The main function of the Information Technology Service  is the provision of comprehensive information and communications technology services to United Nations Office at Vienna (UNOV) and United Nations Office on Drugs and Crime. ITS consists of four units:

The Core Services Unit provides computer-related support including installation and maintenance of servers and desktop hardware and software; computer equipment standards; equipment and technical support for conferences and meetings; the infrastructure for enterprise resource planning applications and other office automation applications (this includes all the network components and connectivity with other UN organisations and the internet); internet access and file sharing services; e-mail and groupware services, security for application and server data and protection for the computer environment from viruses, hackers and similar threats; cellular phones, switchboard and faxing services and audio- and video-conferencing services.

The Enterprise Applications Unit provides ongoing support to the enterprise resource planning applications of UNOV and UNODC, namely the Integrated Management Information System (IMIS) of UNOV and the Programme and Financial Information System (ProFi) of UNODC. The unit also develops and supports all other workflow and administrative computer applications.

The External Systems Unit assists the different substantive work units in UNODC to implement uniform data-collection, processing, analysis and publishing systems. The aim of all implemented systems is to create an efficient and effective flow of information between national competent authorities and UNODC in a transparent manner. To fulfil these objectives, the unit is responsible for the National Drug Control System (NDS) which is provided for the use of national competent authorities to automate national licit drug control as per the requirements of the drug control conventions of 1961, 1971 and 1988 and to submit statistical returns electronically to UNODC. The unit maintains the International Drug Control System (IDS) which is used by the Secretariat of the International Narcotics Control Board to electronically collect, process, analyse and publish the data.

The Information Management Unit provides website hosting, design, development and management and application development services of systems pertaining to substantive activities like legal libraries, anti money laundering legislation database, law enforcement training database, substance abuse questionnaires, outer space objects and more.
