I have a presentation I have to put together in one of my classes. The topic I have been?

assigned to is "Information Systems Security, Cyber-terrorism, and Disaster Recovery." I was looking for suggestions as to how I can research this because the way I see it, these are 3 different things (although I know they relate to each other in some way). We have to select a specific area within our topic, but this is kind of difficult when you have more than one subject within your topic. Say for instance, my topic was Computer security, I would have to select an area within that topic (e.g. biometric identification). With that being said, the topic I'm assigned to is not like this (Information Systems Security, Cyber terrorism, and Disaster Recovery). What specific area can I talk about within this topic?? Any suggestions would be greatly appreciated.
