Benford's Law

An expected distribution of first digits in many naturally occurring number sets; large deviations from that pattern in transaction amounts can indicate fabricated or manipulated figures.

Related: Data Analytics, Red Flag, Exception Report
Exception Report

Related: Data Analytics, Red Flag, Continuous Monitoring
Red Flag

Related: Fraud Triangle, Exception Report, Professional Skepticism
Continuous Monitoring

An automated, ongoing review of transactions and controls that flags problems close to the time they occur rather than months later during a periodic audit.

Related: Data Analytics, Exception Report, Internal Control
Computer-Assisted Audit Techniques (CAAT)

Software-based procedures, such as data extraction, matching, and recalculation, used to test entire populations of records instead of relying only on manual samples.

Related: Data Analytics, Exception Report, Continuous Monitoring
Chain of Custody

A documented, unbroken record of who handled an item of evidence, when, and where it was kept, so its authenticity can be defended later.

Related: Digital Forensic Imaging, Working Papers, Corroboration
Digital Forensic Imaging

Creating a verified, bit-for-bit copy of a device or storage medium so that analysis can proceed on the copy while the original stays preserved.

Related: Hash Value, Chain of Custody

Related: Digital Forensic Imaging, Chain of Custody

Related: Documentary Evidence, Testimonial Evidence, Admission
