Title: | Seguridad VoIP: ataques y contramedidas en sistemas de código abierto |
Author: | Carrasco Hiruelo, Antonio |
Tutor: | Rivera Guevara, Richard |
Abstract: | As a result of the many benefits over traditional telephony, companies are increasingly opting to migrate or implement their own voice over IP or unified communications systems. This popularity, combined with the relative ease with which crackers can generate almost immediate economic benefits from attacking these systems, has become a popular target that generates million-dollar losses for businesses. The lack of specialized profiles, both in VoIP with knowledge in security, and, on the contrary, security experts with knowledge in VoIP, generates, on many occasions, environments with insecure configurations and designs thus increasing the probability of being attacked successfully. For all these reasons, we wanted to conduct a study of the state of the art in the context of the security of VoIP environments, more specifically environments that make use of open source software. In order to do this, we wanted to trace a brief history of security in telecommunications to the present day, followed by a taxonomy proposal for the threats to which these systems are exposed, to finally make a compilation and exemplified analysis of the most common current attacks. With this analysis, it has been found that one of the attack vectors studied in the Asterisk platform, did not have a specific utility that could serve as support for the work of an auditor or pentester, so a tool has been developed with functions of exploitation and post-exploitation. To conclude, we have proposed a set of good practices that should be considered in any system of voice over IP supported by the design of an architecture that can serve as a basis for a secure implementation. |
