The table below has been determined from OGDs', and specifically CTO Council's, input as the highest priority topics for required 'Common Good' capability.

• Seamless interconnection and exchange between the existing secure data transfer systems serving various communities over networks in central government and the wider public sector, including local authorities, health, criminal justice and the police forces.
   
• Packaged solutions for all organisations within or outside the secure government networks, to enable integration and connection with the proposed pan-Government SDT capability for external transfers, which is likely to build out from the current Government Gateway services including authentication.
   
• Provision of services to support secure document and message exchange between individuals both within and beyond secure government networks, who need measures to protect sensitive, personal or 'need to know' content where standard email or automated data transfer remains inappropriate.
   
• Provision of application and connectivity services to support knowledge management and collaborative working for communities of interest both within government, as well as extending beyond government ICT infrastructure boundaries.
   
• While HMG should in time minimise the use of removable media, requirements for the exchange of data using assured and appropriately secured removable media solutions remain, for the time being, at various levels of protective marking.
