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.

Spectrum technologies
Spectrum technology includes all forms of technology that use invisible radio frequencies, which are used to transmit wireless signals. These wireless signals are used in telecommunication and radiocommunication technologies, such as Bluetooth, WiFi, 1/2/3/4/5G networks, radar and Low-Frequency Array (LOFAR). Wireless signals cannot be seen with the human eye, seen that electromagnetic, acoustic and electrical signals are used.
Various techniques, such as frequency hopping, time scrambling, and direct sequence spreading are forms of spread spectrum, in which signals are transmitted in a bandwidth that is greater than the frequency of the original information. Signals are used in a larger bandwidth in order to secure communications, prevent detection and create a barrier against natural interferences such as noise and jamming. There is a continues development of new connection types with specific qualities, like with the development of next generation mobile networks. There are also threats against spectrum technologies, a signal may be spoofed or jammed, have interference induction or radiation, but also be eavesdropped on, intercepted or sessions may be hijacked.
