It's an attached property, so you need to either call the attached property accessor, or call GetValue and pass in the dependency property.

Try something like this:
public static class SecurityBehavior
    private static readonly char[] TagSeparators = { '|' };
    public static readonly DependencyProperty SecurityTagsProperty =
        typeof(string), typeof(SecurityBehavior),
        new PropertyMetadata("", OnSecurityChanged));
    public static string GetSecurityTags(DependencyObject obj)
        return (string)obj.GetValue(SecurityTagsProperty);

    public static void SetSecurityTags(DependencyObject obj, string value)
        obj.SetValue(SecurityTagsProperty, value);

    public static readonly DependencyProperty AllowEnableProperty =
        new PropertyMetadata(false, OnSecurityChanged));

    public static bool GetAllowEnable(DependencyObject obj)
        return (bool)obj.GetValue(AllowEnableProperty);

    public static void SetAllowEnable(DependencyObject obj, bool value)
        obj.SetValue(AllowEnableProperty, value);
    private static void OnSecurityChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
        bool canEnable = GetAllowEnable(sender);
        if (canEnable)
            string[] tags = GetSecurityTags(sender).Split(TagSeparators, StringSplitOptions.RemoveEmptyEntries);
            foreach (string tag in tags)
                canEnable &= SecurityService.HasRights(tag);
        var element = (UIElement)sender;
        element.IsEnabled = canEnable;
