| Abstract | While various network applications are common, attack against them, cause some serious problems. Intrusion detection system (IDS) is one solution to encounter such problems. But IDSes are unable to reactive efficiently in encrypted accesses with encryption protocols, because they can not check the contents of a packet. This paper presents a new approach to detect anomaly behaviors in encrypted accesses with SSH2 protocol to network public servers such as http servers, ftp servers and database servers. In this approach, first the system extracts information from each SSH client, which is consist of transferred data size and time interval between messages. Second, the various actions are identified based on similarity of information. Finally, attacks are detected according to intrusion signatures, generated from the frequency of accesses and specifications of TCP traffic. This system dose not decipher private information, because it detect intrusion only by use of transferred data size and time interval between messages and does not require too many calculations, which are needed in common encrypted traffic analysis methods, before start operation. We show that this system is able to detect various attacks with a high accuracy, by implementing our proposed system on the Snort intrusion detection software and with making use of DARPA evaluation dataset. |

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.
