Deloitte has opened a Cyber Intelligence Centre in Sydney, offering clients access to a threat monitoring service that is linked to 20 similar centres around the world.The first centre was set up in the United Kingdom in 2013. Financial services companies are the biggest users of the centres, followed by retailers, energy companies and infrastructure businesses.Deloitte's Asia Pacific cyber risk leader, James Nunn-Price, said businesses looking for risks internally by reviewing their systems tended to find things that had already happened.Nunn-Price said: "We are looking externally, we are looking worldwide and we bring learnings from different sectors and actors to our clients."Deloitte works with a few partners. It gets data feeds from groups such as Symantec and RSA."Clients have too much information. We translate a lot of technical data into something clients can do something with. We help them find the hotspots," Nunn-Price said.He said the current hot issue was extortion via denial of service attacks and the use of crypto-lockers.An emerging issue is groups breaching systems and destroying data.Nunn-Price said that when it comes to breach reporting Deloitte follows its clients' policies. However, its advice to clients is that they should report breaches.
