Forensics Interview
Basic digital forensics Q&A
Foundational questions covering evidence, preservation, and core concepts.
What is Digital Forensics?
answerDigital Forensics is the process of collecting, preserving, analyzing, and presenting digital evidence during investigations.
What is Digital Evidence?
answerInformation stored or transmitted in digital form used during an investigation. Examples: computer files, emails, system logs, mobile data, cloud records.
Phases of a forensic investigation?
answer- Identification
- Preservation
- Collection
- Examination
- Analysis
- Reporting
Why is evidence preservation important?
answerMaintains integrity and prevents data modification during investigations.
What is Chain of Custody?
answerDocuments how evidence is collected, handled, transferred, and stored throughout an investigation.
What is forensic imaging?
answerCreating an exact copy of storage media for analysis while preserving original evidence.
What is metadata?
answerData about data. Examples: creation date, modification date, file owner, access information.
Volatile vs non-volatile data?
answerVolatile: temporary memory data that disappears after shutdown. Non-volatile: stored on hard drives, SSDs, USB drives.
Why are logs important?
answerLogs help identify activities, events, and security incidents during investigations.
Intermediate forensics Q&A
Deeper questions on memory analysis, file carving, hashing, and incident response.
What is memory analysis?
answerExamining system memory to identify processes, network connections, and evidence related to incidents.
What is file carving?
answerRecovering files from storage without relying on file system metadata.
What are file hashes?
answerUnique digital fingerprints (MD5, SHA-1, SHA-256) used to verify file integrity.
Why is hashing important?
answerHelps verify that evidence has not been modified.
What is timeline analysis?
answerOrganizing events chronologically to understand system activity.
What is disk forensics?
answerAnalyzing storage devices to identify evidence.
What is log analysis?
answerReviewing system and application logs to identify suspicious activities.
What is incident response?
answerProcess of identifying, containing, investigating, and recovering from security incidents.
What is malware analysis?
answerStudying malicious software to understand its behavior and impact.
What is network forensics?
answerAnalyzing network traffic and logs during investigations.
Advanced forensics Q&A
Complex topics like ransomware investigation, live vs dead analysis, and cloud forensics.
How to investigate a ransomware incident?
answer- Identify affected systems
- Preserve evidence
- Collect logs
- Analyze activity timeline
- Determine infection source
- Document findings
What is live analysis?
answerExamining a running system before shutdown.
What is dead analysis?
answerInvestigating a system after it has been powered down.
Common challenges in digital forensics?
answer- Encryption
- Large data volumes
- Anti-forensics techniques
- Cloud storage
- Evidence preservation
What is cloud forensics?
answerInvestigating evidence stored in cloud environments.
What is mobile forensics?
answerCollecting and analyzing evidence from mobile devices.
How to verify evidence integrity?
answerBy calculating and comparing hash values throughout the investigation.
What is forensic reporting?
answerDocumenting findings, evidence, methodology, and conclusions.
What is an artifact in forensics?
answerTraces of user or system activity: browser history, event logs, temporary files, registry data.
Why is documentation important?
answerEnsures investigations are repeatable, defensible, and understandable.
