Professional Ethics & Standards Flashcards

A digital investigator is presented with a forensic image whose hash value does not match the original evidence hash. This is most significant because:

Answer: It indicates the forensic image may have been altered, threatening evidentiary integrity

A hash mismatch indicates the forensic copy does not exactly match the original, which can render evidence inadmissible and constitutes a chain of custody failure.

Which action best demonstrates professional ethical conduct when an investigator is uncertain about the legal authority to seize a particular device?

Answer: Leave the device and consult with legal counsel before proceeding

When legal authority is uncertain, investigators must consult counsel before acting to prevent evidence suppression and personal legal liability.

An investigator is deposed and asked about weaknesses in their methodology. Ethically, the investigator should:

Answer: Answer honestly and explain the limitations of the methodology used

Ethical investigators acknowledge methodological limitations honestly under oath; denying known weaknesses is dishonest and can constitute perjury.

The principle of 'non-repudiation' in digital forensics ethics primarily ensures that:

Answer: An investigator's actions and findings are attributable and verifiable to them

Non-repudiation means the investigator's documented actions can be verified and cannot be denied, supporting accountability and integrity of the process.

A court orders an investigator to turn over their working notes and examination logs. The investigator should:

Answer: Comply with the court order and provide all requested materials

Court orders are legally binding; failure to comply constitutes contempt of court, and destruction of ordered materials is obstruction of justice.

When an investigator accepts a contingency fee arrangement (payment only if the client wins), this most directly violates which ethical principle?

Answer: Impartiality and independence

Contingency fees create a financial incentive to reach a particular outcome, directly compromising the investigator's required objectivity and impartiality.

Under professional ethics standards, an investigator who learns of a colleague's serious misconduct in handling evidence is obligated to:

Answer: Report it through appropriate professional or legal channels

Professional ethics codes require investigators to report serious misconduct that could harm the integrity of the justice system or public trust in the profession.
