Trends in Security Information
The HSD Trendmonitor is designed to provide access to relevant content on various subjects in the safety and security domain, to identify relevant developments and to connect knowledge and organisations. The safety and security domain encompasses a vast number of subjects. Four relevant taxonomies (type of threat or opportunity, victim, source of threat and domain of application) have been constructed in order to visualize all of these subjects. The taxonomies and related category descriptions have been carefully composed according to other taxonomies, European and international standards and our own expertise.
In order to identify safety and security related trends, relevant reports and HSD news articles are continuously scanned, analysed and classified by hand according to the four taxonomies. This results in a wide array of observations, which we call ‘Trend Snippets’. Multiple Trend Snippets combined can provide insights into safety and security trends. The size of the circles shows the relative weight of the topic, the filters can be used to further select the most relevant content for you. If you have an addition, question or remark, drop us a line at info@securitydelta.nl.

Patching is a challenge in OT environments

Patching
Patching, the installation of software updates, is a challenge in OT environments. A patch can result in unforeseen incompatibility with connected systems, thereby disturbing the production process. This is even more of a challenge because organisations cannot simply put their systems on hold for a couple of hours. To illustrate this, respondents mentioned patching frequencies of once per quarter to once a year. To prevent compatibility issues, organisations usually wait for vendor approval for a patch. Dependent on the vendor, it can take some time before a patch can be installed, possibly leaving the system vulnerable in the meantime. Closely linked to the problem with patching is the challenge of testing OT environments.
