Spatial financeWhere capital meets hazard, exposure and transition
Cybersecurity and cryptography protect the confidentiality, integrity and availability of financial systems. In this field they are applied to understand how a compromise at one firm, provider or software component propagates through trusted connections, and which testing, detection and recovery capabilities limit the damage.
Cybersecurity and cryptography protect information systems and data from unauthorised access, disruption and manipulation. They address threats that can spread rapidly across interconnected digital and physical systems. In capital markets and investment, cyber and digital resilience and digital public infrastructure, cybersecurity analysis identifies how a single compromise can propagate across sectors that share software, vendors or networks. It informs resilience requirements and cyber insurance. The canonical description is on the STEM Commons.
Red teams emulate the tactics of threat actors relevant to the institution against live production systems, following frameworks such as TIBER-EU and the testing requirements of DORA, and findings feed remediation plans.
Software components, managed service providers and shared platforms are mapped so that a vulnerability or compromise can be traced to every service that depends on it.
Algorithms, keys and certificates used in payments and authentication are inventoried, so migration to post-quantum cryptography can be planned and data at long-term risk identified.
How much of the networks an operator, insurer or lender depends on stays working after a local shock, and how much the coupling between them amplifies it. Teaching model with stated illustrative values, not a prediction.

Across the six pillars, led by Nexus Consortium
Datasets and records used by cybersecurity and cryptography on this platform, with the role each plays and the label its values carry. Sources are listed in the source register.
| Data | Role | Label |
|---|---|---|
| Security event and incident logs | Detection and incident analysis | OBSERVED |
| CISA Known Exploited Vulnerabilities and the NIST National Vulnerability Database | Vulnerability prioritisation | Published statistics |
| MITRE ATT&CK knowledge base | Mapping adversary techniques | REPORTED |
| Supervisory incident reports | Sector incident patterns | Published statistics |
| Threat intelligence sharing (FS-ISAC and national CSIRTs) | Emerging threats and indicators of compromise | REPORTED |
The exposure, loss, scenario and capital views a risk officer, supervisor or ministry of finance would ask for, with the frameworks they report against. Structures follow supervisory and actuarial practice. Values are illustrative: never prices, ratings or advice.
How a shock in cybersecurity for financial systems reaches credit, market, underwriting, liquidity and operational risk, and feeds back.
Controls are tested through red-team exercises, audits and formal analysis of cryptographic schemes. Incident data are used to check whether defences performed as intended.
| Check | How it is done |
|---|---|
| Scenario realism | Test scenarios are drawn from current threat intelligence, not generic checklists |
| Detection validation | Controls are exercised with simulated attack techniques to confirm alerts fire and are acted on |
| Recovery exercises | Backups and failover are restored in practice, with time to recovery recorded against tolerance |
| Independent assurance | Testers and internal audit are independent of the teams that run the controls |
Adversaries adapt, so historical data may not reflect future attacks. Software supply chains and legacy systems introduce weaknesses that are hard to inventory.
Cybersecurity and Digital Resilience stewards cybersecurity and cryptography for the Consortium and reviews how it is applied across platforms.
Reports is the Consortium's quarterly publication. What you know about this subject can become evidence, a case or a correction in the next edition, credited to you and published under CC BY 4.0 where it is your own work.
Never send personal data, sensitive infrastructure detail or anything you have no right to share. A contribution is reviewed before use; sending it confers no authorship or editorial rights, and sponsorship never buys a finding.
Information and enquiries are open today. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
