Voice-over-IP Security Concerns

Posted: 19th Sep, 2005 By: MarkJ
Symantec has warned that the growth of Voice-over-IP (VoIP) Internet telephony products has also started to attract hackers:

But routing phone calls via the net makes Voip systems vulnerable to a whole series of security problems, notes the Symantec report.

The growing use of Voip could encourage the emergence of:

* audio spam that clogs voicemail boxes with spoken adverts

* voice phishing that tries to con people into handing over confidential details

* caller-ID spoofing which allows conmen to make it look like they are calling from a legitimate number such as a victim's bank

* call hi-jacking that re-directs calls to conmen and criminals


Denial-of-service (DoS) attacks, which involve bombarding networks with large amounts of data, are also on the increase. Roughly 927 are occurring everyday. More @ BBC News Online.
