What is digital forensics and incident response (DFIR)?

Digital Forensics and Incident Response (DFIR) refers to the combined set of cybersecurity operations used to detect, investigate, and respond to cyber threats. Digital forensics collects data to understand the incident while incident response involves mitigating and containing the effects of a security breach. DFIR helps organizations better understand security incidents, improves recovery time, and strengthens security posture. However, challenges include managing massive volumes of data, preserving evidence, and staffing issues. Selecting an effective DFIR tool should consider proximity, service type, forensic capabilities, and integration with existing security tools.
