Information and Cyber capabilities
3.9 Information underpins all effective military operations. Secure and
resilient information systems are critical to delivering capability,
conducting operations, sharing information with partners and
communicating with other government agencies. This includes measures
to ensure that critical information and communications infrastructure,
systems and networks are defended against cyber attacks.
3.10 Investments are planned in joint command, control and communications
systems, joint electronic warfare and defensive cyberspace operations.
This investment in systems will be complemented by the establishment
of a new counter-intelligence capability, including infrastructure and
training equipment.
3.11 Defence will also invest in offensive cyber and operational cyberspace
capabilities for deployed forces, as well as systems to integrate
intelligence, surveillance and reconnaissance programs and data.
Intelligence capability will be further bolstered by continued investment
in signals intelligence and the expansion and upgrading of secure
communication systems.
3.12 This investment in strengthened Information and Cyber domain
capabilities will total around $15 billion over the next decade.
