This week Cnet interviewed Phil Lapsley, the author of Exploding the Phone, a book about the early history of phone phreaking.

I got the letter this week. The one from (ISC)². If the first word is “congratulations,” it means you passed. But if the first two words are “thank you,” you didn’t. If you want the letter that says “congratulations” in your future, it helps to know how to study for CISSP. Here’s how I studied for mine. Hopefully it will help you. It’s a long road. But it’s doable.
