3. THE FIELD OF
COMPUTER FORENSICS
What is Computer Forensics?
 Computer forensics involves the preservation,
identification, extraction, documentation, and
interpretation of computer media for evidentiary
and root cause analysis
 Computer forensics is the process of identifying,
preserving, and analyzing data and technical items
for evidence that will be used in court

4. THE FIELD OF
COMPUTER FORENSICS
Used to obtain potential legal evidence
Evidence might be required for a wide range of computer
crimes and misuses
Multiple methods of computer forensics are:
 Discovering data on computer system
 Recovering deleted, encrypted, or damaged file information
 Monitoring live activity
 Detecting violations of corporate policy
Information collected assists in arrests, prosecution,
termination of employment, and preventing future illegal
activity

5. THE FIELD OF
COMPUTER FORENSICS
Example:-
Recovering thousands of deleted emails
Performing investigation post employment
termination
Recovering evidence post formatting hard
drive

10. STEPS OF COMPUTER
FORENSICS
 According to many professionals, Computer Forensics is a four (4) step process
Acquisition
 Physically or remotely obtaining possession of the computer, all network
mappings from the system, and external physical storage devices
Identification
 This step involves identifying what data could be recovered and
electronically retrieving it by running various Computer Forensic tools and
software
suites

11. STEPS OF COMPUTER
FORENSICS
Evaluation
 Evaluating the information/data recovered to
determine if and how it could be used again the
suspect for employment termination or prosecution
in court
Presentation
 This step involves the presentation of evidence discovered in a manner
which is understood by lawyers, non-technically staff/management, and
suitable as evidence as determined by United States and internal laws

COLLECTING EVIDENCE

18. USES OF COMPUTER
FORENSICS
 Criminal Prosecutors
 Rely on evidence obtained from a computer to prosecute
suspects and use as evidence
 Civil Litigations
 Personal and business data discovered on a computer can be
used in fraud, divorce, harassment, or discrimination cases
 Insurance Companies
 Evidence discovered on computer can be
used to mollify costs (fraud, worker’s
compensation, arson, etc)

19. USES OF COMPUTER
FORENSICS
