Understanding hackers: The insider threat

“Oh, we’re good, we do external penetration testing.”

Have you heard people say this (or perhaps even said it yourself)?

Companies often think of attackers as something that comes from the outside, yet overlook the far more dangerous threat: attackers from within. Have you adequately considered how the people you already know and trust might actually be a threat vector?

Furthermore, even companies who are considering the insider threat often mistake it as a single attacker type, when it’s actually a collection of attacker types. Some act opportunistically, while others simply make a mistake. Some were once trustworthy but then become disgruntled, while others act maliciously from the outset.
