| Abstract | A cyber attack modifies the behavior of its target application or system such that it is outside of its intended or desired range of behavior. The challenge is that one cannot predict the attack mechanism that will cause the modified behavior or when and how the target's behavior will diverge. Thus, if one restricts one's sensors to a particular aspect of the system or looks for specific malicious behavior, one is likely to miss the attack. This paper describes an approach for simultaneously examining multiple network and host abstraction layers to discover anomalous behavior and then correlating anomalies to determine whether an attack is taking place and, when applicable, select an automatic response. We have used this approach to implement host-based and network-based intrusion detection systems, HIDAR and NIDAR, for enterprise networks, as well as sister systems for tactical networks. We discuss both the potential performance of the approach and our real-world experiences. In this venue, we focus on our NIDAR experiences in government and corporate networks under both experiments and live operation. |

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.
