NEW QUESTION # 209
The SOC team has confirmed a potential indicator of compromise on an endpoint. The team has narrowed the executable file's type to a new trojan family. According to the NIST Computer Security Incident Handling Guide, what is the next step in handling this event?
- A. Collect public information on the malware behavior.
- B. Isolate the infected endpoint from the network.
- C. Prioritize incident handling based on the impact.
- D. Perform forensics analysis on the infected endpoint.
Answer: A
Explanation:
According to the NIST Computer Security Incident Handling Guide, the next step in handling an event after confirming a potential indicator of compromise on an endpoint is to collect public information on the malware behavior. This step involves searching for information from various sources, such as antivirus vendors, security blogs, threat intelligence feeds, and online forums, to learn more about the characteristics, capabilities, and impact of the malware. This information can help the SOC team to identify the type, severity, and scope of the incident, as well as to determine the appropriate response actions and mitigation strategies.
Isolating the infected endpoint, performing forensics analysis, and prioritizing incident handling are subsequent steps that follow after collecting public information on the malware behavior. References:

- A. installation
- B. reconnaissance
- C. action on objectives
- D. exploitation
Answer: D
Explanation:
This event category is exploitation because the HTTP requests contain PHP code that attempts to execute commands on the web server and create a backdoor. Exploitation is the phase of the attack where the threat actor gains access to the target system and executes malicious code. References: https://learningnetworkstore.

An analyst discovers that a legitimate security alert has been dismissed. Which signature caused this impact on network traffic?
- A. true positive
- B. false positive
- C. false negative
- D. true negative
Answer: C
Explanation:
A false negative occurs when an intrusion detection system (IDS) fails to detect and report actual malicious activity. This means that a legitimate security alert has been dismissed or overlooked, allowing potentially harmful traffic to pass through the network undetected. The impact of false negatives can be significant as they represent missed opportunities to stop or mitigate security threats1.
