Another cool cable option is a retractable cable alarm unit. I bought one similar to this ebay one:

that will make noise if disturbed, which adds another layer of security to your helmet and gear on the bike. I secure the helmet and jacket to the passenger grab rail when I need to leave them there. You can easily find that type of cable alarm for less than $10.
