Black:
Probably the largest challenge we all have is maintaining consistent
connectivity. We're now able to keep data locally or make it highly
extensible, whether it’s delivered through the cloud or a virtualized
application. So, it’s a mix and a blend. But from a security lens, each
one of those of service capabilities has a certain nuance that we need
to be cognizant of while we're trying to protect data at rest, in use,
and in motion.Gardner: I've heard you speak about bring your own device (BYOD), and for you, BYOD devices have ended up being more secure than company-provided devices. Why do you think that is?
Caring for assets
Black: Well, if you own the car, you tend to take care of it. When you have a BYOD asset, you tend to take care of it, because ultimately, you're going to own that, whether it’s purchased for you with a retainer or what have you.

Gardner: This also I think points out the importance of behaviors and end-user culture and thinking about security, acting in certain ways. Let's go to you, Craig. How do we get that benefit of behavior and culture as we think more about mobility and security?
Patterson: When we look at mobile, we've had people who would have a mobile device out in the field. They're accustomed to being able to take an email, and that email may have, in our situation, private information -- Social Security numbers, certain client IDs -- on it, things that we really don't want out in the public space. The culture has been, take a picture of the screen and text it to someone else. Now, it’s in another space, and that private information is out there.
You go from working in a home environment, where you text everything back and forth, to having secure information that needs to be containerized, shrink-wrapped, and not go outside a certain control parameter for security. Now, you're having a culture fight [over] utilization. People are accustomed to using their devices in one way and now, they have to learn a different way of using devices with a secure environment and wrapping. That’s what we're running into.
Gardner: We've also heard at the recent Citrix Synergy 2016 in Las Vegas that IT should be able to increasingly say "Yes," that it's an important part of getting to better business productivity.
Dan, how do we get people to behave well in secure terms, but not say "No"? Is there a carrot approach to this?
Kaminsky: Absolutely. At the end of the day, our users are going to go ahead and do stuff they need to get their jobs done. I always laugh when people say, "I can’t believe that person opened a PDF from the Internet." They work in HR. Their job is to open resumes. If they don’t open resumes, they're going to lose their job and be replaced by someone else.
 |
| Kaminsky |
The unusual realization that I had is that all these random partners we're getting have random policies and are storing data. We hear a lot of stuff about the Internet of Things (IoT), but I don't know any toasters that have my Social Security number. I know lots of these DocuSign, HelloSign systems that are storing really sensitive documents.
Maybe the solution, if we want people to implement our security technologies, or at least our security policies, is to pay them. Tell them, "If you actually have attracted our users, follow these policies, and we'll give you this amount of money per day, per user, automatically through our authentication layer." It sounds ridiculous, but you have to look at the status quo. The status quo is on fire, and maybe we can pay people to put out their fires.
Quid pro quo
Gardner: Or perhaps there are other quid pro quos that don't involve money? Chad, you work at a large hospital organization and you mentioned that you're 100 percent digital. How did you encourage people with the carrot to adhere to the right policies in a challenging environment like a hospital?
Wilson: We threw out the carrot-and-stick philosophy and just built a new highway. If you're driving on a two-lane highway, and it's always congested, and you want somebody to get there faster, then build a new highway that can handle the capacity and the security. Build the right on- and off-ramps to it and then cut over.

Gardner: It almost sounds like you're looking at the beginning bowler’s approach, where you put rails up on the gutters, so you can't go too far afield, whether you wish to or not. Whit Baker, tell us a little bit about The Watershed and how you view security behavior. Is it rails on the gutters, carrots or sticks, how does it go?
Baker: I would say rails on the gutters for us. We've completely converted everything to a VDI environment. Whether they're connecting with a laptop, with broadband, or their own home computer or mobile device, that session is completely bifurcated from their own operating system.
So, we're not really worried. Your desktop machine can be completely loaded with malware and whatnot, but when you open that session, you're inside of our system. That's basically how we handle the security. It almost doesn't require the users to be conscious of security.
 |
| Baker |
So, it's a little bit of containerization, giving them some rails that they can bounce off of, and education.
Gardner: Stan, thinking about other ways that we can encourage good security posture in the mobility era, authentication certainly comes to mind, multi-factor authentication (MFA). How does that play into this keeping people safe?
Behavior elements
Black: It’s a mix of how we're going to deliver the services, but it's also a mix of the behavior elements and the fact that now technology has progressed so much that you can provide a user an entire experience that they actually enjoy. It gives them what they need, inside of a secure session, inside of a secure socket layer, with the inability to go outside of those bowling lanes, if they're not authorized to do so.
Additionally, authentication technologies have come a long way from hard tokens that we used to wear. I've seen people with four, five, or six of them, all in one necklace. I think I might have been one of them.
Authentication technologies have come a long way from hard tokens that we used to wear.
Multi-factor authentication and the user interface are all pieces of information that aren't tied to the person's privacy or that individual, like their Social Security Number, but it’s their user experience enabling them to connect seamlessly. Often, when you have a help-desk environment, as an example, you put a time-out on their system. They go from one phone call to another phone call and then they have to log back in.
The interfaces that we have now and the MFA, the simple authentication, the simplified side on all of those, enable a person, depending upon what their role is, to connect into the environment they need to do their job quickly and easily.
Gardner: You mentioned user experience, and maybe that’s the quid pro quo. You get more user experience benefits if you take more precautions with how you behave using your devices.
Dan, any thoughts on where we go with authentication and being able to say, Yes, and encourage people to do the right thing?

You know what VPNs meant? VPNs meant you didn't have to drive into the office on a Sunday. You could be at home and fix the problem, and hours became minutes or seconds. Everything that we do that really works involves making things more useable and enabling people. Security is giving you permission to do this thing that used to be dangerous.
Security is giving you permission to do this thing that used to be dangerous.
I actually have a lot of hope in the mobility space, because a lot of these mobile environments and operating systems are really quite secure. You hand someone an iPad, and in a year, that iPad is still going to work. There are other systems where you hand someone a device and that device is not doing so well a year from now.
So there are a lot more controls and stability from some of these mobile things that people actually like to use more, and they turn out to also be significantly more secure.
Gardner: Craig, as we're also thinking about ways of keeping people on the straight and narrow path, we're getting more intelligent networks. We're starting to get more data and analytics from those devices and we're able to see what goes on in that network in high detail.
Tell us about the ways in which we can segment and then make zones for certain purposes that may come and go based on policies. Basically, how are intelligent networks helping us provide that usability and security?
Access to data
Patterson: The example that comes to my mind is that in many of the industries, we have partners who come on site for a short period of time. They need access to data. They might be doing inspections for us and they'll be going into a private area, but we don't want them to take certain photos, documents and other information off site after a period of time.

| Patterson |
We had kind of an old-fashioned example where people think they are more secure, because they don't know what they're losing. We had people with file cabinets that were locked and they had the key around their neck. They said, "Why should we go to an electronic documents system where I can see when you viewed it, when you downloaded it, where you moved that document to?" That kind of scared some people.
Then, I walked in with half their file cabinet and I said, "You didn’t even know these were gone, but you felt secure the whole time. Wouldn’t you rather know that it was gone and have been able to institute some security protocols behind it?"
A lot of it goes to usability. We want to make things usable and we have to have access to it, but at the same time, those guardrails include not only where we can access it and at what time, but for how long and for what purposes.
Once they go outside of that area, that data is no longer accessible or
they've been logged off the system and they no longer have access to
those documents.
We have mobile devices for which we need to be able to turn the camera functions off in certain parts of our facility. For mobile device management, that's helpful. For BYOD, that becomes a different challenge, and that's when we have to handle giving them a device that we can control, as opposed to BYOD.
Gardner: Stan, another major trend these days is the borderless enterprise. We have supply chains, alliances, ecosystems that provide solutions, an API-first mentality, and that requires us to be able to move outside and allow others to cross over. How does the network-intelligence factor play into making that possible so that we can say, Yes, and get a strong user experience regardless of which company we're actually dealing with?
Black: I agree with the borderless concept. The interesting part of it, though, is with networks knowing where they're connecting to physically. The mobile device has over 20 sensors in it. When you take all of that information and bring it together with whatever APIs are enabled in the applications, you start to have a very interesting set of capabilities that we never had before.
A simple example is, if you're a database administrator and you're administering something inside the European Union (EU), there are very stringent privacy laws that make it so you're not allowed to do that.
We don’t have to make it that we have to train the person or make it more difficult for them; we simply disable the capability through geofencing. When one application is talking securely through a socket, all the way to the back end, from a mobile device, all the way into the data center, you have pretty darn good control. You can also separate duties; system administration being one function, whereas database administration is another very different thing. One set doesn't see the private data; one set has very clear access to it.
Getting visibility
Gardner: Chad, you mentioned how visibility is super important for you and your organization. Tell me a bit about moving beyond the user implications. What about the operators? How do you get that visibility and keep it, and how important is that to maintaining your security posture?
Wilson: If you can't see it, you can’t protect it. No matter how much visibility we get into the back end, if the end user doesn't adopt the application or the virtualization that we've put in place or the highway that we've built, then we're not going to see the end-to-end session. They're going to continue to do workarounds.
So, usability is very important to end-user adoption and adopting the new technologies and the new platforms. Systems have to be easy for them to access and to use. From the back-end, the visibility piece, we look at adopting technology strategically to achieve interoperability, not just point products here and there to bolt them on.
So, instead of thinking about things from a device-to-device-to-device
perspective, we're thinking about one holistic service-delivery
platform, and that's the new highway that provides that visibility.
A strategic innovation and a strategic procurement around technology and partnership, like we have with Citrix, allows us to have a consistent delivery of the application and the end user experience, no matter what device they go to, and where they access from in the world. On the back side, that helps us, because we can have that end-to-end visibility of where our data is heading, the authentication right upfront, as well as all the pieces and parts of the network that go into play to deliver that experience.
So, instead of thinking about things from a device-to-device-to-device perspective, we're thinking about one holistic service-delivery platform, and that's the new highway that provides that visibility.
Gardner: Whit, we've heard a lot about the mentality that you should always assume someone unwanted is in your network. Monitoring and response is one way of limiting that. How does your organization acknowledge that bad things can happen, but that you can limit that, and how important is monitoring and response for you in reducing damage?
Baker: In our case, we have several layers of user experience. Through policy, we only allow certain users to do certain things. We're a healthcare system, but we have various medical personnel; doctors, nurses and therapists, versus people in our corporate billing area and our call center. All of those different roles are basically looking only at the data that they need to be accessing, and through policy, it’s fairly easy to do.
Gardner: Stan, on the same subject, monitoring and response, assuming that people are in, what is Citrix seeing in the field, and how are you giving that response time as low a latency as possible?
Standard protocol
Black: The standard incident-response protocol is identify, contain, control, and communicate. We're able to shrink what we need to identify. We're able to connect from end-to-end, so we're able to communicate effectively, and we've changed how much data we gather regarding transmissions and communications.
If you think about it, we've shrunk our tech surface, we've shrunk our vulnerable areas, methods, or vectors by which people can enter in. At the same time, we've gained incredibly high visibility and fidelity into what is supposed to be going over a wire or wireless, and what is not.
We're now able to shrink the identify, contain, control, and communicate spectrum to a much shorter area and focus our efforts with really smart threat intelligence and incident response people versus everyone in the IT organization and everyone in security. Everyone is looking at the needle in the haystack; now we just have a smaller stack of needles.
Patterson: I had a thought on that, because as we looked at a cloud-first strategy, one of the issues that we looked at was, "We have a voice-over-IP system in the cloud, we have Azure, we have Citrix, we have our NetScaler. What about our firewalls now, and how do we actually monitor intrusion?"
Citrix and Microsoft are helping us with that in our environments, but
those are still open questions for us. We're not entirely satisfied with
the answers yet.
We have file attachments and emails coming through in ways that aren’t on our on-premises firewall and not with all our malware detection. So, those are questions that I think all of us are trying to answer, because now we're creating known unknowns and really unknown unknowns. When it happens, we're going to say, "We didn’t know that that part could happen."
That’s where part of the industry is, too. Citrix and Microsoft are helping us with that in our environments, but those are still open questions for us. We're not entirely satisfied with the answers yet.
Gardner: Dan, one of the other ways that we want to be able to say, Yes, to our users and increase their experiences as workers is to recognize the heterogeneity -- any cloud, any device, multiple browser types, multiple device types. How do you see the ability to say, Yes, to vast heterogeneity, perhaps at a scale we've never seen before, but at the same time, preserve that security and keep those users happy?
Kaminsky: The reason we have different departments and multiple teams is because different groups have different requirements. They have different needs that are satisfied in ways that we don't necessarily understand. It’s not the heterogeneity that bothers us; it’s the fact that a lot of systems have different risks. We can merge the risks, or simultaneously address them with consistent technologies, like containerization and virtualization, like the sort of centralization solutions out there.
People are sometimes afraid of putting all their eggs in one basket. I'll take one really well-built basket over 50,000 totally broken ones. What I see is, create environments in which users can use whatever makes their job work best, and go ahead and realize that it's not actually the fact that the risks are that distinct, that they are that unique. The risk patterns of the underlying software are less diverse than the software itself.
Gardner: Stan, most organizations that we speak to say they have at least six, perhaps more, clouds. They're using all sorts of new devices. Citrix has recently come out with Raspberry Pi at less than a $100 to be a viable Windows 10 endpoint. How do we move forward and keep the options open for any cloud and any device?
Multitude of clouds
Black: When you look at the cloud, there is a multitude of public clouds. Many companies have internal clouds. We've seen all of this hyperconvergence, but what has blurred over time are the controls between whether it’s a cloud, whether it’s the enterprise, and whether it’s mobile.
Again, some of what you've seen has been how certain technologies can fulfill controls between the enterprise and the cloud, because cloud is nimble, it’s fast, and it's great.
At the same time, if you don't control it, don’t manage it, or don't know what you have in the cloud, which many companies struggle with, your risk starts to sprawl and you don't even know it's happened.
So it's not adding difficult controls, what I would call classic gates, but transparency, visibility, and thresholds. You're allowed to do this between here and here. An end user doesn't know those things are happening.
Also, weaving analytics into every connection, knowing what that wire is
supposed to look like, what that packet is supposed to look like gives
you a heck of a lot more control than we've had for decades.
Also, weaving analytics into every connection, knowing what that wire is supposed to look like, what that packet is supposed to look like gives you a heck of a lot more control than we've had for decades.
Gardner: Chad, for you and your organization, how would you like to get security visibility in terms of an analytic dashboard, visualization, and alerts? What would you like to see happen in terms of that analytics benefit?
Wilson: It starts with population health and the concept behind it. Population health takes in all the healthcare data, puts it into a data warehouse, and leverages analytics to be able to show trends with, say, kids presenting with asthma or patients presenting with asthma across their lifespan and other triggers. That goes to quality of care.
The same concept should be applied to security. When we bring that data together, all the various logs, all of the various threat vectors and what we are seeing, not just signatures, but we're able to identify trends, and how folks are doing it, how the bad guys are doing it. Are the bad guys single-vectored or have they learned the concept of combined arms, like our militaries have? Are they able to put things together to have better impact? And where do we need to put things together to have better protection?
We need to change the paradigm, so when they show their hand once, it doesn't work anymore. The only way that we can do that is by being able to detect that one time when they show their hand. It's getting them to do one thing to show how they are going to attack us. To do that, we have to pull together all the logs, all of the data, and provide analytics and get down to behavior; what is good behavior, what is bad behavior.
That's not a signature that you're detecting for malware; that is a behavior pattern. Today I can do one thing, and tomorrow I can do it differently. That's what we need to be able to get to.
Getting information
Patterson: I like the illustration that was just used. What we're hoping for with the cloud strategy is that, when there's an attack on one part of the cloud, even if it's someone else that’s in Citrix or another cloud provider, then that is shared, whereas before we have had all these silos that need to be independently secured.
Now, the windows that are open in these clouds that we're sharing are going to be ways that we can protect each one from the other. So, when one person attacks Citrix a certain way, Azure a certain way, or AWS a certain way, we can collectively close those windows.
I want to know where the windows are open and where the heat loss went or where there was air intrusion.
What I like to see in terms of analytics is, and I'll use kind of a mechanical engineering approach, I want to know where the windows are open and where the heat loss went or where there was air intrusion. I would like to see, whether it went to an endpoint that wasn't secured or that I didn't know about. I'd like to know more about what I don't know in my analytics. That’s really what I want analytics for, because the things that I know I know well, but I want my analytics to tell me what I don't know yet.
Gardner: I'm afraid we will have to leave it there. You've been listening to a BriefingsDirect discussion focused on the heightened role of security in the age of global cloud and mobile delivery of apps and data.
We've heard how security concerns increasingly dwarf other architecture considerations, particularly when we take into consideration behavior and the ability to provide a strong and beneficial user experience.
We've learned how the advances in thin clients, desktop virtualization, cloud management services, and mobile-delivery networks are allowing for both increased security and edge apps performance gains.
