Toward Smart Moving Target Defense for Linux Container Resiliency
This paper presents ESCAPE, an informed moving target defense mechanism for
cloud containers. ESCAPE models the interaction between attackers and their
target containers as a "predator searching for a prey" search game. Live
migration of Linux-containers (prey) is used to avoid attacks (predator) and
failures. The entire process is guided by a novel host-based
behavior-monitoring system that seamlessly monitors containers for indications
of intrusions and attacks. To evaluate ESCAPE effectiveness, we simulated the
attack avoidance process based on a mathematical model mimicking the
prey-vs-predator search game. Simulation results show high container survival
probabilities with minimal added overhead.Comment: Published version is available on IEEE Xplore at

Cloud Storage and Bioinformatics in a private cloud deployment: Lessons for Data Intensive research
This paper describes service portability for a private cloud deployment, including a detailed case study about Cloud Storage and bioinformatics services developed as part of the Cloud Computing Adoption Framework (CCAF). Our Cloud Storage design and deployment is based on Storage Area Network (SAN) technologies, details of which include functionalities, technical implementation, architecture and user support. Experiments for data services (backup automation, data recovery and data migration) are performed and results confirm backup automation is completed swiftly and is reliable for data-intensive research. The data recovery result confirms that execution time is in proportion to quantity of recovered data, but the failure rate increases in an exponential manner. The data migration result confirms execution time is in proportion to disk volume of migrated data, but again the failure rate increases in an exponential manner. In addition, benefits of CCAF are illustrated using several bioinformatics examples such as tumour modelling, brain imaging, insulin molecules and simulations for medical training. Our Cloud Storage solution described here offers cost reduction, time-saving and user friendliness
