Security and the Cloud
IBM has released a white paper that explores in some depth the issues around attaining adequate security in the cloud. A significant issue raised is that much of the security in cloud apps is often outsourced, which passes control, but not responsibility, to another party. Also, there is a visibility problem, in that it is often difficult to know just where the data is located, making it difficult to determine what security is in place to protect it.
The paper explores these and other issues, and is a valuable addition to the literature on the subject. In addition, the paper provides a useful explanation as to just what the cloud is and the variations that are in use.
