Gartner on Software Defined Security

Neil MacDonald on Software Defined Security:

Here’s what I propose: “Software defined” is about the capabilities enabled as we decouple and abstract infrastructure elements that were previously tightly coupled in our data centers: servers, storage, networking, security and so on.

I believe to truly be “software-defined”, these foundational characteristics must be in place

Abstraction – the decoupling of a resource from the consumer of the resource (also commonly referred to as virtualization when talking about compute resources). This is a powerful foundation as the virtualization of these resources should enable us to define ‘models’ of infrastructure elements that can be managed without requiring management of every element individually.

Instrumentation – opening up of the decoupled infrastructure elements with programmatic interfaces (typically XML-based RESTful APIs).

Automation – using these APIs, wiring up the exposed elements using scripts and other automation tools to remove “human middleware” from the equation. This is an area where traditional information security tools are woefully inadequate.

Orchestration – beyond script-based automation, automating the provisioning of data center infrastructure through linkages to policy-driven orchestration systems where the provisioning of compute, networking, storage, security and so on is driven by business policies such as SLAs, compliance, cost and availability. This is where infrastructure meets the business.

I will surely quibble on the details when I publish my own research on the topic, but Neil’s take is excellent.

The key piece we need ASAP is security product APIs. You don’t want to know the ugliness which security abstraction and automation startups need to go through for even the most mundane tasks.
