The answer is to review the IAM policies attached to the user to determine if the action was authorized. This is correct because an AccessDenied error in CloudTrail explicitly indicates that the requested operation—in this case, listing an S3 bucket—was denied by AWS’s permission system, meaning the IAM user lacks the necessary resource- or action-level permissions. On the Computer Hacking Forensic Investigator CHFI exam, this scenario tests your ability to distinguish between a legitimate policy misconfiguration and a potential unauthorized access attempt; a common trap is to immediately assume malicious activity, but the forensic next step is always to verify the attached policies first. Remember that AccessDenied is a permission failure, not a security alert—so always check the policy before escalating. A useful memory tip: “Denied? Check the policy side.”
CHFI Application, Email and Cloud Forensics Practice Question
This CHFI practice question tests your understanding of application, email and cloud forensics. 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.
During a cloud forensics investigation of an AWS environment, an analyst extracts CloudTrail logs and notices many events with the error code 'AccessDenied' for a specific IAM user attempting to list an S3 bucket. Which of the following is the most appropriate next step?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Review the IAM policies attached to the user to determine if the action was authorized
AccessDenied indicates the user lacks permissions; check IAM policies to see if the user should have access or if it's an unauthorized attempt.
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.
✓
Review the IAM policies attached to the user to determine if the action was authorized
Why this is correct
Logs show AccessDenied, so the user is blocked, but reviewing policies helps understand intent and whether policies are misconfigured.
Related concept
Read the scenario before looking for a memorised answer.
✗
Immediately disable the IAM user account
Why it's wrong here
Disabling may be premature; first investigate the context and policies.
✗
Escalate the issue to law enforcement
Why it's wrong here
AccessDenied events are common and not necessarily a crime; investigation first.
✗
Check the S3 bucket's access logs for the same IP address
Why it's wrong here
CloudTrail already shows the event; S3 server logs would be redundant.

TExam Day Tips
→Underline the problem statement mentally.
→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 practitioner preparing for the CHFI exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
