| Abstract | Programmable routers are emerging as a promising alternative which facilitates the deployment of new network technologies, for example, software-defined networking; meanwhile, theirs programmability and openness also bring risks of security vulnerabilities. Prior work has concentrated on code security and encryption to improve router action honesty. In this paper, we exploit the feasibility of regulating actions on run-time dataplanes by detecting unexpected packet processing operations, which finally provides an honest and backdoor-proof router to operators. The main challenge is to monitor and regulate the action of router dataplane in dynamic runtime environment. Hence we propose Minos, a framework to regulate router actions on dataplanes. Minos takes Action Identifier (AID) as input to perform lookups in a pre-defined white list called Regulated Action Table (RAT), and it finally verifies that the action is (ab)normal. In the end, Minos achieves a pair of irreconcilable goals for security, i.e., costs and effectiveness. We implement and evaluate Minos on Click and DPDK, separately. And our evaluation results show that Minos captures mal-actions with 2 mega-byte spatial costs and no more than 9% performance loss in both Click and DPDK. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
