| Abstract | Current security issues like service misuse and fraud are well-known problems of SIP-based networks. To design and evolve effective countermeasures, it is important to know how these attacks are launched in reality. For gathering the required data, a specialized SIP Honeynet System has been implemented and operated since December 2009 which has recorded over 47.5 million SIP messages in total. Over time, based on our Honeypot experiences, we developed essential improvements such as global monitoring of whole subnets, clustering of SIP messages or bidirectional SIP message correlation. In this paper, we first describe these system extensions and demonstrate their benefits. Then we provide an analysis of gathered data which goes beyond pure statistical packet analysis. We identify, analyze and correlate the distinct phases of typical multistage attacks and also provide an example of a full attack sequence resulting in attempts to make Toll Fraud calls via a hijacked SIP account. |

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.
