The Attorney General of the United Kingdom, Suella Breivman, in her speech stated the applicability of international law not only in the real world, but also in cyberspace. In her opinion, the principle of non-interference in the affairs of another country should allow States to take defensive cyber countermeasures.
This statement appeared against the background of cyberwarfare during a special operation in Ukraine. According to the Attorney General, the UK can legally impose sanctions, as well as cyber-countermeasures, provided that they are proportional to the attack of a hostile state.
“International law is important in cyberspace. If we do not establish rules there, if we do not have a clear framework for countering hostile actions in cyberspace, and if we do not ensure cybersecurity properly, then the consequences of cyber attacks will become much more dangerous for ordinary users,” said Suella Breivman.
