Securing IoT: Challenges and Strategies

By 2025, it's estimated there will be over 75 billion IoT devices worldwide. This explosive growth presents immense security challenges, as the sheer volume of devices creates numerous potential attack vectors.

Many IoT devices have minimal processing capabilities, which restricts the use of advanced encryption and security measures, making them easier targets for cyberattacks compared to traditional computers.

The IoT industry lacks unified security standards. Devices from different manufacturers often have varying levels of security, making it difficult to protect a network with multiple types of IoT devices.

IoT devices, such as industrial sensors, can be in operation for decades, outliving their supported lifespans. This leads to legacy devices that may not receive security updates, posing a significant risk.

IoT devices often have complex supply chains. Components from various sources can introduce vulnerabilities, and a single compromised element can undermine the security of the entire device.

IoT devices can collect sensitive personal data. Breaches not only compromise user privacy but also pose legal challenges for companies not complying with data protection regulations like GDPR or CCPA.

IoT devices are prime targets for botnets. The infamous Mirai botnet incident demonstrated how easily IoT devices can be hijacked to launch massive DDoS attacks, disrupting global internet services.
