You have several options. For a small installation, use something like
the following:
public class UserRealm extends AuthorizingRealm {
        public UserRealm() {
                super(new MemoryConstrainedCacheManager());

For an enterprise installation, consider using an EhCache. Shiro has
pretty reasonable documentation on caching strategies, see
http://shiro.apache.org/caching.html and
http://shiro.apache.org/static/current/apidocs/org/apache/shiro/realm/AuthorizingRealm.html
