}Refer to the exhibit. A security analyst reviews this CloudTrail log entry. What is the most immediate concern?
⚠ Common exam trap
ISC2 often tests the distinction between an authorization failure (IAM policy deny) and a successful but dangerous action; the trap here is that candidates see the user name and assume a permission error, but the log shows the action succeeded, making the unrestricted SSH rule the real risk.
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
✓
A security group rule was added that allows unrestricted SSH access.
The CloudTrail log entry shows an AuthorizeSecurityGroupIngress API call that added a rule allowing SSH (port 22) from source 0.0.0.0/0, which grants unrestricted internet access. This is a critical security misconfiguration that exposes the EC2 instance to potential brute-force attacks or unauthorized access, making it the most immediate concern.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A user named john.doe is not authorized to modify security groups.
Why it's wrong here
The log shows the action succeeded, implying authorized.
- ✗
An EC2 instance was launched without approval.
Why it's wrong here
The event is about security group rule, not instance launch.
- ✓
A security group rule was added that allows unrestricted SSH access.
Why this is correct
SSH from 0.0.0.0/0 is a major security exposure.
- ✗
The user john.doe failed to authenticate.
Why it's wrong here
The event indicates a successful action.
