State Issues

Recently, NYDFS issued an industry letter to regulated entities advising that a covered entity may adopt the cybersecurity program of an affiliate. New York’s Cybersecurity Regulation (23 NYCRR Part 500) requires regulated entities (Covered Entities) to implement risk-based cybersecurity programs to protect their information systems as well as the nonpublic information maintained on them. (See continuing InfoBytes coverage on 23 NYCRR Part 500 here.) Specifically, 23 NYCRR Part 500 allows “Covered Entities to adopt ‘the relevant and applicable provisions’ of the cybersecurity program of an affiliate provided that such provisions satisfy the requirements of the Cybersecurity Regulation.” NYDFS is also permitted to fully examine the adopted portions of the affiliate’s cybersecurity program to ensure compliance, even if that affiliate is not covered or regulated by NYDFS otherwise. Covered Entities are reminded that while they may adopt an affiliate’s cybersecurity program in whole or in part, the Covered Entity may not delegate compliance responsibility to the affiliate, and is responsible for ensuring it cybersecurity program complies with 23 NYCRR Part 500, “regardless of whether its cybersecurity program is its own or was adopted in whole or in part from an affiliate.” Additionally, a Covered Entity’s compliance obligations are the same whether it adopts an affiliate’s cybersecurity program or implements its own cybersecurity program. Among other things, Covered Entities are required to provide, upon request, all “documentation and information” related to their cybersecurity programs, including evidence that an adopted affiliate’s cybersecurity program meets the requirements of 23 NYCRR Part 500. At a minimum, NYDFS requires access to an affiliate’s “cybersecurity policies and procedures, risk assessments, penetration testing and vulnerability assessment results, and any third party audits that relate to the adopted portions of the cybersecurity program of the affiliate.” NYDFS also explained that foreign bank branches and representative offices often have head offices located outside the U.S. that are not directly regulated by NYDFS. For these entities, all documentation and information relevant to the adopted portions of their head offices’ cybersecurity programs must be provided to NYDFS examiners to evaluate the Covered Entities’ compliance with 23 NYCRR Part 500.
