Recording security events in Yii can be achieved by configuring log targets, triggering key event logs, considering database storage, and avoiding recording sensitive information. The specific steps are as follows: 1. Set a dedicated log target in the configuration file, such as FileTarget or DbTarget, and specify the classification as 'security'; 2. Use Yii::info() or Yii::warning() to record the log when a critical security event (such as login failure and password reset) occurs; 3. Optionally store the logs in the database for query and analysis, and you need to create a table and configure the logTable parameters first; 4. Avoid containing sensitive data, such as passwords or tokens when recording context information, and use parameter replacement to add IP and username; 5. Ensure that the logs are rotated regularly and securely backed up to prevent malicious deletion.
Logging security events in Yii isn't too complicated, especially if you're already working within a Yii application. The framework gives you enough flexibility to capture and store important security-related actions like failed logins, unauthorized access attempts, or changes to user roles.
Here's how to go about it.
Set up a dedicated log target
Yii uses log targets to determine where logs should be stored — files, databases, emails, etc. For security events, a good starting point is to use the FileTarget or create a custom one if needed.
In your config file (like config/web.php ), add or modify the log component:
'components' => [
'log' => [
'targets' => [
[
'class' => 'yii\log\FileTarget',
'levels' => ['error', 'warning', 'info'],
'categories' => ['security'],
'logFile' => '@runtime/logs/security.log',
],
],
],
],This creates a new log target that only captures messages under the 'security' category and writes them to a separate file.
Trigger logs during key security events
Now that the logging system is ready, you need to actually call it when something happens.
For example, in a login action:
if (!$user->validatePassword($password)) {
Yii::info('Failed login attempt for user: ' . $username, 'security');
}You can also log other things like:
- Password resets
- Two-factor authentication failures
- Changes to admin settings
- Logout events (for auditing)
Use Yii::info() or Yii::warning() depending on severity. Stick with consistent categories and message formats so it's easier to parse later.
Consider storing logs in a database
While writing logs to a file works fine, sometimes you'll want to query or analyze them more easily. That's where a database target comes in handy.
Create a table first:
CREATE TABLE security_log ( id BIGINT PRIMARY KEY AUTO_INCREMENT, level INT, category VARCHAR(255), log_time TIMESTAMP DEFAULT CURRENT_TIMESTAMP, prefix TEXT, message TEXT );
Then add this target in your config:
[
'class' => 'yii\log\DbTarget',
'levels' => ['info', 'warning'],
'categories' => ['security'],
'logTable' => '{{%security_log}}',
]Now all your security logs are searchable and can be tied into dashboards or alerts.
Add context without exposing sensitive data
When logging events, it's tempting to include usernames, IPs, or even passwords — but be careful. Never log sensitive fields like passwords or tokens directly.
Instead, do something like:
Yii::info("Failed login from IP {ip} for user {username}", 'security', [
'ip' => Yii::$app->request->userIP,
'username' => $username
]);That way you get useful context without compromising privacy or compliance.
Also, make sure your logs rotate regularly and are backed up securely. If someone improves your app, they might try to erase their tracks.
Basically that's it.
