Customisation available
Description of customisation
Opus is fully customisable.
Customisation can be performed via a superuser account.
Opus is supplied with a large variety of pre-configured case templates to get you up and running as soon as possible. The client can customise the inbuilt templates or build their own to match the data you want to record against case type. You can create, edit, remove case data fields to make sure you capture the case information you to.
Opus incorporates its own document management system, so that all case documents are store in one place, are readily accessible and can be searched and data matched within the Opus System.
Case workflow can be separately customised for each case type. Tasks, activities and actions can be created manually or setup and customised to be triggered automatically by case events. These can be used to manage and control the case type workflow so it supports and complies with your processes and procedures. Case decision points and ‘check-gates’ can be customised for each case type to ensure that all activities and actions are completed before the user/officer can move the case on to the next stage.


Independence of resources
The availability and performance of the Opus service is monitored full-time and alerts raised to Datatank support staff when service capacity is limited. Additional compute resources can be made available at short notice.
In order to guarantee that users are not affected by the demands from other users, we use resource reservations and shares such as internet bandwidth shaping. In addition, the capacity planning team ensure that usage in terms of all resources are constantly monitored and increased accordingly relating to user demand.

Operational security

Configuration and change management standard
Supplier-defined controls
Configuration and change management approach
Datatank has documented configuration and change management policies and processes, which have been implemented, maintained and assessed in accordance with the guidance from ITIL v.3 and the current ISO20000 standard. Formal configuration management activities, including record management and asset reporting, are monitored and validated constantly, and any identified discrepancies promptly escalated for investigation. A robust, established process for the formal submission of change requests is mandated prior to review and approval of the daily Change Advisory Board, which is attended by a quorum of operational and technical management personnel.
Vulnerability management type
Supplier-defined controls
Vulnerability management approach
Opus is hosted by Amazon Web Services who has a documented vulnerability management policy and process, which have been implemented, maintained and assessed in accordance with the guidance from ITIL v.3 and the current ISO20000 and ISO27001 standards. For other systems and software, assigned personnel have responsibility for regularly reviewing technical forums and specialist groups to promptly identify and evaluate any emerging patches or updates which require our attention.
Protective monitoring type
Conforms to a recognised standard, for example CSA CCM v3.0 or SSAE-16 / ISAE 3402
Protective monitoring approach
Following best practice from the National Cyber Security Centre, Amazon Web Services protects both its Assured and Elevated platforms with enhanced protective monitoring services (SIEM), at the hypervisor level and below. Our approach to protective monitoring continues to align with the Protective Monitoring Controls (PMC 1-12) outlined in CESG document GPG13 (Protective Monitoring for HMG ICT Systems). It includes checks on time sources, cross-boundary traffic, suspicious activities at a boundary, network connections and the status of backups, amongst many others. All alerts are immediately notified by AWS for prompt investigation.
Incident management type
Conforms to a recognised standard, for example, CSA CCM v3.0 or ISO/IEC 27035:2011 or SSAE-16 / ISAE 3402
Incident management approach
Amazon Web Services has a documented incident management policy and process, which have been implemented, maintained and assessed in accordance with the guidance from ITIL v.3 and the current ISO20000 and ISO27001 standards. This activity is responsible for the progression of alerts generated by automated monitoring systems, issues identified by AWS personnel, and incidents identified and reported to AWS by its customers and partners. All incidents are promptly reported into a central ticketing system, which ensures that each is promptly assigned to an appropriate resource, and its progress tracked (and escalated, as required) to resolution.
