In Australia, roughly 10 per cent of fixed, and 5 per cent of wireless Internet user IP addresses are compromised, says Barrie Hall, Principal Domain Expert – Broadband, with Telstra Operations.
Presenting to the Internet Industry Association’s (IIA) annual iCode review, Hall also outlined some of the efforts Telstra were undertaking to improve end user safety. The cyber security “war” as he describes it, includes development of a strategy using DNS poisoning to target the alleged 10-15 thousand command and control (C&C) domains globally, to try and cut off the “motherships” controlling vast botnets of unsuspecting end user computers.
Australia is one of the regions with the lowest levels of compromised computers, with some ISPs in South America or the US believed to have significantly higher percentages of computers compromised on some networks. The forum was told Australia has benefited, in part, due to ISPs tending to offer end-users gateway-based connections, ahead of solutions such as bridging modems more commonly adopted overseas.
The IIA iCode forum brings together many of the government, vendor and ISP stakeholders to progress a voluntary code of practice for ISPs to deliver better security and safety for Australian Internet users. iCode is a key program administered by the IIA, and covers approximately 90% of the Australian internet user base.
Although still in its initial phases, the iCode program has attracted global interest, with countries including the US and UK introducing similar initiatives, and others including NZ South Africa and India also monitoring its development.
