300-215 Question 142
Select 3A cybersecurity team has detected unusual traffic patterns in their network. Upon investigation, they suspect that a zero-day vulnerability is being exploited. Using Cisco's cybersecurity technologies, what actions should the team take to mitigate the threat and predict future vulnerabilities?
- A
Conduct a risk assessment to evaluate the impact and likelihood of the zero-day exploitation.
- B
Deploy an AI-based predictive vulnerability management solution to analyze SIEM data and identify potential future threats.
- C
Immediately block all external traffic through the firewall without further investigation.
- D
Leverage Cisco SecureX to correlate threat intelligence from multiple sources and automate responses.
- E
Ignore the incident until a patch is released for the suspected vulnerability.
Show answer and explanation
Correct answers: A, B, D
Explanation
Responding to a zero-day exploitation requires a comprehensive approach. Conducting a risk assessment helps the team understand the threat's impact and prioritize actions. AI-based predictive vulnerability management tools analyze SIEM data to predict and mitigate future risks. Cisco SecureX enhances response capabilities by correlating threat intelligence and automating workflows. Immediate blocking of all traffic or ignoring the incident are not effective or responsible responses to the threat.
- A. Correct.
Conducting a risk assessment is critical to understanding the potential impact and likelihood of the zero-day exploitation, enabling the team to prioritize response efforts.
- B. Correct.
Using an AI-based predictive vulnerability management solution allows the team to process SIEM data, predict potential vulnerabilities, and proactively mitigate risks.
- C. Incorrect.
Blocking all external traffic without further investigation is an overly aggressive response that could disrupt legitimate business operations and fail to address the root cause of the threat.
- D. Correct.
Cisco SecureX provides a centralized platform to correlate threat intelligence from multiple sources, automate responses, and improve incident response efficiency.
- E. Incorrect.
Ignoring the incident until a patch is released neglects the immediate threat and leaves the organization exposed to further exploitation.
