NSE7 Troubleshooting and Diagnostics Practice Question
A FortiGate administrator is investigating a security incident and needs to identify which user initiated a specific outbound connection to a malicious IP address. The company uses FSSO for authentication. Which THREE pieces of information from FortiAnalyzer logs would be MOST useful? (Choose three.)
⚠ Common exam trap
The trap here is that candidates often select 'Destination IP address' thinking it helps identify the user, but it only identifies the target of the attack, not the initiator, and fails to leverage the FSSO authentication mapping required for user attribution.
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
✓
Username from the FortiGate authentication log
FSSO (Fortinet Single Sign-On) maps network sessions to Active Directory usernames via the FortiGate authentication log. When investigating which user initiated an outbound connection to a malicious IP, the username from this log directly ties the session to a specific identity, enabling attribution beyond just IP addresses.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Username from the FortiGate authentication log
Why this is correct
Links the session to the authenticated user.
- ✗
Destination IP address
Why it's wrong here
Already known (malicious IP); not needed to identify the user.
- ✗
Event type (e.g., traffic, event, attack)
Why it's wrong here
Event type is not directly useful for identifying the user.
- ✓
Source IP address of the session
Why this is correct
Identifies the device that initiated the connection.
- ✓
Timestamp of the session
Why this is correct
Helps correlate with other logs and timeline.
