Modern day distributed systems are driven by the need to support data-intensive applications in research fields such as bioinformatics, healthcare, particle physics, and material science. These applications are often multi-domain in nature where they rely on multi-institutional distributed resources that are remotely accessible (e.g., scientific instruments, supercomputers, public clouds) to augment local resources. Provisioning of such resources (often federated) has been traditionally based on applications’ performance requirements that often ignores applications’ data privacy requirements and come into conflict with the (resource) usage and security policies at remote domains. This leads to applications’ data privacy violation and unexpected performance bottlenecks resulting in a lack of trust between the resource providers and application users that in turn causes barriers in wider adoption.
This talk will detail my NSF funded project that aims to augment traditional distributed resource provisioning strategies through novel schemes for formalizing end-to-end security requirements to align security posture across multi-domain resources with heterogeneous policies. The talk will present ‘OnTimeURB’ resource brokering framework that fosters secure and trustworthy data-intensive science collaboration in bioinformatics and health information sharing across multiple domains by defining, formalizing, and implementing security specifications along an application’s workflow lifecycle stages. This talk will also outline my current and future projects that seek to solve unique cyber security and system design challenges.
