Global spending on IoT security will reach $1.5 billion in 2018, a 28 per cent increase from 2017 spending of $1.2 billion, Gartner has said.
Despite the steady year-over-year growth in worldwide spending, Gartner predicts that through 2020, the biggest inhibitor to growth for IoT security will come from a lack of prioritisation and implementation of security best practices and tools in IoT initiative planning. This will hamper the potential spend on IoT security by 80 per cent.
While basic security patterns have been revealed in many vertical projects, they have not yet been codified into policy or design templates to allow for consistent reuse. As a result, technical standards for specific IoT security components in the industry are only now just starting to be addressed across established IT security standards bodies, consortium organisations and vendor alliances.
By 2021, Gartner predicts that regulatory compliance will become the prime influencer for IoT security uptake. Industries having to comply with regulations and guidelines aimed at improving critical infrastructure protection (CIP) are being compelled to increase their focus on security as a result of IoT permeating the industrial world.
"In IoT initiatives, organisations often don't have control over the source and nature of the software and hardware being utilised by smart connected devices. We expect to see demand for tools and services aimed at improving discovery and asset management, software and hardware security assessment, and penetration testing,” said Ruggero Contu, Research Director at Gartner.
Although IoT security is consistently referred to as a primary concern, most IoT security implementations have been planned, deployed and operated at the business-unit level, in cooperation with some IT departments to ensure the IT portions affected by the devices are sufficiently addressed.
In addition, organisations will look to increase their understanding of the implications of externalising network connectivity. These factors will be the main drivers of spending growth for the forecast period with spending on IoT security expected to reach $3.1 billion in 2021, added Contu.
