Hackers, or those who endeavour to breach data networks that belong to others, are often smart people. For any data network, security is an issue. No system should be left unprotected and unscrupulous people will always exist who want to take advantage of an unprotected system. In general terms, VoIP systems are relatively secure, but should some determined hacker target your network, then there are a few useful things to know to keep them at bay.


Be prepared
VoIP suppliers today know denmark telegram that the major challenges facing this technology are delivering a reliable service of consistent quality. However, a security strategy is an essential investment. Hacking is one possibility, but VoIP attacks could also take the form of an interruption to service, or Denial of Service, known as a DOS.

just as an email account can be. VoIP spam is called SPIT, or Spam over Internet Telephony. This is probably more aggravation than consternation, but you could come into work to find 20 messages about winning a free trip to Nigeria and somehow all the charges have accrued to you.

Eavesdropping is another potential issue, where unwanted listeners are invading the privacy of your communications. This phenomenon is rather amusingly called VOMIT, or Voice Over Misconfigured Internet Telephony. Needless to say, SPIT and VOMIT are to be avoided.

Not all VoIP systems are the same
VoIP systems can vary a great deal and this means that the security issues affecting them can vary too. As a VoIP system can be customised, security protection systems can be developed to guard the most sensitive elements of the system. For example, staff can have individual VoIP logins that allow access to certain areas of the system only, with the most sensitive data requiring a higher level of access and a more sophisticated method of logging in to this area.
