How to Secure Healthcare Files in 2019

In modern health care, there are many reasons for very large files to be stored and sent from person to person. A growing trend is centrally located diagnostic specialists serving multiple clinics. This means image files must be moved from place to place with increasing frequency. These files must be moved and stored securely.

Fortunately for health care IT pros, there are:

  • Regulations to provide minimum expectations of what "secure" means

  • Models from other industries on techniques and technologies for protecting very large files

The road to protection starts with the security devices in place for the network.

The filtering layer

Like in every other industry, you start with standard security devices and practices. However, in healthcare an additional layer is necessary, a layer that examines file types and allows or disallows transit based on explicit permissions attached to user credentials. This additional layer of security is a filter that stops files rather than try to stop accounts. It can protect files based on:

  • Type

  • Contents (looking for certain patterns of information, such as digits arranged the way they are in credit-card numbers)

  • Allowable origination or destination addresses

Where care must be taken, though, is in the file sizes these filters can screen out and block.

The large file problem

Some security devices, especially those that guard the perimeter by looking at the contents of entire files, are limited in just how large a file they can inspect and protect. When looking at new systems, make sure to ask very pointed questions to ensure the filtering capabilities of the system you choose will adequately filter out the files you want blocked.

The VDI solution

There is another approach that some organizations have adopted, one that doesn't require moving files from system to system. A virtual desktop infrastructure (VDI) moves display information, but not files. Sensitive files are left on a single server, where they are easier to protect.

In a VDI scenario, the hardware emphasis shifts from additional layers of perimeter protection to server capabilities and capacities.

Critical server components

Two critical components of the server for these huge files displayed on VDI are the storage and the display adapter.

  1. The storage subsystem will be designed like that of an online analytics processor system, optimized for rapid reads and large data transfers.

  2. The display subsystem must be able to render large files with high resolution and great speed. (This will need to be matched on the workstation end by a graphics adapter that can render the virtual desktop display containing the file at equal resolution.)

Large files can be protected if all standard network and server security protocols are observed, and content filtering is added as a layer of system protection. Health care organizations also should look seriously at VDI for the benefits that come with not moving large files at all. Leaving these files behind inside a secure perimeter can be very comforting when hackers strike. Current Technologies has helped many healthcare organizations across Illinois and the Midwest find and implement the best solution for their business, and can do the same for yours!

Servers Designed For The Real World

Extreme conditions call for extreme servers


When most people think about servers and the rooms in which they live, they think of serious air-conditioning, dust-less raised floors, and row after row of pleasantly blinking lights to let everyone know that all is well. Sometimes in the real world of IT, the world where the data and applications actually live, there are no clean floors or carefully controlled temperatures.

A new generation of servers designed for the real world is emerging. With some tweaks, you can make the most adverse conditions tolerable for your hardware. So how do you deploy servers in those situations and have the confidence that they’ll be reliable for months or years on end?

1. Room To Breathe

The first parameter to consider is temperature. It is remarkable how many servers manage to function in small, unventilated closets with no real airflow and an in-closet temperature that would be reasonable in a sauna. 

Modern blade servers tend to be designed around convection cooling as well as fan-enhanced forced air. If you know that a server will be deployed in extreme conditions, don’t stuff it full of processors or storage boards. Allow the air to flow unimpeded between the components. Modern servers are capable of keeping themselves cool as long as internally air is allowed to flow.

2. Rack Space

Give some thought to how components are stacked in the rack, as well. In many cases, storage is placed at the bottom of the rack because it’s heavy and the stability is good. In extreme conditions, it can be worth looking for secondary sources of stability — bolting the rack to the floor wall — while the heat-generating spinning disks are situated above the processor units.

With careful rack construction, physics can work in your favor with convection currents adding to the airflow and heat dissipation.

3. Stop The Spinning

Another consideration is whether it might be possible to eliminate spinning disk storage altogether and replace it with solid state drives. This is one of the tradeoffs that will involve thinking about:

  1. The data that will be generated and used on site

  2. The budget for the system

  3. Whether network connectivity is available to make cloud or central storage a realistic possibility

4. And The Rest

Other considerations will include networking, backup, and connectivity for any on-site instrumentation that will be part of the deployment. With everything that is connected to the system, look for jacketed connectors and ask your vendor about rack fan units that can keep air moving in the warmest situations.

One more thing: monitor the environment. There are a number of possibilities for environmental monitoring and reporting, possibilities that range from those that are standard in blade server frames to separate temp/humidity/vibration reporting units. Current Technologies has been designing hardware networking and storage racks for 20+ years. Our experienced and knowledgeable team can deliver you a set up that will survive any conditions long into the future

After designing the server and rack properly, then keep an eye on the conditions inside the rack. There’s no reason why your server can’t survive in the most demanding circumstances.
