Digital Forensics and Incident ResponseDigital Forensics and Incident Response (DFIR) is a field within cybersecurity that focuses on the identification, investigation, and remediation of cyberattacks.
A DFIR capability is becoming an increasingly important component for organisations seeking to maintain business continuity in the digital era. Crucially, DFIR processes contain incidents as quickly as possible and prevent a cyber attack becoming a cyber crisis.

Digital forensics and incident response (DFIR) is a specialized field focused on identifying, remediating, and investigating cyber security incidents. Digital forensics includes collecting, preserving, and analyzing forensic evidence to paint a full, detailed picture of events.
Digital Forensics and Incident Response (DFIR) is a specialized cybersecurity functional sub-field traditionally associated with computer emergency response teams (CERT) or computer security incident response teams (CSIRT) called in to respond to a cybercrime or similar emergency.

Is Digital Forensics a Good Career? Yes, digital forensics is a good career for many professionals. According to the Bureau of Labor Statistics, demand for forensic scientists and information security analysts is expected to be very high.
Computer forensics can be a stressful field, as you often need to find information quickly for a criminal investigation and criminals can be highly skilled at technology.
Is computer forensics a good degree? Yes, a bachelor's degree in computer forensics equips graduates with invaluable technical and career skills. This degree qualifies graduates for careers as information security analysts and computer forensics technicians.
DFIR Processes One of the first steps to a forensic investigation is collecting the RAM (memory) from the computer using a tool like DumpIT. Then you can extract additional evidence such as Event Logs, Registry, $MFT, etc.
There are four phases involved in the initial handling of digital evidence: identification, collection, acquisition, and preservation ( ISO/IEC 27037 ; see Cybercrime Module 4 on Introduction to Digital Forensics).
IR is focused on the containment of a threat or attack. Forensics involves a thorough examination of the data in order to gain a complete understanding of the breach in order to remediate the attack and prevent a recurrence.
