| Abstract | All Internet-accessible computing systems are currently faced with incessant threats ranging from simple script-kiddies to highly sophisticated criminal enterprises. In response to these threats, sites must perform extensive intrusion monitoring. This intrusion monitoring can have significant costs in terms of bandwidth, computing power, storage space, and licensing fees. Furthermore, when exploits are detected, the victims must take actions that can consume further resources and compromise their objectives (e.g., by reducing e-commerce server throughput). In this paper, we explore techniques for modeling the costs and benefits of various security monitoring and response actions. Given these models and stochastic expectations about the types of attacks that a site is likely to face, our CIRCADIA (cooperative intelligent real-time control architecture for dynamic information assurance) automatic security control system is able to make real-time tradeoffs between the level of safety and security that is enforced, and the level of system resources/performance that are applied to the main computational objectives (e.g., e-commerce transactions). We show how CIRCADIA is able to dynamically adjust its security activities to account for changing threat profiles and objectives. The result: a continually-optimized balance of security-maintaining activity that reduces risk while still allowing the system to meet its goals. |

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.
