- Terrain Surface height in whole metres on a grid of about 240 by 370 metres, read from one overview of the 30 m product at build time; 0 at sea. Produced using Copernicus WorldDEM-30 © DLR e.V. 2010–2014 and © Airbus Defence and Space GmbH 2014–2018 provided under COPERNICUS by the European Union and ESA; all rights reserved. read 2026-10-17. Estimate: A digital surface model: trees and roofs are in the heights. Relief exaggeration is printed on the stage.
- Ground infrastructure Satellite dishes, communication masts and towers, telephone exchanges, data centres and cable landing stations, telecom offices and aerodromes, each as one point with its tags as mapped. © OpenStreetMap contributors, ODbL 1.0. data as of 2026-06-01. Estimate: Points as mapped by contributors: a missing feature means it is not mapped, not that it does not exist; operator and height tags are kept as tagged.
- Communication cables Submarine and terrestrial communication cables mapped by OpenStreetMap contributors inside the box, clipped to it, with their length in kilometres. © OpenStreetMap contributors, ODbL 1.0. data as of 2026-07-15. Estimate: OpenStreetMap-mapped cables at the extract date; never a complete or authoritative cable inventory.
- Known exploited vulnerabilities Catalogue entries added in the last three years with six fields: CVE id, vendor or project, product, date added, due date and the known ransomware campaign use flag. Source: CISA Known Exploited Vulnerabilities Catalog (CC0 1.0), snapshot 2026-10-17, catalogue version 2026.10.16. read 2026-10-17. Estimate: A dated snapshot, never a live or complete vulnerability feed; vendor and product names are the vendors' own marks shown as data; no CISA logo or DHS seal.
- Night-time lights, VIIRS day-night band Night-time radiance for the date shown, draped on the terrain, as a proxy for where settlements and sites draw power. VIIRS SNPP day-night band at-sensor radiance, NASA, via NASA GIBS, with the product date. Live: this page requests gibs.earthdata.nasa.gov when the layer is opened; the data date is printed with it. We acknowledge the use of imagery provided by services from NASA's Global Imagery Browse Services (GIBS), part of NASA's Earth Science Data and Information System (ESDIS). Estimate: Satellite radiance with moonlight and cloud not corrected in this product; lights are a proxy, never a measurement of electricity supply, access or outages.
Why this place: One box of about 57 by 55 kilometres holds Goonhilly Earth Station (the ground segment of satellite communications since 1962 and a deep-space ground station today), the Porthcurno valley where transatlantic telegraph and later fibre cables came ashore, the Culdrose air station and the telecom masts of a rural peninsula, so the ground segment, cable landings and the resilience of positioning, navigation, timing and communication can be taught in one place. Data quality: OpenStreetMap coverage of the United Kingdom is complete for masts, dishes and named sites, Copernicus DEM GLO-30 covers the terrain in four tiles, and VIIRS night lights show where the digital economy draws power. It connects to the Space systems, space weather and navigation, cybersecurity, Digital public infrastructure and digital identity and Data infrastructure, compute and semiconductors disciplines of the atlas.

04The subject
The subject, methods and measures and debates and bodies
The field and its scope
For security leads, risk managers, resilience planners and executives who must decide what to protect, how to measure exposure and how to keep services running through attack and failure.
Quantities and units
Methods and their limits
Each method is listed with what it assumes and where it fails.
What the field debates
Bodies that set practice, and the data they publish
Bodies and standards are named so learners can find and apply their published work; the Academy teaches their use and links to the publisher, and no affiliation is implied.
05The method
From a severity score to a patch queue: why CVSS alone over-prioritises
A CVSS score measures technical severity under worst-case assumptions, not likelihood; most high and critical vulnerabilities are never exploited, so a queue built on severity alone outgrows any patch capacity, while a queue filtered by exploitation probability and confirmed exploitation can be cleared.

12Questions
Questions, answers and key terms
Is study here free?
Yes. Every course and learning material of Risk Academy, led by the Nexus Consortium, is free to study, self-paced or with a cohort. Ordinary participation has no fee; paid work, internships and fellowships are separate arrangements.
What does completing a course give me?
A completion record: the course, its version, the date and what was assessed, private by default and shared by you. It stacks into discipline, department and programme achievements. A record states what was studied and assessed and does not certify competence; it is not a licence, a professional title or an employment status.
Where do the data and the places come from?
Every faculty teaches on a twin of a real place built from open data; each layer carries its provider, licence and date, and every result on the Academy states its source. Maps and figures are indicators for teaching, never an assessment of a place.
How do I take part beyond the courses in cybersecurity and digital resilience?
Form a competence cell of three to seven people, study a shared pathway, take a supervised assignment in the National Working Groups, or bring a cohort from your institution. For organisations.
Key terms

Malware that encrypts or steals data and demands payment.
Term
Zero trust
A security model that verifies every request instead of trusting a network location.
