Zero Trust architecture: a paradigm shift in cybersecurity and privacy

Raymond Teo Cyber Leader, South East Asia Consulting, PwC Singapore 28 Oct 2021

Are your cybersecurity resources and capabilities stretched to the limit?

Hardly surprising given the growing attack surface driven by the digital transformation and remote workforce giving rise to sophisticated cyber-attacks and the increasing complexity of data protection and cyber regulations. A Zero Trust architecture makes smarter use of your resources to strengthen your cybersecurity posture and better protect your data and enable you to concentrate on your business.

Keeping your cyberspace safe is an increasingly costly and thankless task. Rather than fighting the symptoms, it makes more sense to address the root cause: your IT security architecture. Instead of enforcing security controls at the network perimeter, why not adopt a zero trust approach by introducing micro-perimeter step by step starting with the most valuable data in your organisation? Regardless of data location and sourcing model in use, your organisation need to ensure appropriate data protection are in place and effective. Zero Trust means that sensitive data is first identified, validated and than placed in a dedicated data enclave to apply the protection level required by regulation and the threat scenarios applicable for your organisation. This approach allows to deliver transparency who accesses data from where how and when. Such information is the basis to detect anomalies or suspicious behaviour and to make use of automation, machine learning and threat intelligence. 

Because security is no longer enforced at the perimeter only, Zero Trust protection extends beyond your own data centres to cloud, web services and IT services outsourced to a provider. This makes it a great way of modernising network security for a modern, mobile, digital workforce and cloud services.

Some have inhibitions about Zero Trust because they see it as time-consuming and complex to redesign the security architecture. But if we continue to do just more of the same by considering cyber security controls in silos, we will not be able keep up with the increasing cyber threat landscape. 

In this white paper we take the mystery out of Zero Trust with a detailed look at the approach and the six logical steps involved in implementing it. Read why you – and the people who rely on you to protect their data – will be glad you embraced the new Zero Trust paradigm.
