What is the reporting timeframe for a CAT-3 incident categorized under US-CERT?

• A. 2 hours
• B. Daily
• C. Monthly
• D. Annually

Answer: (B)

The reporting timeframe for a CAT-3 incident categorized under US-CERT is daily, which means that incidents classified under this tier, which may be significant but not classified as the highest severity, must be reported on a daily basis. This frequent reporting is critical as it ensures that relevant stakeholders are timely informed about significant cybersecurity incidents, enhancing overall situational awareness and response effectiveness. Daily reporting allows for more immediate corrective actions or mitigation steps to be taken in response to vulnerabilities or threats that may be evolving. By disseminating information consistently, organizations can adjust their security posture and implement protective measures against potential risks before they escalate into more severe incidents. Regular updates contribute to a comprehensive understanding of the organization's security landscape and enable better preparedness for future threats. The other timeframes, such as monthly or annually, would not provide the necessary immediacy required to effectively manage CAT-3 incidents, as the nature of cybersecurity threats is often dynamic and requires quick responses. The option of 2 hours is more appropriate for the highest severity incidents, which necessitate even more urgent attention and reporting. Thus, the daily reporting requirement aligns well with the operational needs for managing CAT-3 incidents efficiently.
