  • The Processes include: Specification Development Process : After a tool category and at least one tool is selected by the steering committee NIST and law enforcement staff develops a requirements, assertions and test cases document (called the tool category specification). The tool category specification is posted to the web for peer review by members of the computer forensics community and for public comment by other interested parties. Relevant comments and feedback are then incorporated into the specification. Finally a test environment is designed for the tool category. Tool Test Process : After a category specification has been developed and a tool selected, NIST goes ahead with the test process. It acquires the tool to be tested, reviews the tool documentation, selects relevant test cases depending on features supported by the tool, develops the test strategy, executes tests and finally produces test report. Steering Committee and Vendor, then reviews the test report. At the end, NIST posts support software & test report to web.

Computer Crimes Task Force : An FBI agent takes a call from an Internet scam victim. Down the hall in a computer lab, a police detective poses undercover as a teenage girl in an online chat room. Steps away, a forensic examiner is breaking passwords and decrypting files on a suspected hacker’s computer. Internet Crime Complaint Center (IC3) [13]: The FBI and the National White Collar Crime Center have set up a clearinghouse for triaging cyber crime complaints called the Internet Crime Complaint Center, or IC3. Based in West Virginia, it works closely with a range of law enforcement agencies and private sector organizations.

    • 8. What do we do?

        • Start dumping all mails at Server
        • Freeze address books for all laptops

        • A means to commit the crime
        • A motive to commit the crime
        • An opportunity to commit the crime
    • 54. Characteristics of an Evidence
      • An Evidence must be:
        • Admissible
          • In front of law in “proving” documents and copies.
        • Authentic
          • In linking data to specific individuals and events

          • In terms of the reliability of the computer process
        • Complete
          • With a full story of particular circumstances.

    • 56. Cyber vis-à-vis non-Cyber Evidence
      • Computer Evidence must carry the characteristics of ‘Evidence’
      • Yet, Computer Evidence distinguishes itself as:
        • Computer data is mutable
          • Easily alterable without trace
          • Can change during evidence collection
          • Cannot be read by humans
          • Can create evidence as well as record it
          • Is based on technology that changes often.
        • Cyber Evidencing creates many opportunities
          • It provides threats as many commercial transactions are recorded
          • It is much easier to trace a person’s history and activities
          • Computer-assisted investigation methods have become possible.

      • Analysis
      • Presentation
    • 68. Identification
      • The first step in the forensic process.
      • Process for Recovery Guided by
        • What evidence is present
        • Where it is stored and
        • How it is stored
      • Electronic Stores can be
        • Personal computers
        • Mobile phones
        • PDAs
        • Smart Cards …
      • Key Parameters in Identification
        • Type of information
        • Format
    • 69. Preservation
      • Critical element in the forensic process.
      • Examination must be done in least intrusive manner.
      • If change is inevitable it is essential that the nature of, and reason for, the change can be explained.
      • Alteration to data must be accounted for and justified.
    • 70. Analysis
      • The extraction, processing and interpretation of digital data –regarded as the main element of cyber forensics.
      • Once extracted, digital evidence usually requires processing before it can be read by people.
      • When the contents of a hard disk drive are imaged, the data contained within the image needs to be extracted in a humanly meaningful manner.
      • The processing of the extracted product may occur as a separate step, or it may be integrated with extraction.
    • 71. Presentation
      • Involves the actual presentation in a court of law.
      • Depends on
        • The manner of presentation,
        • The expertise and qualifications of the presenter
        • The credibility of the processes employed to produce the evidence being tendered.
    • 72. Word of Caution!
      • Debugging is not Forensic!
        • An Approach to Analysis
      • Audit Trail is not Forensic!
