States’ use of cyber operations

28 Oct 2022 12:08 PM

States are increasingly engaging in cyber operations to support their strategic aims. This POSTnote considers hostile state-backed cyber activities against the UK. It looks at how and why states use cyber operations against other nations and the threats these pose to the UK. It also considers mitigation measures, both internationally and in the UK.

‘Cyberspace’ typically refers to digital networks used to store, modify, and communicate information. It includes the internet but also other information systems that support businesses, services and infrastructure.

‘Cyber operations’ aim to achieve objectives in or via cyberspace. They can include gaining unauthorized access to computers, systems or networks to obtain information; and altering, deleting, corrupting or denying access to data or software.

States conduct cyber operations against adversaries for reasons including to gather information, influence political decisions, support military action or gain financially. Potential impacts include data breaches, website outages, and disruption to online services, telecommunications and supply chains.

The number and sophistication of cyber-attacks on the UK are increasing. In 2020/21, the National Cyber Security Centre (NSCS) dealt with 777 incidents (from non-state, as well as state, attackers), a rise of just over 30% in four years.

The UK Government set out plans for protecting and promoting UK interests in cyberspace in the National Cyber Strategy 2022. This included £114 m of extra funding for the National Cyber Security Programme to help deliver the Strategy over the next three years, which is part of a wider £2.6 bn investment in cyber and legacy IT. The Government is reviewing the Computer Misuse Act and has introduced the National Security Bill, which may help to strengthen the UK’s response to cyber threats from hostile states. It has also said it is willing to use cyber operations alongside its diplomatic, economic and military activities.
