California Bill Would Mandate Expedient Software Updates for Credit Bureaus
Following the Equifax data breach in 2017, there has been heightened awareness surrounding how credit reporting agencies handle consumers’ personal information. At the same time, recent high-profile attacks, such as the “WannaCry” ransomware attacks, have focused media and regulatory attention on vulnerabilities associated with unpatched systems. In response to these two concerns, on January 10, a bill was introduced in the California legislature that would amend existing law regulating the cybersecurity practices of consumer credit reporting agencies (CRAs) specifically as they relate to vulnerability patching.
AB 1859 would add provisions requiring CRAs to update software vulnerabilities in certain circumstances. Namely, if the CRA knows or reasonably should know that one of its computer systems is subject to a vulnerability and knows or reasonably should know that a software update is available to address that vulnerability, the CRA must apply the software update expediently, “in keeping with industry best practices,” but in any case within 10 days after becoming aware of the vulnerability and the available software update.
The bill would also create a private right of action for California residents whose personal information was acquired by a breach caused, in whole or in part, by a violation of the software update provisions described above. Moreover, it would allow residents to recover civil penalties for “willful, intentional, or reckless” violations of the software update provisions.
At first blush, by mandating a particular security practice in one specific industry sector, the language of AB 1859 appears to be a departure from the traditional risk-based regulatory approach that encourages organizations to adopt “reasonable” security best practices tailored to their cyber risks without mandating more specific cybersecurity requirements. Notably, however, in 2016 the California Office of the Attorney General adopted a more prescriptive approach to regulating the cybersecurity practices of companies doing business in California. Specifically, in its 2016 Data Breach Report, the Attorney General stated that the list of twenty Critical Security Controls (“CSC”) developed by the Center for Internet Security (“CIS”) “define a minimum level of information security” that all organizations that collect or maintain personal information about California residents should meet. Most importantly, in light of the requirement under California law to implement and maintain reasonable security practices, the report stated that a “failure to implement all the [c]ontrols that apply to an organization’s environment constitutes a lack of reasonable security.” See 2016 Data Breach Report (emphasis added). Included among the CSC controls is Control 4, “Continuous Vulnerability Assessment and Remediation,” which requires regular scanning for vulnerabilities and the adoption of proactive patching processes. Moreover, California law already provides a private cause of action for damages by customers injured by a company’s failure to “implement and maintain reasonable security procedures and practices” in violation of California Civil Code Section 1798.81.5.
The bill is currently set for hearing in committee on February 10.
