In addition, authorised administrators can update the data in the site through an API, which supports all the same functions as the administration user interface (with the exception of user management) - including adding, deleting and updating dataset contents, dataset metadata and supporting vocabularies and reference data.

Operational security

Operational security
Configuration and change management standard Supplier-defined controls
Configuration and change management approach All software components are tracked in a version control system. An automated continuous integration system is used to test and manage controlled builds of the overall system. New builds are only deployed after passing all tests, which include security related tests. Third party libraries used are reviewed for any known security vulnerabilities and for alignment with the overall security architecture.
Vulnerability management type Supplier-defined controls
Vulnerability management approach Vulnerabilities in third party software, such as operating systems, databases, web servers, web development frameworks, are monitored via the subscriptions to relevant mailing lists.

Most reports of security vulnerabilities require installation of a software patch or new version.

Based on potential impacts, the urgency of installing the fix is assessed. Sometimes, immediate action will be required. Sometimes, upgrading can be part of the next software release.

Because of the use of cloud servers and the automated approach to deployment, updates to the OS are implemented by setting up a new virtual server, then applying all relevant OS patches and upgrades.
Protective monitoring type Supplier-defined controls
Protective monitoring approach All errors arising in the system are reported to a tracking service, which sends email alerts to support staff. A range of potential unusual server behaviour is also monitored and leads to email alerts when certain conditions are met. Any such alert is investigated to understand the cause.

The response to a compromise depends on the severity, but in serious cases it would involve taking a server offline, then rebuilding a clean new server and loading backup data. Serious incidents are addressed immediately we become aware of them.
Incident management type Supplier-defined controls
Incident management approach Users can report incidents by email, phone or web form to our support system (currently using the Freshdesk software), where a ticket is issued.

Reports on incident resolution, or progress towards resolution are added to the ticket in Freshdesk, which the user can view at any time.

The system provides reports on numbers and types of incidents and resolution time.
