Mixed Deck — All ACI Topics Flashcards

Which principle ensures that a forensic examination can be repeated by another qualified examiner with the same tools and produce the same results?

Answer: Reproducibility

Reproducibility is a core scientific and quality principle requiring that documented methods produce consistent results when repeated under the same conditions.

A forensic examiner is asked by their employer to alter timestamps in a report to make evidence appear more recent. The correct ethical response is to:

Answer: Refuse and document the request

Falsifying evidence is illegal and unethical; the examiner must refuse and document the request to protect themselves.

Which document type defines the step-by-step processes that forensic examiners must follow to ensure consistency and reproducibility?

Answer: Standard Operating Procedure (SOP)

SOPs provide detailed, standardized instructions that ensure all examiners perform analyses the same way, supporting reproducibility and quality.

Which SQLite database on an iPhone stores both SMS and iMessage communications?

Answer: sms.db

The sms.db SQLite database located at /var/mobile/Library/SMS/ on iOS devices stores all SMS text messages and iMessages, including sender/receiver data and timestamps.

What is the primary legal concern in digital forensics?

Answer: Ensuring evidence is obtained legally

The primary legal concern in digital forensics is ensuring that all evidence is obtained legally and in accordance with established laws and regulations. If digital evidence is collected without proper authorization, such as a warrant, or through illegal means, it may be deemed inadmissible in court. Adherence to legal procedures is fundamental to the integrity and success of any forensic investigation, protecting both the investigation and the rights of individuals.

During an investigation, a department head outside the need-to-know circle asks the investigator directly about case status. The best response is to:

Answer: Confirm the investigation exists but direct them to the designated case contact

Investigators should neither confirm full details nor deny the investigation to unauthorized parties — they should redirect to the designated case contact.

Which tool is commonly used for forensic analysis of digital devices?

Answer: Autopsy

Autopsy is a widely used forensic tool for analyzing digital evidence, allowing investigators to examine file systems, recover data, and analyze user activity.

In ISO/IEC 17025 compliance for forensic labs, what does the term 'measurement uncertainty' refer to?

Answer: A quantified range within which the true value of a measurement is expected to lie

ISO 17025 requires labs to estimate and report measurement uncertainty, acknowledging that no measurement is perfectly precise.

A risk mitigation plan identifies that patching a critical vulnerability will take 30 days. What should the organization implement in the interim?

Answer: Implement compensating controls to reduce exposure

Compensating controls (such as additional monitoring, network segmentation, or access restrictions) reduce risk exposure while a permanent fix is pending.

Which metric expresses the estimated financial loss an organization can expect from a specific risk in a given year?

Answer: Annualized Loss Expectancy (ALE)

ALE = SLE × Annual Rate of Occurrence (ARO), representing the yearly expected financial cost of a specific risk.

Which of the following best describes the appropriate level of detail in a technical forensic report appendix versus the executive summary?

Answer: The appendix contains detailed technical findings; the executive summary presents high-level impact and conclusions

Forensic reports are stratified so technical detail lives in appendices while executives receive impact-focused summaries.

During an internal fraud investigation, when should an investigator notify the subject that they are under investigation?

Answer: Only after all evidence is collected and legal counsel has authorized notification

Premature notification risks evidence destruction or subject flight, so notification should occur only after evidence collection and legal authorization.

A lab receives a request to expedite a case, and the supervisor suggests skipping the technical review step to save time. The correct response is:

Answer: Refuse, because technical review is a mandatory quality control step that cannot be skipped

Technical review is a mandatory quality gate that protects both the integrity of findings and the lab's accreditation status; no urgency justifies skipping it.

A new regulation impacts accessdata investigator legal & ethics procedures. What should a ACI professional do first?

Answer: Ensuring compliance with current regulatory requirements and standards

Ensuring compliance with current regulatory requirements and standards is the correct approach because effective accessdata investigator legal & ethics in the accessdata certified investigator field requires adherence to professional standards, evidence-based practices, and systematic methodology. This approach ensures consistent, high-quality outcomes while maintaining professional accountability.

A new regulation impacts accessdata investigator cybercrime investigation techniques procedures. What should a ACI professional do first?

Answer: Ensuring compliance with current regulatory requirements and standards

Ensuring compliance with current regulatory requirements and standards is the correct approach because effective accessdata investigator cybercrime investigation techniques in the accessdata certified investigator field requires adherence to professional standards, evidence-based practices, and systematic methodology. This approach ensures consistent, high-quality outcomes while maintaining professional accountability.

What is the primary goal of digital forensics?

Answer: To collect, preserve, and analyze digital evidence

Digital forensics involves collecting, preserving, and analyzing electronic evidence to support legal and investigative processes.

In the context of accessdata certified investigator, which principle most directly governs accessdata investigator data recovery & file evaluation practices?

Answer: Applying evidence-based methodologies with peer-reviewed support

Applying evidence-based methodologies with peer-reviewed support is the correct approach because effective accessdata investigator data recovery & file evaluation in the accessdata certified investigator field requires adherence to professional standards, evidence-based practices, and systematic methodology. This approach ensures consistent, high-quality outcomes while maintaining professional accountability.

When handling evidence under quality compliance standards, what is the significance of 'tamper-evident packaging'?

Answer: It provides visible indication if packaging has been opened or compromised after sealing

Tamper-evident packaging makes unauthorized access immediately visible, helping maintain and demonstrate evidence integrity through the chain of custody.

What does 'administrative review' of a forensic case file typically verify?

Answer: Completeness of documentation, proper forms, and compliance with administrative requirements

Administrative review focuses on procedural completeness — ensuring all required forms, signatures, and documentation are present and correct.

After completing a digital forensic investigation, an ACI investigator provides a final report with risk mitigation recommendations. What should the FINAL step of this reporting process include?

Answer: Providing actionable, prioritized recommendations and an executive summary

An effective forensic report concludes with prioritized, actionable recommendations and an executive summary so leadership can make informed risk mitigation decisions.
