Quick-Start: Cyber Space!
Draw out a linked diagram (a network) of what areas there are that have your valuable assets in them and the access routes, or communication links, between them.
Draw on it where your assets are located or stored and the routes they move along.
Include:
- Stores and processing devices: phones, laptops, computers, USB sticks, SD cards.
- What assets are held on these?
- Links that connect the devices that provide the routes your assets move along between devices.
- Include how users get to access the assets on those devices; how does a user get to the asset?
- Links that connect devices that could provide access to your assets.
- Defences - security precautions - that are already in place.
- Physical as well as virtual computer network locations
- Areas that you don’t control but your assets still exist in or move through.
This can be a very high level diagram, or even just a list of places, to start with; don’t worry about all the various detailed technical links.
