The document discusses digital forensics, including what it is, types of computer crimes, tools used like FTK and Encase, procedures that must be followed, and examples of cases like Enron and United States vs Ivanov. Digital forensics involves recovering and investigating digital evidence from devices and can be used to find deleted data, track locations, and discover information through tools like forensic software. Proper seizure and collection of evidence must adhere to legal standards like using a write blocker.

2. Agenda
- What is Digital Forensics?
- Types of computer crimes
- Tools
- Procedures
- Cases
- Problems

3. What is digital forensics?
- Also referred to as digital forensic science
- It is a branch of forensic science that
ecompasses the recovery and investigation
of material found in digital devices
- Growth of computers and computer crime in
the 80's
- The Computer Fraud and Abuse Act (1986)
- Today, 95% of crime involves
a digital device in some way

4. Types of Crimes
-Hacking
-Phishing
-Viruses
-Identity Theft
-Cyber Stalking

5. Focus
-Digital Forensics is focused on gathering
evidence that can include:
-Tracking Movements
-Discovering Data
-Recovering Data
-Also, can be used to recover text messages
and information from other devices.

6. Tools

7. Forensic Toolkit (FTK)

8. Encase

9. FTK vs Encase
- Both of these programs have similar functions
and accepted in court.
-FTK may be too simple and does not require
much knowledge of forensics.
-Encase costs around $3,600
-FTK costs around $3,000

10. Procedure
-Seizure must adhere to the fourth amendment
-All data must be collect with the use of a write
blocker

11. Enron
-Largest digital forensics investigation to date
-31 terabytes of data
-roughly 8 billion pages of text
-After 5 years, the search yielded enough
information to convict many of those involved
in fraud including members at the top of the
company

12. Love Bug Virus
-Created in Onel De Guzman in 2000
-Spread through emails
-Virus cost an estimated 7 billion dollars worth
of damage
-Guzman was from the Phillipines
-They got a search warrant but did not
prosecute him

13. United States vs Ivanov
-FBI was able to trace attacks on major US
businesses to Aleksey Ivanov
-They were unable to make the arrest due to
jurisdiction
-Ivanov was lured to the US by inviting him to
interview for a fake company
-He was then arrested
-Facing up to 90 years in prision if
found guilty on all charges

14. Casey Anthony
-Testimony by a computer science expert who
discovered searches for:
-"chloroform"
-"neck breaking"
-"how to make chloroform"
-Could not be linked to Anthony
-Considered Circumstantial and was dismissed

15. Conclusion
-The definition of digital forensics
-Focus
-Software and hardware used
-Procedures
-Cases and problems associated with them
