My client had been experiencing errors and fraud in health plan and pension paperwork. We narrowed the problem to poor corporate ID badge management, database servers that were left unattended and terminated employees who still had network access.
But I remembered some wisdom from Chip Gliedman at think-tank Forrester: If I build a 10-foot wall around my house for a thousand dollars, I may feel secure. But what happens when a fence salesman proposes to put three feet of barbed wire fence on top of my concrete wall for another grand? I have to decide if the extra height makes me more secure, and if so, whether it is worth all that money.
