Such communications cover most vital infrastructures, including hospitals, ministries, police, army, banks, public bodies/authorities, companies, industries and so on. The purpose of this paper is to raise awareness in regards to security and privacy threats present in private communications, helping both users and vendors safeguard their systems.
This article provides an introduction to private branch exchanges (PBXs) and private communications, and a review of relevant threats and vulnerabilities. Finally, one possible approach to assessment of private communications security is presented, along with appropriate taxonomies. Such approach relies on performing gap analysis and is based on the IMECA technique.

Even if the core public network is operating normally, unintentional or targeted damages and attacks in PBXs can cause significant instability and problems. Furthermore, interception of calls is a very sensitive issue that affects all of us. In that sense, it is not an exaggeration to state that PBXs are part of a nation’s critical infrastructure. Much has been said and done regarding data communication security but PBXs have been left unprotected, forgotten and waiting to be attacked. This contribution outlines a targeted, centralized project in order to both educate the users and secure their telephony systems. It compromises of educational, policy, auditing, technical, documentation, hardware and software solutions and actions that could be implemented under a joint project.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue></record></records></xml>
