Imagine if someone told you in the early 2000s that entire industries would run almost by themselves, thanks to a network of connected devices. Today, this is no longer science fiction but our reality, thanks to the Internet of Things (IoT). By 2030, it’s expected that there will be over 29 billion IoT devices globally. These devices are transforming critical infrastructure like power grids, water systems, transportation networks, factories, military bases, and airports, making them more efficient and reliable.
How IoT is Changing Critical Infrastructure
IoT is revolutionising how we manage and operate our critical infrastructure. These devices allow for real-time data collection, remote monitoring, and automation. This means that systems can run more smoothly, costs can be reduced, and services can be more reliable. However, setting up these networks over large areas isn’t easy. It requires substantial investment and upgrades to existing infrastructure.
The Cybersecurity Challenge
With so many devices connected, the security risks increase. Many IoT devices don’t have strong security features, making them easy targets for hackers. Here are some specific concerns:
1. Unauthorised Access: Many devices come with default passwords that are easy to guess, making them vulnerable to attacks.
2. Data Breaches: If data isn’t encrypted, it can be intercepted and misused.
3. Denial of Service (DoS): Networks can
