The basic service is available during normal business hours (09.00 – 17.30 Mondays – Fridays, excluding public holidays). We provide an email address for incident reporting and will respond to any notification within 4 hours. If an incident results in loss of service we will restore the service within 1 business day; in all other cases we will use reasonable efforts to resolve the incident as quickly as possible.
Support available to third parties Yes

Onboarding and offboarding

Onboarding and offboarding
Getting started We offer support in getting started with our dedicated Linked Data Publishing service under Cloud Support. We also provide training via our Linked Data Training Service.
Service documentation Yes
Documentation formats

End-of-contract data extraction No user data is collected by the system – the only data stored on the publishing platform is data supplied by the client. On termination of the contract all client data will be securely deleted. During the life of the contract clients can request access to a copy of all the data stored on the system. We have also supported public sector clients in transitioning the technology to their own infrastructure.
End-of-contract process On termination of the contract all client data will be securely deleted. We can support clients in transitioning the technology to their own infrastructure or alternatives at additional cost.

What users can and can't do using the API For all service levels an API is provided for access to the data. Full customization of this API is possible through our Linked Data Publication service.

For the fully flexible service level, with DMS option, an API is provided to enable automated update, conversion and publishing of data updates.

On-boarding of new data sources and new data formats, is not available through the API but requires configuration through our Linked Data Publication service.

Test environments can be provided under our fully flexible service level and configured using our Linked Data Publication service.

Data-in-transit protection
Data protection between buyer and supplier networks TLS (version 1.2 or above)
Data protection within supplier network

Other protection within supplier network Network operates as a Virtual Private Cloud (VPC) within Amazon Web Services infrastructure providing full subnet isolation. Administrator access is through passwordless ssh and TLS (>1.2).

Availability and resilience

Availability and resilience
Guaranteed availability We typically host services on AWS who provide no availability guarantees, so we do not offer an SLA on availabilty. In practice, however, we achieve more than 99% availability.
Approach to resilience Apart from our entry level service all services are offered on replicated servers operating in different availability zones.
Outage reporting Industry standard automated monitoring (Nagios) is used to detect outages at both service level and individual servers. Performance metrics dashboards are used to identify developing situations which can be mitigated before outages occur. Outages are notified via a messaging service (typically configured for email delivery) and a real time dashboard.

Identity and authentication

Security governance

Named board-level person responsible for service security Yes
Security governance certified No
Security governance approach We take security of our service seriously. All management of the service take place over encrypted channels (TLS/SSH). The service runs in a Virtual-Private -Cloud with full subnet isolation which limits the attack surface. Instances of the service have been subjected to several formal penetration tests by external third-parties and been approved. Any (minor) weaknesses discovered by testing have been mitigated. We use shared infrastructure management cookbooks to embody best-practice for server configuration. We perform regular service updates to apply security patches for underlying software. We subscribe to security-alert channels for that software and apply emergency security patches if necessary.
Information security policies and processes Information security is the responsibility of all employees, who are expected to be aware of security best practice and to apply it in ways commensurate with the nature of our service and of the data we hold. We have a flat management structure and it is the responsibility of the company directors to ensure appropriate security best practice is applied.

We plan to move towards ISO27001 accreditation, and anticipate further formalization of our security policy and processes as this proceeds.

Operational security

Operational security
Configuration and change management standard Supplier-defined controls
Configuration and change management approach All components of the service are subject to source code management control, with full version history, using git. This includes service configuration elements, provisioning scripts and operations cookbooks as well as code artefacts. The configuration version applied to a given service deployment is managed through IT automation infrastructure (Chef server) which maintains a history of configuration versions and enables rollback. Each developer is expected to take into account relevant factors in any change including security and operational stability, and can call on peers to help assess impacts where appropriate. Our flat management structure facilitates use of peer review.
Vulnerability management type Supplier-defined controls
Vulnerability management approach Instances of the service have been subjected to several formal penetration tests by external third parties and been approved. When appropriate lessons learned from these tests are embodied in operational cookbooks to ensure they are applied to future systems.

We maintain a regular maintenance schedule for update of service components and have automation to simplify the update process. All services are updated at least monthly and typically more frequently. We subscribe to security alert channels for relevant software and adjust our update schedule if priority patches are needed, including performing out-of-hours emergency patching when necessary.
Protective monitoring type Supplier-defined controls
Protective monitoring approach Our protective monitoring processes are tailored to the nature of our service. As an open data service provider our most significant vulnerability is denial of service, including accidental denial of service from bad clients. We detect this through automated service availability monitoring, real time performance metric dashboards and server logs. Responses include blocking requestors, rate throttling, and modifying service API implementation to remove DOS vulnerabilities. Responses times are detailed under service levels.

System compromise leading to data change would be detectable through server logs recording authorization requests and update transactions. Data is redundantly stored at multiple levels enabling quick recovery.
Incident management type Supplier-defined controls
Incident management approach We provide extensive monitoring for our services; most incidents are detected by our own monitoring, though we provide an email mechanism for users to report incidents. Following an incident we provide an email summary to any affected customers.
