| Abstract | A pattern matching method (signature-based) is widely used in basic network intrusion detection systems (IDS). A more robust method is to use a machine learning classifier to detect anomalies and unseen attacks. However, a single machine learning classifier is unlikely to be able to accurately detect all types of attacks, especially uncommon attacks e.g., Remote2Local (R2L) and User2Root (U2R) due to a large difference in the patterns of attacks. Thus, a hybrid approach offers more promising performance. In this paper, we proposed a Double-Layered Hybrid Approach (DLHA) designed specifically to address the aforementioned problem. We studied common characteristics of different attack categories by creating Principal Component Analysis (PCA) variables that maximize variance from each attack type, and found that R2L and U2R attacks have similar behaviour to normal users. DLHA deploys Naive Bayes classifier as Layer 1 to detect DoS and Probe, and adopts SVM as Layer 2 to distinguish R2L and U2R from normal instances. We compared our work with other published research articles using the NSL-KDD data set. The experimental results suggest that DLHA outperforms several existing state-of-the-art IDS techniques, and is significantly better than any single machine learning classifier by large margins. DLHA also displays an outstanding performance in detecting rare attacks by obtaining a detection rate of 96.67% and 100% from R2L and U2R respectively. |

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.
