Log4Shell: Why the BSI recommends anomaly detection

In its working paper "Critical Vulnerability in Log4j - Detection and Response", the German Federal Office for Information Security (BSI) underlines the persistent and complex danger of the Log4Shell vulnerability in industrial networks as well. Patching the vulnerability in the short to medium term is considered unrealistic for many companies. For this reason, the BSI recommends continuous monitoring and analysis of network communication via anomaly detection in addition to rule-based query analysis. Industrial anomaly detection solutions, as offered by Rhebo, a Landis+Gyr Company, enable companies to detect on compromises that have already occurred, active exploits and other malicious activities in the operational technology (OT) and industrial control systems (ICS) at an early stage. The vulnerability, documented as CVE-2021-44228, allows attackers to execute arbitrary code on systems using the widespread Log4j library without authentication.

Information Security is Not An Add-on

The Internet of Things (IoT) opens the gate for endless opportunities in the energy sector. Unfortunately, such diverse opportunities can arouse another type of energy: the malicious one. The threat of unanticipated security breaches is not only about loss of income or reduced customer satisfaction, but finally about consumer privacy and ultimately about electricity network stability.

EU introduces first legislation in cyber security

Cyber security is widely discussed in the energy sector, but until now it has been rather unclear in many energy utilities how to start developing it in concrete business terms. This summer, two announcements in the EU provide guidance from the regulatory side and support in defining the direction of the next steps. For the daily management of information security, industry standards provide a practical framework.
