Knowing the resources available when performing tasks of hardening a system, will allow us to optimize the time necessary to obtain a safer system. In addition, we have the possibility of using tools capable of auditing the system that identifies those configurations that are considered safe and which ones we could implement.
In industrial environments there are a multitude of technologies, manufacturers, communications, etc. This article will reflect a small part of the protocols that use radio frequency (RF) communications. Thanks to these wireless communications, operators in the industrial world can send a simple order to obtain information on the status of a sensor or execute control orders in the industrial environment. The importance of a good implementation, in terms of cybersecurity of these communications, is quite high since, on occasions, some of the attacks that have been investigated have an impact on the physical world, giving rise to incidents that can even result in fatalities.
The programming of PLCs is a fundamental part of the initial phases when building and designing industrial plants. About that environment, the company will base all its operations in that environment making the configuration of these controllers a critical element. When it comes to programming these devices there are a series of steps and best practices that take advantage of the native functionalities available and that involve little or no need to resort to a PLC programmer, protecting the device in a simple way with minimum spend on resource.
In recent years we have witnessed the evolution of the electrical grid and the development of new technologies produce what we know today as the smart grid. This evolution continues to this day and the trend seems to point to greater interconnection between end consumers and the grid, which increases possible attack vectors. Over the course of this article, we shall see the security measures that will be used in the electrical grid of the future.
With the arrival of industry 4.0 to companies’ productive processes, including IIoT and Cloud, the need to control and monitor the ICS that remotely make them up arises. However, said access points should be established securely and in a controlled manner, mainly due to the criticality of these assets. This article discusses good practices, tools and methods that can be used to establish remote connections to OT networks as securely as possible.
Software Defined Radio (SDR) is the result of the technological evolution of conventional analogue radio. Its characteristics and operational capability make it a versatile device with both positive and negative applications within the field of cybersecurity.
Wireless communications encompass a set of protocols that are widely used in some industrial sectors. In particular, building automation is based on these protocols, mainly using the BACNET and Lontalks protocols, but also making use of new ZigBee and Bluetooth based devices for IIoT. This article will provide information on SweynTooth, a set of vulnerabilities that affect Bluetooth technology.
With the aim of increasing cybersecurity knowledge, INCIBE-CERT has published a series of webinars in video format, so that, in a light and entertaining way, knowledge and technical aspects of cybersecurity can be expanded in various areas of interest, for both INCIBE-CERT's technical audience and anyone interested in cybersecurity.
