As smartphones have become de rigueur in the global digital economy, users want them to do more work, and businesses want them to be more productive for their employees -- as well as powerful added channels to consumers.
But neither businesses nor mobile-service providers have a cross-domain architecture that supports all the new requirements for a secure digital economy, one that allows safe commerce, data sharing and user privacy.
So how do we blaze a better path to a secure mobile future? How do we make today’s ubiquitous mobile devices as low risk as they are indispensable?
BriefingsDirect recently posed these and other questions to a panel of experts on mobile security: Paul Madsen, Principal Technical Architect in the Office of the CTO at Ping Identity; Michael Barrett, President of the FIDO (Fast Identity Online) Alliance, and Mark Diodati, a Technical Director in the Office of the CTO at Ping Identity. The sponsored panel discussion is moderated by me, Dana Gardner, Principal Analyst at Interarbor Solutions.
Here are some excerpts:
Gardner: We're approaching this Cloud Identity Summit 2014 (CIS) in Monterey, Calif. on July 19 and we still find that the digital economy is not really reaching its full potential. We're still dealing with ongoing challenges for trust, security, and governance across mobile devices and network.
Even though people have been using mobile devices for decades—and in some markets around the world they're the primary tool for accessing the Internet—why are we still having problems? Why is this so difficult to solve?
Diodati: There are so many puzzle pieces to make the digital economy fully efficient. A couple of challenges come to mind. One is the distribution of identity. In prior years, the enterprise did a decent job -- not an amazing job, but a decent job -- of identifying users, authenticating them, and figuring out what they have access to.
Once you move out into a broader digital economy, you start talking about off-premises architectures and the expansion of user constituencies. There is a close relationship with your partners, employees, and your contractors. But relationships can be more distant, like with your customers.
Mobility can do a couple of things for us. In the old days, if you want more identity assurance to access important applications, you pay more in cost and usability problems. Specialized hardware was used to raise assurance. Now, the smartphone is really just a portable biometric device that users carry without us asking them to do so. We can raise assurance levels without the draconian increase in cost and usability problems.
We’re not out of the woods yet. One of the challenges is nailing down the basic administrative processes to bind user identities to mobile devices. That challenge is part cultural and part technology. [See more on a new vision for identity.]
Gardner: So it seems that we have a larger set of variables, end users, are not captive on network, who we authenticate. As you mentioned, the mobile device, the smartphone, can be biometric and can be an even better authenticator than we've had in the past. We might actually be in a better position in a couple of years. Is there a transition that’s now afoot that we might actually come out better on the other end?
Madsen: The opportunities are clear. As Mark indicated, the phones, not just because of its technical features, but because of the relatively tight binding that users feel for them, make a really strong authentication factor.
It's the old trope of something you have, something you know, and something you are. Phones are something you already have, from the user’s point of view. It’s not an additional hard token or hard USB token that we're asking employees to carry with them. It's something they want to carry, particularly if it's a BYOD phone.
So phones, because they're connected mobile computers, make a really strong second-factor authentication, and we're seeing that more and more. As I said, it’s one that users are happy using because of the relationship they already have with their phones, for all the other reasons. [See more on identity standards and APIs.]
Gardner: It certainly seems to make sense that you would authenticate into your work environment through your phone. You might authenticate in the airport to check in with your phone and you might use it for other sorts of commerce. It seems that we have the idea, but we need to get there somehow.
What’s architecturally missing for us to make this transition of the phone as the primary way in which people are identified session by session, place by place? Michael, any thoughts about that?
Barrett: There are a couple of things. One, in today’s world, we don’t yet have open standards that help to drive cross-platform authentication, and we don’t have the right architecture for that. In today’s world still, if you are using a phone with a virtual keyboard, you're forced to type this dreadful, unreadable tiny password on the keyboard, and by the way, you can’t actually read what you just typed. That’s a pretty miserable user experience, which we alluded to earlier.
But also, it’s a very ugly. It’s a mainframe-centric architecture. The notion that the authentication credentials are shared secrets that you know and that are stored on some central server is a very, very 1960s approach to the world. My own belief is that, in fact, we have to move towards a much more device-centric authentication model, where the remote server actually doesn’t know your authentication credentials. Again, that comes back to both architecture and standards.
My own view is that if we put those in place, the world will change. Many of us remember the happy days of the late '80s and early '90s when offices were getting wired up, and we had client-server applications everywhere. Then, HTML and HTTP came along, and the world changed. We're looking at the same kind of change, driven by the right set of appropriately designed open standards.
Gardner: So standards, behavior, and technology make for an interesting adoption path, sometimes a chicken and the egg relationship. Tell me about FIDO and perhaps any thoughts about how we make this transition and adoption happen sooner rather than later?
Barrett: I gave a little hint. FIDO is an open-standards organization really aiming to develop a set of technical standards to enable device-centric authentication that is easier for end users to use. As an ex-CTO, I can tell you the experience when you try to give them stronger authenticators that are harder for them to use. They won’t voluntarily use them.
We have to do better than we're doing today in terms of ease of use of authentication. We also have to come up with authentication that is stronger for the relying parties, because that’s the other face of this particular coin. In today’s world, passwords and pins work very badly for end users. They actually work brilliantly for the criminals.
So I'm kind of old school on this. I tend to think that security controls should be there to make life better for relying parties and users and not for criminals. Unfortunately, in today’s world, they're kind of inverted.
So FIDO is simply an open-standards organization that is building and defining those classes of standards and, through our member companies, is promulgating deployment of those standards.
Madsen: I think FIDO is important. Beyond the fact that it’s a standard is the pattern that it’s normalizing. The pattern is one where the user logically authenticates to their phone, whether it be with a fingerprint or a pin, but the authentication is local. Then, leveraging the phone’s capabilities -- storage, crypto, connectivity. etc. -- the phone authenticates to the server. It’s that pattern of a local authentication followed by a server authentication that I think we are going to see over and over.
Gardner: Thank you, Paul. It seems to me that most people are onboard with this. I know that, as a user, I'm happy to have the device authenticate. I think developers would love to have this authentication move to a context on a network or with other variables brought to bear. They can create whole new richer services when they have a context for participation. It seems to me the enterprises are onboard too. So there's a lot of potential momentum around this. What does it take now to move the needle forward? What should we expect to hear at CIS?
Diodati: There are two dimensions to moving the needle forward: avoiding the failures of prior mobile authentication systems, and ensuring that modern authentication systems support critical applications. Both are crucial to the success of any authentication system, including FIDO.
At CIS, we have an in-depth, three-hour FIDO workshop and many mobile authentication sessions.
There are a couple of things that I like about FIDO. First, it can use the biometric capabilities of the device. Many smart phones have an accelerometer, a camera, and a microphone. We can get a really good initial authentication. Also, FIDO leverages public-key technology, which overcomes some of the concerns we have around other kinds of technologies, particularly one-time passwords.
Madsen: To that last point Mark, I think FIDO and SAML, or more recent federation protocols, complement each other wonderfully. FIDO is a great authentication technology, and federation historically has not resolved that. Federation didn't claim to answer that issue, but if you put the two together, you get a very strong initial authentication. Then, you're able to broadcast that out to the applications that you want to access. And that’s a strong combination.
Barrett: One of the things that we haven't really mentioned here -- and Paul just hinted at it -- is the relationship between single sign-on and authentication. When you talk to many organizations, they look at that as two different sides of the same coin. So the better application or ubiquity you can get, and the more applications you can sign the user on with less interaction, is a good thing.
Gardner: Before we go a little bit deeper into what’s coming up, let’s take another pause and look back. There have been some attempts to solve these problems. Many, I suppose, have been from a perspective of a particular vendor or a type of device or platform or, in an enterprise sense, using what they already know or have.
We've had containerization and virtualization on the mobile tier. It is, in a sense, going back to the past where you go right to the server and very little is done on the device other than the connection. App wrapping would fall under that as well, I suppose. What have been the pros and cons and why isn’t containerization enough to solve this problem? Let’s start with Michael.
Barrett: If you look back historically, what we've tended to see are lot of attempts that are truly proprietary in nature. Again, my own philosophy on this is that proprietary technology is really great for many things, but there are certain domains that simply need a strong standards-based backplane.
There really hasn't been an attempt at this for some years. Pretty much, we have to go back to X.509 to see the last major standards-based push at solving authentication. But X.509 came with a whole bunch of baggage, as well as architectural assumptions around a very disconnected world view that is kind of antithetical to where we are today, where we have a very largely connected world view.
I tend to think of it through that particular set of lenses, which is that the standards attempts in this area are old, and many of the approaches that have been tried over the last decade have been proprietary.
For example, on my old team at PayPal, I had a small group of folks who surveyed security vendors. I remember asking them to tell me how many authentication vendors there were and to plot that for me by year?
Growing number of vendors
They sighed heavily, because their database wasn’t organized that way, but then came back a couple of weeks later. Essentially they said that in 2007, it was 30-odd vendors, and it has been going up by about a dozen a year, plus or minus some, ever since, and we're now comfortably at more than 100.
Any market that has 100 vendors, none of whose products interoperate with each other, is a failing market, because none of those vendors, bar only a couple, can claim very large market share. This is just a market where we haven’t seen the right kind of approaches deployed, and as a result, we're struck where we are today without doing something different.
Gardner: Paul, any thoughts on containerization, pros and cons?
Madsen: I think of phones as almost two completely orthogonal aspects. First is how you can leverage the phone to authenticate the user. Whether it’s FIDO or something proprietary, there's value in that.
Secondly is the phone as an application platform, a means to access potentially sensitive applications. What mobile applications introduce that’s somewhat novel is the idea of pulling down that sensitive business data to the device, where it can be more easily lost or stolen, given the mobility and the size of those devices.
The challenge for the enterprise is, if you want to enable your employees with devices, or enable them to bring their own in, how do you protect that data. It seems more and more important, or recognized as the challenge, that you can’t.
The challenge is not only protecting the data, but keeping the usage of the phone separate. IT, arguably and justifiably, wants to protect the business data on it, but the employee, particularly in a BYOD case, wants to keep their use of the phone isolated and private.
So containerization or dual-persona systems attempt to slice and dice the phone up into two or more pieces. What is missing from those models, and it’s changing, is a recognition that, by definition, that’s an identity problem. You have two identities—the business user and the personal user—who want to use the same device, and you want to compartmentalize those two identities, for both security and privacy reasons.
Identity standards and technologies could play a real role in keeping those pieces separate.The employee might use Box for the business usage, but might also use it for personal usage. That’s an identity problem, and identity will keep those two applications and their usages separate.
Diodati: To build on that a little bit, if you take a look at the history of containerization, there were some technical problems and some usability problems. There was a lack of usability that drove an acceptance problem within a lot of enterprises. That’s changing over time.
To talk about what Michael was talking about in terms of the failure of other standardized approaches to authentication, you could look back at OATH, which is maybe the last big industry push, 2004-2005, to try to come up with a standard approach, and it failed on interoperability. OATH was a one-time password, multi-vendor capability. But in the end, you really couldn’t mix and match devices. Interoperability is going to be a big, big criteria for acceptance of FIDO. [See more on identity standards and APIs.]
Mobile device management
Gardner: Another thing out there in the market now, and it has gotten quite a bit of attention from enterprises as they are trying to work through this, is mobile device management (MDM). Do you have any thoughts, Mark, on why that has not necessarily worked out or won’t work out? What are the pros and cons of MDM?
Diodati: Most organizations of a certain size are going to need an enterprise mobility management solution. There is a whole lot that happens behind the scenes in terms of binding the user's identity, perhaps putting a certificate on the phone.
Michael talked about X.509. That appears to be the lowest common denominator for authentication from a mobile device today, but that can change over time. We need ways to be able to authenticate users, perhaps issue them certificates on the phone, so that we can do things like IPSec.
Also, we may be required to give some users access to offline secured data. That’s a combination of apps and enterprise mobility management (EMM) technology. In a lot of cases, there's an EMM gateway that can really help with giving offline secure access to things that might be stored on network file shares or in SharePoint, for example.
If there's been a stumbling block with EMM, it's just been that the heterogeneity of the devices, making it a challenge to implement a common set of policies.
But also the technology of EMM had to mature. We went from BlackBerry Enterprise Server, which did a pretty good job in a homogeneous world, but maybe didn't address everybody’s needs. The AirWatchs and the Mobile Irons of the world, they've had to deal with heterogeneity and increased functionality.
Madsen: The fundamental issue with MDM is, as the name suggests, that you're trying to manage the device, as opposed to applications or data on the device. That worked okay when the enterprise was providing employees with their BlackBerry, but it's hard to reconcile in the BYOD world, where users are bringing in their own iPhones or Androids. In their mind, they have a completely justified right to use that phone for personal applications and usage.
So some of the mechanisms of MDM remain relevant, being able to wipe data off the phone, for example, but the device is no longer the appropriate granularity. It's some portion of the device that the enterprise is authoritative over.
Gardner: It seems to me, though, that we keep coming back to several key concepts: authentication and identity, and then, of course, a standardization approach that ameliorates those interoperability and heterogeneity issues. [See more on a new vision for identity.]
So let’s look at identity and authentication. Some people make them interchangeable. How should we best understand them as being distinct? What’s the relationship between them and why are they so essential for us to move to a new architecture for solving these issues? Let’s start with you, Michael.
Identity is center
Barrett: I was thinking about this earlier. I remember having some arguments with Phil Becker back in the early 2000s when I was running the Liberty Alliance, which was the standards organization that came up with SAML 2.0. Phil coined that phrase, "Identity is center," and he used to argue that essentially everything fell under identity.
What I thought back then, and still largely do, is that identity is a broad and complex domain. In a sense, as we've let it grow today, they're not the same thing. Authentication is definitely a sub-domain of security, along with a whole number of others. We talked about containerization earlier, which is a kind of security-isolation technique in many regards. But I am not sure that identity and authentication are exactly in the same dimension.
In fact, the way I would describe it is that if we talk about something like the levels-of-assurance model, we're all fairly familiar with in the identity sense. Today, if you look at that, that’s got authentication and identity verification concepts bound together.
In fact, I suspect that in the coming year or two, we're probably going to have to decouple those and say that it’s not really a linear one-dimensonal thing, with level one, level two, level three, and level four. Rather it's a kind of two-dimensional metric, where we have identity verification concepts on one side and then authentication comes from the other. Today, we've collapsed them together, and I am not sure we have actually done anybody any favors by doing that.
Definitely, they're closely related. You can look at some of the difficulties that we've had with identity over the last decade and say that it’s because we actually ignored the authentication aspect. But I'm not sure they're the same thing intrinsically.
Gardner: Interesting. I've heard people say that any high-level security mobile device has to be about identity. How else could it possibly work? Authentication has to be part of that, but identity seems to be getting more traction in terms of a way to solve these issues across all other variables and to be able to adjust accordingly over time and even automate by a policy.
Mark, how do you see identity and authentication? How important is identity as a new vision for solving these problems?
Diodati: You would have to put security at the top, and identity would be a subset of things that happen within security. Identity includes authorization -- determining if the user is authorized to access the data. It also includes provisioning. How do we manipulate user identities within critical systems -- there is never one big identity in the sky. Identity includes authentication and a couple of other things.
To answer the second part of your question, Dana, in the role of identity and trying to solve these problems, we in the identity community have missed some opportunities in the past to talk about identity as the great enabler.
With mobile devices, we want to have the ability to enforce basic security controls , but it’s really about identity. Identity can enable so many great things to happen, not only just for enterprises, but within the digital economy at large. There's a lot of opportunity if we can orient identity as an enabler.
Authentication and identity
Madsen: I just think authentication is something we have to do to get to identity. If there were no bad people in the world and if people didn’t lie, we wouldn’t need authentication.
We would all have a single identifier, we would present ourselves, and nobody else would lay claim to that identifier. There would be no need for strong authentication. But we don’t live there. Identity is fundamental, and authentication is how we lay claim to a particular identity.
Diodati: You can build the world's best authorization policies. But they are completely worthless, unless you've done the authentication right, because you have zero confidence that the users are who they say there are.
Gardner: So, I assume that multifactor authentication also is in the subset. It’s just a way of doing it better or more broadly, and more variables and devices that can be brought to bear. Is that correct?
Diodati: The definition of multifactor has evolved over time too. In the past, we talked about “strong authentication”. What we mean was “two-factor authentication,” and that is really changing, particularly when you look at some of the emerging technologies like FIDO.
If you have to look at the broader trends around adaptive authentication, the relationship to the user or the consumer is more distant. We have to apply a set of adaptive techniques to get better identity assurance about the user.
Gardner: I'm just going to make a broad assumption here that the authentication part of this does get solved, that multifactor authentication, adaptive, using devices that people are familiar with, that they are comfortable doing, even continuing to use many of the passwords, single sign-on, all that gets somehow rationalized.
Then, we're elevated to this notion of identity. How do we then manage that identity across these domains? Is there a central repository? Is there a federation? How would a standard come to bear on that major problem of the federation issue, control, and management and updating and so forth? Let’s go back to Michael on that.
Barrett: I tend to start from a couple of different perspectives on this. One is that we do have to fix the authentication standards problem, and that's essentially what FIDO is trying to do.
So, if you accept that FIDO solves authentication, what you are left with is an evolution of a set of standards that, over the last dozen years or so, starting with SAML 2.0, but then going on up through the more recent things like OpenID Connect and OAuth 2.0, and so on, gives you a robust backplane for building whatever business arrangement is appropriate, given the problem you are trying to solve.
I chose the word "business" quite consciously in there, because it’s fair to say that there are certain classes of models that have stalled out commercially for a whole bunch of reasons, particularly around the dreaded L-word, i.e, liability.
We tried to build things that were too complicated. We could just describe this grand long-term vision of what the universe looked like. Andrew Nash is very fond of saying that we can describe this rich ecosystem as identity-enabled services and so on, but you can’t get there from here, which is the punch line of a rather old joke.
Gardner: Mark, we understand that identity is taking on a whole new level of importance. Are there some examples that we can look to that illustrate how an identity-centric approach to security, governance, manageability for mobile tier activities, even ways it can help developers bring new application programming interfaces (APIs) into play and context for commerce and location, are things we haven’t even scratched the surface of yet really?
Help me understand, through an example rather than telling, how identity fits into this and what we might expect identity to do if all these things can be managed, standards, and so forth.
Diodati: Identity is pretty broad when you take a look at the different disciplines that might be at play. Let’s see if we can pick out a few.
We have spoken about authentication a lot. Emerging standards like FIDO are important, so that we can support applications that require higher assurance levels with less cost and usability problems.
A difficult trend to ignore is the API-first development modality. We're talking about things like OAuth and OpenID Connect. Both of those are very important, critical standards when we start talking about the use of API- and even non-API HTTP based stuff.
OpenID Connect, in particular, gives us some abilities for users to find where they want to authenticate and give them access to the data they need. The challenge is that the mobile app is interacting on behalf of a user. How do you actually apply things like adaptive techniques to an API session to raise identity assurance levels? Given that OpenID Connect was just ratified earlier this year, we're still in early stages of how that’s going to play out.
Gardner: Michael, any thoughts on examples, use cases, a vision for how this should work in the not too distant future?
Barrett: I'm a great believer in open standards, as I think I have shown throughout the course of this discussion. I think that OpenID Connect, in particular, and the fact that we now have that standard ratified, [is useful]. I do believe that the standards, to a very large extent, allow the creation of deployments that will address those use-cases that have been really quite difficult [without these standards in place].
Ahead of demand
The problem that you want to avoid, of course, is that you don’t want a standard to show up too far ahead of the demand. Otherwise, what you wind up with is just some interesting specification that never gets implemented, and nobody ever bothers deploying any of the implementations of it.
So, I believe in just-in-time standards development. As an industry, identity has matured a lot over the last dozen years. When SAML 2.0 came along in Shibboleth, it was a very federation-centric world, addressing a very small class of use cases. Now, we have a more robust sets of standards. What’s going to be really interesting is to see, how those new standards get used to address use cases that the previous standards really couldn’t?
I'm a bit of a believer in sort of Darwinian evolution on this stuff and that, in fact, it’s hard to predict the future now. Niels Bohr famously said, "Prediction is hard, especially when it involves the future.” There is a great deal of truth to that.
Gardner: Hopefully we will get some clear insights at the Cloud Identity Summit this month, July 19, and there will be more information to be had there.
I also wonder whether we're almost past the point now when we talk about mobile security, cloud security, data-center security. Are we going to get past that, or is this going to become more of a fabric of security that the standards help to define and then the implementations make concrete? Before we sign off, Mark, any last thoughts about moving beyond segments of security into a more pervasive concept of security?
Diodati: We're already starting to see that, where people are moving towards software as a service (SaaS) and moving away from on-premises applications. Why? A couple of reasons. The revenue and expense model lines up really well with what they are doing, they pay as they grow. There's not a big bang of initial investment. Also, SaaS is turnkey, which means that much of the security lifting is done by the vendor.
That's also certainly true with infrastructure as a service (IaaS). If you look at things like Amazon Web Services (AWS). It is more complicated than SaaS, it is a way to converge security functions within the cloud.

DevOps tends to focus on the relationship between Dev and Ops, putting an emphasis on the ops and application infrastructure. But that’s changing with microservices architectures. In her session at DevOps Summit, Lori MacVittie, Evangelist for F5 Networks, will focus on how microservices are changing the underlying architectures needed to scale, secure and deliver applications based on highly distributed (micro) services and why that means an expansion into “the network” for DevOps.

Sharding has become a popular means of achieving scalability in application architectures in which read/write data separation is not only possible, but desirable to achieve new heights of concurrency. The premise is that by splitting up read and write duties, it is possible to get better overall performance at the cost of a slight delay in consistency. That is, it takes a bit of time to replicate changes initiated by a "write" to the read-only master database. It's eventually consistent, and it'...

Many people recognize DevOps as an enormous benefit – faster application deployment, automated toolchains, support of more granular updates, better cooperation across groups. However, less appreciated is the journey enterprise IT groups need to make to achieve this outcome. The plain fact is that established IT processes reflect a very different set of goals: stability, infrequent change, hands-on administration, and alignment with ITIL. So how does an enterprise IT organization implement change...

Containers and Docker are all the rage these days. In fact, containers — with Docker as the leading container implementation — have changed how we deploy systems, especially those comprised of microservices. Despite all the buzz, however, Docker and other containers are still relatively new and not yet mainstream. That being said, even early Docker adopters need a good monitoring tool, so last month we added Docker monitoring to SPM. We built it on top of spm-agent – the extensible framework f...

There's a lot of things we do to improve the performance of web and mobile applications. We use caching. We use compression. We offload security (SSL and TLS) to a proxy with greater compute capacity. We apply image optimization and minification to content. We do all that because performance is king.

The causality question behind Conway’s Law is less about how changing software organizations can lead to better software, but rather how companies can best leverage changing technology in order to transform their organizations. Hints at how to answer this question surprisingly come from the world of devops – surprising because the focus of devops is ostensibly on building and deploying better software more quickly. Be that as it may, there’s no question that technology change is a primary fac...
