Why most zero-trust architectures fail at the traffic layer
Summary
Most zero-trust architectures fail at the traffic layer, despite strong identity and access controls. Gaps often arise from inconsistent ownership between networking, security, and application teams, leading to permissive entry points and fragmented ingress. The lack of visibility into traffic flow during incidents highlights these critical enforcement failures.
IFF Assessment
The article identifies a common and significant failure point in zero-trust implementations, which can be exploited by attackers to bypass security controls.
Defender Context
Defenders need to focus on securing all traffic entry points and internal communication paths, not just user authentication. Inconsistent enforcement of security policies at the network and application layer can create significant blind spots.
