The tech world tends to proceed from one era to another in a roughly 10-15 year cycle. So we had the PC era from the 1980s to the mid-1990s, followed by the internet and world-wide web era, and then the post-2007 (iPhone) mobile era. Today’s tech world is dominated by mobile, social networks, the cloud, analytics (including AI and ML) and, increasingly, the Internet of Things (IoT). Going forward, these technologies are likely to coalesce into an AR/VR-mediated ‘ambient’ era, after which we’re probably looking at the incorporation of nanotechnology into human bodies and brains (the ‘cyborg’ era?).As each new technology appears, manufacturers and service providers rush to bring products to market, often without due consideration for security. Inevitably, ‘bad actors’ — including low-level hackers, organised criminals, ‘hacktivists’ and nation states — exploit the resulting vulnerabilities, stealing or compromising data, denying access to services or causing other kinds of cyber-mayhem. In due course, the tech industry gets its security act together in areas such as threat intelligence, firewalling, endpoint protection, intrusion detection, incident response, network and application architecture, best practices and user education. Governments may also weigh in with laws and regulations, and the insurance industry picks up the pieces. Eventually, some sort of order is restored.But cybersecurity remains, and will probably always remain, an arms race — especially in the early stages of an innovation cycle.So what’s the state of play today, and what’s in store down the line?
