On May 24, the Oregon Governor signed SB 684, which amends the state’s data breach notification provisions related to third-party vendors. Among other provisions, the amendments require vendors that are contracted to maintain or access personal information on behalf of a covered entity to (i) notify the covered entity “as soon as is practicable but not later than 10 days” after discovering a security breach or believing a breach has occurred; and (ii) notify the state Attorney General if a security breach involves personal information of more than 250 consumers, or an undetermined amount of consumers, provided that the covered entity has not already done so. SB 684 also updates the definition of personal information to include usernames in combination with other authentication factors used to access a consumer’s account, and establishes that a covered entity or vendor may “affirmatively defend” against allegations it has not adequately safeguarded personal information by showing that it maintained reasonable security measures for protecting personal information in compliance with HIPAA or the Gramm-Leach-Bliley Act, as applicable. The amendments take effect January 1, 2020.
