The Virtualization Practice

Tag Archive for more than firewalls

When we look at the secure hybrid cloud, there seems to be a missing piece, a piece that is used to validate identity via the role based access control assigned to applications, data, and systems allowed to access that is dynamic instead of normal static firewall rules that are either port or vm-centric. The software defined data center needs security to move with it and not remain static. Yes we could manipulate the rules on the fly, but those manipulations require that we know who is using a particular VM at a given time and in the case of a server, the VM could be used by more than one user at a time, so we need something more dynamic. Privileged access to data needs to be enforced throughout the stack and not just within an application or by encrypting data. This is a key component of the software defined data center.
