Adopt ? We feel strongly that the industry should be adopting these items. We use them when appropriate on our projects.

We keep hearing about enterprises finding their security badly compromised due to an overreliance on the "secure" network perimeter. Once this external perimeter is breached, internal systems prove to be poorly protected with attackers quickly and easily able to deploy automated data extraction tools and ransomware attacks that all too often remain undetected for long periods. This leads us to recommend zero trust architecture (ZTA) as a now sensible default.

ZTA is a paradigm shift in security architecture and strategy. It’s based on the assumption that a network perimeter is no longer representative of a secure boundary and no implicit trust should be granted to users or services based solely on their physical or network location. The number of resources, tools and platforms available to implement aspects of ZTA keeps growing and includes enforcing policies as code based on the least privilege and as-granular-as-possible principles and continuous monitoring and automated mitigation of threats; using service mesh to enforce security control application-to-service and service-to-service; implementing binary attestation to verify the origin of the binaries; and including secure enclaves in addition to traditional encryption to enforce the three pillars of data security: in transit, at rest and in memory. For introductions to the topic, consult the NIST ZTA publication and Google's white paper on BeyondProd.

Trial ? Worth pursuing. It is important to understand how to build up this capability. Enterprises should try this technology on a project that can handle the risk.

While the fabric of computing and data continues to shift in enterprises — from monolithic applications to microservices, from centralized data lakes to data mesh, from on-prem hosting to polycloud, with an increasing proliferation of connected devices — the approach to securing enterprise assets for the most part remains unchanged, with heavy reliance and trust in the network perimeter: Organizations continue to make heavy investments to secure their assets by hardening the virtual walls of their enterprises, using private links and firewall configurations and replacing static and cumbersome security processes that no longer serve the reality of today. This continuing trend compelled us to highlight zero trust architecture (ZTA) again.

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.
