Cyber attacks and terrorism among top threats to UK
Attacks on computer networks are among the biggest threats to the UK, Theresa May has said ahead of the publication of a new National Security Strategy.
Cyber terrorism was a "new and growing" danger, the home secretary said.
The BBC has learned there will be new money to bolster cyber security, focused on protecting critical infrastructure and defence assets.
The strategy will form the background for Tuesday's Strategic Defence Review, with defence cuts of 8% expected.
