Introduction:
1. Scenario:
Question: You suspect a security breach on a Windows server.
What specific event IDs or log entries would you examine in the Security log to
identify potential unauthorized access?
Answer: I would focus on event IDs such as 4624 (Successful
Logon), 4625 (Failed Logon), and 4672 (Special privileges assigned to a new
logon). These entries can provide insights into user authentication and
potential security threats.
2. Scenario:
Question: A user reports sudden system performance issues.
How would you use Windows Event Logs to investigate this problem?
Answer: I would check the System log for critical errors
(event ID 41, Kernel-Power) that might indicate hardware issues. Additionally,
I would review application and service-related logs for event IDs that could
point to performance bottlenecks.
3. Scenario:
Question: Your organization needs to track changes to Group
Policy settings. Which event IDs in the Security log would you examine?
Answer: I would look for event ID 4719 (System Audit Policy
Change) in the Security log to identify any modifications to Group Policy
settings.
4. Scenario:
Question: A critical service unexpectedly terminates. How
would you use Windows Event Logs to identify the cause?
Answer: I would check the System log for event ID 7034
(Service Control Manager) to identify the service that terminated unexpectedly.
Further investigation involves reviewing associated events and logs for
potential causes.
5. Scenario:
Question: You suspect malware on a workstation. How would
you use Windows Event Logs to find indications of malicious activity?
Answer: I would examine the Security log for event IDs
related to account logon (4624, 4625) and process execution (4688). Unusual
patterns or suspicious processes could indicate malware.
6. Scenario:
Question: A user complains about files being accessed
without authorization. Which event IDs in the Security log would you examine?
Answer: I would check event ID 4663 (An attempt was made to
access an object) in the Security log to identify unauthorized access to files
or resources.
7. Scenario:
Question: You need to investigate a user's account for
potential security incidents. What event IDs in the Security log would you
focus on?
Answer: I would focus on event IDs 4720 (A user account was
created), 4724 (An attempt was made to reset an account's password), and 4726
(A user account was deleted) to track account-related activities.
8. Scenario:
Question: An application is misbehaving, and you suspect a
problem with its execution. Which event IDs in the Application log would you
examine?
Answer: I would look for event ID 1000 (Application Error)
in the Application log to identify issues with the application's execution.
9. Scenario:
Question: You want to monitor network-related activities on
a server. Which event IDs in the Security log would you focus on?
Answer: I would examine event IDs such as 5156 (Windows
Filtering Platform) to track network-related activities and identify any
unexpected connections or traffic.
10. Scenario:
Question: A user accidentally deletes important files. How
would you use Windows Event Logs to track this incident?
Answer: I would check the Security log for event IDs 4660
(An object was deleted) and 4663 (An attempt was made to access an object) to
identify the deletion event and associated details.
11. Scenario:
Question: You need to investigate when a specific user last
logged into a workstation. Which event IDs in the Security log would you
examine?
Answer: I would focus on event IDs 4624 (Successful Logon)
and 4634 (An account was logged off) in the Security log to track the user's login
and logout events.
12. Scenario:
Question: An administrator mistakenly changes a critical
Group Policy setting. How would you use Windows Event Logs to identify and
revert this change?
Answer: I would review event ID 4719 (System Audit Policy
Change) in the Security log to identify the modification to Group Policy
settings. Once identified, corrective actions can be taken.
13. Scenario:
Question: You suspect that a specific process is causing
system instability. How would you use Windows Event Logs to investigate?
Answer: I would review the Application log for event ID 1000
(Application Error) and the System log for event ID 7031 (Service Control
Manager) to identify issues related to the problematic process.
14. Scenario:
Question: An external connection to a server is suspected.
How would you use Windows Event Logs to verify and trace this connection?
Answer: I would examine event IDs such as 5156 (Windows
Filtering Platform) in the Security log to track network-related activities,
focusing on external connections or unexpected traffic.
15. Scenario:
Question: A user complains of repeated account lockouts. How
would you use Windows Event Logs to identify the cause?
Answer: I would check the Security log for event IDs 4625
(Failed Logon) to identify the source of the account lockouts, and then
investigate further for potential issues.
16. Scenario:
Question: An unauthorized user gains access to a workstation.
How would you use Windows Event Logs to trace their activities?
Answer: I would review event IDs 4624 (Successful Logon) and
4625 (Failed Logon) in the Security log to identify the unauthorized access and
trace the user's activities.
17. Scenario:
Question: A critical service experiences delays in startup.
How would you use Windows Event Logs to identify the cause?
Answer: I would examine the System log for event IDs 7000,
7009, and 7011 (Service Control Manager) to identify issues related to the
delayed startup of the service.
18. Scenario:
Question: You suspect that a user is trying to access files
they shouldn't. How would you use Windows Event Logs to investigate?
Answer: I would check event IDs 4656 (A handle to an object
was requested), 4660 (An object was deleted), and 4663 (An attempt was made to
access an object) in the Security log to identify unauthorized file access.
