The GLBA, as it is commonly called based on the lead sponsors and authors of the act, is officially known as "The Financial Modernization Act of 1999." It is specifically focused on PII as it relates to financial institutions. There are three specific components of it, covering various areas and use, on top of a general requirement that all financial institutions must provide all users and customers with a written copy of their privacy policies and practices, including with whom and for what reasons their information may be shared with other entities.

Explanation
ISO/IEC 27018 was implemented to address the protection of personal and sensitive information within a cloud environment. ISO/IEC 27001 and its later 27001:2015 revision are both general-purpose data security standards. ISO/IEC 19889 is an erroneous answer.

Authentication goes a step further than identification by providing a means for proving an entity's identification. Authentication is most commonly done through mechanisms such as passwords.
Identification involves ascertaining who the entity is, but without a means of proving it, such as a name or user ID. Authorization occurs after authentication and sets access permissions and other privileges within a system or application for the user. Proofing is not a term that is relevant to the question.

Reproducibility is the measure of how easy it is to reproduce and successful use an exploit.
Scoring within the DREAD model ranges from 0, signifying a nearly impossibly exploit, up to 10, which signifies something that anyone from a simple function call could exploit, such as a URL.
