IT Assist is part of the NICS Shared Service Organisation whose role is to provide common ICT Services to the core NICS departments. As part of that role lies the responsibility for the provision and protection of the voice and data network infrastructures and services.
The NICS departments have retained responsibility for some bespoke, departmental specific, applications. The hardware supporting these applications again falls outside the scope of this requirement.
In order to support the centralised functions IT Assist have existing infrastructure equipment and invested in new network devices both centrally in two recently established data centres, and remotely at each location requiring service. Within these data centres IT Assist have provided a security model using a layered approach and multiple DMZs (De-Militarised Zones) isolating the various security and service zones. This model will also be applied to other satellite connections as required to fulfil our obligations under ISO 270001 and CESG Guidance for restricted networks.
