Compare with different regulatory event:
On 15 March 2023, the US Securities and Exchange Commission (SEC) proposed new requirements for several market entities to address their cybersecurity risks. In particular, the market entities would include broker-dealers, clearing agencies, major security-based swap participants, the Municipal Securities Rulemaking Board, national securities associations, national securities exchanges, security-based swap data repositories, security-based swap dealers, and transfer agents. The SEC proposal would require market entities to implement policies and procedures that are reasonably designed to address their cybersecurity risks and review the design and effectiveness of their cybersecurity policies and procedures. The proposal also includes new notification requirements that would improve the Commission's ability to obtain information about significant cybersecurity incidents and would improve transparency about the cybersecurity risks that can cause adverse impacts on the securities markets.
