increasing the popularity of sip based services (voip, iptv, ims infrastructure) lead to concerns about its ‎security. the main signaling protocol of next generation networks and voip systems is session initiation protocol ‎‎(sip). inherent vulnerabilities of sip, misconfiguration of its related components and also its implementation ‎deficiencies cause some security concerns in sip based infra...

This article provides a comparison of two of the most promising technologies which are supposed to be used for enabling communications over the Internet: IMS and P2PSIP. As their fields of adoptions are totally different – operators and mobile networks for the former, Internet and ephemeral communities for the latter – interoperability rather than competition seems to be the key for achieving a...

The mechanisms which enable the vast majority of computer attacks are based on design and programming errors in networked applications. The growing use of voice over IP (VOIP) phone technology makes these phone applications potential targets. We present a tool to perform security testing of VOIP applications to identify security vulnerabilities which can be exploited by an attacker. Session Ini...

objective(s): this paper aims to investigate synergistic inhibition of polysaccharide from sepia esculenta ink (sip), a newly isolated marine polysaccharide in our laboratory, on breast cancer mda-mb-231 cells exposed to cisplatin. materials and methods: cell viability of mda-mb-231 cells was determined by cck 8 assay. median-effect concentration was analyzed using chou-talalay method that was ...
