Cyberspace (网络空间) is constantly developing and presenting new opportunities, as the desire of businesses to quickly adopt new technologies, such as using the Internet to open new channels and adopting cloud services, provides vast opportunity. But, it also brings unexpected risks and unintended consequences that can have a potentially negative effect.

Hardly a day goes by without news of a new cyber threat. Unfortunately, businesses tend to misjudge how much risk they face from cyber crimes and how quickly this risk can develop. For them, the commercial, reputational and financial risks that go with cyberspace presence are real and growing every day.

So all businesses need to do now is establish cyber security within their organization, right?

Establishing cyber security alone is not enough. Nowadays, it is not very difficult for attackers to break security and stop the overall business system. Preventive measures are not enough to stop them. With the advancement of technology, hackers (黑客) have been changing and developing. So business risk management should include risk resilience (复原力) so that businesses can respond to any damaging cyberspace activity. Cyber resilience helps businesses successfully recover to their pre-attack business processes and business operations.

Building cyber resilience is not easy. A key finding of an authentic cyber-resilience report is that no organization can respond effectively on its own to the threats from cyberspace. Organisations must work together to share intelligence and resources. In this way the quality, usability and authenticity of intelligence will be greatly improved.
