IAP in Front of a Web Backend: Who Gets Through, How Often They Prove It
Identity-Aware Proxy access to a web backend service: the httpsResourceAccessor binding that decides who gets through (nobody by default), re-authentication every eight hours by the method you choose, the Host header check against your domains, and a troubleshooting link on the denied page. IAP guards the path through the load balancer and no other; the backend must still verify the signed header.

Documentation
gcp-iap-web
Identity-Aware Proxy access to a web backend: the members who may
pass, re-authentication, and the Host header check. Works with
Terraform and OpenTofu (>= 1.6), google provider >= 6.0, < 7.0.
IAP on the backend is a switch on the load balancer; this module is who gets through, and nobody is listed by default.
A session lasts as long as the Google session unless reauth is set; eight hours here.
IAP protects the path through the load balancer and no other.
Verification
Static validation runs tofu fmt, init, validate, tflint and checkov.
This module has not yet had a live test, so it is published as statically
validated with its live test pending and does not carry the live-tested mark.
Usage code & full reference need an account

gcp-firewall-policy
A global network firewall policy exists independently of any network; an association puts it in the path, and a policy with a hundred rules and none governs nobody while rendering as fully configured. enable_logging defaults to false on every rule, so a deny that fires leaves no evidence. Refuses a policy with no network, logs every rule unless told not to, and counts the disabled ones.
gcp-service-perimeter
spec is the dry-run configuration and status is the enforced one - two blocks of the same shape, and a perimeter with only a spec is evaluated on every request, logs violations, and blocks nothing. Empty restricted_services is the other way to have none: the perimeter exists, covers the projects, and governs no API.
gcp-dlp
Sensitive Data Protection on a schedule: an inspection template naming the detectors and a weekly trigger over a bucket or a BigQuery table, sampling ten percent of each file, scanning only what changed since the last run, with findings written to your dataset without the matched values and a summary sent to Security Command Center. A full scan, billed per byte, is accepted by name.
gcp-recaptcha
A key with a testing score returns that score for every assessment, bots included - right for staging and, on a production key, a filter that filters nothing; allow_all_domains lets any site consume your assessments against your quota. Testing mode refused without acceptance, domains required on web keys, invisible scoring by default; only a backend assessment call turns a token into a decision.
gcp-secure-web-proxy
A gateway with no rules allows nothing, and a session matcher of true is an open proxy to the internet; the gateway needs a proxy-only subnet in the region that is yours to make; and without TLS inspection the proxy sees the SNI hostname and nothing inside. Rules built from a URL list of your hosts, allow-all accepted by name only, outputs that say what is allowed and that TLS is not inspected.
gcp-cloud-ids
Creating the endpoint creates no packet mirroring policy, so an endpoint with nothing mirrored is provisioned, billed by the hour, shown with a green check and has never seen a packet. The mirroring policy is created with it and refused when it mirrors nothing. Cloud IDS detects and never blocks; blocks_traffic is an output that is always false.
