| Abstract | Internet security systems like intrusion detection and intrusion prevention systems are based on a simple input-output principle: they receive a high-bandwidth stream of input data and produce summaries of suspicious events. This simple model has serious drawbacks, including the inability to attach context to security alerts, a lack of detailed historical information for anomaly detection baselines, and a lack of detailed forensics information. Together these problems highlight a need for fine-grained security data in the shortterm, and coarse-grained security data in the long-term. To address these limitations we propose resource-aware multi-format security data storage. Our approach is to develop an architecture for recording different granularities of security data simultaneously. To explore this idea we present a novel framework for analyzing security data as a spectrum of information and a set of algorithms for collecting and storing multi-format data. We construct a prototype system and deploy it on darknets at academic, Fortune 100 enterprise, and ISP networks. We demonstrate how a hybrid algorithm that provides guarantees on time and space satisfies the short and long-term goals across a four month deployment period and during a series of large-scale denial of service attacks. |

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.
