Security As A Service: “The Cloud” & Why It’s a Net Security Win
If you’ve been paying attention to the rash of security startups entering the market today, you will no doubt notice the theme wherein the majority of them are, from the get-go, organizing around deployment models which operate from “The Cloud.”
We can argue that “Security as a service” usually refers to security services provided by a third party using the SaaS (software as a service) model, but there’s a compelling set of capabilities that enables companies large and small to be both effective, efficient and cost-manageable as we embrace the “new” world of highly distributed applications, content and communications (cloud and mobility combined.)
As with virtualization, when one discusses “security” and “cloud computing,” any of the three perspectives often are conflated (from my post “Security: In the Cloud, For the Cloud & By the Cloud…“):
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…
What I’m talking about here is really item #3; security “by the cloud,” wherein these services utilize any cloud-based platform (SaaS, PaaS or IaaS) to delivery security capabilities on behalf of the provider or ultimate consumer of services.
For the SMB/SME/Branch, one can expect a hybrid model of on-premises physical (multi-function) devices that also incorporate some sort of redirect or offload to these cloud-based services. Frankly, the same model works for the larger enterprise but in many cases regulatory issues of privacy/IP concerns arise. This is where the capability of both “private” (or dedicated) versions of these services are requested (either on-premises or off, but dedicated.)
Service providers see a large opportunity to finally deliver value-added, scaleable and revenue-generating security services atop what they offer today. This is the realized vision of the long-awaited “clean pipes” and “secure hosting” capabilities. See this post from 2007 “Clean Pipes – Less Sewerage or More Potable Water?”
If you haven’t noticed your service providers dipping their toes here, you certainly have seen startups (and larger security players) do so. Here are just a few examples:
- Trend Micro
- Cisco (Ironport/ScanSafe)
- …and many more
As many vendors “virtualize” their offers and start to realize that through basic networking, APIs, service chaining, traffic steering and security intelligence/analytics, these solutions become more scaleable, leveragable and interoperable, the services you’ll be able to consume will also increase…and they will become more application and information-centric in nature.
Again, this doesn’t mean the disappearance of on-premises or host-based security capabilities, but you should expect the cloud (and it’s derivative offshoots like Big Data) to deliver some really awesome hybrid security capabilities that make your life easier. Rich Mogull (@rmogull) and I gave about 20 examples of this in our “Grilling Cloudicorns: Mythical CloudSec Tools You Can Use Today” at RSA last month.
Get ready because while security folks often eye “The Cloud” suspiciously, it also offers up a set of emerging solutions that will undoubtedly allow for more efficient, effective and affordable security capabilities that will allow us to focus more on the things that matter.
