In previous articles an introduction was given to the 61850 regulation and the different protocols of which it consists. As explained in those articles, the GOOSE and SV (Sample Values) protocols, included in the standard, use multicast frames. Security is very difficult to implement in this type of frame, but there are a number of measures that make possible to raise the security level.

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.
The attacks on the Saudi Aramco oil refinery have highlighted the vulnerabilities of these plants against physical attacks using drones. There’s a wide variety of physical and cyber attacks that use drones, from launching explosives, to capturing images, invasion of privacy or taking screenshots of Wi-Fi traffic, so companies should take new defense measures in order to protect their assets
Around 4 million robots are expected to be introduced in the area of industry over the next five years. This is on top of the evolution towards industry 4.0, in which industrial robotics is crucial, and which is now consolidated in any industrial process, from the manufacturing industry to any large-area warehouse. In that industrial transformation, barriers must be applied to ensure the integrity of the components and to prevent incidents in plants.
This post presents some lines of action to be followed in the case of having fallen victim to Ekans ransomware. It describes in detail the prevention, identification and response phases to be carried out.
In this new blog entry, we will analyze the features and describe the operation of a new ransomware called Ekans, initially known as Snake, which has a very specific design, aimed at infecting and blocking Industrial Control Systems (ICS).
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.
Exfiltration of data, or information leakage, poses a threat to all companies throughout the world. It is important to know the possible ways information can get out to control them and avoid a loss of information in our organisation. Since in industry the most important factor is availability, this threat has to be put into perspective.
The goal of cyber-resilience for an organization, whether or not it belongs to a strategic sector, whether or not it provides one of these digital services, is to maintain its primary purpose and integrity in the face of a cybersecurity threat or attack to an ideal level. Continuous detection processes must be established given that total prevention will never be guaranteed.
