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.
Preventing the leaking of information in ICS

Preventing the leaking of information in ICS

Posted on 05/28/2020, by INCIBE
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.

Cyber-resilience: the key to overcoming incidents

Posted on 05/14/2020, by INCIBE
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.

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.

Evolving towards secure Modbus

Posted on 02/20/2020, by INCIBE
The Modbus protocol, in its TCP version, was not developed with cybersecurity capabilities in its communications. For this reason, many researchers have studied the different possibilities that could be undertaken at the technical level to incorporate a security layer in it, giving rise to a new version of Modbus/TCP called secure Modbus/TCP, which will gradually begin to be implemented in industrial communications.
