What would Donald Trump do about cybersecurity if elected president? His statements so far have been a little vague. Until now.

On Monday, he gave some specifics on how he'd approach protecting the government and private industry from the threat of hackers.

"To truly make America safe, we truly have to make cybersecurity a major priority," Trump said in his speech at an event hosted by Retired American Warriors, where about 250 retired veterans sat in the audience, according to CBS News.

Saying he'd request a "thorough review" of the US's current cybersecurity capabilities, Trump cited the state-sponsored hacking attacks from Russia, China and North Korea as the nation's top concern. He also listed major hacks and data breaches that have affected departments of the US government like the Office of Personnel Management, as well as private companies like JPMorgan Chase.

The comments come on the heels of statements Trump made at the first presidential debate with opponent Hillary Clinton last week. While saying the US needs to be better at cybersecurity, Trump also questioned whether Russia was truly responsible for hacking the Democratic National Committee.

"I mean, it could be Russia, but it could also be China," Trump said at the debate. "It could also be lots of other people. It also could be somebody sitting on their bed that weighs 400 pounds, okay?"

Trump's comments were in response to Clinton's statements about cybersecurity. "There's no doubt now that Russia has used cyberattacks against all kinds of organizations in our country and I am deeply concerned about this," Clinton said.

She went on to chide Trump for praising Russian president Vladimir Putin, even though Russian cyberspies were responsible for hacking the DNC.
