Onboarding and offboarding

Onboarding and offboarding
Getting started 1. Every organisation is registered in our database
2. At least one organisation member of staff needs to be registered in our database
3. Every user for every organisation should be registered; each person is given a unique username and password
4. Each user will be required to authenticate themselves with their username and password when accessing the Services for the first time whenever they invoke the service from within their application
5. Any organisation can register additional users at any time
6. Any new PSMA/OSMA signatory will need to be forwarded to emapsite by the appropriate Contract Manager and the above process replicated
Service documentation No
End-of-contract data extraction Service migration of specific APIs is limited owing to nature of a model built on highly optimised web service components delivering content from very specific geographic data stacks. The services are highly interoperable and extensible, for example to other data stacks.
User data extraction includes the facility to retrieve all user interaction and user generated data including transaction logs and database schemas as applicable; any such data would typically be provided as CSV or XML.
Subject to audit requirements emapsite will purge and destroy consumer data from any computers, storage media or storage devices at the end of a subscription period.
Indicative time for de-provisioning (to close and off-board any service) is one week (though contractual obligations may have a different term in relation to cancellation of service).
End-of-contract process Typically 3 months notice is required unless there is a material and persistent breach of any of the obligations agreed under a Call Off or other Contract under the G-Cloud framework or if a change of control of the Supplier causes conflicts of interest or other competition issues.
There are no additional costs at termination.

Independence of resources Like most platforms we rely on over-provisioning for each service in line with the number of users and patterns of usage, spinning up additional resources as necessary for any specific service. In addition owing to typical usage levels we separate the WMS/WFS and the WMTS requests onto discrete hardware. Tile size constraints form part of the service level agreement.

Availability and resilience

Availability and resilience
Guaranteed availability Internal auditing shows WMS/WMTS/WFS availability at 99.85% on 24*7*365 basis and 99.95% on a working hours basis.
emapsite offers a service credit package upto 10% of the per service delivery period contract value; this is assessed according to details agreed in the customer service level agreement and typically provides for a credit for failure to deliver required services to the agreed availability level for the specified service delivery period.
Approach to resilience To ensure high resilience and security emapsite’s infrastructure is hosted at ISO27001 certified Equinix’s latest Tier 3+ datacentre facility near Heathrow. Access to the data centre is controlled by access cards, visual and biometric identification, CCTV, breach alarms and controlled physical barriers. The data centre has fully redundant power with UPS and diesel generators and is serviced by multiple high speed low latency fibre. Access is secured via customer specific API key with full session and user logging.

- Dual zone, single site facility
- Multiple servers including 16-bay blade servers
- Two switches in each zone
- Duplicated firewalls
- All servers are dual power supply from independent power sources
- Virtualised cloud model
- Load balancing by service with a failover/heartbeat redundancy model
- All key data on RAID-10 arrays
- Arrays replicated in each zone
- Original source media stored securely off-premise
- Load balancing allows for atomic switch over to new front-end, back-end or database servers
Outage reporting Continuous monitoring using Pingdom, nagios and other bespoke tools all linked to text and email alert system.

"To the extent that there need be exclusions:
• While the Company has a number of staff on home-working contracts it is satisfied that those contracts and the stipulations therein exclude additional teleworking controls (A.6.2.2 of ISO27001:2013).
• The Company is satisfied that system architecture including RAID storage, dual zones, load balancing, clustering and virtualisation together with near real time database mirroring make traditional formal “backup” procedures redundant (A12.3)"
ISO 28000:2007 certification No
CSA STAR certification No
PCI certification Yes
Who accredited the PCI DSS certification Security Metrics

Information security policies and processes A number of internal processes are subject to internal audit on an annual basis including data separation. In addition the following policies are integral elements of emapsite's Integrated Quality and Information Security Management Systems Assurance Manual underpinning the relevant controls within the Statement of Applicability:
- Access Control
- Business Continuity
- Change Management
- Data Security and Separation
- Impact Statement
- Incident Management
- Information Asset Management
- Information Classification
- Information Systems Security
- Operations Security
- Patch Management.
The policies inform system architecture and monitoring.
emapsite's Assurance Committee (AC) meets twice yearly to review the approach to risk and the currency of the controls and policies that surround that risk appetite and any specific new risks. The AC reports to the Board annually.

Operational security

Operational security
Configuration and change management standard Supplier-defined controls
Configuration and change management approach The change control process includes the following phases:
• Logged Change Requests giving full tracking in code repository
• Identification, prioritisation and initiation of change
• Proper authorisation of change (Impact Statement as applicable to identify potential infosec issues )
• Requirements analysis
• Inter-dependency and compliance analysis (to consider infosec impacts)
• Impact Assessment
• Change approach
• Change testing
• User acceptance testing and approval
• Implementation and release planning
• Documentation
• Change monitoring
• Defined responsibilities
• Emergency change classification parameters.
Vulnerability management type Supplier-defined controls
Vulnerability management approach Annual risk assessment process identifies threats (physical damage, natural events, loss of essential services, compromise of information, technical failure, unauthorised action and compromise of functions as well as HR centred risks) and vulnerabilities (hardware, software, network, personnel, site, organisation) to create the basis for high level scenario modelling and risk treatment process. At the same time perimeter and network monitoring tools together with WSUS and equivalent patching routines ensure day to day threat mitigation. Systems administrator oversight together with triggers and automation streamline processes while suppliers and industry sources provide topical information.
Protective monitoring type Supplier-defined controls
Protective monitoring approach Information classification is used to determine whether any data supplied by users and customers is high impact level data (in line with GPG13). Systems monitoring including access control logs and exception monitoring of external requests (for example for SQL injection or PPTP VPN login attempts from suspicious places) provides an understanding of how our IT systems is being used or abused by internal or external agents.
Incident management type Supplier-defined controls
Incident management approach For some common possible events we have pre-defined mitigation processes including auto screensaver for unlocked laptops and encrypted hard drives.
Incidents must be reported and logged. Those dealing with security incidents shall:

• analyse and establish the cause of the incident and take necessary steps to prevent recurrence
• ongoing reporting to all affected parties
• identify problems arising from the incident and to prevent/reduce further impact
• ensure all system logs are securely maintained
• ensure only authorised personnel have access to systems and data
• ensure all corrective and preventative measures are implemented and monitored for effectiveness
