The survey, carried out by NetIQ, said that 59 per cent of respondents rated as ‘low’ or ‘very low’ the threat of viruses or worms attacking their VoIP system. Spam over IP and SIP compromises were equally low on correspondents radar, with only 12 per cent and 18 per cent respectively rating these as ‘high’ or ‘very high’ security threats.
While the majority had a firewall in place to secure their infrastructure, less than half had installed security management specifically designed to protect and secure their VoIP system.
NetIQ chief security strategist Ulrich Weigel said: “The survey highlights a worrying complacency amongst organisations which have either already deployed or are about to install a VoIP infrastructure. The main focus for organisations has traditionally been on ensuring voice quality and performance, but vigilance with security, and taking measures such as encrypting voice services and performing regular security audits – is equally important.”
