DFIR life cycle
Before delving into this forensic use case, it is crucial to grasp the concepts of forensics and digital forensics, along with an understanding of Digital Forensic and Incident Response (DFIR) tools. Digital forensics involves the systematic identification, analysis, preservation, and secure storage of digital evidence essential for legal investigations. The DFIR life cycle is an indispensable component of any digital organization. The subsequent figure illustrates the NIST incident response life cycle:

Let’s explain the steps in this life cycle as follows:
- Preparation: This phase involves the organization preparing its incident response plan, conducting risk analysis, identifying vulnerabilities, and documenting whether to resolve, expedite, or accept each identified issue.
- Detection and analysis: In this context, EDR assumes a paramount role, outstripping conventional...
