What is digital forensics in DFIR?
Digital forensics is the method of identifying, preserving, analyzing, and presenting digital evidence to aid investigations or legal proceedings.
What are the main activities involved in digital forensics?
The activities include structured techniques to recover and secure digital data.
Define Incident Response (IR) in DFIR.
Incident Response (IR) is the process of detecting, containing, and mitigating cybersecurity incidents to minimize damage and restore systems to normal.
What are cyber incidents?
Cyber incidents include unauthorized access, data theft, sabotage, and accidental threats, which can come from both insiders and outsiders.
Why is incident categorization important in DFIR?
Incident categorization (high, medium, low impact) helps prioritize responses based on urgency and severity, with high-impact incidents needing immediate action.
What is the preparation stage in Incident Response?
Preparation involves planning by establishing policies, educating staff, and setting up response tools to ensure readiness for incidents.
What happens during the identification stage in Incident Response?
This stage involves detecting potential incidents using tools like SIEM systems to monitor for unusual network activity or indicators of compromise (IoCs).
What is the goal of containment in Incident Response?
Containment aims to control an incident and prevent its spread, including short-term isolation or long-term solutions like network segmentation.
What is eradication in Incident Response?
Eradication focuses on removing malware or malicious activity, such as wiping infected systems and applying security patches.
What happens during the recovery phase in Incident Response?
Recovery restores systems to normal operation, verifies system and data integrity, and reintegrates any compromised accounts.
What is the purpose of the post-incident review in Incident Response?
The post-incident review assesses the incident response process, documents lessons learned, and refines future strategies to improve security posture.
What is the primary goal of business continuity in Incident Response?
Business continuity aims to minimize operational disruption during and after an incident.
Why is data protection important in Incident Response?
Data protection focuses on safeguarding critical data, intellectual property, and infrastructure from potential damage.
How does Incident Response help with cost reduction?
By quickly mitigating incidents, IR prevents the escalation of damages and financial losses.
Why is reputation management important in Incident Response?
Effective IR helps maintain customer trust and organizational reputation by handling incidents transparently.
What role does compliance play in Incident Response?
Compliance ensures adherence to legal and regulatory requirements during the response, avoiding penalties.
What is the role of evidence collection in Digital Forensics?
Evidence collection in forensics involves preserving data from affected systems to understand the incident’s origin and scope.
How does digital forensics support legal investigations?
Digital forensics provides insights into the incident’s cause, supporting legal or regulatory investigations if required.
