Study Notes
Digital Forensics Process
- Gather data from suspect's computer to assess evidence for crimes or policy violations.
- Prepare a case by compiling a collection of evidential materials for court or inquiries.
Evidence Preservation
- Investigate suspect’s computer and preserve evidence on a separate system to prevent data loss.
- Follow accepted procedures before beginning the investigation to ensure reliability of findings.
Methodical Approach
- Document the chain of custody, tracking the evidence from discovery to case closure or court proceedings.
- Systematic approach aids in comprehensive information gathering and thorough evaluation of evidence.
Case Requirements
- Identify the type of investigation by outlining case details: nature of the case, available evidence, and evidence locations.
Investigation Planning
- Determine required evidence and create a specific step-by-step plan for collection, analysis, and chain of custody establishment.
Securing Evidence
- Use reliable products to ensure security of computer evidence while avoiding damage to components.
- Handle computer components carefully to prevent static electricity interaction, which can corrupt digital data.
Best Practices for Evidence Handling
- Utilize antistatic bags for safe evidence collection.
- Consider wearing an antistatic wrist strap while working on computer hardware to minimize risk of static damage.
Digital Forensics Overview
- The digital landscape has become more accessible, leading to a greater need for standardized digital forensics processes.
- Digital forensics has evolved from basic data securing to a comprehensive analysis of digital information for legal purposes.
- It involves the application of computer science alongside investigative procedures.
Definition and Importance
- Digital forensics focuses on analyzing digital evidence that holds probative value, typically stored or transmitted in binary form.
- Essential elements include:
- Proper search authority
- Maintaining a chain of custody
- Mathematical validation (e.g., hash functions)
- Utilization of validated tools
- Processes ensuring repeatability
- Detailed reporting and potential expert testimony
Areas of Focus
- Digital forensics spans not only investigative cases but also aspects of research and incident response.
- Incident response prioritizes asset protection and situation containment rather than pursuing prosecution or identifying offenders.
- Research in digital forensics often does not focus on the prosecution or the evidential validity of findings.
Target Audience
- The content is specifically tailored for digital forensics investigators and examiners working across civil, criminal, and administrative domains.
