The spring security plugin is the way to go. http://grails.org/plugin/spring-security-core

I would recommend using the annotation approach. There is a section on using annotations in the blog post http://blog.springsource.com/2010/08/11/simplified-spring-security-with-grails/

I would recommend reading the above blog post in its entirety

E.g. Controller action would be secured like....

//all users
@Secured(['IS_AUTHENTICATED_REMEMBERED'])
def firstAction = { ... }

//only admin
@Secured(['ROLE_ADMIN'])
def secondAction = { ... }

The plugin also offers a "remember me" option if you dont want to force your users to always login

I suggest to use the controllers interceptors http://grails.org/doc/latest/guide/6.%20The%20Web%20Layer.html#6.1 Controllers

or install the Spring Security Core plugin http://www.grails.org/plugin/spring-security-core.
