About this interactive

Attestation means evidence or proof. In an audit, it is the proof that the company is really doing what it set out to do. The lesson's example: an external auditor asks for a list of everyone who left last month, picks one, two or more names from it, and asks for proof that each person's account was shut off, and when. The company then shows, from its own systems, that the account was decommissioned, de-provisioned or disabled. That record is the proof that the company follows its policy. What counts is a record that shows the account's state and the date it changed: a log entry, the system's change history, a dated export or screenshot, an audit trail. What does not count is anything that says what should happen or what someone believes happened: the policy itself, the written procedure, a plan to check later, an open request, someone's assurance, or the list of leavers on its own. Security+ lists attestation among the types and purposes of audits and assessments.
