Abstract | A Domain Name System (DNS) is a type of name server that manages, maintains and processes Internet domain names and their associated records. In other words, a DNS server is the primary component which implements the DNS protocol and provisions domain name resolution services to web hosts and clients on an IP-based network. Being a most necessary component for the internet functionality, DNS is vulnerable to many security threats. This poor security of DNS makes it vulnerable to many cyber-attacks which are beneficial for the attackers. Fortunately, implementing an effective technique could detect and mitigate DNS leaks or such related vulnerabilities before catastrophic failures. This work proposed a novel technique for handling DNS attack by making a fractal dimensional analysis to detect NXDOMAIN Response based DNS attack. Fractal Dimensional (FD) analysis is the process of analysing the characteristics and behaviours of network to understand it better. A fractal analysis can be defined as a quantity or a broken geometric object divided into parts each of which can be considered as a reduced-size copy of the entire object. This can have the same statistical characteristics as the whole object. Fractal objects can maintain self-similarity at all levels. It need not display exactly the same structures at all levels, but same type of structures must be ensured at all levels. Since behaviours can be detected using FD, even minor abnormal behaviours in any features of the network can be extracted in a more precise way which is the key point of this research. |

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.
