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.

Sandboxing and network segmentation
In computer security, sandboxing and network segmentation are security mechanisms to limit access to software-, computer- or network functions and systems. It fits in a limited- or zero-trust management philosophy. By separating running programs, systems and networks, the impact of system failures can be limited, software vulnerabilities have less impact and limited connections hinder malware from spreading.
Sandboxing is often used to execute untested or untrusted programs or code, possibly from unverified or untrusted third parties, without risking harm to the host machine or operating system. A sandbox typically provides a tightly controlled set of resources for guest programs to run in, such as storage and memory scratch space. It is frequently used to test unverified programmes that may contain a virus or other malicious code. Network access, the ability to inspect the host system or read from input devices are usually disallowed or heavily restricted. In the sense of providing a highly controlled environment, sandboxes may be seen as a specific example of virtualisation.
Network segmentation is similar in goals but on the system or network level. Micro-segmentation is a method of creating zones in data centres and cloud environments to isolate workloads from one another and secure them individually. It is used to reduce the network attack surface, improve breach containment (prevent lateral movement of threats) and strengthen regulatory compliance.
