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 Empty Homes Verifier is hosted by UKCloud Ltd 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. Where technically possible, real-time updates and status reports are identified and sourced from credible vendor sources, which cover a significant proportion of UKCloud’s asset population. 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, UKCloud 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 to the UKCloud NOC 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 UKCloud 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 UKCloud personnel, and incidents identified and reported to UKCloud 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.
