The Driving Force
IT professionals are driven by the desire to increase the overall productivity of the business. If information is being generated and transferred to the key players then, the IT department is very happy. They are similar to banks in an economy that are happy when commerce is taking place among the right players.
However, if too many rouge applications, enters the business, transferring information to the wrong players, and the overall productivity of the business is at threat, then it is time to lock down the gates. This creates a negative image but, someone has to do it. It is similar to banks locking down credit, because credit is being spent by the consumer mostly on consumption goods and not on productive goods.
