I would like to know whether we can change our profile from information security auditor to quality management auditor. Is there any similarly between these two( ISO 27001 & ISO 9000) standards? If we can transition then how do we do it?
Answer: ISO 9001 and ISO 27001 have a lot of requirements in common, so you can either change your profile from ISO 27001 auditor to ISO 9001 auditor or accumulate both profiles.
To acquire the competencies for ISO 9001 auditor you should attend an auditor course, to learn about ISO 9001 requirements and how these requirements must be covered by audit techniques and methodologies. After that you should seek for opportunities to be a part of an ISO 9001 audit process to practice.
