Identify which of the following statements about the defense-in-depth security model are true.

A defense-in-depth strategy only focuses on technical tools like firewalls and ignores physical security or human training.

The strategy aims to create a single, unbreakable wall that is impossible for any attacker to ever get through.

Using multiple security layers helps to slow down attackers and gives the security team more time to detect and respond to a threat.

The main goal of using multiple layers is to make sure that if one security measure fails, others are still there to protect the system.
