We’ve all heard the stats: in 2021, there will be 35.8 billion connected devices worldwide, rising to 75.4 billion connected devices worldwide in 2025, and the Internet of Things (IoT) security spend worldwide is predicted to be $3.1million. And these numbers will only continue to rise.

Once upon a time, ‘devices’ simply encompassed mobile phones, laptops, desktop PCs and tablets. In today’s world, however, devices are everywhere – from toothbrushes to microwaves, TVs to cars – in industries ranging from retail, to manufacturing, agriculture, banking and education. These devices aren’t just part of our lives as consumers; they play a huge role in our working lives too. From connected printers in an office to a monitoring device within a utilities plant or a food processing factory, we’re excited about the possibilities that the new world of connected technology can bring, but right now the industry simply isn’t considering the next generation of security threats that follows suit.

We know that hackers are always one step ahead, but with an attack surface that doesn’t appear to stop expanding, traditional security solutions are not equipped to protect against the advanced threats that come with this proliferation of devices.

Security as an afterthought

The problem is, despite many people talking about the next generation of security, when it comes to developing and commercializing IoT, security is often an afterthought and sometimes intentionally ignored. In reality – security, and next generation security in particular, is essential. As we see these devices everywhere, we should also be seeing security everywhere. But this isn’t the case. 

The need is for robust security designed for the highly distributed population of IoT devices – both to prevent those devices from becoming an attack vector to the network and to protect the integrity and function of the devices themselves.

Enter Software Defined Security

This is where Software Defined Security (SD-Sec) comes in. SD-Sec allows us to wave goodbye to traditional security solutions by overlaying security on top of the network infrastructure, segmenting any type of traffic and assigning specific access to users, applications and devices with full autonomy from the underlying network. Additionally, SD-Sec utilizes an orchestrated policy system to define a policy that can uniformly be applied everywhere, ensuring the risk of network-based adds, moves or changes can’t have any effect on the enterprise’s security posture.

The nature of the SD-Sec overlay means that it has the ability to define and enforce security policies uniformly over a diverse range of networks, locations and devices; this is something traditional security solutions fail to do. Managing the network from a single, centralized point gives full control to identify where a user is on the network, which applications or devices the user is accessing and which applications hackers have attempted to compromise, enabling a breach to be detected in a matter of minutes. This centralized system carries huge advantages when you consider how extensive today’s networks have become.

A new world of security

It’s clear that current security solutions just aren’t up to scratch. The mindset needs to change so that security is no longer an afterthought when it comes to IoT. Imagine a world where security policies can be defined automatically by an engine that can overlay security onto ANY device. This is the world we need to live in.
