The domain name system (DNS) continues to have problems after attempts to stop the problem have not fixed the flaw, an online computer magazine has said.

Yesterday, ITPro summed up the last year and a half of DNS difficulties, emphasising that security was still prone to hacking after a study by Dan Kaminsky found an exploit in the system, calling into question the IT governance of several internet service providers.

Since February of last year, it noted examples of major flaws with the DNS system, including a 12-hour shutdown of three of the 13 computers that manage online traffic, as well as a failed attempt by Apple to create a patch to solve the problem this month.

"Users could be sent to malicious sites even if they typed in legitimate addresses and the potential for system-wide problems resulted in an unprecedented multi-vendor effort to create patches for the problem," added Asavin Wattanajantra of ITPro.

Last month, Express Computer Online highlighted the need for software asset management in light of "blended threats" which exploited services such as DNS.

More than half of small businesses (53%) believe that the most important benefit of outsourcing is guaranteed response times for IT support, London based Connect conducted the research in 2007.
