Cyber threat actors regularly target governments in order to access official ICT systems and data holdings.

In addition to cyber-attacks, ICT systems failures can significantly disrupt services heavily dependent on data-related infrastructure and communications such as the emergency services' ability to respond to an emergency.

Examples of significant events include the extreme threat posed by the BlueKeep remote desktop protocol vulnerability to Microsoft systems across government and an attack on ICT systems of hospitals and health services in Gippsland and south-west Victoria, both in 2019.
