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.
I have identified a vulnerability in a device within an industrial control system... Now what? This article provides the guidelines to be followed when a vulnerability within an industrial control system is detected, and the different phases of this process.
Computers used in control systems to perform a particular process usually have high costs due to their specialisation for a very specific task. But is it possible to manage a process with a small-dimension mass-produced generic system? In some cases, yes, and this is being increasingly demonstrated by low-cost hardware available to both industry and individuals.
The problems originating from the application of patches in an industrial setting have consequently led to them being rejected by the operators. For years they were practically abandoned, but thanks to the support from security companies and IT departments they are now receiving their due credit.
Today, we are unable to picture cars without a hands-free system, TVs which are not smart and a bunch of other devices without information processing systems. This can be achieved thanks to embedded systems, the use of which entails security risks.
The constant pressure from operating costs and the halt in investments due to the crisis have made it so industrial systems have had to improve the administration of their assets in order to lower product prices, thus recurring to IT solutions. The result is that industry is changing in the way its processes are managed and operated in order to integrate them in business.
