In the last chapter, you learned about the three pillars that sustained your security posture, and two of them (detection and response) are directly correlated with the Incident Response (IR) process. To enhance the foundation of your security posture, you need to have a solid incident response process. This process will dictate how to handle security incidents and rapidly respond to them.
