The review began on Friday night, after an intruder entered the White House, reflecting major lapse in this most secured building of the US.
Obama, who was not inside the building when the incident happened, was briefed about it Friday night and subsequently over the weekend.
"It (review) will include a variety of things, including the positioning of tactical and non-tactical assets inside and outside the fence line. It will include a review of technical or physical security enhancements that may be necessary to improve security at the White House." White House Press Secretary Josh Earnest told reporters at his daily news conference.

"He did indicate his family lives in the White House. So, he is obviously concerned by the incident that occurred on Friday evening," he said.
"Senior Secret Service officials who are responsible for conducting this review are carrying it out with a sense of urgency. This is something that they are pursuing urgently, and I know that this is a review that it began Friday night," he added.
