Correct answer & explanation
✓
SEC proposed rules
The SEC's proposed rules (now final) require publicly traded companies to report material cybersecurity incidents on Form 8-K within 4 business days of determining materiality. This is a specific U.S. securities regulation, not a privacy or payment card standard, and it directly mandates the 4-business-day notification window for material incidents.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between regulatory notification timelines (e.g., GDPR's 72 hours vs. SEC's 4 business days) and the specific scope of each regulation, leading candidates to confuse privacy breach notification with material incident reporting.
Detailed technical explanation
How to think about this question
The SEC's incident reporting rule (Item 1.05 of Form 8-K) triggers a 4-business-day clock from the date the registrant determines the incident is material, not from the date of discovery. This materiality determination involves a qualitative and quantitative assessment of the incident's impact on financial condition, operations, or reputation, and the 4-business-day count excludes weekends and federal holidays. The rule also requires a detailed description of the incident's nature, scope, and ongoing impact, with a potential delay for law enforcement if disclosure would impede an investigation.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CISM exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
