Availability and resilience

Availability and resilience
Guaranteed availability ADS is hosted on a high availability cloud infrastructure with a failover backup hosted in a different geographic region for maximum resilience.

Internal availability testing indicates availability in excess of 99.6%

Response times for map rendering are typically less than 1 second at the server.

The services are continually monitored with automated messages sent to several staff in the event of a deterioration or failure.
Approach to resilience ADS is hosted within the Amazon Elastic Compute Cloud (Amazon EC2).

The entire cloud environment is backed up to a second geographic availability zone to provide additional resilience in the unlikely event that the primary availability zone becomes unavailable.
Outage reporting Astun set up a series of alarms to monitor the customer's cloud service. These alarms are triggered if any pre-set limits to system resources are reached (e.g. disk space). This enables Astun to address the majority of issues before any potential outage.

We also use our GeoHealth check system to monitor servers and ensure they are up and working.

The customer is informed of any potential problems by email or phone.

Security governance approach We are currently working towards ISO 27001.
Information security policies and processes We are currently working towards ISO 27001. Operational customer data is stored or processed within iShare in the Cloud. Information assurance accreditation has not yet been sought for iShare in the Cloud, however we consider that iShare in the Cloud would be classified as BIL0 or BIL1, users should make appropriate decisions regarding what data to deploy within iShare in the Cloud. Integration with back office systems can support the dynamic spatialisation of data sets that are not hosted within the iShare SDW for added security.

Configuration and change management standard Supplier-defined controls
Configuration and change management approach Changes to all components are managed and tracked through their lifetime via a centralised bug-tracking, issue-tracking and project-management software application (JIRA) and associated private code repository (BitBucket) managed under source control. The software is built through a repeatable build process and after passing formally defined test cases is tagged to a specific version number at the point of release. Only released software is deployed to the customer virtual private cloud environments. Potential security impacts are assessed via a process of peer review.
Vulnerability management type Supplier-defined controls
Vulnerability management approach Information on potential treats is continuously assessed through review of key online resources (release notes, security articles etc) for all third party components (operating systems, databases, frameworks etc). Penetration testing of the full system (including Astun components) is undertaken by independent third parties on all significant software releases. Whilst patch releases are routinely issued on a monthly basis, key security vulnerabilities are patched and released as soon as Astun become aware of them, irrespective of the stage in the release cycle.
Protective monitoring type Supplier-defined controls
Protective monitoring approach All cloud servers are set up with alarms that monitor key system resources on the server itself allowing the detection of compromises such as denial of service attacks. In addition external monitoring services are set up to make routine periodic requests to the servers (typically every 15 mins), to check that they remain responsive, and send out alerts if any servers are unavailable. Incidents are responded to as soon as we become aware of them. Logging is enabled on the servers to provide an audit trail of potential compromises for subsequent investigation.
Incident management type Supplier-defined controls
Incident management approach Security related incidents are categorised as a Priority 1 within our Service Desk system, and allocated to third line support personnel (developer) for immediate investigation and resolution. Users are able to report such incidents via the Service Desk (phone, email and web form), which is routinely monitored throughout the working day by first line support staff. Contemporaneous notes are taken during the incident and recorded against the service desk ticket, which provides a detailed report of the incident itself. Key performance indicators are also published from the Service Desk System and routinely reviewed by management on a weekly basis.
