The order is expected to commission several different reviews of the government's offensive and defensive cyber capabilities, according to one of the sources and a third briefed on a draft of the order that circulated last week.

The move follows a presidential campaign that was dominated by running storylines related to cyber security, including the hacking and subsequent leaking of Democratic emails as part of what U.S. intelligence agencies determined was a wide-ranging influence operation intended to help Trump win the White House and denigrate his challenger, Democrat Hillary Clinton.

For months Trump refused to accept the conclusions of the agencies that Russia was responsible, before stating at a press conference on January 11 that, "as far as hacking I think it was Russia."

In his answer, Trump, then the president-elect, pivoted to say that "we also get hacked by other countries, and other people" while vowing to launch a government-wide review of vulnerabilities to cyber attacks.

The order is expected to also initiate a audit of several federal agencies' cyber capabilities, seek input on how to improve protections for critical infrastructure, and review government efforts to attract and train a technically sophisticated workforce, according to two of the sources briefed on the draft, which was first published by the Washington Post.

The draft order would also seek ways to give the private sector incentives to adopt strong security measures.
