Project 3 Investigative Conclusion And Testimony

FINAL PROJECT - Investigative Conclusion and Testimony · No directly quoted material may be used in this project paper. · Resources should be summarized or paraphrased with appropriate in-text and Resource page citations. *Read the parts of each section of this project carefully as you are being asked to answer questions assuming different roles for different questions.

SECTION I

In the course of this investigation you, as the Information Security Analyst for Provincial Worldwide, have or will need to interview (or perhaps "interrogate") several people to provide context for the evidence you have collected as well as the rational for your searches. Ms. McPherson and Provincial Worldwide management are asking for everything to be documented and would like you to provide them responses to the following pieces of information:

  1. Provide a list of people you believe should be interviewed for this investigation and how they relate to the investigation. What information could they possibly supply?
  2. Provide a narrative description of the interview setting and the intended process, before, during, and following the interview (remember that depending on the type of interview, the setting may be different).
  3. Explain to the management why these stages are important to a successful interview and investigation.

SECTION II

For the purpose of the first part of this Section, you are still the Information Security Analyst for the company. Consider this project a continuation of the work you performed in Projects #1 and #2. After seeing you search Mr. Belcamp’s work area and take several pieces of evidence, Ms. Victoria Evans who works in the office across the hall, comes forward with an odd story. Ms. Evans states that she is Mr. Belcamp’s girlfriend, but lately things in their relationship had begun to sour. She produces a thumb drive she says Mr. Belcamp gave her earlier that day. She tells you Mr. Belcamp told her to “keep it safe” and asked her to take it home with her at the end of the day.

Ms. Evans tells you she really likes her job at Provincial Worldwide and has no interest in being wrapped up in whatever Mr. Belcamp has done to invite negative attention.

  1. The laboratory has asked you to write a short summary of what information you want them to look for on the submitted thumb drive. Identify, for the lab, what digital or non-digital evidence you would like them to look for and explain why that evidence would be important to the case.
  2. Because you are the most familiar with the investigation, Ms. McPherson is asking you to brainstorm all the locations outside of Mr. Belcamp's immediate workspace where pertinent digital evidence might be found to help with your case. Identify all of these locations, including places where police would have to be involved to search. Identify what places are legal for the company to search, and which ones would require police involvement. Support your inclusion of each location with a short description of what type of evidence might be found there.
  3. Now, assume a different character for the next segment of the assessment. You are a forensic examiner at the Provincial Worldwide lab. Mr. Stephen Bishop, a newly promoted Regional Security Operations Manager, sent an email to Ms. McPherson which is forwarded to you. Write a response to the email that explains the importance of forensic readiness and nominates three forensic examination/analysis software tools that meet criminal justice standards under the Daubert Standard. Construct a table with tool names, manufacturers, capabilities, and how they meet Daubert standards.
  4. After receiving the thumb drive, you, as the forensic examiner, must make a forensic image before examining the data. Document the step you take prior to making the image and explain why this step is important for your case.
  5. Using hash values, explain what a hash value is, how you used it to identify the source code on the thumb drive, and an additional use of hash values in digital forensics, suitable for explaining to a judge and jury.
  6. Upon discovering the source code and evidence suggesting email transmission, do you recommend reporting the crime to law enforcement? Why or why not? Are private companies required to report crimes?
  7. Describe additional steps to prove the source code was sent to Mr. Belcamp’s personal email address.
  8. After reporting the crime, you are called to testify as an expert witness. Explain the significance of being qualified as an expert witness and how it differs from a fact witness.
  9. Mr. Belcamp’s attorney questions your impartiality, referencing your personal blog. Respond in a transcript style, addressing how your analysis remains unbiased and why your work should be accepted as credible evidence.

    Paper For Above instruction

    Introduction

    The role of an information security analyst in digital forensic investigations is pivotal in uncovering and documenting evidence related to cybercrimes and data breaches. Proper interview strategies, evidence collection methodologies, forensic analysis, and expert testimonies form the backbone of successful investigations. This paper addresses a comprehensive investigation scenario at Provincial Worldwide, covering interview procedures, evidence handling, forensic tools, evidence analysis, legal considerations, and court testimony procedures.

    Section I: Interview Planning and Execution

    Effective interviews are crucial in gathering contextual information. The interviewees should include the IT department head, Human Resources, and Mr. Belcamp’s direct supervisor. Each provides insights into the suspect’s activities, possible motives, and access to digital resources. The interview setting should be a private, sterile environment conducive to open dialogue, recorded appropriately and conducted respectfully. Following the interview, a written record ensures accountability. These stages ensure the integrity of information obtained, minimize bias, and facilitate accurate analysis. Proper planning and process management increase the likelihood of obtaining credible and useful information.

    Section II: Digital Evidence and Forensic Analysis

    Part 1: Evidence on the Thumb Drive

    On the submitted thumb drive, forensic examiners should search for source code files, email drafts, and hidden or encrypted files. These artifacts are critical as they potentially contain proprietary source code, communication logs, and evidence of unauthorized data transfer. Identifying such files can directly establish intent, actions, and the scope of the breach.

    Part 2: External Digital Evidence Locations

    Potential locations outside Mr. Belcamp’s immediate workspace include personal devices (laptops and smartphones), network servers, cloud storage accounts, and email history archives. Locations requiring police involvement include search warrants for personal email accounts and cloud services. Company-legal searches include company servers, workstations, and assigned mobile devices. Each location’s evidence type varies, from stored source code, email logs, to access records, essential for reconstructing the timeline and scope of unauthorized activities.

    Part 3: Forensic Tool Selection

    The forensic examiner must select tools such as EnCase Forensic, FTK (Forensic Toolkit), and X-Ways Forensics. These meet Daubert standards by demonstrating scientific validity, peer review, error rate, and acceptance in the forensic community:

    Tool Name Manufacturer Capabilities Daubert Standard Explanation
    EnCase Forensic Guidance Software (OpenText) Comprehensive data acquisition, analysis, timeline generation Extensively validated in court, peer-reviewed, with documented error rates
    FTK (Forensic Toolkit) C Clarence Rapid evidence processing, data carving, email analysis Widely used, recommended by legal community, supports validated procedures
    X-Ways Forensics X-Ways Software Technology Efficient imaging, file recovery, detailed analysis Proven reliability, peer-reviewed, with transparent validation processes

    Part 4: Creating a Forensic Image

    Before analyzing the thumb drive, the examiner creates a bit-by-bit forensic image of the evidence. This process involves verifying that the drive is write-protected and generating hash values to establish integrity. This step ensures that the original evidence is preserved unaltered, maintaining its admissibility in court.

    Part 5: Hash Values and Evidence Identification

    A hash value is a unique digital fingerprint generated through cryptographic algorithms like MD5 or SHA-256. It allows the examiner to confirm that the evidence has not been altered. By matching hash values, the examiner verified that the copied source code was identical to the original, establishing chain of custody and integrity. Hashes also help detect file modifications, duplications, and ensure evidence authenticity, which is vital in court to demonstrate unaltered evidence.

    Part 6: Reporting the Crime

    Given the presence of proprietary source code and evidence of potential email transmission, it is advisable to report the incident to law enforcement. Private companies are not legally mandated to report crimes unless specified by statutes or contractual obligations; however, reporting facilitates formal investigation and potential prosecution of cybercrimes, especially involving intellectual property theft.

    Part 7: Additional Evidence Collection

    Additional steps include analyzing email logs, server access records, and subpoenaing email service providers if necessary. These will help determine if evidence of the source code being emailed exists, providing a stronger case if prosecuted.

    Part 8: Expert Witness Significance

    Being qualified as an expert witness enables the examiner to testify about specialized technical knowledge, methodologies, and findings that a court cannot interpret without expertise. Unlike fact witnesses, who only state observed facts, expert witnesses offer opinions based on scientific and technical analysis, helping the court understand complex digital evidence.

    Part 9: Addressing Bias Allegations

    Responding to concerns about bias involves affirming that the analysis is based solely on scientific procedures, validated methods, and documented procedures, adhering to legal standards. Personal opinions or beliefs do not influence forensic findings; credibility stems from applying standardized methodologies, peer-reviewed tools, and transparent processes that withstand legal scrutiny.

    Conclusion

    This comprehensive investigation underscores the importance of meticulous interview processes, rigorous evidence handling, and validated forensic methods. Properly prepared expert testimony further enhances the credibility of findings in court. Adhering to legal standards and scientific validation ensures the integrity of digital forensic investigations and their role in upholding justice.
