Internet of Everything

The Internet of Things (IoT) is a topic that’s beginning to gain quite a head of steam lately, particularly when it comes to security concerns that accompany it. Billions of new devices, most of which are in insecure locations. You don’t own them; oftentimes can’t see them; and you don’t control them in any way, shape, or form. Yet they’re sending petabytes of data through your network. It’s enough to make a security professional lose sleep for weeks at a time.

But while many security professionals are focusing on these challenges, there’s also a huge security benefit that will come in the form of IoT enabled security! Remember, IoT isn’t about the devices themselves, it’s about the network of devices – the benefits from having all of those devices work together to produce actionable intelligence. In a similar vein, securing IoT networks can’t be about the individual security devices, but rather the network of security devices, so that they can work together to produce comprehensive, actionable security intelligence in near real-time – increasing the organization’s overall security posture with little or no human intervention required.

manufacturing To get a better sense of what I’m talking about, let’s use a real-world example. These are complex, fast-paced environments that present extraordinary safety and security challenges. A typical factory floor consists of thousands of uncontrolled access points, and therefore requires multi-layer role-based security. Security controls need to identify the person and the machine to make a determination as to whether or not that person is authorized to operate that specific machine; they also need to validate that the person is who they claim to be, prior to granting access. Integrity of the safety system is also essential, so analytics need to play a major role to proactively recognize potential catastrophes.

Currently, the various safety and security systems don’t work together which limits visibility and control. It’s one thing to know that a piece of equipment is at imminent risk of failure, but without the ability to shut that equipment down automatically, human intervention is required which can take too long to be effective. This is where IoT enabled security can help enormously. By combining numerous systems, including cyber security, cameras, and sensors, IoT enabled security can improve employee safety and protect the entire system from the outside, as well as the inside.

Consider these IoT-enabled security responses for our connected factory example:

So while IoT certainly has its security challenges, let’s not lose sight of the fact that if applied properly, those same IoT dynamics can dramatically improve safety and security capabilities, as well as response times!
