| Abstract | The SIP-based VoIP system is build on the IP network, so it is affected by the IP network security problem. SIP-based VoIP system has many security problems because of the security mechanism of VoIP system and other external factors. These effects relate to the following three aspects: confidentiality, integrity and availability. This paper analyzed the mechanism of VoIP system and the components of SIP: SIP UA and SIP network server. The attacks on the SIP system, such as the registration hijacking, impersonating a proxy, denial of service and spam are discussed in detail. At last this paper points out the insufficiency of the SIP security mechanism, including certification attack, DoS attack and spam attack. SIP-based VoIP system involves so many security aspects that relational technology is used to assure the security of SIP-based VoIP system. |

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.
