With so many people investing in the cloud to bring server costs down, it would seem obvious that the more people working on the same network, the more vulnerable it becomes.
Many service providers understand this, but have put the burden on their customers to keep information secured.
From The Wall Street Journal:
"The majority of cloud service providers do not consider security as one of their most important responsibilities according to a surprising survey released yesterday.
"The survey of 127 cloud service providers, 24 in six European countries, the others in the U.S., by the U.S.-based Ponemon Institute found that a majority of providers believe it is their customer’s responsibility to secure data."
