Yes…. it has been a while since I posted on this blog, but I’m still alive ;-)

For a 2016 starter (what?!? is it June already), I want to ramble on about information security in the digital workspace. With a growing number of digital workspace transformations going on, information security is more important than ever. With the growing variety of client endpoints and methodes of access in the personal and corporate environments, users are becoming increasingly independent from the physical company locations. Making it interesting how to centrally manage storage of data, passwords, access policies, application settings and network access (just examples, not the complete list). For any place, any device, any information and any application environments for your users (or do we want any user in there), it is not just a couple of clicks of this super-duper secure solution and were done.

Storing data on for example Virtual Desktop servers (hello VMware Horizon!) in the data center is (hopefully) a bit more secure than storing it locally on the user’s endpoint. At the same time, allowing users to access virtual desktops remotely puts your network at a higher risk then local only. But it’s not all virtual desktops. We have mobile users who will like to have the presentations or the applications directly on the tablet or handheld. I for instance, don’t want to have to open a whole virtual desktop for just one application. You ever tried a virtual desktop on a iPhone, it is technical possible yes, but works crappy. Erm forgot my Macbook HDMI USB-C converter for this presentation, well I send it to your gmail or dropbox for access with the native mobile apps at your conference room. And the information is gone out of the company sphere…..(a hypothetical situation of course..)

Data Leak

Great ideas all those ways to be in and out of company information. But but but….. these also pose some challenges to which a lot of companies have not started thinking about. Sounds a bit foolish as it is probably the biggest asset of a company, information. But unfortunately it’s a fact (or maybe it could be just the companies I visit). Sure these companies have IT departments or IT vendors who think a bit about security. And in effect mostly make their users life’s miserable with all sort of technical barriers installed in the infrastructure. In which the users, business and IT (!) users, will find all sorts of ways to pass these installed barriers. Why? First of all to increase their productivity while effectively decreasing security, and secondly they are not informed about the important why. And then those barriers can be just a nuisance.

IT’s Business

I have covered this earlier in my post (https://pascalswereld.nl/2015/03/31/design-for-failure-but-what-about-the-failure-in-designs-in-the-big-bad-world). The business needs to have full knowledge of their required processes and information flows, that support or process in and out information for the services supporting the business strategy. And the persons that are part of the business and operate the services. And what to do with this information in what different ways, is it allowed for certain users to access the information outside of the data center and such. Compliancy to for example certain local privacy laws. Governance with policies and choices, and risk management do we do this part or not, how do we mitigate some risk if we take approach y, and what are the consequences if we do (or don’t).

Commitment from the business and people in the business is of utmost importance for information security. Start explaining, start educating and start listening.
If scratch is the starting point, start the writing first on a global level. What does the business mean by working from everywhere everyplace, what is this digital workspace and such.  What are the risks, how do we approach IAM, what do we have for data loss protection (DLP), is it allowed for IT to inspect SSL traffic (decrypt, inspect and encrypt) etc. etc.
Not to detailed at first it is not necessary, as it can take a long time to have a version 1.0. We can work on it. And to be fair information security and digital workspace for a fact, is continue evolving and moving. A continual improvement of these processes must be in place. Be sure to check with legal if there are no loops in what has been written in the first iteration.
Then map to logical components (think from the information, why is it there, where does it come from and where does it go, and think for the apps, the users) and then when you have defined the logical components. IT can then add the physical components (insert the providers, vendors, building blocks). Evaluate together, what works, what doesn’t, what’s needed and what is not. And rave and repeat…..

Furthermore, a target for a 100% safe environment all the time will just not cut it. Mission Impossible. Think about and define how to react to information leaks and minimize the surface of a compromise.

Design Considerations

With the above we should have a good starting point for the business requirement phase of a design and deploy of the digital workspace. And there will also be information from IT flowing back to the business for continual improvement.

Within the design of an EUC environment we have several software components were we can take actions to increase (or decrease, but I will leave that part out ;-)) security in the layers of the digital workspace environment. And yes, when software defined is not a option there is always hardware…
And from the previous phase we have some idea what choices can be made in technical ways to conform to the business strategy and policies.

If we think of the VMware portfolio and the technical software layers were we need to think about security, we can go from AirWatch/Workspace ONE, Access Point, Identity Manager, Security Server, Horizon, AppVolumes to User Environment Management. And And….Two-Factor, One Time Password (OTP), Microsoft Security Compliance Manager (SCM) for Windows based components, anti-virus and anti-malware, networking segmentation and access policies with SDDC NSX for Horizon. And what about Business Continuity and disaster recovery plans, and SRM, vDP.
Enterprise Management with vROPS and Log Insight integration to for example SIEM. vRealize for automating and orchestrating to mitigate work arounds or faults in manual steps. And so on and so on. We have all sorts of layers where to implement or help with implementing security and access policies. And how will all these interact? A lot to think about. (It could be that a new blog post series subject is born…)

But the justification should start at the business… Start explaining and start acting! This is probably 80% of the success rate of implementing information security. And the technical components can be made fit, but… after the strategy, policies, information architecture are somewhat clear….

And the people in the business are supporting the need for information security in the workspace. (Am I repeating myself a bit ;-)

Ideas, suggestions, conversation, opinions. Love to hear them.
