| Abstract | As SIP-based VoIP services are expected to slowly replace the traditional PSTN services, SIP servers are becoming potential targets of various attacks, one of which is flooding. In this paper, we argue that whitelist, as a strategy to defend against flooding attacks, can be more effective on a SIP server than a Web server. Since most SIP clients tend to have persistent connections with their server, and a whitelist is relatively easy to maintain. The methodology we propose to build a whitelist is capable of keeping the most comprehensive and up-to-date information about the legitimate SIP clients without any integration with a SIP server. We also study the impact of various attacks on a SIP server, and evaluate the effectiveness of our approach under the most powerful attacks. |

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.
