Attacks on analog sensors in OT

Posted on 10/06/2022, by INCIBE
In order to increase security levels in OT networks, there are now solutions that monitor networks, devices and configurations, actively looking for anomalies and possible security flaws and intrusions that could take place. However, there are other types of attacks on ICS that are carried out on a completely different plane, where anomaly analysis systems can’t reach. These are attacks on analog sensors.

Secure remote access in ICS

Posted on 03/04/2021, by INCIBE
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.

SweynTooth: Bluetooth in the spotlight

Posted on 12/17/2020, by INCIBE
Wireless communications encompass a set of protocols that are widely used in some industrial sectors. In particular, building automation is based on these protocols, mainly using the BACNET and Lontalks protocols, but also making use of new ZigBee and Bluetooth based devices for IIoT. This article will provide information on SweynTooth, a set of vulnerabilities that affect Bluetooth technology.

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.
