Something we preach very strongly in our training is the importance of an understanding of the underlying technology / application / issues, and being able to dig into the core of an issue, not just try a trick or two and move on. Sadly, most people don’t see it this way. It’s also somewhere between sad and frustrating for me that there seems to be an over-abundance of so-called “experts” in our field. While this isn’t an issue for those who have a deep understanding, the fact of the matter is that for many of our customers, their key competence is their respective industry, and not information security.
