Security in the GOOSE protocol

Posted on 08/06/2020, by INCIBE
After the articles “IEC 61850 Standard, all for one and one for all” and “Multicast security in IEC 61850”, it is useful to add more information about the cybersecurity guidelines set out in the IEC 62351 standard with respect to the GOOSE protocol. An explanation will be made of the operation of the protocol, the weaknesses it presents and the appropriate security measures to protect it against possible attackers.

NTP, SNTP and PTP: what time synchronization do I need?

Posted on 03/05/2020, by INCIBE
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.

Safety recommendations for electric vehicle charging stations

Posted on 02/06/2020, by INCIBE
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.
Problems in the industry

Mitigating availability problems in the industry

Posted on 07/19/2018, by INCIBE
Given that availability is always a critical point to take into account for within industrial environments, it is necessary to prevent the attacks that denial of services cause and that affect these environments. The means of giving way to a denial of service can be diverse, much like the means of mitigating these problems. This article will review all of these points, as well as the way in which the risks derived from these attacks can be reduced.
Understanding industrial network traffic, dissectors and Lua and Kaitai

Understanding industrial network traffic, dissectors and Lua and Kaitai

Posted on 06/07/2018, by INCIBE
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.

Low cost automation

Posted on 03/22/2018, by INCIBE
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.
