Techniques:
- Data recovery
- Log analysis
- Network traffic examination
Tools:
- Disk imaging software
- File carving tools
- Memory analysis tools
Challenges:
- Maintaining evidence integrity
- Dealing with encrypted data
- Keeping up with evolving attack methods
Importance:
- Understand security vulnerabilities
- Prevent future attacks
- Support legal proceedings
Computer forensics is crucial for cybersecurity incident response.
