Ensure IAM password policy requires minimum length of 14 or greater

高レベル 1自動oci

説明

Password policies are used to enforce password complexity requirements. IAM password policies can be used to ensure passwords are at least a certain length and are composed of certain characters. In keeping with the overall goal of having users create a password that is not overly weak, an eight-character minimum password length is recommended for an MFA account, and 14 characters for a password only account. Every password policy must have min-length >= 14 and min-numerals >= 1 or min-special-chars >= 1. Evaluates every ACTIVE identity domain in the accessible compartments (oci iam domain list) via oci identity-domains. 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.
