SB 468 would impose a duty on covered deployers — businesses that deploy high-risk AI systems processing personal information — to develop, implement, and maintain a comprehensive written information security program with administrative, technical, and physical safeguards scaled to the deployer's size, resources, and data holdings. The program must include detailed requirements covering employee designation, risk assessment, training, access controls, encryption, third-party service provider oversight, breach response documentation, and at least annual review. Violations constitute per se deceptive trade acts under the Unfair Competition Law, enforceable by the Attorney General and through existing UCL private enforcement mechanisms. The California Privacy Protection Agency is authorized to adopt implementing regulations. The bill died pursuant to Joint Rule 56 and did not advance.
