Domain matching depends on visible protocol metadata and may not identify all encrypted application destinations. That property alone cannot account for the reported symptom; account-by-account manual security policy edits cannot reliably preserve enterprise-wide coverage.

Volumetric layer-three/four floods require upstream DDoS mitigation beyond individual HTTP pattern rules. That property alone cannot account for the reported symptom; account-by-account manual security policy edits cannot reliably preserve enterprise-wide coverage.

Stateful inspection tracks connection context rather than evaluating packets entirely independently. The decisive technical distinction is AWS Firewall Manager can centrally govern supported network and WAF policies across organization resources; account-by-account manual security policy edits cannot reliably preserve enterprise-wide coverage.

An edge policy controls supported viewer methods and cacheability, separately from origin application logic. The decisive technical distinction is CloudFront supports custom error response mappings and cached error handling behavior; origin error statuses can be mapped to viewer-facing responses without modifying the origin application.

Changing an origin file does not automatically replace copies already cached at edge locations. The decisive technical distinction is CloudFront supports custom error response mappings and cached error handling behavior; origin error statuses can be mapped to viewer-facing responses without modifying the origin application.

Caching responses without segregating identity-sensitive dimensions can disclose one user's representation to another. The reported evidence instead concerns CloudFront supports custom error response mappings and cached error handling behavior: origin error statuses can be mapped to viewer-facing responses without modifying the origin application.

Default flow formats may omit the extra context needed to distinguish transport behavior. That property alone cannot account for the reported symptom; mirroring supports packet-level inspection, unlike flow logs that summarize connection metadata.

Flow records summarize packet flows and disposition rather than full application payloads. The reported evidence instead concerns VPC Traffic Mirroring can copy selected packet traffic to supported network inspection targets: mirroring supports packet-level inspection, unlike flow logs that summarize connection metadata.

A permitted virtual network path can coexist with a crashed application or failed TLS handshake. The reported evidence instead concerns VPC Traffic Mirroring can copy selected packet traffic to supported network inspection targets: mirroring supports packet-level inspection, unlike flow logs that summarize connection metadata.

A healthy NLB can still direct clients to overloaded targets when the target fleet is undersized. The decisive technical distinction is dynamic workloads need target-group membership synchronized with current backend task IPs; target discovery must follow workload life cycle to avoid forwarding to stopped or obsolete tasks.

Service-level private connectivity avoids exposing unrelated provider address ranges to consumers. The decisive technical distinction is dynamic workloads need target-group membership synchronized with current backend task IPs; target discovery must follow workload life cycle to avoid forwarding to stopped or obsolete tasks.

A nominal bandwidth rating alone does not establish packet-processing performance for tiny packets. The reported evidence instead concerns dynamic workloads need target-group membership synchronized with current backend task IPs: target discovery must follow workload life cycle to avoid forwarding to stopped or obsolete tasks.

Participant accounts can use subnet capacity without owning the networking VPC or its route tables. For the stated conditions, full network peering requires nonoverlapping CIDRs, while service endpoints abstract the provider's internal addresses. The more specific mechanism is privateLink can provide private consumer-to-provider application connectivity without requiring nonoverlapping VPC CIDRs.

A routed peer cannot distinguish duplicate destination CIDRs in separate VPCs. The reported evidence instead concerns privateLink can provide private consumer-to-provider application connectivity without requiring nonoverlapping VPC CIDRs: full network peering requires nonoverlapping CIDRs, while service endpoints abstract the provider's internal addresses.

Each peer must route the remote CIDR explicitly; peering does not act as a universal router. The reported evidence instead concerns privateLink can provide private consumer-to-provider application connectivity without requiring nonoverlapping VPC CIDRs: full network peering requires nonoverlapping CIDRs, while service endpoints abstract the provider's internal addresses.

End-to-end confidentiality requires securing both client-to-ALB and ALB-to-target legs when policy demands. For the stated conditions, DNS name resolution is not a transport security control and cannot guarantee TLS use. The more specific mechanism is hTTPS-only viewer protocol configuration blocks unencrypted access even if DNS points to the same distribution.

CloudFront's certificate region requirements differ from those of regional ALB listeners. That property alone cannot account for the reported symptom; DNS name resolution is not a transport security control and cannot guarantee TLS use.

An edge access policy can be bypassed if the origin itself remains publicly readable. The decisive technical distinction is hTTPS-only viewer protocol configuration blocks unencrypted access even if DNS points to the same distribution; DNS name resolution is not a transport security control and cannot guarantee TLS use.

Creating a consumer endpoint is not equivalent to provider consent for private service access. It does not directly achieve the required result: authorized private hosts connect to the endpoint ENI while unapproved clients remain denied. The constraint is that an interface endpoint can be healthy yet unreachable if its ENI security policy drops the client connection.

Service scoping reduces blast radius compared with unrestricted full VPC network connectivity. It does not directly achieve the required result: authorized private hosts connect to the endpoint ENI while unapproved clients remain denied. The constraint is that an interface endpoint can be healthy yet unreachable if its ENI security policy drops the client connection.

Private endpoint DNS behavior is separate from merely establishing the private network interface. In this situation, an interface endpoint can be healthy yet unreachable if its ENI security policy drops the client connection. The proposed change does not ensure authorized private hosts connect to the endpoint ENI while unapproved clients remain denied.

A successful inbound rule does not automatically authorize reply packets under a stateless ACL. That adjustment does not address the controlling condition: application request signatures need HTTP-layer inspection rather than only network ACL port filtering. Verify controlled malicious HTTP payloads are blocked while authorized normal requests succeed.

Packets not sent to the stateful engine cannot be filtered by its configured stateful rules. The needed control instead targets AWS WAF evaluates web requests with managed or custom layer-seven protection rules; it succeeds when controlled malicious HTTP payloads are blocked while authorized normal requests succeed.

Volumetric layer-three/four floods require upstream DDoS mitigation beyond individual HTTP pattern rules. The needed control instead targets AWS WAF evaluates web requests with managed or custom layer-seven protection rules; it succeeds when controlled malicious HTTP payloads are blocked while authorized normal requests succeed.

An interface endpoint can be healthy yet unreachable if its ENI security policy drops the client connection. For the stated conditions, an accepted interface endpoint cannot produce working application data when the provider has no healthy backend. The more specific mechanism is privateLink connectivity depends on the provider's supported endpoint service and healthy backing NLB targets.

Peering creates a potential network path while security policy must separately permit service ports. For the stated conditions, an accepted interface endpoint cannot produce working application data when the provider has no healthy backend. The more specific mechanism is privateLink connectivity depends on the provider's supported endpoint service and healthy backing NLB targets.

AZ placement of attachment subnets affects how traffic from workloads can use the transit hub. For the stated conditions, an accepted interface endpoint cannot produce working application data when the provider has no healthy backend. The more specific mechanism is privateLink connectivity depends on the provider's supported endpoint service and healthy backing NLB targets.

A layer-seven ALB cannot be substituted for a workload whose transport is UDP datagrams. That adjustment does not address the controlling condition: gWLB is designed for appliance insertion rather than content-based ALB routing or general TCP endpoints alone. Verify traffic reaches the inspected destination with the appliance fleet in the intended path.

Static NLB frontend addressing suits IP allowlisting while ALB addresses may change over time. It does not directly achieve the required result: traffic reaches the inspected destination with the appliance fleet in the intended path. The constraint is that gWLB is designed for appliance insertion rather than content-based ALB routing or general TCP endpoints alone.

TCP flow routing and HTTP path matching are separate service capabilities. In this situation, gWLB is designed for appliance insertion rather than content-based ALB routing or general TCP endpoints alone. The proposed change does not ensure traffic reaches the inspected destination with the appliance fleet in the intended path.

Flow-log aggregates are not equivalent to packet captures and omit individual packet payloads. The reported evidence instead concerns CloudFront standard log delivery is asynchronous and may not be real-time for every request: delayed batched logging does not prove requests are absent from the CDN.

The load balancer's status can differ from the response produced or not produced by a backend target. For the stated conditions, delayed batched logging does not prove requests are absent from the CDN. The more specific mechanism is CloudFront standard log delivery is asynchronous and may not be real-time for every request.

Flow records summarize packet flows and disposition rather than full application payloads. The decisive technical distinction is CloudFront standard log delivery is asynchronous and may not be real-time for every request; delayed batched logging does not prove requests are absent from the CDN.
