The supplier delivers a range of services and provides assurance to the Buyer's Independent Assurer that IT systems are compliant with National Cyber Security Centre (NCSC) standards Cyber security advice for public sector organisations \| National Cyber Security Centre - NCSC.GOV.UK The Buyer is establishing a more capable cyber function which is still defining its Target Operating Model. It is envisaged that there will be a range of shared capabilities and processes that the Buyer's service will need to align with or onboard to.

This will result in the need for additional, ad hoc services, which are not listed in the DSA Book of Work requiring Supplier support. Such requests by the Buyer shall be subject to an impact assessment, which will determine whether an additional Statement(s) of Work (SoW) is required. Where an Unforeseen Event occurs, the Supplier must, at the written request and at the direction of the Principal Security Architect, move capacity to the required operational area(s) to meet DSA needs. The Supplier will raise any consequential impact to Services for the acceptance of the Principal Security Architect. The Supplier shall ensure that all systems are operated in such a manner to support HO HOD compliance with the HMG Security Policy Framework. The Supplier shall ensure that all appropriate NCSC guidance is followed. The Supplier shall ensure protection of HMG information assets and accreditation of the solution where appropriate.
