The U.S. Securities and Exchange Commission adopted new cybersecurity regulations on July 26, 2023, and the rules became effective 30 days after their publication in the Federal Register. Anybody who has done an annual report since December 15, 2023, must already be working under these regulations. That means that all public companies have to make a mandatory report about their cybersecurity status, their vulnerabilities, and their risks in their annual reports.
What the new rule means for companies and CISOs
What this means for CISOs breaks down into two parts. The new SEC regulations on reporting security attacks have several significant ramifications for public companies. These apply to the company itself and then directly to the person in the CISO position. Mandatory disclosures require organizations to disclose cybersecurity incidents within four business days and determine their materiality. This responsibility was vague in the past, and many interpreted it as meaning that only in the case of a material incident did you need to disclose.
Cybersecurity now applies at a higher level
New requirements regarding materiality assessment mean that as companies assess and determine the materiality of a cybersecurity incident, they can no longer just consider the actual impact, but they must consider both the actual and expected impact. Doing so can be very challenging due to the qualitative nature of such assessments. Some of the impact is based on how people see an organization. When it comes to reputation, how do you quantify the cost of the impact on the company? Another requirement regards detailed annual reporting on cybersecurity risk that needs to cover management, strategy, and governance, and it now includes the Board of Directors’ oversight and management's roles in those areas. Before, cybersecurity reporting responsibility was typically held at the CISO level. Now cybersecurity has been pushed higher, making it a focus and responsibility of the board of directors and senior leadership.
The implications of the new regulations for CISOs
CISOs now have significantly increased accountability. They are now accountable for timely reporting of material cybersecurity breaches within a strict four-day window after an incident is deemed material. Well, that means now, as a CISO, you are responsible for the materiality decision VERY quickly. That impacts not just the CISO, but every person who has stock in the company. Suddenly a swath of leadership is eligible to be fined. The flip side of that coin is the risk of premature disclosure. The requirements to disclose incidents quickly can lead to reporting vulnerabilities before their significance is fully understood. It may be too soon to know how they could potentially affect the company's public image and stock price. Four days to estimate impact may not be enough time. Anybody who's been involved in a large incident knows that sometimes it will be six months before you really know the impact.
Reporting timeline considerations for CISOs
Some of these incidents go on for weeks and months before all the impact has happened or before they're contained. I would not want to be the person who goes in and prematurely discloses a security incident due to the tight reporting window and negatively affect the company's stock price. I think about the ramifications personally for my CISO performance metrics, as well as the company's performance metrics. This puts the CISO in the unenviable position of affecting many people in an organization. For example, consider someone relying on an annual bonus based on performance metrics, or someone nearing retirement and getting ready to cash out on investments tied to the stock price. The CISO is potentially now impacting everybody who's related to the company.
A CISO balancing act
So CISOs are now walking a really fine line. On the one side, they've got to protect the company, its reputation, and the company's valuation in the market. CISOs are not just protecting the company, but they are also protecting the company’s investors. These regulations from the SEC require the CISO to maintain that balance. The SEC has put these rules in place in good faith to help companies, to protect investors, and to provide some guidance for dealing with inevitable cybersecurity breaches, as they happen.
