How to Defend Againt VoIP Security Floors
Around nine WiFi VoIP handsets and phones have been put to the test by top security experts, who say that security problems range from potential denial-of-service attacks to more severe issues that allow “deep access” to the handset that lets a hacker read any sensitive information on the phone.
Such threats are inevitable. So whose responsibility is it to forestall them? it has been posited that if we see practices like this grow as these devices get more popular then the manufacturers will only have themselves to blame when the security backlash comes back to haunt them.
VoIP hacking is the contemporary version of war dialing – a strategy of automatically scanning telephone numbers using a modem, frequently ringing all telephone number in a local area to find where computers or fax machines are available, then attempting to access them by guessing passwords.
Still there are actions customers can take to protect themselves. Here’s a list of WiFi VOIP security issues, and some useful ways to protect against them:
Multiple directions of attack:
As the phones get more advanced, so could the points of entry for would be hackers. Email, client Web browsers, Bluetooth, SMS, WiFi, media players, and image viewers could all provide a window of opportunity for hackers. Though users can use open-source and commercial tools to continually test their phones and networks, they’ll ultimately have to rely on vendors to also do effective testing on these VoIP devices.
Targeting phones in public environments:
For example a Bluetooth scanner could be concealed at the entrance to a major public space and be used to steal user data. It may be best to keep Bluetooth and other wireless features swicthed off when not needed.
Rogue access points:
Other than this when at the office or on the road, customers will have to keep their guard up and scan for rogue access points. criminals will set up access points to target specifically WiFi phones in the corporate space as well as at conferences and other places business people like to come together. Decent device authentication and encryption can help provide protection here.
Specific attacks:
Targeted attacks on precise voice-over-wireless networks can also be an issue, although perhaps one that the victims may try to downplay.
