Definition of 'cyber resilience' and alignment with the 2018 FSB Cyber Lexicon

What the RLB Specialist Panel found

3. Definition of 'cyber resilience' and alignment with the 2018 FSB Cyber Lexicon

  • Question (paraphrased to protect IP): How does the CPMI-IOSCO 2016 Cyber Guidance define 'cyber resilience', and is that definition aligned with the 2018 FSB Cyber Lexicon?
  • Source regulation: Guidance on Cyber Resilience for Financial Market Infrastructures (CPMI-IOSCO 2016)
  • What AI assistants typically say: AI tools provided a specific verbatim-style definition of cyber resilience attributed to the 2016 guidance — "the ability to anticipate, absorb, adapt to, rapidly respond to, and recover from disruption caused by a cyber attack" — and went further to assert that the 2018 FSB Cyber Lexicon explicitly drew on the CPMI-IOSCO definition when establishing its own standardised terminology.
  • What the regulator actually says: The FSB Cyber Lexicon was published in November 2018, two years after the 2016 guidance. Its standardised definitions postdate the 2016 document and may not match how terms were used in 2016; no claim has been confirmed about whether the Lexicon directionally drew on the CPMI-IOSCO text or developed its definitions independently.
  • Why the AI went wrong: The AI produced an unverified specific definition attributed to the 2016 guidance and then asserted a directional influence relationship between the two documents — that the FSB Lexicon drew on the CPMI-IOSCO text — for which no evidentiary basis exists. Both the definition's attribution and the claimed influence are fabricated with apparent confidence.

Impact for Public Auditors in international jurisdictions advising on the Guidance on Cyber Resilience for Financial Market Infrastructures (CPMI-IOSCO 2016)

For public auditors checking definitions used in cyber policy and KRI work, an asserted consistency between the 2016 guidance and the November 2018 FSB Cyber Lexicon collapses a two-year gap in regulator vocabulary into a single asserted alignment. Audit testing that uses the asserted alignment as evidence of definitional grounding leaves the audit team exposed if the source documents are produced for inspection.
