Imagine a nation-state being able to covertly control medical equipment used to treat a high-profile politician or a country capable of accessing industrial controls used to provide electricity to millions of customers. Now consider the fact that there are billions of business devices — from basic security cameras, HVAC systems, barcode readers, smart locks and smart lighting through more sophisticated building automation systems and industrial machines — all connected within the larger Internet of Things, or IoT. The devices often go unnoticed or, if they are noticed, they are often left without adequate security controls. Cyber Security Services research suggests the following:
Change default passwords
Separate the corporate network
Prevent IoT devices from communicating with the internet unless absolutely necessary
Control which vendors are allowed remote access to IoT devices
Implement a Network Access Control (NAC) solution
Implement a vulnerability scanner as soon as possible
Run an Intrusion Detection System (IDS) or Intrusion Prevention System (IPS) on the network
Ensure proper management of all IoT devices
Restrict internal and external port communication on firewalls
Remove unsupported operating systems, applications, and devices from the network
