If you are grappling with novel issues, or have further ISO27k-related questions that you would like answered, please join and post your queries on the ISO27k Forum. We reserve the right to reproduce or plagiarise common or generally useful questions and answers here for the benefit of all our visitors, albeit anonymously and in a generic manner.

We are neither infallible nor all-knowing so please bear with us if we or other ISO27k Forum members take a while to respond, are sometimes a bit vague, and make mistakes. Occasional responses are contradictory ... and those are sometimes the most interesting. If you are experienced in this field and have better, more precise, more accurate or simply alternative answers to the questions in this FAQ, by all means bring them up on the Forum or get in touch.

Pragmatic hints and tips from those of you who have actually been right through the process of designing, implementing and using an ISO27k ISMS are particularly welcome. There are practical limits to the amount of free advice we can provide!
