My Information Security Magazine Cover Story: “Virtualization security dynamics get old, changes ahead”

November 4th, 2013 2 comments

ISM_cover_1113This month’s Search Security (nee Information Security Magazine) cover story was penned by none other than your’s truly and titled “Virtualization security dynamics get old, changes ahead”

I hope you enjoy the story; its a retrospective regarding the beginnings of security in the virtual space, where we are now, and we we’re headed.

I tried very hard to make this a vendor-neutral look at the state of the union of virtual security.

I hope that it’s useful.

Why Amazon Web Services (AWS) Is the Best Thing To Happen To Security & Why I Desperately Want It To Succeed

November 29th, 2012 15 comments

Many people who may only casually read my blog or peer at the timeline of my tweets may come away with the opinion that I suffer from confirmation bias when I speak about security and Cloud.

That is, many conclude that I am pro Private Cloud and against Public Cloud.

I find this deliciously ironic and wildly inaccurate. However, I must also take responsibility for this, as anytime one threads the needle and attempts to present a view from both sides with regard to incendiary topics without planting a polarizing stake in the ground, it gets confusing.

Let me clear some things up.

Digging deeper into what I believe, one would actually find that my blog, tweets, presentations, talks and keynotes highlight deficiencies in current security practices and solutions on the part of providers, practitioners and users in both Public AND Private Cloud, and in my own estimation, deliver an operationally-centric perspective that is reasonably critical and yet sensitive to emergent paths as well as the well-trodden path behind us.

I’m not a developer.  I dabble in little bits of code (interpreted and compiled) for humor and to try and remain relevant.  Nor am I an application security expert for the same reason.  However, I spend a lot of time around developers of all sorts, those that write code for machines whose end goal isn’t to deliver applications directly, but rather help deliver them securely.  Which may seem odd as you read on…

The name of this blog, Rational Survivability, highlights my belief that the last two decades of security architecture and practices — while useful in foundation — requires a rather aggressive tune-up of priorities.

Our trust models, architecture, and operational silos have not kept pace with the velocity of the environments they were initially designed to support and unfortunately as defenders, we’ve been outpaced by both developers and attackers.

Since we’ve come to the conclusion that there’s no such thing as perfect security, “survivability” is a better goal.  Survivability leverages “security” and is ultimately a subset of resilience but is defined as the “…capability of a system to fulfill its mission, in a timely manner, in the presence of attacks, failures, or accidents.”  You might be interested in this little ditty from back in 2007 on the topic.

Sharp readers will immediately recognize the parallels between this definition of “survivability,” how security applies within context, and how phrases like “design for failure” align.  In fact, this is one of the calling cards of a company that has become synonymous with (IaaS) Public Cloud: Amazon Web Services (AWS.)  I’ll use them as an example going forward.

So here’s a line in the sand that I think will be polarizing enough:

I really hope that AWS continues to gain traction with the Enterprise.  I hope that AWS continues to disrupt the network and security ecosystem.  I hope that AWS continues to pressure the status quo and I hope that they do it quickly.

Why?

Almost a decade ago, the  Open Group’s Jericho Forum published their Commandments.  Designed to promote a change in thinking and operational constructs with respect to security, what they presciently released upon the world describes a point at which one might imagine taking one’s most important assets and connecting them directly to the Internet and the shifts required to understand what that would mean to “security”:

  1. The scope and level of protection should be specific and appropriate to the asset at risk.
  2. Security mechanisms must be pervasive, simple, scalable, and easy to manage.
  3. Assume context at your peril.
  4. Devices and applications must communicate using open, secure protocols.
  5. All devices must be capable of maintaining their security policy on an un-trusted network.
  6. All people, processes, and technology must have declared and transparent levels of trust for any transaction to take place.
  7. Mutual trust assurance levels must be determinable.
  8. Authentication, authorization, and accountability must interoperate/exchange outside of your locus/area of control
  9. Access to data should be controlled by security attributes of the data itself
  10. Data privacy (and security of any asset of sufficiently high value) requires a segregation of duties/privileges
  11. By default, data must be appropriately secured when stored, in transit, and in use.

These seem harmless enough today, but were quite unsettling when paired with the notion of “de-perimieterization” which was often misconstrued to mean the immediate disposal of firewalls.  Many security professionals appreciated the commandments for what they expressed, but the the design patterns, availability of solutions and belief systems of traditionalists constrained traction.

Interestingly enough, now that the technology, platforms, and utility services have evolved to enable these sorts of capabilities, and in fact have stressed our approaches to date, these exact tenets are what Public Cloud forces us to come to terms with.

If one were to look at what public cloud services like AWS mean when aligned to traditional “enterprise” security architecture, operations and solutions, and map that against the Jericho Forum’s Commandments, it enables such a perfect rethink.

Instead of being focused on implementing “security” to protect applications and information based at the network layer — which is more often than not blind to both, contextually and semantically — public cloud computing forces us to shift our security models back to protecting the things that matter most: the information and the conduits that traffic in them (applications.)

As networks become more abstracted, it means that existing security models do also.  This means that we must think about security programatticaly and embedded as a functional delivery requirement of the application.

“Security” in complex, distributed and networked systems is NOT a tidy simple atomic service.  It is, unfortunately, represented as such because we choose to use a single noun to represent an aggregate of many sub-services, shotgunned across many layers, each with its own context, metadata, protocols and consumption models.

As the use cases for public cloud obscure and abstract these layers — flattens them — we’re left with the core of that which we should focus:

Build secure, reliable, resilient, and survivable systems of applications, comprised of secure services, atop platforms that are themselves engineered to do the same in way in which the information which transits them inherits these qualities.

So if Public Cloud forces one to think this way, how does one relate this to practices of today?

Frankly, enterprise (network) security design patterns are a crutch.  The screened-subnet DMZ patterns with perimeters is outmoded. As Gunnar Peterson eloquently described, our best attempts at “security” over time are always some variation of firewalls and SSL.  This is the sux0r.  Importantly, this is not stated to blame anyone or suggest that a bad job is being done, but rather that a better one can be.

It’s not like we don’t know *what* the problems are, we just don’t invest in solving them as long term projects.  Instead, we deploy compensation that defers what is now becoming more inevitable: the compromise of applications that are poorly engineered and defended by systems that have no knowledge or context of the things they are defending.

We all know this, but yet looking at most private cloud platforms and implementations, we gravitate toward replicating these traditional design patterns logically after we’ve gone to so much trouble to articulate our way around them.  Public clouds make us approach what, where and how we apply “security” differently because we don’t have these crutches.

Either we learn to walk without them or simply not move forward.

Now, let me be clear.  I’m not suggesting that we don’t need security controls, but I do mean that we need a different and better application of them at a different level, protecting things that aren’t tied to physical topology or addressing schemes…or operating systems (inclusive of things like hypervisors, also.)

I think we’re getting closer.  Beyond infrastructure as a service, platform as a service gets us even closer.

Interestingly, at the same time we see the evolution of computing with Public Cloud, networking is also undergoing a renaissance, and as this occurs, security is coming along for the ride.  Because it has to.

As I was writing this blog (ironically in the parking lot of VMware awaiting the start of a meeting to discuss abstraction, networking and security,) James Staten (Forrester) tweeted something from @Werner Vogels keynote at AWS re:invent:

I couldn’t have said it better myself :)

So while I may have been, and will continue to be, a thorn in the side of platform providers to improve the “survivability” capabilities to help us get from there to there, I reiterate the title of this scribbling: Amazon Web Services (AWS) Is the Best Thing To Happen To Security & I Desperately Want It To Succeed.

I trust that’s clear?

P.S. There’s so much more I could/should write, but I’m late for the meeting :)

The Cuban Cloud Missile Crisis…Weapons Of Mass Abstraction.

September 7th, 2012 2 comments
English: Coat of arms of Cuba. Español: Escudo...

English: Coat of arms of Cuba. Español: Escudo de Cuba. Русский: Герб Кубы. (Photo credit: Wikipedia)

In the midst of the Cold War in October of 1962, the United States and the Soviet Union stood periously on the brink of nuclear war as a small island some 90 miles off the coast of Florida became the focal point of intense foreign policy scrutiny, challenges to sovereignty and political arm wrestling the likes of which were never seen before.

Photographic evidence provided by a high altitude U.S. spy plane exposed the until-then secret construction of medium and intermediate ballistic nuclear missile silos, constructed by the Soviet Union, which were deliberately placed so as to be close enough to reach the continental United States.

The United States, alarmed by this unprecedented move by the Soviets and the already uneasy relations with communist Cuba, unsuccessfully attempted a CIA-led forceful invasion and overthrow of the Cuban regime at the Bay of Pigs.

This did not sit well with either the Cubans or Soviets.  A nightmare scenario ensued as the Soviets responded with threats of its own to defend its ally (and strategic missile sites) at any cost, declaring the American’s actions as unprovoked and unacceptable.

During an incredibly tense standoff, the U.S. mulled over plans to again attack Cuba both by air and sea to ensure the disarmament of the weapons that posed a dire threat to the country.

As posturing and threats continued to escalate from the Soviets, President Kennedy elected to pursue a less direct military action;  a naval blockade designed to prevent the shipment of supplies necessary for the completion and activation of launchable missiles.  Using this as a lever, the U.S. continued to demand that Russia dismantle and remove all nuclear weapons as they prevented any and all naval traffic to and from Cuba.

Soviet premier Krustchev protested such acts of “direct aggression” and communicated to president Kennedy that his tactics were plunging the world into the depths of potential nuclear war.

While both countries publicly traded threats of war, the bravado, posturing and defiance were actually a cover for secret backchannel negotiations involving the United Nations. The Soviets promised they would dismantle and remove nuclear weapons, support infrastructure and transports from Cuba, and the United States promised not to invade Cuba while also removing nuclear weapons from Turkey and Italy.

The Soviets made good on their commitment two weeks later.  Eleven months after the agreement, the United States complied and removed from service the weapons abroad.

The Cold War ultimately ended and the Soviet Union fell, but the political, economic and social impact remains even today — 40 years later we have uneasy relations with (now) Russia and the United States still enforces ridiculous economic and social embargoes on Cuba.

What does this have to do with Cloud?

Well, it’s a cute “movie of the week” analog desperately in need of a casting call for Nikita Khrushchev and JFK.  I hear Gary Busey and Aston Kutcher are free…

As John Furrier, Dave Vellante and I were discussing on theCUBE recently at VMworld 2012, there exists an uneasy standoff — a cold war — between the so-called “super powers” staking a claim in Cloud.  The posturing and threats currently in process don’t quite have the world-ending outcomes that nuclear war would bring, but it could have devastating technology outcomes nonetheless.

In this case, the characters of the Americans, Soviets, Cubans and the United Nations are played by networking vendors, SDN vendors, virtualization/abstraction vendors, cloud “stack” projects/efforts/products and underlying CPU/chipset vendors (not necessarily in that order…)  The rest of the world stands by as their fate is determined on the world’s stage.

If we squint hard enough at Cloud, we might find out very own version of the “Bay of Pigs,” with what’s going on with OpenStack.

The “community” effort behind OpenStack is one largely based on “industry” and if we think of OpenStack as Cuba, it’s being played as pawn in the much larger battle for global domination.  The munitions being stocked in this tiny little enclave threatens to disrupt relations of epic proportions.  That’s why we now see so much strategic movement around an initiative and technology that many outside of the navel gazers haven’t really paid much attention to.

Then there are players like Amazon Web Services who, like China of today, quietly amass their weapons of mass abstraction as the industry-jockeying and distractions play on (but that’s a topic for another post)

Cutting to the chase…if we step back for a minute

Intel is natively bundling more and more networking and virtualization capabilities into their CPU/Chipsets and a $7B investment in security company McAfee makes them a serious player there.  VMware is de-emphasizing the “hypervisor” and is instead positioning they are focused on end-to-end solutions which include everything from secure mobility, orchestration/provisioning and now, with Nicira, networking.  Networking companies like Cisco and Juniper continue to move up-stack to deeper integrate networking and security along with service overlays in order to remain relevant in light of virtualization and SDN.

…and OpenStack’s threat of disrupting all of those plays makes it important enough to pay attention to.  It’s a little island of technology that is causing huge behemoths to collide.  A molehill that has become a mountain.

If today’s announcements of VMware and Intel joining OpenStack as Gold Members along with the existing membership by other “super powers” doesn’t make it clear that we’re in the middle of an enormous power struggle, I’ve got a small Island to sell you ;)

Me?  I’m going to make some Lechon Asado, enjoy a mojito and a La Gloria Cubana.

Is What We Need…An OpSec K/T Boundary Extinction-Level Event?

June 21st, 2012 1 comment

Tens of millions of Aons (a new quantification of time based on Amazon Web Services AMI spin-ups) from now, archeologists and technosophers will look back on the inevitable emergence of Cloud in the decade following the double-oughts and muse about the mysterious disappearance of the security operations species…

Or not.

The “Cloud Security, Meh!” crowd are an interesting bunch. They don’t seem to like change much.  To be fair, they’re not incentivized to.  However, while difficult, change is good…it just takes a lot to understand that some times.

It occurs to me that if we expect behavior to change in the way in which we approach “security,” it must start with a reset of expectations surrounding how we evaluate outcomes, how we’re measured, and most importantly the actual security leadership itself must change.

Most seasoned CxOs these days that have been in the business for 15+ years are in their late 30′s/early 40′s.  Most of “us” — from official scientifical research I have curated [at the bar] — came from System Administrator/Network Administrator roles back in the 80′s/90′s.

Now, what’s intriguing is that back then, “security” was just one functional component and responsibility of many duties slapped on the back of overworked and underfunded “router jockeys” or “unix neckbearders.”  Back in the day we did it all — we managed the network, massaged the Solaris/NT boxes, helped deploy and manage the apps and were responsible for “securing” it all as we connected stuff to the Internet.

You know, like, um, DevOps.

So today in larger organizations (notsomuch in smaller orgs/startups,) we have a raging rejection of this generalized approach to service delivery/IT by the VERY SAME individuals who arose phoenix-like from the crater left when the Internet exploded and the rampant adoption of technology and siloed operational models became “best practice.” Compliance didn’t help.  Then they got promoted.

In many cases then, the bristled reaction by security folks to things like virtualization, Cloud, Agile, DevOps, etc. is highly generational.  The up-and-coming rank-in-file digital natives who are starting to break into the industry will know these things as “normal,” much like a preschooler uses gestures on an iPad…it just…is.

However, their leadership — “us” — the 40+ year olds that are large and in charge are busy barking that youngsters should get off our IT lawn.  This is very much a generational issue.

So I think what that means is that ultimately we’re waiting for our own version of the K/T boundary extinction-level “opportunity,”  the horizon event at the boundary of the Cretacious/Tertiary periods 65 million years ago where almost all of the Earth’s large vertebrates — all dinosaurs, plesiosaurs, mosasaurs, and pterosaurs – suddenly became extinct.  Boom.  Gone.  Damned meteorites.

Now, unless the next great piece of malware can target, infect and destroy humans as we Bing/Google/click our way into stupidity (coming next week from Iran?) ala Stuxnet/Flame, we’re not going to see these stodgy C(I)SOs vanish instantly, but over the next two decades, we’ll see a new generation arise who think, act and believe differently than we do today…I just hope it doesn’t take that long.

This change…it’s natural. It’s evolution, and patterns like these repeat (see the theory of punctuated equilibrium) even in the face of revolution.  It’s messy.

More often than not, it’s not the technology that’s the problem with “security” when we hit one of these inflection points in computing. No, it’s the organizational, operational, cultural, fiscal, and (dare I say) religious issues that hold us back.  Innovation breeds more innovation unless it’s shackled by people who can’t think outside of the box.

That right there is what defines a dino/plesio/mosa/ptero-saur.

Come to think of it, maybe we do need an OpSec extinction-level event to move us forward instead of waiting 20 years for the AARP forced slide to Florida.

Or, in the words of Gunny Highway from Heartbreak Ridge, we must “Improvise, adapt and overcome.”

If that’s not a DevOps Darwinian double-entendre, I don’t know what is ;)

Don’t be a dinosaur.

Security As A Service: “The Cloud” & Why It’s a Net Security Win

March 19th, 2012 3 comments

Cloud Computing Image (Photo credit: Wikipedia)

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:

  1. 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.
  2. 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.
  3. 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:

  • Qualys
  • Trend Micro
  • Symantec
  • Cisco (Ironport/ScanSafe)
  • Juniper
  • CloudFlare
  • ZScaler
  • Incapsula
  • Dome9
  • CloudPassage
  • Porticor
  • …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.

When A FAIL Is A WIN – How NIST Got Dissed As The Point Is Missed

January 2nd, 2012 4 comments

Randy Bias (@randybias) wrote a very interesting blog titled Cloud Computing Came To a Head In 2011, sharing his year-end perspective on the emergence of Cloud Computing and most interestingly the “…gap between ‘enterprise clouds’ and ‘web-scale clouds’”

Given that I very much agree with the dichotomy between “web-scale” and “enterprise” clouds and the very different sets of respective requirements and motivations, Randy’s post left me confused when he basically skewered the early works of NIST and their Definition of Cloud Computing:

This is why I think the NIST definition of cloud computing is such a huge FAIL. It’s focus is on the superficial aspects of ‘clouds’ without looking at the true underlying patterns of how large Internet businesses had to rethink the IT stack.  They essentially fall into the error of staying at my ‘Phase 2: VMs and VDCs’ (above).  No mention of CAP theorem, understanding the fallacies of distributed computing that lead to successful scale out architectures and strategies, the core socio-economics that are crucial to meeting certain capital and operational cost points, or really any acknowledgement of this very clear divide between clouds built using existing ‘enterprise computing’ techniques and those using emergent ‘cloud computing’ technologies and thinking.

Nope. No mention of CAP theorem or socio-economic drivers, yet strangely the context of what the document was designed to convey renders this rant moot.

Frankly, NIST’s early work did more to further the discussion of *WHAT* Cloud Computing meant than almost any person or group evangelizing Cloud Computing…especially to a world of users whose most difficult challenges is trying to understand the differences between traditional enterprise IT and Cloud Computing

As I reacted to this point on Twitter, Simon Wardley (@swardley) commented in agreement with Randy’s assertions, but strangely what I found odd again was the misplaced angst by which the criterion of “success” vs “FAIL” that both Simon and Randy were measuring the NIST document against:

Both Randy and Simon seem to be judging NIST’s efforts against their lack of extolling the virtues, or “WHY” versus the “WHAT” of Cloud, and as such, were basically doing a disservice by perpetuating aged concepts rooted in archaic enterprise practices rather than boundary stretch, trailblaze and promote the enlightened stance of “web-scale” cloud.

Well…

The thing is, as NIST stated in both the purpose and audience sections of their document, the “WHY” of Cloud was not the main intent (and frankly best left to those who make a living talking about it…)

From the NIST document preface:

1.2 Purpose and Scope

Cloud computing is an evolving paradigm. The NIST definition characterizes important aspects of cloud computing and is intended to serve as a means for broad comparisons of cloud services and deployment strategies, and to provide a baseline for discussion from what is cloud computing to how to best use cloud computing. The service and deployment models defined form a simple taxonomy that is not intended to prescribe or constrain any particular method of deployment, service delivery, or business operation.

1.3 Audience

The intended audience of this document is system planners, program managers, technologists, and others adopting cloud computing as consumers or providers of cloud services.

This was an early work (the initial draft was released in 2009, final in late 2011,) and when it was written, many people — Randy, Simon and myself included — we still finding the best route, words and methodology to verbalize the “Why.” And now it’s skewered as “mechanistic drivel.”*

At the time NIST was developing their document, I was working in parallel writing the “Architecture” chapter of the first edition of the Cloud Security Alliance’s Guidance for Cloud Computing.  I started out including my own definitional work in the document but later aligned to the NIST definitions because it was generally in line with mine and was well on the way to engendering a good deal of conversation around standard vocabulary.

This blog post summarized the work at the time (prior to the NIST inclusion).  I think you might find the author of the second comment on that post rather interesting, especially given how much of a FAIL this was all supposed to be… :)

It’s only now with the clarity of hindsight that it’s easier to take the “WHY,” and utilize the “WHAT” (from NIST and others, especially practitioners like Randy) in a manner that is complementary so we can talk less about “what and why” and rather “HOW.”

So while the NIST document wasn’t, isn’t and likely never will be “perfect,” and does not address every use case or even eloquently frame the “WHY,” it still serves as a very useful resource upon which many people can start a conversation regarding Cloud Computing.

It’s funny really…the first tenet for “web-scale” cloud that AWS — the “Kings of Cloud” Randy speaks about constantly –  is “PLAN FOR FAIL.”  So if the NIST document truly meets this seal of disapproval and is a FAIL, then I guess it’s a win ;p

Your opinion?

/Hoff

*N.B. I’m not suggesting that critiquing a document is somehow verboten or that NIST is somehow infallible or sacrosanct — far from it.  In fact, I’ve been quite critical and vocal in my feedback with regard to both this document and efforts like FedRAMP.  However, this is during the documents’ construction and with the intent to make it better within the context within which they were designed versus the rear view mirror.

Cloud: The Turducken Of Computing? [Oh, and Happy Thanksgiving]

November 20th, 2011 3 comments

In these here United States Of ‘Merica, we’re closing in on our National Day of Gluttony, Thanksgiving.

As we approach #OccupyStuffedGullet, I again find myself quizzically introspective, however frightening the prospect of navel gazing combined with fatal doses of Tryptophan leaves me.

Reviewing the annual list of consumables for said celebration in conjunction with yet another interminable series of blog posts on “What Cloud *really* means for [insert target market here,]” I am compelled to suggest that what Cloud *really* means and *really* represents is…

A Turducken.

According to the Oracle of Mr. Wales, a Turducken is as follows:

turducken is a dish consisting of a de-boned chicken stuffed into a de-boned duck, which itself is stuffed into a de-boned turkey. The word turducken is a portmanteau of turkey, duck, and chicken or hen.

The thoracic cavity of the chicken/game hen and the rest of the gaps are stuffed, sometimes with a highly seasoned breadcrumb mixture or sausage meat, although some versions have a different stuffing for each bird.

I’ll leave it to you to map the visual to the…Oh, who am I kidding?

What does this *really* have to do with Cloud? Nothing, really, but I’m rather bloated with the resurgence of metaphors and analogs which seek to clarify new computing recipes in order to justify more gut-busting consumption, warranted or not, diets-be-damned.  But really…sometimes a dish is delicious in its simplicity and doesn’t need any garnish. ;)

In fact, this comparison isn’t really at all that accurate or interesting, but I found it funny nonetheless…

Frankly, it’s *really* just an excuse to wish you all a very merry ClouDucken Day :)

May your IT be stuffed and your waistline elastic.

VMware’s vShield – Why It’s Such A Pain In the Security Ecosystem’s *aaS…

September 4th, 2011 15 comments

I’ve become…comfortably numb…

Whilst attending VMworld 2011 last week, I attended a number of VMware presentations, hands-on labs and engaged in quite a few discussions related to VMware’s vShield and overall security strategy.

I spent a ton of time discussing vShield with customers — some who love it, some who don’t — and thought long and hard about writing this blog.  I also spent some time on SiliconAngle’s The Cube discussing such, here.

I have dedicated quite a lot of time discussing the benefits of VMware’s security initiatives, so it’s important that you understand that I’m not trying to be overtly negative, nor am I simply pointing fingers as an uneducated, uninterested or uninvolved security blogger intent on poking the bear.  I live this stuff…every day, and like many, it’s starting to become messy. (Ed: I’ve highlighted this because many seem to have missed this point. See here for example.)

It’s fair to say that I have enjoyed “up-to-the-neck” status with VMware’s various security adventures since the first marketing inception almost 4 years ago with the introduction of the VMsafe APIs.  I’ve implemented products and helped deliver some of the ecosystem’s security offerings.  My previous job at Cisco was to provide the engineering interface between the two companies, specifically around the existing and next generation security offerings, and I now enjoy a role at Juniper which also includes this featured partnership.

I’m also personal friends with many of the folks at VMware on the product and engineering teams, so I like to think I have some perspective.  Maybe it’s skewed, but I don’t think so.

There are lots of things I cannot and will not say out of respect for obvious reasons pertaining to privileged communications and NDAs, but there are general issues that need to be aired.

Geez, enough with the CYA…get on with it then…

As I stated on The Cube interview, I totally understand VMware’s need to stand-alone and provide security capacities atop their platform; they simply cannot expect to move forward and be successful if they are to depend solely on synchronizing the roadmaps of dozens of security companies with theirs.

However, the continued fumbles and mis-management of the security ecosystem and their partnerships as well as the continued competitive nature of their evolving security suite makes this difficult.  Listening to VMware espouse that they are in the business of “security ecosystem enablement” when there are so few actually successful ecosystem partners involved beyond antimalware is disingenuous…or at best, a hopeful prediction of some future state.

Here’s something I wrote on the topic back in 2009: The Cart Before the Virtual Horse: VMware’s vShield/Zones vs. VMsafe APIs that I think illustrates some of the issues related to the perceived “strategy by bumping around in the dark.”

A big point of confusion is that vShield simultaneously describes both an ecosystem program and a set of products that is actually more than just anti-malware capabilities which is where the bulk of integration today is placed.

Analysts and journalists continue to miss the fact that “vShield” is actually made up of 4 components (not counting the VMsafe APIs):

  • vShield Edge
  • vShield App
  • vShield Endpoint
  • vShield Manager

What most people often mean when they refer to “vShield” are the last two components, completely missing the point that the first two products — which are now monetized and marketed/sold as core products for vSphere and vCloud Director — basically make it very difficult for the ecosystem to partner effectively since it’s becoming more difficult to exchange vShield solutions for someone else’s.

An important reason for this is that VMware’s sales force is incentivized (and compensated) on selling VMware security products, not the ecosystem’s — unless of course it is in the way of a big deal that only a partnership can overcome.  This is the interesting juxtaposition of VMware’s “good enough” versus incumbent security vendors “best-of-breed” product positioning.

VMware is not a security or networking company and ignoring the fact that big companies with decades of security and networking products are not simply going to fade away is silly.  This is true of networking as it is security (see software-defined networking as an example.)

Technically, vShield Edge is becoming more and more a critical piece of the overall architecture for VMware’s products — it acts as the perimeter demarcation and multi-tenant boundary in their Cloud offerings and continues to become the technology integration point for acquisitions as well as networking elements such as VXLAN.

As a third party tries to “integrate” a product which is functionally competitive with vShield Edge, the problems start to become much more visible and the partnerships more and more clumsy, especially in the eyes of the most important party privy to this scenario: the customer.

Jon Oltsik wrote a story recently in which he described the state of VMware’s security efforts: “vShield, Cloud Computing, and the Security Industry

So why aren’t more security vendors jumping on the bandwagon? Many of them look at vShield as a potentially competitive security product, not just a set of APIs.

In a recent Network World interview, Allwyn Sequeira, VMware’s chief technology officer of security and vice president of security and network solutions, admitted that the vShield program in many respects “does represent a challenge to the status quo” … (and) vShield does provide its own security services (firewall, application layer controls, etc.)

Why aren’t more vendors on-board? It’s because this positioning of VMware’s own security products which enjoy privileged and unobstructed access to the platform that ISV’s in the ecosystem do not have.  You can’t move beyond the status quo when there’s not a clear plan for doing so and the past and present are littered with the wreckage of prior attempts.

VMware has its own agenda: tightly integrate security services into vSphere and vCloud to continue to advance these platforms. Nevertheless, VMware’s role in virtualization/cloud and its massive market share can’t be ignored. So here’s a compromise I propose:

  1. Security vendors should become active VMware/vShield partners, integrate their security solutions, and work with VMware to continue to bolster cloud security. Since there is plenty of non-VMware business out there, the best heterogeneous platforms will likely win.
  2. VMware must make clear distinctions among APIs, platform planning, and its own security products. For example, if a large VMware shop wants to implement vShield for virtual security services but has already decided on Symantec (Vontu) or McAfee DLP, it should have the option for interoperability with no penalties (i.e., loss of functionality, pricing/support premiums, etc.).

Item #1 Sounds easy enough, right? Except it’s not.  If the way in which the architecture is designed effectively locks out the ecosystem from equal access to the platform except perhaps for a privileged few, “integrating” security solutions in a manner that makes those solutions competitive and not platform-specific is a tall order.  It also limits innovation in the marketplace.

Look how few startups still exist who orbit VMware as a platform.  You can count them on less fingers that exist on a single hand.  As an interesting side-note, Catbird — a company who used to produce their own security enforcement capabilities along with their strong management and compliance suite — has OEM’d VMware’s vShield App product instead of bothering to compete with it.

Now, item #2 above is right on the money.  That’s exactly what should happen; the customer should match his/her requirements against the available options, balance the performance, efficacy, functionality and costs and ultimately be free to choose.  However, as they say in Maine…”you can’t get there from here…” at least not unless item #1 gets solved.

In a complimentary piece to Jon’s, Ellen Messmer writes in “VMware strives to expand security partner ecosystem“:

Along with technical issues, there are political implications to the vShield approach for security vendors with a large installed base of customers as the vShield program asks for considerable investment in time and money to develop what are new types of security products under VMware’s oversight, plus sharing of threat-detection information with vShield Manager in a middleware approach.

…and…

The pressure to make vShield and its APIs a success is on VMware in some respects because VMware’s earlier security API , the VMsafe APIs, weren’t that successful. Sequiera candidly acknowledges that, saying, “we got the APIs wrong the first time,” adding that “the major security vendors have found it hard to integrate with VMsafe.”

Once bitten, twice shy…

So where’s the confidence that guarantees it will be easier this time? Basically, besides anti-malware functionality provided by integration with vShield endpoint, there’s not really a well-defined ecosystem-wide option for integration beyond that with VMware now.  Even VMware’s own roadmaps for integration are confusing.  In the case of vCloud Director, while vShield Edge is available as a bundled (and critical) component, vShield App is not!

Also, forcing integration with security products now to directly integrate with vShield Manager makes for even more challenges.

There are a handful of security products besides anti-malware in the market based on the VMsafe APIs, which are expected to be phased out eventually. VMware is reluctant to pin down an exact date, though some vendors anticipate end of next year.

That’s rather disturbing news for those companies who have invested in the roadmap and certification that VMware has put forth, isn’t it?  I can name at least one such company for whom this is a concern. :(

Because VMware has so far reserved the role of software-based firewalls and data-loss prevention under vShield to its own products, that has also contributed to unease among security vendors. But Sequiera says VMware is in discussions with Cisco on a firewall role in vShield.   And there could be many other changes that could perk vendor interest. VMware insists its vShield APIs are open but in the early days of vShield has taken the approach of working very closely with a few selected vendors.

Firstly, that’s not entirely accurate regarding firewall options. Cisco and Juniper both have VMware-specific “firewalls” on the market for some time; albeit they use different delivery vehicles.  Cisco uses the tightly co-engineered effort with the Nexus 1000v to provide access to their VSG offering and Juniper uses the VMsafe APIs for the vGW (nee’ Altor) firewall.  The issue is now one of VMware’s architecture for integrating moving forward.

Cisco has announced their forthcoming vASA (virtual ASA) product which will work with the existing Cisco VSG atop the Nexus 1000v, but this isn’t something that is “open” to the ecosystem as a whole, either.  To suggest that the existing APIs are “open” is inaccurate and without an API-based capability available to anyone who has the wherewithal to participate, we’ll see more native “integration” in private deals the likes of which we’re already witnessing with the inclusion of RSA’s DLP functionality in vShield/vSphere 5.

Not being able to replace vShield Edge with an ecosystem partner’s “edge” solution is really a problem.

In general, the potential for building a new generation of security products specifically designed for VMware’s virtualization software may be just beginning…

Well, it’s a pretty important step and I’d say that “beginning” still isn’t completely realized!

It’s important to note that these same vendors who have been patiently navigating VMware’s constant changes are also looking to emerging competitive platforms to hedge their bets. Many have already been burned by their experience thus far and see competitive platform offerings from vendors who do not compete with their own security solutions as much more attractive, regardless of how much marketshare they currently enjoy.  This includes community and open source initiatives.

Given their druthers, with a stable, open and well-rounded program, those in the security ecosystem would love to continue to produce top-notch solutions for their customers on what is today the dominant enterprise virtualization and cloud platform, but it’s getting more frustrating and difficult to do so.

It’s even worse at the service provider level where the architectural implications make the enterprise use cases described above look like cake.

It doesn’t have to be this way, however.

Jon finished up his piece by describing how the VMware/ecosystem partnership ought to work in a truly cooperative manner:

This seems like a worthwhile “win-win,” as that old tired business cliche goes. Heck, customers would win too as they already have non-VMware security tools in place. VMware will still sell loads of vShield product and the security industry becomes an active champion instead of a suspicious player in another idiotic industry concept, “coopitition.” The sooner that VMware and the security industry pass the peace pipe around, the better for everyone.

The only thing I disagree with is how this seems to paint the security industry as the obstructionist in this arms race.  It’s more than a peace pipe that’s needed.

Puff, puff, pass…it’s time for more than blowing smoke.

SecurityAutomata: A Reference For Security Automation…

June 24th, 2011 No comments

The SecurityAutomata Project is themed toward enabling consumers, service and technology solution providers to collectively share knowledge on how to automate and focus on the programmability of “security” across physical, virtual and cloud environments.

It’s a bit of an experiment, really. I want to enable better visibility into the state-of-the-art (as it were) of security automation by providing a neutral ground to discuss and demonstrate how security can be automated in physical, virtual and cloud computing environments.

There are many solutions available today but it’s often difficult to grasp how the approaches differ from one another and what sort of capabilities must exist to get them to work.

Please help us organize and contribute content to the SecurityAutomata Wiki here.
