GCRI · Global challenges

Digital and cyber dependencies

Public services, finance, health care, logistics and energy now run on software, networks, cloud platforms and satellites. A faulty update, a compromised supplier or a regional cloud outage can stop many services at once. The Global Centre for Risk and Innovation (GCRI) maps connected service dependencies and how technology shifts them, so institutions see them before they fail. Part of global challenges.

02The challenge

Digital dependence is deep, shared and often invisible.

Concentration

Few providers, many users

Cloud regions, operating systems, identity services and payment rails are shared by thousands of organisations.

Supply chains

Software built on software

Open-source components, vendor updates and managed services carry risk from one organisation into many others.

Physical layer

Cables, power and space

Subsea cables, data-centre power and cooling, and satellite timing services link digital risk to physical hazards.

03Reference frames

The frameworks that define cyber and digital resilience in 2026.

FrameworkBody and dateWhat it sets
Cybersecurity Framework 2.0NIST, 2024Six functions (govern, identify, protect, detect, respond, recover) for organising cyber risk management
NIS2 DirectiveEuropean Union, 2022, applied from October 2024Security and incident reporting duties for essential and important entities
Cyber Resilience ActEuropean Union, Regulation 2024/2847, applying in stages to 2027Security requirements for products with digital elements across their life
Post-quantum cryptography standards FIPS 203, 204 and 205NIST, August 2024Key encapsulation and signature algorithms intended to resist quantum attack
ATT&CK knowledge baseMITREA shared vocabulary of adversary techniques used in threat modelling

These are named as references. GCRI claims no conformity with any of them; organisations assess themselves or are assessed by the competent bodies.

04How digital failure spreads

Mechanisms of propagation, and the measures that describe exposure.

MechanismHow it spreadsMeasure of exposure
Faulty updateOne defective release reaches every system that installs it automaticallyNumber of services on one update channel; rollback time in hours
Software supply chain compromiseA compromised component or build system passes into many productsSoftware bill of materials coverage; depth of dependency trees
Concentration in shared platformsMany organisations depend on the same cloud region, identity service or payment railShare of critical services hosted in one region or provider class
Physical couplingSubsea cables, data-centre power and cooling, satellite timingCable route diversity; hours of backup power; timing holdover duration
Harvest now, decrypt laterEncrypted data captured today may be read once quantum computers can break current public-key schemesVolume and lifetime of data protected only by RSA or elliptic-curve keys

Incident data are the weakest link. Reporting regimes are new and differ by jurisdiction, many incidents are never disclosed, and annual threat landscapes such as ENISA’s rest on reported cases. Studies state that limit next to every estimate.

05GCRI’s part

Dependency research, not incident response or threat intelligence.

GCRI maps service dependencies, studies propagation and helps public institutions plan migrations such as the move to post-quantum cryptography. It runs no security operations, publishes no vulnerability detail and responds to no incidents; national computer emergency response teams hold that role. Field work sits with the Cybersecurity and Digital Resilience platform and the Digital Public Infrastructure platform.

Public findings are designed for the Exponential Technology series; software and models used in the programme would carry bills of materials and model cards under NS-12 of the proposed Nexus Standards. Helpful contributions are anonymised dependency structures, post-incident reviews an organisation chooses to publish, and migration lessons from cryptographic inventories.

06What changes with technology

New capability brings new exposure.

  • AI systems embedded in services add model failure and misuse to existing cyber risk
  • Quantum computing is expected to weaken some current public-key cryptography, so long-lived data needs planning now
  • Digital public infrastructure widens access and concentrates dependence on identity and payment systems
  • Connected industrial control systems bring operational technology within reach of network attacks
07How GCRI approaches it

Dependency evidence, not threat intelligence.

GCRI maps service dependencies, studies how failures propagate and tests resilience options in controlled settings, drawing on cybersecurity and cryptography and safety-critical systems engineering. Field work is organised through the Cybersecurity and Digital Resilience platform and Digital Public Infrastructure platform.

GCRI is not an incident response service and does not monitor networks. Report a vulnerability in a GCRI service to the security address.

08Across the programme

Governance and finance perspectives.

The Global Risks Forum (GRF) examines institutional choices under digital and AI governance. The Global Risks Alliance (GRA) examines financial-sector exposure under cyber and operational risk. See also infrastructure dependencies and the cyber and digital resilience field gateway.

10Questions

Questions and answers.

Can GCRI help during a cyber incident?
No. GCRI does not provide incident response. Contact your national computer emergency response team or your service provider. GCRI’s work is preparatory research and testing.
How do I report a security issue in a GCRI website or service?
Write to the security report form with a description of the issue. Do not include personal data or exploit material beyond what is needed to understand it.
Does GCRI publish vulnerability details?
No. Public pages describe mechanisms and reviewed findings. Sensitive technical detail is handled under agreed terms and is not published.
Why include digital public infrastructure?
Identity, payment and data-exchange systems serve whole populations. Their benefits are large, and so is the effect of their failure, which makes their dependencies a public question.
