Time synchronization in industrial devices is a critical factor. In terms of time, industrial processes and the programming logic of industrial devices have specific needs. These may require specific accuracy that determines the need to use one protocol or another, as well as dependencies on cost or on the network infrastructure itself. Explaining the main differences is key when using one or another in industrial infrastructures. Just as each protocol has different nuances, there are certain differences to be taken into account within security.
Over the last few years we have seen how electric vehicles have experienced a boom in terms of their development and retail and, along with them, the deployment of their charging points. In this article we will discuss a series of requirements, in terms of security, that should be implemented in these charging stations in order to ensure their security.
Over the years, the automotive sector has been growing and evolving technologically. During this time, different deficiencies or vulnerabilities in smart cars have been discovered. For this reason, one of the key issues for this new type of vehicle is protection against possible threats.
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 defence in depth and, especially, the definition of Zones and Conduits is a subject considered by many experts as a "theoretical" matter. However, with the help of this article, the user will understand its applicability by explaining the keys to approach the creation of Zones and Conduits, as well as the elements that come into play.
Honeypots and their implementation in a network, known as a honeynet, are a powerful tool for defending your system and safely monitoring the attacks carried out against it. In this article we will detail what honeypots are, their implementation in OT environments, the advantages and disadvantages of their implementation in the system and the latest honeypots developed for industrial control systems.
Not only is the interpretation of network traffic crucial to analyse the safety and performance of a network structure, but also for other tasks, such as incident management, the optimisation of our network infrastructure or for didactic purposes. In order to do so, it is necessary to have dissectors that help separate each of the fields that make up a protocol, and allow them to be individually analysed.
From the point of view of cybersecurity, access to automation and industrial control systems is one of the most critical control points and that's why special care must be taken when it comes to applying access security and fortification policies. On occasions, it is necessary to carry out remote tasks such as, for example, maintenance, upgrading or device or application management work. Thus, external personnel outside our company may perform said tasks, including manufacturers, wholesalers or providers of services, making it necessary to protect these accesses from potential threats.
