The United States is prepared to go on the offensive in cyberspace to ensure adversaries know there is a price to pay for hacks, network intrusions and other types of attacks.

President Donald Trump signed a new National Cyber Strategy on Thursday, calling for a more aggressive response to the growing online threat posed by other countries, terrorist groups and criminal organizations.

"My administration will use all available means to keep America safe from cyber threats," Trump said in a statement, calling the new strategy an "important step."

Other key officials called the new strategy an important and badly needed change.

"We're not just on defense," National Security Adviser John Bolton told reporters. "We're going to do a lot of things offensively, and I think our adversaries need to know that."

"Our hands are not tied as they were in the Obama administration," he added.

Strategy effective immediately

The strategy, which takes effect immediately, is being billed by the Trump administration as the first "fully articulated" cyberstrategy in 15 years, providing direction to various departments and agencies on how best to protect their data as well as the private data of millions of Americans.

The internet has brought prosperity and productivity to American lives and those across the world, Bolton said.

"We must do more to ensure it is secure and remains an engine of American growth," he added.

He said the ultimate goal is "to create the structures of deterrence that will demonstrate to adversaries that the cost of their engaging in operations against us is higher than they want to bear." (VOA)
