Ensure user customer secret keys rotate every 90 days

ВысокийУровень 1Автоматическаяoci

Описание

Object Storage provides an API to enable interoperability with Amazon S3. To use this Amazon S3 Compatibility API, you need to generate the signing key required to authenticate with Amazon S3. This special signing key is an Access Key/Secret Key pair. It is important to rotate customer secret keys at least every 90 days, as they provide the same level of object storage access that the user they are associated with has. No ACTIVE user may hold a customer secret key created more than 90 days ago (users of the Default identity domain, as listed by oci iam user list). Read-only OCI CLI calls; credentials and home region come from the CLI's normal configuration (~/.oci/config, OCI_CLI_PROFILE, OCI_CLI_AUTH). The tenancy OCID is taken from OCI_TENANCY or the first tenancy= line of the config file. A missing CLI or credential fails the check.

us=$(oci iam user list --compartment-id "$t" --all --query 'data[?"lifecycle-state"==`"ACTIVE"`].id' --raw-output 2>/dev/null) || exit 1
for u in $(printf '%s\n' "$us" | grep -o 'ocid1\.user\.[^"]*'); do
  ks=$(oci iam customer-secret-key list --user-id "$u" --query 'data[?"lifecycle-state"==`"ACTIVE"`]."time-created"' --raw-output 2>/dev/null) || exit 1
  old=$(printf '%s\n' "$ks" | grep -o '"[0-9][^"]*"' | tr -d '"' | awk -v c="$cutoff" '$1 < c')
  [ -z "$old" ] || { echo "customer secret key older than 90 days: $u"; bad=1; }
done
[ "$bad" -eq 0 ] && echo compliant

Ожидаемый вывод: compliant

Как исправляется

Метод исправления: Рекомендация или патч инфраструктуры

Create a new customer secret key (oci iam customer-secret-key create), update S3-compatible clients, then delete the old key.
