The security risks of black box technology


By ​Helge Skov Diernæs, Management Consultant at NNIT​

When did you last evaluate the security of your Wi-Fi or Bluetooth-enabled camera or refrigerator?

Simple user interfaces have brought back the black box. Users need only to consider “input” and “output”, so a basic understanding of the technology behind is no longer required.

Users expect new systems and technologies to be created and available quickly. This often results in a strong development focus on user requirements in terms of functionality, performance and reliability, and less so on the security risks involved.

But the security risks often reside inside the black box and these are easily overlooked or ignored. Every new day brings stories about ransom ware and espionage, which remind us about the importance of security housekeeping.

We often see that the key to manage the information security risk of new technologies successfully is to make the risk assessment a mandatory part of the pre-analysis. Before technology acquisition is decided, information security risks can be identified and the costs of mitigations factored in as part of the decision base.

An information security risk assessment of a black box solution is typically carried out by breaking the solution down into its component parts and analyzing each of these individually. This is done by analyzing the hardware, software and application architecture, and will often call on a range of subject matter experts.

By making management approval of the technology acquisition dependent on the outcome of the information security risk assessment, risk implications are kept transparent and the cost of associated mitigations predictable.​​
