VOIP LEFT VULNERABLE TO HACKERS

Security company Scanit blames the vulnerability of sensitive data sent using voice over Internet Protocol (VoIP) on inadequate network security, leaving 7 of 10 calls open to wiretapping.

Scanit's audit of data transfer at call centers and service providers pinpointed the main cause--assumptions that VoIP vendors on the network had already installed security measures.

According to Scanit engineer Sheran Gunasekera, "Administrators at these places lacked adequate skills and understanding of the security aspects of setting a VoIP network up.

They relied on the vendor or system integrator to secure it." He said that many networks were running VoIP without encryption.
