Securing virtualized cloud systems has traditionally been challenging. It is crucial to secure not only the virtual servers but the infrastructure in which they reside. Traditionally external devices such as firewalls, IDS/IPS, access control, monitoring and other systems have been used to combat external threats. These are good at securing the LAN infrastructure and can be an effective barrier even when deployed to protect elements such as virtual switches, virtual I/O directors (such as Xsigo’s) and SAN infrastructure. However there’s a greater challenge in securing the virtual host systems themselves.
