Elements of IT Governance
Definition of IT Risk
Every organization has a mission and in this digital age government also use automated information technology (IT) systems to process its information for better support of its objectives.
Risk management plays a critical role in protecting an organization’s information assets, and therefore its mission or objectives, from IT-related risk.
IT risk can be defined as any threat to information technology, data, critical systems and business processes.
IT risk provides an end-to-end, comprehensive view of all risks related to the use of IT and a similarly thorough treatment of risk management, from the tone and culture at the top, to operational issues.

Definition of IT Risk
Management has a responsibility to identify areas of control weakness and respond in a timely fashion to these by improving processes, augmenting controls and even reducing the cycle time between control testing to ensure that the organization is properly identifying and responding to IT risks.
