XK0-006 Security Practice Question
A system is running SELinux in enforcing mode. A custom application needs to write to /var/log/app.log. The log file shows the correct context, but access is denied. What is the most likely cause?
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
✓
The SELinux boolean for the application is disabled.
SELinux policy may not allow the application's domain to write to that file; audit2allow can generate a policy. But the question implies a boolean or context issue. However, typical cause is missing policy rule. But among options, 'The application is running in an unconfined domain' is plausible but not best. Actually, the most common cause is that the file context is wrong. But given the file has correct context, the issue is likely a boolean or policy. However, the best answer is 'A transition to the wrong domain'? I'll go with 'The SELinux boolean for the application is disabled'.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The file context is incorrect.
Why it's wrong here
Stem says context is correct.
- ✗
The application is running in an unconfined domain.
Why it's wrong here
Unconfined domains have few restrictions; would not cause denial.
- ✓
The SELinux boolean for the application is disabled.
Why this is correct
Many applications require a boolean to be enabled.
- ✗
SELinux is in permissive mode.
Why it's wrong here
Permissive mode logs but allows; not enforcing.
