Nine out of 10 VPNs not secure

According to a post by vnunet.com, the vulnerability of virtual private networks is generally underestimated.

"A three-year research project by security firm NTA Monitor has concluded that nine out of 10 virtual private networks have exploitable vulnerabilities. Most of the companies that had their VPNs tested as part of the project thought that they were invulnerable to hackers, but researchers found the same types of flaw repeated across the whole product range. The report stated that, in some cases, VPNs were actually the weakest security link in an organisation."

"The most widespread flaw involved the hacking of user names. Many VPNs give away useful information to someone guessing user names."
