The physical protection of ports at hardware level within embedded systems allows control of the physical access interfaces, but what happens when these interfaces are necessary? Sometimes, access via JTAG or UART to systems is required for maintenance or modifications in different industrial processes. Thanks to these accesses, suppliers can access memory addresses to read or write, modify firmware, etc. Given the importance of these tasks, it is necessary to incorporate cybersecurity into the process and it is precisely on these measures that the subject of this article will focus.
Protection against fault injections, encryption of some memory sections within microcontrollers, or simple write protection are some of the defences that can be implemented to avoid problems within an industrial infrastructure
En este artículo se presentarán algunas soluciones útiles en la realización de test de vulnerabilidades en aplicaciones Android, resaltando las oportunidades que estas tareas aportan a la ciberseguridad.
With the industrial revolution of Industry 4.0, industrial processes have become more intelligent, and this has led to the deployment of a greater number of devices.
All these deployments usually have a common point, being the gateways, which, after being deployed, are responsible for the translation of some protocols to the TCP/UDP frame or simply send the information to the cloud.
Being a point that gathers a large amount of data and capable of providing intelligence to industrial processes, industrial gateways have become a very desirable target for attackers.
One of the most important activities in the industry is the industrial maintenance because it could extend the service life of devices. This activity has always been more mechanically oriented, but currently it might talk a new type of maintenance because the new industry technologies and increase of cyberattacks.
This maintenance is more related with the informatic world and in this article will be able to see the principals characteristics and the actions to be taken to ensure that it is carried out correctly.

Currently, there is a constant evolution in the technologies and implementations made in Industrial Control Systems. On one hand, some of the most common implementations for the improvement of industrial systems infrastructures are digitalization and the use of cloud technology. On the other hand, the increase in communication protocols and IIoT devices (due to the growth of the Industry 4.0) generates a large volume of traffic that is difficult to control and secure.
Within the industrial world, there are some sectors such as robotics, which has evolver considerably. This has led to the need to update all the regulations and standards, both in terms of physical (safety) and cybersecurity. (security). Given that the robotics sector is and will increasingly become a highly technical sector with exponential growth, the need to update all documentation has been promoted by a large group of companies in the sector, which, above all, have focused their concerns on the cybersecurity of the industrial robotics world.
En este estudio, se expone brevemente el origen y evolución de la amenaza ransomware LockBit 3.0, a través del análisis de varias muestras maliciosa, con el objetivo de facilitar la información necesaria para poder identificar las características propias de este malware, su comportamiento y técnicas empleadas, permitiendo así una mejor identificación y respuesta ante ella.
Industrial Control Systems (ICS) were initially designed to work in sealed environments and as stand-alone systems, interconnections between systems were scarce, as were safety protections. The constant evolutions in the field of ICS, including the inclusion of a large number of communication protocols, IIoT devices, the expansion of interconnections, an incessant search for interoperability between systems and the inclusion of these architectures in critical systems, has meant that the networks on which these industrial control systems, has meant that the networks on which these industrial control systems are built, also known as control networks, have increased their security exponentially.
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.
