Governments concerned about increasingly high-profile cyber-attacks must look past individual suppliers and work with vendors to consider risk in the context of an increasingly global security supply chain, the head of IT security with network supplier Huawei has advised.
Citing the importance of public-private partnerships to evaluate and implement best practice around security protections, John Suffolk— Huawei's global cyber security officer and a previous UK government CIO— said the sheer number and diversity of security solutions being pitched to a market terrified by the spectre of cyber-attack was creating strategic challenges for organisations that just want to protect their data.
Security requirements vary according to individual organisations' policies and exposure, he said, which makes it difficult for potential customers to know exactly how security solutions fit together.
"I never specify what 'good' looks like from a security point of view," Suffolk told CSO Australia after a presentation to audiences at this week's CeBIT conference in Sydney. "It's very hard to do because there's a plethora of standards and best practice. Having policies about this is meaningless because you have hackers that know you haven't patched your server, and they're going to come through your front door."
Despite rapid growth that last year made it the world's second-largest supplier of network equipment, Huawei has struggled to counter growing perception that it is an instrument of the Chinese government, and that its products could compromise institutional security. The company was excluded from participation in Australia's National Broadband Network (NBN) last year on security fears - and offered its source code for inspection as a peace gesture but last month disbanded its local NBN-related business unit.
Arguing that 70% of the components in Huawei equipment come from third parties, most of them overseas suppliers, Suffolk said efforts to boost security by mandating particular equipment were misplaced: "I don't see that as a viable solution, because everyone's components come from around the world," he said. "People rely on free trade, and that's what we should promote and protect."
In the longer term, government organisations will need to continue working through their policies to develop what Suffolk called "a measured sense of requirement" that guides closer collaboration between those organisations and the private-sector suppliers upon which they rely.
This includes not only specifying security standards, policy and manufacturing requirements— for example, auditing a vendor's vulnerability management process—but addressing broader issues around skills pathways, policies for boosting R&D investment, and so on. Australia's dwindling base of IT security experts has been singled out as a significant threat facing the country and is forcing companies like security service provider Earthwave, is forcing many providers to look to import foreign nationals to meet security demand.
