UK telecommunications companies could face fines of up to ten percent of their turnover or £100,000 ($133,140) a day if they fail to tighten security in their networks under the nation’s new legislation.

The government said that the proposed Telecommunications (Security) Bill, put forward on Tuesday, is designed to improve certain standards of the UK’s 5G and full-fiber networks, and to remove the threat of high-risk vendors.

“This will be a significant step to protect the UK from hostile cyber activity by state actors or criminals,” the Department of Culture, Media, and Sport said in a statement. “Over the past two years the government has attributed a range of cyber-attacks to Russia and China, as well as North Korea and Iranian actors.”

According to the department’s secretary Oliver Dowden, the bill “will give the UK one of the toughest telecoms security regimes in the world and allow us to take the action necessary to protect our networks.” (RT)
