Security: In the Cloud, For the Cloud & By the Cloud…
When my I interact with folks and they bring up the notion of “Cloud Security,” I often find it quite useful to stop and ask them what they mean. I thought perhaps it might be useful to describe why.
In the same way that I differentiated “Virtualizing Security, Securing Virtualization and Security via Virtualization” in my Four Horsemen presentation, I ask people to consider these three models when discussing security and Cloud:
- In the Cloud: Security (products, solutions, technology) instantiated as an operational capability deployed within Cloud Computing environments (up/down the stack.) Think virtualized firewalls, IDP, AV, DLP, DoS/DDoS, IAM, etc.
- For the Cloud: Security services that are specifically targeted toward securing OTHER Cloud Computing services, delivered by Cloud Computing providers (see next entry) . Think cloud-based Anti-spam, DDoS, DLP, WAF, etc.
- By the Cloud: Security services delivered by Cloud Computing services which are used by providers in option #2 which often rely on those features described in option #1. Think, well…basically any service these days that brand themselves as Cloud… 😉
At any rate, I combine these with other models and diagrams I’ve constructed to make sense of Cloud deployment and use cases. This seems to make things more clear. I use it internally at work to help ensure we’re all talking about the same language.
