The first international workshop on Enterprise Security

as part of CloudCom 2014 (, Singapore, 15-18 December, 2014.


Enterprise security is the key to achieving global information security in business and organizations. Cloud computing is a new paradigm for enterprise where businesses need to be secured. However, this new trend needs to be more systematic with respect to cloud security, which is a factor in sustaining cloud technology by building-in trust. For example, current challenges with cyber security and application security flaws are highlighting important lessons to be learned and also lead to the adoption of best practices. Similarly, as the demand for cloud services increases, the importance of security and privacy will also increase.

One solution is to develop a framework for enterprise security to analyze and model organizational security of the cloud and its data. In particular, cloud data and cloud storage technologies (Amazon s3, drop box, Google drive, etc.) have now become normal practice for almost every computing user. This can explain why building trust for cloud users is one of the main focuses of cloud computing research. On the other hand, the social, human and business aspects of enterprise security are essential to users to keep their skills, business concepts and policies up-to-date. By maintaining all these aspects of security, organizations can develop an enterprise security solution to work together with business models, such as cloud provider enterprise model and cloud consumer enterprise model. In this way, enterprise security can address technical and organizational aspects of security to provide added value and win-win situations for users, adopters and service providers.

By blending technical and organizational aspects of security, our workshop can provide a platform for intellectual discussions and interactions. To highlight the significance of enterprise security and disseminate research contributions in cloud community, we welcome papers addressing technical (implementations, algorithms, experiments, simulation, modeling and prototypes) and organizational (information system related issues, recommendation and best practices, frameworks, risks) issues.

Academic Keynote

Title: Secure Database and Data Mining Techniques for Secure Cloud Data Management and Analytics

Speaker: Dr. Ng Wee Keong

Data security is a widely acknowledged and discussed issue for enterprises migrating their IT systems to the cloud.  The concern is that data confidentiality may be compromised when data is outsourced to a cloud service provider that is unable to technically and legally provide such guarantee.  An intuitive and ideal approach is to encrypt the data before uploading the server and to have the server perform operations on the encrypted data without excessive computational overheads.  What is the state-of-the-art and what are the remaining issues to realize this goal?  This talk provides an overview on two broad groups of work that have been looking at related problems for the past two decades.  The first group looks at supporting encrypted data management supporting store, search, and retrieval of encrypted data in a multi-user setting.  The second group looks at privacy-preserving data mining via the secure multi-party computation approach.  Collectively, both groups provide the much needed data security needs for secure cloud computing.

Academic Keynote 2

Title: Trustworthy Cloud Services by Dynamic Certification

Speaker: Mr. Mario Hoffmann 

In general, cloud service certifications attempt to assure a high level of security and compliance. Cloud services, however, are part of an ever-changing environment. Multi-year validity periods, thus, may put in doubt the reliability of certifications. This talk will illustrate how continuous auditing of selected certification criteria could be achieved by aggregating and interpreting could sensor data in order to assure continuously reliable and secure cloud services and thereby increase the trustworthiness of certifications.

Business Keynote


Title: Cloud Data and Cloud Storage Security Solutions

Speaker: Dr Khin Mi Mi, Aung


Several studies show that Cloud Computing tops the highest increase in IT adoption rate. Enterprises are taking advantage of the efficiencies, flexibilities, and cost-savings made possible by Cloud Computing Environments.  Despite the adoption rate of Cloud Computing, many are still NOT outsourcing their IT workloads in the public cloud. Security remains the top concern in Cloud Computing adoption.  Because data is one of the most valuable assets of any enterprise, outsourcing the processing of this valuable asset is a huge business risk.  The enterprises do not have control of the security of the data once they outsource the storage and processing into the public Cloud.  This talk will address some of the biggest security concerns of enterprises when adopting to the cloud and security solutions for enterprise applications that run in the Public Cloud.
