300-215 Question 143
Select 3During an ongoing investigation, your organization identifies a potential zero-day exploitation targeting a critical application. As part of the incident response strategy, you are tasked to recommend actions to mitigate the risks while leveraging Cisco cybersecurity technologies. Which actions should you prioritize to address the threat effectively?
- A
Perform a risk assessment to identify the systems and data impacted by the zero-day vulnerability.
- B
Use Cisco Secure Network Analytics to monitor unusual behavior and network traffic anomalies.
- C
Deploy an immediate patch to remediate the zero-day vulnerability, regardless of testing.
- D
Leverage AI-driven SIEM solutions like Cisco Secure Cloud Analytics to predict potential vulnerabilities and prioritize response actions.
- E
Ignore the threat until an official vendor patch is released for the vulnerability.
Show answer and explanation
Correct answers: A, B, D
Explanation
A comprehensive response to a zero-day exploitation must include risk assessment to determine the impact, network monitoring to detect ongoing threats, and leveraging AI-driven SIEM tools to predict and prioritize responses. These actions ensure a proactive and effective strategy, while deploying untested patches or ignoring the threat would exacerbate risks.
- A. Correct.
Risk assessment is a critical step in identifying the scope of the impact and prioritizing response efforts. This ensures the organization understands the potential damage and can focus resources effectively.
- B. Correct.
Using tools like Cisco Secure Network Analytics to monitor network behavior is essential to detect any ongoing exploitation attempts or lateral movement associated with the zero-day vulnerability.
- C. Incorrect.
Deploying an untested patch could lead to system instability or further issues, especially for critical systems. Patches should be tested and carefully implemented to minimize risks.
- D. Correct.
AI-driven SIEM solutions can enhance predictive vulnerability management by analyzing patterns in collected data and prioritizing response actions based on potential risks. This supports proactive decision-making during zero-day exploitation scenarios.
- E. Incorrect.
Ignoring a zero-day threat is a highly negligent approach that increases the risk of exploitation and data breaches. Immediate action is necessary, even in the absence of a vendor patch.
