300-215 Question 215
Select 4While conducting a forensic analysis, you are reviewing a Cisco ThreatGrid report for a suspicious file discovered on a compromised endpoint. Which components of the ThreatGrid report should you evaluate to determine if the file exhibits malicious behavior?
- A
Behavior indicators and their associated severity levels
- B
Network communication patterns and connections made by the file
- C
The file's hash and its reputation score
- D
The file's access permissions on the endpoint
- E
Dynamic analysis results showing runtime behavior of the file
- F
The timestamp of the last antivirus scan on the endpoint
Show answer and explanation
Correct answers: A, B, C, E
Explanation
When evaluating a ThreatGrid report, key components to review include behavior indicators, network communication patterns, file reputation, and dynamic analysis results. These elements provide comprehensive insights into the file's behavior and potential malicious activity. Other options, such as access permissions or antivirus scan timestamps, do not directly pertain to ThreatGrid's analysis capabilities, making them irrelevant in this context.
- A. Correct.
ThreatGrid's behavior indicators and severity levels provide insights into potentially malicious actions performed by the file, such as system modifications or exploitation techniques.
- B. Correct.
Network communication patterns reveal if the file is attempting to establish connections to suspicious domains or IPs, which is critical for determining malicious intent.
- C. Correct.
The file's hash and reputation score help identify if the file is already known to ThreatGrid or other security databases as malicious or benign.
- D. Incorrect.
The file's access permissions on the endpoint are not directly evaluated in ThreatGrid reports; this information is associated more with system-level forensics.
- E. Correct.
Dynamic analysis in ThreatGrid simulates the file's runtime behavior in a sandbox environment to identify malicious actions, making it an essential component to review.
- F. Incorrect.
The timestamp of the last antivirus scan is unrelated to ThreatGrid's analysis and does not contribute to determining the malicious behavior of the file.
