# 4.1.8 Ensure login and logout events are collected (Scored)

## Profile Applicability

- Level 2 - Server
- Level 2 - Workstation

## Description

Monitor login and logout events. The parameters below track changes to files associated with login/logout events. The file `/var/log/faillog` tracks failed events from login. The file `/var/log/lastlog` maintain records of the last time a user successfully logged in. The file `/var/log/tallylog` maintains records of failures via the `pam_tally2` module.

## Rationale

Monitoring login/logout events could provide a system administrator with information associated with brute force attacks against user logins.

## Audit Procedure

Run the following commands:

```bash
grep logins /etc/audit/audit.rules
auditctl -l | grep logins
```

## Expected Result

Verify output of both includes:

```
-w /var/log/faillog -p wa -k logins
-w /var/log/lastlog -p wa -k logins
-w /var/log/tallylog -p wa -k logins
```

## Remediation

Add the following lines to the `/etc/audit/audit.rules` file:

```bash
-w /var/log/faillog -p wa -k logins
-w /var/log/lastlog -p wa -k logins
-w /var/log/tallylog -p wa -k logins
```

**Notes:** Reloading the auditd config to set active settings may require a system reboot.

## Default Value

Not configured by default.
