The UK is to create a new cyber unit to help defend national security, the defence secretary has announced.
The Ministry of Defence is set to recruit hundreds of reservists as computer experts to work alongside regular forces in the creation of the new Joint Cyber Reserve Unit.
The new unit will also, if necessary, launch strikes in cyber space, Philip Hammond said.
Recruiting for reservists to join the unit will start next month.
The role of the unit is to protect computer networks and safeguard vital data.
"Last year, our cyber defences blocked around 400,000 advanced, malicious cyber threats to the government secure intranet alone," he said.
