Zero trust architecture (ZTA)

May 2020
trial?

The technology landscape of organizations today is increasingly more complex with assets — data, functions, infrastructure and users — spread across security boundaries, such as local hosts, multiple cloud providers and a variety of SaaS vendors. This demands a paradigm shift in enterprise security planning and systems architecture, moving from static and slow-changing security policy management, based on trust zones and network configurations, to dynamic, fine-grained security policy enforcement based on temporal access privileges.

Zero trust architecture (ZTA) is an organization's strategy and journey to implement zero-trust security principles for all of their assets — such as devices, infrastructure, services, data and users — and includes implementing practices such as securing all access and communications regardless of the network location, enforcing policies as code based on the least privilege and as granular as possible, and continuous monitoring and automated mitigation of threats. Our Radar reflects many of the enabling techniques such as security policy as code, sidecars for endpoint security and BeyondCorp. If you're on your journey toward ZTA, refer to the NIST ZTA publication to learn more about principles, enabling technology components and migration patterns as well as Google's publication on BeyondProd.
