Internal or External Audit?

About this interactive

The Auditing and Assessments lesson opens with the Dunning-Kruger effect: someone who knows a little about a subject tends to think they know more than they do, because they lack the context to see its full depth. Security is like that, which is why it needs to be assessed. Internal audits: even people who know a lot can miss things when they are deep in the technical and implementation detail. An internal audit steps back to look at the whole picture and at compliance. The lesson names a committee that reviews everything and a self-assessment the business runs on itself. Staff from inside the organisation do the looking, including an internal audit team and the board's audit committee. External audits: an examination or assessment by a third party, independent of the company, so it does not share the company's blind spots. Regulations may require one: a regulator or examiner, a qualified assessor for a payment card standard, an independent firm for an attestation. The test for each card is who does the looking. Someone inside the organisation, however senior, is internal. Someone from outside it, hired or sent, is external.

What you'll learn

Classify an audit or assessment as internal (a committee, staff or self-assessment within the organisation) or external (a regulator, examiner or independent third party)
Explain why outside assessment matters: people too close to the work, or who know only a little, can overestimate how well security is done

Key terms

Internal Audit: A self-directed review conducted within an organization to assess the effectiveness of security controls and ensure policy compliance.
External Audit: An independent assessment performed by a third party to evaluate an organization's cybersecurity posture and regulatory compliance.
Self-Assessment: An internal audit in which an organization evaluates its own processes and controls; less costly than external audits but limited by potential bias and conflicts of interest.
