The recent high-profile hacking of Google's Gmail service and Sony's Playstation gaming network is threatening to slow the take-off of the next big thing in the computing space - the cloud.

Computer companies will need to collaborate to work on addressing security issues to boost confidence in cloud computing, where data and software is stored on servers and accessed via the Internet, especially in the corporate space where the potential market size is much larger than the retail space.
"Many enterprises have reservations about the security of cloud computing because of the multi-tenant architecture and the fact that cloud providers are 'big targets'," said Steve Hodgkinson, IT research director at UK-based research firm Ovum.
"The reality, however, is that the leading cloud providers have a very strong incentive to invest in the latest security technologies and processes -- and will arguably be more secure than most enterprises themselves."
Security is a hot issue in the computing world. Hackers broke into Sony's networks and accessed the information of more than 1 million customers, the latest of several security breaches.
Concerns over security could slow the growth of the market for cloud computing, which is expected to reach $3.2 billion this year in Asia alone from $1.87 billion last year, while the global market could reach $55 billion in 2014, according to estimates by technology research firm IDC.
Analysts and industry experts believe hardware-based security provides a higher level of protection than software with encryption added to data in the servers. Chipmakers are working to build more authentication into the silicon.
"We have to do a combination of mitigating things like building more and more security in the infrastructure," said Boyd Davis, a vice president at chipmaker Intel Corp, speaking at the Computex computer show in Taipei this week.
Intel has been working since the end of last year with software and computer vendors including Fujitsu, Huawei, Cisco, Dell, IBM and Hewlett Packard on a cross-industry initiative aimed at making cloud infrastructure more simplified, secure and efficient.
But one of the problems cloud faces is that it is a fragmented market where many vendors provide different security solutions based on their own standards.
Intel's rival ARM and Advanced Micro Devices are also in the process of embedding higher security in their chips and processors, but working with different partners.
If there was an open standard to follow, it would help the industry to build a much secure cloud system, according to AMD.
"Because if you don't have an open standard, you might do security in a certain way and I might do something that's not compatible, and the applications can't talk to each other," said Manju Hegde, AMD's corporate vice president.
He noted that Apple, set to unveil next week a cloud-based service called iCloud, has its own security because it is a vertical company, but the rest the industry should have an open standard.
Intel's Davis agreed that the lack of an open standard and interoperability are limits to the cloud, but added that the industry would have to strike a balance in an open standard with security or else it would make hackers' work easier.
"Because the definition of secure is tightly held. That's one of the dilemmas we'll face. We'd like to provide more capability to control the workload running on our processors, but the more we do that the more we invite malicious codes in."
