Network peer authentication cannot independently prove that a particular HTTPS hostname is the intended app server. That adjustment does not address the controlling condition: secure viewer-to-edge traffic does not protect origin traffic when the origin connection remains cleartext. Verify origin requests use validated HTTPS while clients continue using HTTPS to the distribution.

CloudFront's certificate region requirements differ from those of regional ALB listeners. It does not directly achieve the required result: origin requests use validated HTTPS while clients continue using HTTPS to the distribution. The constraint is that secure viewer-to-edge traffic does not protect origin traffic when the origin connection remains cleartext.

HTTPS transport encryption does not establish server identity when its certificate is invalid or expired. It does not directly achieve the required result: origin requests use validated HTTPS while clients continue using HTTPS to the distribution. The constraint is that secure viewer-to-edge traffic does not protect origin traffic when the origin connection remains cleartext.

Layer-seven WAF scope cannot act as a stateful inter-VPC TCP firewall for non-HTTP traffic. In this situation, a GWLB appliance insertion pattern differs from WAF HTTP rules or TCP application balancing. The proposed change does not ensure network paths pass through the healthy inspection appliance fleet during scaling.

Domain matching depends on visible protocol metadata and may not identify all encrypted application destinations. In this situation, a GWLB appliance insertion pattern differs from WAF HTTP rules or TCP application balancing. The proposed change does not ensure network paths pass through the healthy inspection appliance fleet during scaling.

A deployed firewall cannot inspect packets that bypass its endpoint in the routing table. It does not directly achieve the required result: network paths pass through the healthy inspection appliance fleet during scaling. The constraint is that a GWLB appliance insertion pattern differs from WAF HTTP rules or TCP application balancing.

Subnet membership alone is weaker identity than authorized workload security-group membership. In this situation, a broad earlier deny can supersede a later allow despite permissive security groups. The proposed change does not ensure the required private flow reaches the instance and blocked ranges remain denied.

Removing ingress permissions alone does not stop instances initiating outbound connections. That adjustment does not address the controlling condition: a broad earlier deny can supersede a later allow despite permissive security groups. Verify the required private flow reaches the instance and blocked ranges remain denied.

Endpoint private addressing does not automatically enforce least-privilege client access. The needed control instead targets network ACL rules are evaluated in ascending rule-number order with first-match handling; it succeeds when the required private flow reaches the instance and blocked ranges remain denied.

The gateway cannot advertise a nonmatching narrow prefix solely because it was placed in an allowed list. That adjustment does not address the controlling condition: privateLink connectivity should rely on supported endpoint DNS rather than hardcoded ENI addresses. Verify partner API DNS resolves the current endpoint and the private request succeeds.

A route marked blackhole cannot carry IPv4 outbound traffic regardless of instance state. The needed control instead targets interface endpoint replacement can change endpoint-specific DNS names and network interface addresses; it succeeds when partner API DNS resolves the current endpoint and the private request succeeds.

A new attachment ID is not automatically equivalent to an old one for route visibility. In this situation, privateLink connectivity should rely on supported endpoint DNS rather than hardcoded ENI addresses. The proposed change does not ensure partner API DNS resolves the current endpoint and the private request succeeds.

Endpoint private addressing does not automatically enforce least-privilege client access. The needed control instead targets security group egress and ingress permissions are configured independently for new flows; it succeeds when unauthorized new outbound attempts fail while required egress remains permitted.

Domain matching depends on visible protocol metadata and may not identify all encrypted application destinations. It does not directly achieve the required result: unauthorized new outbound attempts fail while required egress remains permitted. The constraint is that removing ingress permissions alone does not stop instances initiating outbound connections.

A broad earlier deny can supersede a later allow despite permissive security groups. It does not directly achieve the required result: unauthorized new outbound attempts fail while required egress remains permitted. The constraint is that removing ingress permissions alone does not stop instances initiating outbound connections.

A technically signed certificate is not trusted unless the verifier has the appropriate CA chain. It does not directly achieve the required result: the ALB serves the new valid certificate and clients no longer see the old expiry. The constraint is that certificate lifecycle and listener deployment are separate operations.

Load-balancer TLS termination could change where mutual authentication occurs. In this situation, certificate lifecycle and listener deployment are separate operations. The proposed change does not ensure the ALB serves the new valid certificate and clients no longer see the old expiry.

Mutual TLS verifies client certificate identity separately from the listener's server certificate. In this situation, certificate lifecycle and listener deployment are separate operations. The proposed change does not ensure the ALB serves the new valid certificate and clients no longer see the old expiry.

Network-layer admission can succeed even when the destination application does not accept connections. That property alone cannot account for the reported symptom; permitted packets can still fail at TLS identity verification before application data is exchanged.

The hub's internal route selection can differ from VPC subnet routes and needs separate evaluation. The reported evidence instead concerns reachability Analyzer tests network configuration, not the certificate trust chain used by an application: permitted packets can still fail at TLS identity verification before application data is exchanged.

Layer-three/four flow metadata cannot reveal encrypted HTTP resource paths. The decisive technical distinction is reachability Analyzer tests network configuration, not the certificate trust chain used by an application; permitted packets can still fail at TLS identity verification before application data is exchanged.

High-level constructs can create network defaults that differ from a specific compliance design if inputs are vague. That property alone cannot account for the reported symptom; an IaC dependency graph cannot create a missing external identifier from an arbitrary string.

Resource creation and cross-account permission grants are separate lifecycle operations. For the stated conditions, an IaC dependency graph cannot create a missing external identifier from an arbitrary string. The more specific mechanism is cloudFormation dependency errors can result from missing referenced network resources and invalid identifiers.

A completed stack records one deployment state rather than permanently locking every operator console. The reported evidence instead concerns cloudFormation dependency errors can result from missing referenced network resources and invalid identifiers: an IaC dependency graph cannot create a missing external identifier from an arbitrary string.

Secure viewer-to-edge traffic does not protect origin traffic when the origin connection remains cleartext. That property alone cannot account for the reported symptom; CloudFront's certificate region requirements differ from those of regional ALB listeners.

A technically signed certificate is not trusted unless the verifier has the appropriate CA chain. That property alone cannot account for the reported symptom; CloudFront's certificate region requirements differ from those of regional ALB listeners.

Modern viewer TLS does not excuse an invalid certificate in the separate origin TLS handshake. For the stated conditions, CloudFront's certificate region requirements differ from those of regional ALB listeners. The more specific mechanism is CloudFront custom HTTPS certificates sourced from ACM generally must be in US East (N. Virginia).

A generic default advertisement cannot replace required more-specific route intent in every hybrid design. The needed control instead targets redundant Direct Connect routing requires physical diversity as well as more than one logical circuit; it succeeds when an isolated conduit interruption leaves the alternate customer-to-AWS path functional.

BGP peer authentication blocks routing establishment when credentials do not agree. In this situation, two links in the same conduit remain subject to a shared cable-cut failure. The proposed change does not ensure an isolated conduit interruption leaves the alternate customer-to-AWS path functional.

A private VIF can terminate at a gateway abstraction without one VIF per VPC when constraints permit. The needed control instead targets redundant Direct Connect routing requires physical diversity as well as more than one logical circuit; it succeeds when an isolated conduit interruption leaves the alternate customer-to-AWS path functional.

End-to-end confidentiality requires securing both client-to-ALB and ALB-to-target legs when policy demands. The decisive technical distinction is CloudFront viewer protocol policies can redirect or require HTTPS for viewer requests; an origin secured by TLS does not protect the client-to-edge leg if HTTP remains allowed.

CloudFront's certificate region requirements differ from those of regional ALB listeners. For the stated conditions, an origin secured by TLS does not protect the client-to-edge leg if HTTP remains allowed. The more specific mechanism is CloudFront viewer protocol policies can redirect or require HTTPS for viewer requests.
