How software and network security can keep systems and data secure?

Diskless Networks tend to be more to do cloud based instead of a physical network. This means that when any information/data is stored than it will be sent to a network which tends to be considered as more of an external network. What makes this different to a physical network is that as soon as you leave the offie for the day then there is a chance that you may need to access that information whereas if it was a physical network than there ia chance that the user would not be able to acess the information/data that they may need to use.
