In this article, Gary Anthes discussed several different aspects of network security in a cloud environment. He spoke with representatives from HP and IBM who discussed the security and management benefits of server virtualization. Unlike traditional server setups, virtualized machines can be cloned, migrated, and backuped without the user ever realizing anything unusual is going on.
In the second half of the article, Anthes discussed the difficulties of server side encryption. For example, when a user submits their credentials to log into a server, the username/password database needs to be decrypted first. These constant decryptions can give a performance hit to the sever, as well as make things insecure if the server were to be attacked.
