VoIP Darling Skype Divulges Flaws In All Clients: Page 3 of 5

Skype fixed this problem for the Windows, Mac OS X, and Linux clients, but not for Pocket PC. "No patch is yet available," said Skype in the bulletin about Pocket PC. Windows, Linux, and Mac users should download the new client immediately.

On the same day Skype patched the vulnerabilities, the Computing Technology Industry Association (CompTIA) released a survey of small- and mid-sized businesses that put VoIP at the bottom of the trust ladder.

According to the CompTIA's poll, only 48 percent of the businesses surveyed currently trust IP telephony's security. By comparison, 76 percent said they trusted the security of traditional telephone networks and 65 percent said they trusted cabled computer networks.

IP telephony even lagged behind wireless, traditionally a part of the communications infrastructure that raises the most security suspicions: 55 percent of the respondents said they trusted wireless, beating VoIP by 7 points.

Those number don't surprise Gartner's Orans. "Concern over security has grown since the beginning of the year," he said, fueled in large part by the relatively new protocols that VoIP relies on, and their inherent insecurity.
