Control system networks have grown immensely in recent years, something similar to what happened with the explosion of IT networks in the 1980s. This growth is happening somewhat chaotically, promoted mainly by productive needs and by the lack of joint definition of network administration managers for IT and OT, instead of doing it by thinking of the future, scalability and security.
Security breaches that put our privacy at risk, leaks of our data, passwords... are incidents that happen more and more often. Protecting ourselves from these information leaks is often beyond our reach, but this does not mean that we should not try to take measures to protect our data. DNS-over-TLS can be very helpful in encrypting our communications, making them much more secure.
The Internet of Things (IoT) has started to become part of daily life in society: intelligent homes, intelligent education, intelligent healthcare, wearable devices, the Internet of Vehicles (IoV) and other industries make great use of this technology, with it playing a key role in the digital transformation and the hyper-connection of their elements.
Tomando en consideración las amenazas y los riesgos detallados anteriormente queda de manifiesto la necesidad de desarrollar acciones o modelos de protección para mitigar las vulnerabilidades que surgen del tratamiento de los datos de los usuarios así como prácticas de seguridad en la funcionalidad y el despliegue de tecnologías IoT.
Sometimes it is necessary to make some adjustments to control system devices, which leads to a reprogramming of PLC, RTU and similar devices. Reprogramming is a complicated step in terms of security and if the process is not adequately executed, the entire process of which the device is a part may be at risk.
Blockchain is in fashion. Every month, new systems of this type emerge, applications that use them or companies who base their business models on the opportunities provided by this technology. Despite this boom, there is still a lot of uncertainty surrounding the protocol.
Today there is not a mobile phone on the planet that does not feature Bluetooth technology to connect to other wireless devices. To add to this, the emergence of the Industrial Internet of Things (IIoT) has generated multiple vectors of attack through this technology.
