Focus on Mandatory Requirements MANDATORY REQUIREMENT 11: Departments and Agencies must apply the Protective Marking System and the necessary controls and technical measures as outlined in this framework. MANDATORY REQUIREMENT 33: Departments and Agencies must, in conjunction with the Protective Marking System, use Business Impact Levels (ILs) to assess and identify the impacts to the business through the loss of Confidentiality, Integrity and/or Availability of data and ICT systems should risks be realised. Aggregation of data must also be considered as a factor in determining ILs.

Focus on Mandatory Requirements MANDATORY REQUIREMENT 32: Departments and Agencies must conduct an annual technical risk assessment (using HMG IA Standard No.1) for all HMG ICT Projects and Programmes, and when there is a significant change in a risk component (Threat, Vulnerability, Impact etc.) to existing HMG ICT Systems in operation. The assessment and the risk management decisions made must be recorded in the Risk Management and Accreditation Documentation Set (RMADS), using HMG IA Standard No.2 – Risk Management and Accreditation of Information Systems.

Focus on Mandatory Requirements MANDATORY REQUIREMENT 36: ICT systems that process protectively marked Government data must be accredited using HMG IA Standard No. 2 – Risk Management and Accreditation of Information Systems, and the accreditation status must be reviewed at least annually to judge whether material changes have occurred which could alter the original accreditation decision.
