Spring Security Eventlog Plugin

This plugin creates a simple log of spring security events. Each time a user logs in or logs out, a log entry will created, storing the remote address, session id, user name, event name, switched user name, and the time at which the event occurred.

Events are logged to a table named SPRING_SECURITY_EVENT, mapped to a domain object ca.redtoad.eventlog.SpringSecurityEvent.

Each event has the following fields:

• username - the username entered
• sessionId - the user's session
• eventName - the name of the event
• remoteAddress - the user's IP address
• switchedUsername - username that is being switched to
• dateCreated - the event's timestamp

Some of the event names that are captured:

• AuthenticationFailureBadCredentialsEvent - a bad username or password
• AuthenticationSuccessEvent - a successful login
• InteractiveAuthenticationSuccessEvent - a successful login where the user entered his/her username and password
• AuthenticationSwitchUserEvent - user having ROLE_SWITCH_USER has assumed the identity of a (likely different) user
• Logout - a user logged out interactively

Customizing

You can specify your own logger if you would like to override how events get logged. Create a subclass of SpringSecurityEventLogger and add your custom behavior to logAuthenticationEvent. For example:

package mypackage

import ca.redtoad.eventlog.SpringSecurityEventLogger
import org.springframework.security.core.Authentication

class CustomEventLogger extends SpringSecurityEventLogger {
    void logAuthenticationEvent(String eventName, Authentication authentication, String remoteAddress) {
        println "$eventName! $authentication from $remoteAddress"
    }
}

In your Config.groovy, tell grails to your own event logger class:

grails.plugins.springsecurity.eventlog.eventLogger = mypackage.CustomEventLogger
