In December 2021, a critical vulnerability was found in the log4j library. As the library is widely used, many systems at grid operators were affected, both in IT and OT. Identifying and updating all affected software was not easy. And there was a constant risk that the exposed systems would be exploited.
In this webinar, we would like to discuss and compare the responses at different ENCS members. How was the patching of systems prioritized? What measures did members take to ensure that their critical systems were not exploited before they were patched?
ENCS members can download the invitations for the operations program webinars here.
