President Trump met with his top national security advisers on Wednesday, along with energy industry leaders and top confidants, to discuss the cybersecurity threats facing the nation's electric grid.

Trump met with long-time head of the National Security Agency, General Keith Alexander, homeland security adviser Thomas Bossert, former New York City Mayor Rudy Guiliani, and "energy sector leaders" to discuss "energy sector resilience and cybersecurity," industry parlance for how to guard against hackers looking to take down the grid, according to a statement from the White House.

"President Trump thanked the participants in the meeting for their efforts and underscored the importance of a continuing public and private partnership to effectively combat threats against the energy sector, particularly the power grid," the White House statement read.

The Energy Department is using a public-private group created during the Obama administration to keep the communication channels open between the utility industry and government if there is a serious threat of attack to the grid. The partnership had been on high alert during the 2015 attack on Ukraine's power grid, which was significantly crippled by a cyberattack, and left tens of thousands without power for several hours.

The White House meeting comes a week after a congressionally-chartered grid reliability watchdog, the North American Electric Reliability Corporation, said in a report that the number of threats targeting the nation's grid are increasing.

On Thursday, the Federal Energy Regulatory Commission, the nation's top energy regulator, will convene an all-day conference to discuss the NERC report's findings.

"The 2015 and 2016 cyber-attacks on the electric grid in Ukraine are examples of how cyber systems used to operate and maintain interconnected networks, unless adequately protected, may be vulnerable to cyber-attack," a conference agenda read. "Cybersecurity continues to be a rapidly evolving risk to the Bulk Power System."

Representatives from the European Union, Mexico and Canada will address the forum, in addition to energy and utility trade groups and state regulators.

Energy Secretary Rick Perry told House appropriators on Tuesday that a major Energy Department grid study due out next week will address cybersecurity concerns, in addition to examining the state of the nation's power plants and overall grid reliability.

Bossert, who attended Wednesday's meeting with the president, will travel to Israel next week, where he will address a major cybersecurity conference, Cyber Week 2017, in Tel Aviv, organizers said in a press release.
