We are building a data center, which I understand would be a dark site in terms of our ISO certification. And that we just need to show that we have done our due diligence when it comes to ISO, I looked at one the other day that is not ISO certified but is hipaa certified as well as OIXA, SOC and something else. What troubles me is the fact that at on the data center floor there are two exits to the outside. Would this be a problem for ISO 27000 and what is the guidance?
