VoIP Security

Posted by CmdrTaco on from the this-is-the-future-people dept.

An anonymous reader writes "Whitedust are running an interesting article on the security aspects of VoIP. From the article: "The fact that VoIP operates across standard networks makes it vulnerable to all manner of IP hacking - including man in the middle attacks,sniffing, session hijacking, etc." Considering it's recent growth, how secure is VoIP?" PCM2 sent us a wired bit about Phil Zimmerman of PGP working on a privacy system for Voice over IP calling

  1. The Dumbing-Down of America...part XXVII by TripMaster+Monkey · · Score: 5, Informative

    From TFA:
    is an umbrella term used forthesoftware
    some more introductionary information
    Considerating the stability and reliability of the tradional telephony networks
    so it's roll out is most likely inevidable.
    particular relevence to most
    VoIP and it's implementation.
    And all these errors are in just the introduction.

    Now, I don't expect perfection, but the sheer amount of errors present here is beyond the pale, and renders the reader incapable of trusting the subject matter presented, or taking the author seriously.

    Mr. Anderson, about 98% of the errors in your article could have been avoided by the use of a simple spell-checker. Nowadays, people don't actually need to know how to spell, as we have software to do that for us...but you have to actually use the software.

  2. Cain and VoIP Sniffing by Anonymous Coward · · Score: 5, Informative

    There is a program called Cain that can sniff VoIP traffic (as well as other things) and turn it into a wav file if it understands the codec. There is a video on how it works at: http://www.irongeek.com/i.php?page=videos/cainvoip 1

    If you're using VOIP as a transparent replacement to POTS there's no change.

    POTS is wide open to MIM attacks.. in fact anyone with a cheap earpiece can do it - no need for a PC even.

  4. No discussion about this, w/out VoIPsec list by papaia · · Score: 5, Informative

    Please visit the VoIPsec archives, before assuming that any one article could cover it all. There you could find links and comments from some of the most pertinent contributors to this subject.
