How to fix?
Logging metric filter and alert for Storage IAM permission changes should be configured.
Example Configuration
resource "google_logging_metric" "logging_metric" {
name = "logging_metric"
filter = "resource.type=gcs_bucket AND protoPayload.methodName=\"storage.setIamPermissions\""
metric_descriptor {
value_type = "INT64"
metric_kind = "DELTA"
}
}
resource "google_monitoring_alert_policy" "alert_policy" {
depends_on = [google_logging_metric.logging_metric]
display_name = "Alert Policy"
combiner = "OR"
conditions {
display_name = "condition"
condition_threshold {
filter = "resource.type=gcs_bucket metric.type=\"logging.googleapis.com/user/logging_metric\""
duration = "60s"
comparison = "COMPARISON_GT"
}
}
