While I may be in the minority, IT security is never going to be "sexy," and rarely going to merit a C-level or board level position.
The security folks in the room will beat me up on this, but security spending is like life insurance. Everyone knows they need it, but everyone hates going through the exercise of buying it and wants to get it over with quickly. If you’re tasked with pitching IT security at your company, determine some different levels of security (aka insurance) and their associated costs, determine what your company is comfortable spending, and outline the risks associated with each spend level. Then write the check and be done with it.
You’ll look like Captain Doomsday or completely out of touch with the business as a whole if you spend months touting security while your peers are trying to get products out the door.
