Cantwell. “They exploited the wiretapping system that our law enforcement agencies rely on under the Communications Assistance for Law Enforcement Act -- known as CALEA. These systems became an open door for Chinese intelligence. Salt Typhoon allowed the Chinese operation to track millions of Americans’ locations in real time, record phone calls at will and read our text messages.”</p>

<p>Not sure what you mean laws but there is certainly regulatory guidance that assessors will be using.<p><i>The agencies consider single-factor authentication, as the only control mechanism, to be
inadequate for high-risk transactions involving access to customer information or the
movement of funds to other parties. Financial institutions offering Internet-based products and
services to their customers should use effective methods to authenticate the identity of
customers using those products and services. The authentication techniques employed by the
financial institution should be appropriate to the risks associated with those products and
services. Account fraud and identity theft are frequently the result of single-factor (e.g.,
ID/password) authentication exploitation. Where risk assessments indicate that the use of
single-factor authentication is inadequate, financial institutions should implement multifactor
authentication, layered security, or other controls reasonably calculated to mitigate those risks.</i><p><a href="https://www.ffiec.gov/pdf/authentication_guidance.pdf" rel="nofollow">https://www.ffiec.gov/pdf/authentication_guidance.pdf</a></p>
