Internal audit

Answer: As an ISMS implementer, such situation should be avoided, otherwise you could have problems at the certification audit. The best course of action is that the internal auditor should be a different person from the implementer, because according ISO 27001, you must ensure objectivity and the impartiality of the audit process, so you should not audit your own activities as information security manager, including ISO 27001 implementation.
