VoIP is a threat to wireless security

Security standards for mobile computing and telephony have recently improved, analyst group Gartner claimed, but while service providers have strengthened the security of mobile internet and email connections, customers are going to have to pay extra for it.

“Security obviously cannot be ignored,” said Nick Jones, a research vice-president for Gartner, “but you can worry less — so long as you are willing to pay, for it security can be achieved.”  Jones said that a variety of advances in areas such as encryption and virtual private networks—- and better management strategies—- were helping businesses secure their networks more effectively.

Jones, who gave a keynote speech at Gartner’s Wireless and Mobility Summit, said that mobile computing was becoming an increasingly important issue for IT bosses to consider.  “Mobility is one of the top priorities for CIOs,” he said.  “If you are a CIO, I hope you have a wireless strategy because your peers will have one.”

The Summit also heard that VoIP products such as Skype were likely to drive down mobile phone costs, as some companies are now encouraging staff to use VoIP for long-distance calls.

Jones, however, warned that VoIP services pose a threat to corporate security because they require some ports on the firewall to be left open, which can give hackers opportunities to penetrate a network.,3800004463,39129635,00.htm
