Security teams should not operate under the assumption that a breach will happen, but when. The fresh twist on penetration testing puts an attacker (good guy/gal) on your systems running under the context of an authorized user. The goal is to simulate a compromised system or a rogue trusted insider. The goals of the test should be focused on the business risk and how insecurities, vulnerabilities, and misconfigurations can impact the data and processes vital to the organization. Goals are business focus, not 'domain admin ' focused.
