Best Practices

I've read and viewed all the tutorials on workflows. There is one particular detail that I did not see covered. In my workflow I'm going to have a software approval process. A user will request and then a decision board will approve and then it will move on to risk assessment and so on. Each ticket when closed kicks off the next one. But what if there is a denial along the way? For example, if the board denies the request. Is there an option to cancel the workflow and close that ticket without generating any subsequent tickets?

Thanks for the help.
