WHAT ARE SEC & FINRA CYBERSECURITY RULES?
The SEC and FINRA have moved cybersecurity from guidance to enforceable obligation.
The U.S. Securities and Exchange Commission (SEC) and the Financial Industry Regulatory Authority (FINRA) have progressively elevated cybersecurity from a best-practice recommendation to a formal regulatory requirement for registered investment advisers (RIAs), broker-dealers, investment companies, and other SEC-registered entities. Sacramento-area financial advisors, wealth management firms, and broker-dealers that are registered with the SEC or are FINRA members face cybersecurity obligations that go beyond GLBA and FTC Safeguards — and that are actively enforced through examination and enforcement actions.
The SEC’s 2023 cybersecurity rules for public companies and registered advisers marked a significant escalation: mandatory incident disclosure, board-level cybersecurity governance requirements, and specific controls documentation obligations. FINRA’s cybersecurity requirements flow through its Rules 4370 (Business Continuity), 3110 (Supervision), and examination priorities that consistently identify cybersecurity as a top-tier risk area. For Sacramento-area firms, these are not theoretical federal concerns — they apply directly to day-to-day operations.

KEY SEC CYBERSECURITY RULES
The specific requirements registered firms must satisfy.
SEC Regulation S-P (Privacy of Consumer Financial Information)
Reg S-P requires registered broker-dealers, investment companies, and investment advisers to adopt written policies and procedures to protect customer records and information, and to provide customers with privacy notices. The 2024 amendments to Reg S-P added a mandatory breach notification requirement: firms must notify affected individuals within 30 days of a breach of ‘covered data’ — the most specific timeline in the securities regulatory stack.
SEC Cybersecurity Risk Management Rules (2023)
The SEC’s 2023 cybersecurity rules for registered investment advisers and investment companies require: (1) written cybersecurity policies and procedures reasonably designed to address cybersecurity risks; (2) annual review of those policies; (3) disclosure of material cybersecurity risks and incidents in Forms ADV and N-2; and (4) notification to the SEC upon discovery of a significant cybersecurity incident.
FINRA Rule 4370 — Business Continuity Plans
FINRA Rule 4370 requires all member firms to create and maintain a written Business Continuity Plan (BCP) that identifies potential risks that could disrupt the firm’s operations and establishes procedures to address those disruptions. Cybersecurity incidents — ransomware, data breaches, and system outages — are explicitly within scope as business disruption risks. FINRA examiners review BCP documentation and test whether plans are realistic and current.
FINRA Rule 3110 — Supervision
FINRA Rule 3110 requires member firms to establish and maintain a supervisory system reasonably designed to achieve compliance with applicable securities laws. SEC and FINRA have both confirmed that cybersecurity oversight is a supervisory obligation — meaning principals and supervisory personnel have a duty to understand and oversee the firm’s cybersecurity posture, and cannot delegate that responsibility entirely to IT staff or vendors.
THE 4-DAY DISCLOSURE RULE
The SEC’s most demanding cybersecurity requirement.
SEC MATERIAL INCIDENT DISCLOSURE REQUIREMENT
4 Business Days
Public companies must disclose material cybersecurity incidents to the SEC within four business days of determining the incident is material. Registered advisers have separate notification obligations. This timeline requires pre-incident preparation — a firm that discovers a breach and then begins building its response is already late.
What ‘Material’ Means in Cybersecurity
The SEC defines a material cybersecurity incident as one that a reasonable investor would consider important in making an investment decision — which in practice means any incident that affects the firm’s operations, client data, financial position, or reputation in a significant way. There is no bright-line threshold; the analysis requires judgment that must be made within four business days. This makes pre-incident planning, monitoring capability, and documented assessment procedures not just best practices but a disclosure compliance requirement.
FINRA EXAMINATION CYBERSECURITY PRIORITIES
What FINRA examiners specifically look for.
FINRA’s annual examination priorities consistently identify cybersecurity as a top-tier risk area. The following controls are routinely tested during FINRA examinations of broker-dealer cybersecurity programs:
Access controls and privileged account management — evidence of least-privilege implementation and periodic access reviews
Multi-factor authentication for all remote access and email — examiners specifically look for MFA gaps on email systems
Vendor risk management — documentation of third-party security assessments and contractual security requirements
Branch office cybersecurity — whether branch locations and remote workers meet the same security standards as headquarters
Written cybersecurity policies and procedures — current, reviewed annually, and actually implemented in practice
Incident response plan — tested, documented, and calibrated to regulatory notification timelines
Customer account takeover prevention — controls to detect and respond to unauthorized account access attempts
