Without security assurance,

most users will be reluctant to accept clouds, P2P, social

networks, and IoT apps in the future.



Due to the economies of scale, the cloud providers must have

dedicated teams of security professionals or specialists.

Cloud datacenters must have stronger protection in par of the

military standards.



SMACT technologies (Social, Mobile, Analytics, Clouds, and

IoT) are changing our world, reshaping the human relations,

promoting the global economy, and triggering even some

societal and political reforms in different regions of the world

like it or not.
