The UK’s approach to operational resilience and cloud services: balancing support for digital innovation with operational resilience?
The much-vaunted shift to the cloud (a development intended to deliver significant cost savings and allow for easy scalability) brings with it a significant risk of systemic market failure as firms outsource business continuity responsibility to a small pool of major multinational tech players. And with part of their delivery also dependent on a decentralised network of data centers and third-party service providers, a small outage at any link in the supply chain can have a significant ripple effect across the whole economy.
Studies examining the costs flowing from a cloud provider outage estimate global losses ranging from USD 4bn-53bn (for an outage duration of between 0.5-3 days
To set the scene, consider the sheer size and reach of the global cloud market.
In 2021, 5 Infrastructure as a Service (IaaS) providers accounted for over 80% of the market[1]. Nearly two-thirds of cloud infrastructure spend was captured by the world’s top three hyperscale providers.[2]
Both the EU and the UK are revising the Network and Information Systems Regulations (NIS), again to tighten up perceived gaps in cybersecurity defences. The UK is focusing on supply chain cybersecurity risks, in particular, those posed by the mass adoption of managed services. Managed service providers (MSPs) have the ability to access the networks of thousands of other companies. A vulnerability in one such service provider then risks exposing the networks of all its customers and potentially jeopardises the running of critical infrastructure – a classic ‘weakest link’ effect. The UK will therefore extend current NIS measures to MSPs, with fines for non-compliance and increased incident reporting. The EU’s approach is sector-based, expanding the remit of NIS to cover all medium and large organisations across a number of sectors, as well as addressing cybersecurity of the ICT supply chain, covering business-to-business ICT service management. The UK also launched a May 2022 consultation on the UK’s data storage and processing infrastructure, covering cloud platform infrastructure and MSP infrastructure.
The UK’s reform proposals reflect a deepening regulatory interest in managing the UK’s reliance on third party processing services and large-scale data storage to deliver essential services. But financial service firms cannot afford to be complacent and assume responsibility for managing this type of risk has been outsourced to regulators. The two pronged approach will involve more scrutiny of service providers’ service offerings and increased regulatory oversight, whilst their financial services customers will need to continue to demonstrate they have appropriate operational resilience measures in place.
