Defensive security is the process of defending and securing devices and systems.
Before you can defend a system, you need to understand what defenders are responsible for. Defensive security focuses on detecting and investigating attacks, and responding before damage occurs.
Unlike offensive security, you do not attack systems, instead, you monitor and protect them.
