A versatile code execution isolation framework with security first

Content Provider ACM Digital Library
Author Krude, Johannes Meyer, Ulrike
Abstract In PaaS architectures, code execution needs to be isolated to protect tenants from unauthorized access to their data by other tenants and to protect the host system from any type of intrusion by other tenants. In this paper we propose a simple and lightweight framework that provides such code execution isolation units. All design decisions taken for our framework follow well-established design principles for protection mechanisms, such that in our design we put security first. Our framework uses the process barrier and the seccomp filter mechanism to restrict access to memory and to the system call interface. For access to additional resources a request delegation scheme is used. We evaluate our implementation on a small PaaS example architecture. For plain computations, the applied techniques do not introduce any overhead. In general, setup time for isolation units is negligible and the framework achieves acceptable throughput for broad network access. Our work brings tight and versatile isolation units to current unmodified Linux operating systems.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
