A recent Sys-Con Media report said security in virtualized data centers can be much more difficult than traditional environments. However, security systems designed with virtualization in mind could solve many of the current issues.
According to the report, traditional security involves using a system of firewalls in the data center's LAN and WAN networks. Typically, a firewall is placed on every server rack and on all information entering and exiting the data center, limiting a security breach's ability to spread.
In a virtual environment, each of those physical servers could contain hundreds of virtual machines. As a result, the report said security for virtualized systems, such as a virtual private server, could spread to thousands of servers without leaving the rack.
Because of this complexity, the report said security systems that are designed to place firewalls in the partitions between virtual machines are essential to prevent intra-server corruption.
A recent report from Forrester Research found businesses using cloud computing and other hosted systems frequently use single password log-in systems, another traditional security measure that no longer meets basic needs. The report said organizations need to develop more advanced log-in procedures to improve the security of their hosted and cloud systems.
