| Abstract | In its most general form, an attack signature is a program that can correctly determine if an input network packet sequence can successfully attack a protected network application. Filter rules used in firewall and network intrusion prevention systems (NIPS) are an abstract form of attack signature. This paper presents the design, implementation, and evaluation of an automated attack signature generation system called Trag, that automatically generates an executable attack signature program from a victim programpsilas source and a given attack input. Trag leverages dynamic data and control dependencies to extract relevant code in the victim program, accurately identifies variable initialization statements that are not executed in the given attack, is able to generate attack signatures for multi-process network applications, and reduces the size of attack signatures by exploiting responses from victim programs. Experiments with a fully working Trag prototype show that Tragpsilas signatures can indeed prevent attacks against multiple production-grade vulnerable server/Web applications, such as apache, wu-ftpd and MyBullentinBoard, with up to 65% reduction in size when compared with the victim program. In terms of performance overhead, the additional latency as observed from the client-side is no more than 25 usec for multi-process Web applications, while the overall throughput remains unaffected. |

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.
