The Internet of Things (IoT) describes the network of physical objects that are installed with sensors, software, and other technologies to connect and exchange data with other devices over the internet. These devices can range from everyday household objects to industrial tools. Today, there are about 7 billion devices connected through IoT and it has been estimated that devices using this technology will increase 20 billion more by 2025.
While IoT has existed for a while, advancements in technology have made it more practical and accessible. There is an increase in security concerns that exist with this technology along with the many organizations that operate them such as healthcare, finance, manufacturing, logistics, and retail. It’s architecture typically consist of wireless networks and several components to exchange data.
While IoT projects can differ, the main architectural layers have remained consistent. With the increased use of this technology there also comes concerns to an increase in cyber-attacks on it. Distributed Denial of Service (DDoS) or Man In the Middle Attacks (MITM) are some of the common exploits used against the IoT.
Additionally, adding IoT to an organization can increase the attack surface on which a company can be vulnerable if the network isn’t sectioned off into secure zones. Like all objects connected to the internet they’re ways to help secure these devices ranging from good physical security and ensuring the firmware is updated regularly.
