Quick Answer
The answer is auditd, the user-space component of the Linux Audit subsystem, which is the kernel feature designed to record all file access attempts. This is correct because auditd works with the kernel to capture system calls such as open, execve, and unlink, using rules configured via auditctl to log every access event as required by security policies. On the CompTIA Linux+ XK0-005 exam, this topic tests your understanding of mandatory auditing versus optional logging; a common trap is confusing auditd with syslog or rsyslog, which handle general system messages but lack the granular, rule-based system call monitoring that auditd provides. Remember that auditd is the only tool that can enforce a policy requiring auditing of *all* file access attempts, not just errors or specific daemon logs. A helpful memory tip: think of auditd as the “always-on security camera” for file operations—it watches every open and close, unlike syslog which only records what applications choose to report.
This XK0-005 practice question tests your understanding of security. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
A security policy requires auditing of all file access attempts. Which Linux kernel feature should be used?
auditd
The audit daemon can be configured to watch file accesses using audit rules.
journald
Why wrong: Journald collects logs from various sources but is not designed for file access auditing.
syslog
Why wrong: Syslog handles general system logging but does not provide granular file access auditing.
sysstat
Why wrong: Sysstat collects system performance metrics, not audit events.

Correct answer & explanation
auditd
The `auditd` service is the user-space component of the Linux Audit subsystem, which is the kernel feature designed to record file access events. It uses kernel audit rules (configured via `auditctl`) to capture system calls like `open`, `execve`, and `unlink`, enabling detailed auditing of all file access attempts as required by security policies.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
auditd
Why this is correct

journald
Why it's wrong here
Journald collects logs from various sources but is not designed for file access auditing.
syslog
Why it's wrong here
Syslog handles general system logging but does not provide granular file access auditing.
sysstat
Why it's wrong here
Sysstat collects system performance metrics, not audit events.
Common exam traps
The trap here is that candidates confuse `auditd` with general logging tools like `journald` or `syslog`, assuming any logging service can fulfill file access auditing requirements, but only the Linux Audit subsystem provides the necessary kernel-level system call interception and rule-based filtering.
Detailed technical explanation
The Linux Audit subsystem works by hooking into the kernel's system call table via the `kauditd` daemon, which generates audit records based on rules defined with `auditctl`. These records are then passed to `auditd` for logging, often to `/var/log/audit/audit.log`. A real-world scenario is compliance with PCI DSS or HIPAA, where organizations must track every read or write to sensitive files; `auditctl` can set watches on specific paths (e.g., `-w /etc/shadow -p rwxa`) to capture all access attempts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the XK0-005 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.
