Why most zero-trust architectures fail at the traffic layer
Summary
While many organizations invest heavily in identity and access controls for zero-trust architectures, most implementations fail at the traffic layer. Gaps often exist in how traffic enters and moves through the environment, stemming from inconsistent ownership between teams and overlooked areas like ingress paths, load balancers, and service-to-service communication.
IFF Assessment
This article highlights a common and significant failure point in zero-trust implementations, which is bad news for defenders as it indicates a widespread gap in security effectiveness.
Defender Context
Defenders need to ensure that zero-trust principles are applied consistently across all layers of their architecture, not just identity. This involves scrutinizing ingress points, load balancers, API gateways, and inter-service communication for potential weaknesses.
