Collecting and Aggregating Risk Data

Risk data and treatment plans · 1 min read

Where risk data comes from

Risk data sources: incidents and losses, control tests, audit findings, KRIs and tools, threat intelligence, external loss data, business input.

Normalise, then aggregate

Collect, normalise, validate, aggregate, analyse.

Different sources measure things differently. Normalise them to common scales, units, periods and categories before aggregating, or the totals mean nothing.

What aggregation reveals

  • Several medium risks on one critical supplier.
  • The same control weakness across many systems.
  • A business unit with many overdue actions.
  • Risk rising in one category over several quarters.

Example. Three business units each rated their reliance on one cloud identity provider as medium. Aggregated, it was the organisation’s largest single point of failure, and it became a board-level risk.

How the exam asks about it

Benefit of aggregationReveals concentrations and trends

Several small risks on one supplierConsider their combined effect

In short

  • Risk data comes from incidents, control tests, audits, KRIs and tools, threat intelligence, external loss data and the business.
  • Normalise data (common scales, units, periods and categories) before aggregating it.
  • Aggregation by process, system, supplier or category reveals concentrations individual items hide.
  • Automate collection where possible to improve timeliness and reduce errors.
  • Every data source should have a known owner and definition.

Exam traps

  • Adding up scores from different scales.
  • Relying on a single data source.
  • Collecting data nobody uses for decisions.
  • Missing concentrations by looking only at individual risks.
