- A
Alert on multiple failed login attempts
Why wrong: This indicates brute force, not exfiltration.
- B
Alert on high volume of GetObject requests from a single IP
High volume of downloads from one source is a classic exfiltration indicator.
- C
Alert on root account usage
Why wrong: Root usage is a security concern but not specific to exfiltration.
- D
Alert when a new IAM user is created
Why wrong: This detects privilege escalation, not data exfiltration.

CCSP Cloud Security Operations Practice Question
This CCSP practice question tests your understanding of cloud security operations. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An organization ingests AWS CloudTrail logs into a centralized SIEM for correlation. They want to detect an attacker who exfiltrates data by downloading large volumes from an S3 bucket. Which SIEM correlation rule would best detect this?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Alert on high volume of GetObject requests from a single IP
Option B is correct because exfiltration of data from S3 typically involves a high volume of GetObject API calls from a single source IP. A SIEM correlation rule that triggers on a threshold of GetObject requests from the same IP address directly detects this anomalous download behavior, which is a key indicator of data exfiltration.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Alert on multiple failed login attempts
Why it's wrong here
This indicates brute force, not exfiltration.
- ✓
Alert on high volume of GetObject requests from a single IP
Why this is correct
High volume of downloads from one source is a classic exfiltration indicator.

Alert when a new IAM user is created
Why it's wrong here
This detects privilege escalation, not data exfiltration.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between detection of the exfiltration action itself (high volume of GetObject requests) versus precursor or unrelated events (failed logins, root usage, IAM creation), leading candidates to choose a rule that detects a different phase of the attack chain.
Detailed technical explanation
How to think about this question
CloudTrail logs each S3 API call as a JSON record containing the eventName (e.g., GetObject), sourceIPAddress, and requestParameters. A SIEM correlation rule can aggregate these events by source IP over a sliding time window (e.g., 1000 GetObject requests in 5 minutes) to trigger an alert. In real-world scenarios, attackers often use compromised IAM credentials or temporary tokens to download data, making the source IP a reliable indicator when combined with volume thresholds.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
