What services are you referring to in Disaster Recovery Services? What information would you be storing that you think might be cause for exploitation? This will better help me to understand your question and concern. I have been working in disaster response for many years and for the most part, believe that coordinating response using cloud-based technologies poses little threat; however that depends on the information you plan to share. There are certain items that you'd want to be very careful with regarding patient care data, child and minor related safety issues etc.
