The UK has formed a national computer emergency response team to act as a civil defence operation against nationwide hacks.
The outfit will be run by CERT-UK and Chris Gibson said it will work with partners across government, industry and academia to enhance the UK's cyber resilience.
Talking at the official launch of CERT-UK and its website Gibson said that the site will build trust, foster collaboration and both encourage and lead on sharing of information to develop the level of situational awareness we need to stay ahead of our adversaries.
Most of the work will be focused on Critical National Infrastructure (CNI) companies.
However, he said the organisation will also work more broadly across industry through the government's Cyber Security Information Sharing Partnership (CISP), now an integral part of CERT-UK.
Gibson said the national CERT will work with other national CERTs when the UK is being affected by activity originating in other countries and will assist other national CERTs, including through working with the UK National Crime Agency (NCA) when activity is tracked back to the UK.
The group will promote cyber situational awareness throughout the UK, to be an international point of contact, and to manage national cyber incidents.
