Abstract | To ensure the protection of computer networks, an intrusion detection system (IDS) should be integrated in the security infrastructure. However, IDSs generate a high amount of false alerts exceeding the administrator ability for analysis and omit several attacks which can threaten the network security. In this paper, a two-stage process based on data mining and optimization is proposed having as input the outcome of multiple IDSs. In the first stage, for each IDS the set of elementary alerts is clustered to create a set of meta-alerts. Then, we remove false positives from the sets of meta-alerts using a binary optimization problem. In the second stage, we discard the meta-alerts generated by all IDSs and only those missed by one, two or most of them are left. This set is called the set of potential false negatives. In fact, at this level a meta-alerts fusion is performed to avoid the redundancy between meta-alerts collected from multiple IDSs. Finally, a binary classification algorithm is proposed to classify the potential false negatives either as real attacks or not. Experimental results show that our proposed process outperforms concurrent methods by significantly reducing the rate of false positives and false negatives. |

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.
