Resource history captures posture while control-plane event records associate modifications with specific authenticated callers; that addresses auditable private endpoint policy changes, rather than investigation of log-tampering administration events.

CloudTrail records supported network control-plane API calls and actor metadata, unlike per-packet flow logs; this belongs to principal attribution for transit route modifications, while the problem is investigation of log-tampering administration events.

Delivery configuration and IAM authorization must both allow log-stream creation and event publication; this changes authorized publication of VPC flow telemetry, not the necessary investigation of log-tampering administration events.

IPsec protects between network gateways, while application TLS validates the service endpoint and protects data beyond the tunnel termination; this belongs to complementary network-layer and application-layer trust, while the problem is cryptographic confidentiality of hybrid private-line packets.

MACsec encrypts supported Ethernet links, but eligibility and configuration prerequisites differ from universally available IPsec VPN; this changes link-layer confidentiality on supported Direct Connect physical connections, not the necessary cryptographic confidentiality of hybrid private-line packets.

In the network-wide IPsec encryption across corporate connectivity workflow, site-to-Site VPN encrypts network-layer traffic between tunnel endpoints, protecting many routed applications without per-service proxying; the current case needs cryptographic confidentiality of hybrid private-line packets.

TLS termination at the ALB does not guarantee encryption on the second hop; the target connection must independently use HTTPS; this belongs to encryption on both sides of an application load balancer, while the problem is TLS encryption from browser to application ingress.

TLS encryption alone does not establish endpoint identity; browsers validate both trusted issuer and subject name; this changes authenticated browser TLS with valid public trust chain, not the necessary TLS encryption from browser to application ingress.

In the certificate-based client authentication at HTTP ingress workflow, mutual TLS lets the listener validate a client's presented certificate against the configured trust material before HTTP forwarding; the current case needs TLS encryption from browser to application ingress.

The secure-transport condition can reject unencrypted HTTP requests at the resource boundary independently of IAM authentication; this belongs to server-side enforcement of HTTPS for object access, while the problem is encryption on both sides of an application load balancer.

HTTPS-only rejects unencrypted viewer requests rather than silently accepting HTTP access; this changes enforcement of encrypted CDN viewer transport, not the necessary encryption on both sides of an application load balancer.

In the centralized TLS termination for a network load balancer workflow, an NLB TLS listener performs managed handshake termination on the front-end, separate from raw TCP passthrough; the current case needs encryption on both sides of an application load balancer.

A listener cannot be duplicated on the same port and protocol to select certificates by hostname. Raw TCP pass-through leaves certificate presentation to the backend.

DNS records affect how names resolve to endpoints, but they do not configure the TLS listener with separate certificates or perform SNI-based selection during a connection.

Subnet network ACLs match network addresses, IP protocol and ports, not TLS SNI hostnames inside the connection handshake. They cannot choose server certificates.

An NLB does not support ALB-style HTTP Host header routing. The TLS SNI extension, rather than an HTTP listener condition, chooses among certificates associated with an NLB TLS listener.

The NLB selects only from the default and explicitly configured additional listener certificates. A matching ACM certificate is not automatically attached solely because it exists in the account.

An HTTPS listener negotiates TLS with clients using a configured certificate, protecting the client-to-ALB hop; that addresses TLS encryption from browser to application ingress, rather than application-owned certificate and TLS endpoint.

IPsec protects between network gateways, while application TLS validates the service endpoint and protects data beyond the tunnel termination; this changes complementary network-layer and application-layer trust, not the necessary application-owned certificate and TLS endpoint.

In the protected backend network hop for sensitive request payloads workflow, end-to-end transit protection requires consideration of both listener and target segments rather than securing just the public listener; the current case needs application-owned certificate and TLS endpoint.

This produces centralized TLS termination for a network load balancer: An NLB TLS listener performs managed handshake termination on the front-end, separate from raw TCP passthrough; the stem instead tests application-owned certificate and TLS endpoint.

TLS termination at the ALB does not guarantee encryption on the second hop; the target connection must independently use HTTPS; that addresses encryption on both sides of an application load balancer, rather than enforcement of encrypted CDN viewer transport.

The secure-transport condition can reject unencrypted HTTP requests at the resource boundary independently of IAM authentication; this belongs to server-side enforcement of HTTPS for object access, while the problem is enforcement of encrypted CDN viewer transport.

In the HTTPS protection from CDN to custom origin workflow, cloudFront-to-origin TLS is configured separately from viewer TLS, and the origin must support a trusted TLS handshake; the current case needs enforcement of encrypted CDN viewer transport.

The viewer protocol policy controls the client-to-CloudFront hop; it does not repair an invalid certificate presented by the custom origin.

Viewer TLS policy is not the cause. The certificate name mismatch occurs during the CloudFront-to-origin handshake.

The TLS name check rejects the certificate; a longer timeout cannot turn a name mismatch into a trusted certificate.

An NLB TLS listener performs managed handshake termination on the front-end, separate from raw TCP passthrough; that addresses centralized TLS termination for a network load balancer, rather than certificate-based client authentication at HTTP ingress.

An HTTPS listener negotiates TLS with clients using a configured certificate, protecting the client-to-ALB hop; this belongs to TLS encryption from browser to application ingress, while the problem is certificate-based client authentication at HTTP ingress.

In the managed private PKI for internal service TLS workflow, private CA creates organization-controlled certificate hierarchies for internal identities, unlike public certificate issuance tied to publicly validated domains; the current case needs certificate-based client authentication at HTTP ingress.

Private PKI ownership includes lifecycle operations; installing a certificate once is not enough to maintain trustworthy TLS identities; that addresses managed lifecycle of internal certificate credentials, rather than managed private PKI for internal service TLS.

ACM automates issuance and renewal for supported domain-validated public certificates used by compatible AWS endpoints; this belongs to managed lifecycle of publicly trusted service certificates, while the problem is managed private PKI for internal service TLS.

Mutual TLS authenticates both endpoints through certificates, whereas ordinary HTTPS primarily authenticates the server; this changes client identity verification during TLS establishment, not the necessary managed private PKI for internal service TLS.

Site-to-Site VPN encrypts network-layer traffic between tunnel endpoints, protecting many routed applications without per-service proxying; that addresses network-wide IPsec encryption across corporate connectivity, rather than managed lifecycle of publicly trusted service certificates.
