"It's a lonely journey, but man, that ending is worth it!!" – Luke Ahmed Today is Day 30 of Yihenew’s CISSP study plan, focusing on penetration testing — a critical concept that blends technical skill with management-level understanding of risk validation. Key Areas Covered: Purpose of Pen Testing — to simulate real-world attacks and test how effective existing controls are, both technically and procedurally. Pen Test vs. Vulnerability Scan — vulnerability scans identify p
