The head of MI5 is to urge the public to be as vigilant about threats from "hostile states" as from terrorism.
These include disruptive cyber-attacks, misinformation, espionage and interference in politics - and are usually linked to Russia and China.
In a speech on Wednesday, Ken McCallum will say these "less visible threats... have the potential to affect us all".
He will say these threats are affecting UK jobs and public services and could even lead to a loss of life.
