DFIR stands for Digital Forensics and Incident Response, a specialized field within cybersecurity that deals with identifying, investigating, and remediating cyberattacks and security incidents. It combines the skills of both digital forensics and incident response to provide a comprehensive approach to cybersecurity threats.

Digital forensics focuses on the preservation, collection, analysis, and presentation of digital evidence from a cybercrime or security incident. This involves tasks like:

• Securing the scene: Ensuring the integrity of digital evidence by taking steps like isolating affected devices and networks.
• Acquiring evidence: Creating forensic copies of data from devices like computers, smartphones, and servers.
• Examining evidence: Analyzing the data to identify malicious activity, reconstruct the timeline of events, and gather evidence for prosecution.
• Reporting findings: Presenting the results of the investigation in a clear and concise manner for legal and technical audiences.

Incident response, on the other hand, focuses on the immediate actions taken to contain, eradicate, and recover from a security incident. This involves tasks like:

• Identifying the incident: Recognizing and understanding the nature of the attack.
• Containing the threat: Stopping the attack from spreading and minimizing damage.
• Eradicating the threat: Removing the malware or other malicious software from affected systems.
• Recovering from the incident: Restoring affected systems and data to their pre-incident state.
• Reviewing and improving: Analyzing the incident to identify vulnerabilities and improve security defenses.
