| Abstract | A major concern for network intrusion detection systems is the ability of an intruder to evade the detection by routing through a chain of the intermediate hosts to attack a target machine and maintain the anonymity. Such an intermediate host is called a stepping-stone. The intruders have developed some evasion techniques such as injecting chaff packets. A number of algorithms have been proposed to detect stepping-stones, but some of them failed to detect correctly when the network traffic is somehow corrupted or with the chaff packets. We discuss the viability of solving those issues by improving a previous methodology. The algorithm is based on finding as many matched pairs of incoming and outgoing packets on the same host as possible and then decide whether it is a stepping-stone connection by the mismatched rate. We examine a number of tradeoffs in choosing the threshold values by simulating network traffic. Our experiments report a very good performance with very low false detection rates when using carefully selected parameter values. |

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.
