The report is likely to be released tomorrow by Senate Permanent Select Committee on Intelligence.
White House Press Secretary Josh Earnest said US President Barack Obama believes that the use of those interrogation tactics were unwarranted.
"It did not enhance national security interest of the United States of America," he said.
Meanwhile, security of American assets and personnel around the globe has been beefed up.
Warren said guidelines in this regard were issued on Friday.
The White House said that the Obama administration has been focused on this for the past several months.
"The administration has been, for months, preparing for the release of this report. There (are) some indications that the release of the report could lead to a greater risk that is posed to US facilities and individuals all around the world," Earnest said.
Earnest said: "The President, on his first or second day in office, took the steps using executive action to put an end to the tactics that are described in the report."
He said Obama believes it is important to release the report, so that people understand exactly what transpired.
"There are obviously gonna be some limits about what can be said, given the classified nature of the programme. But because of the scrupulous work of the committee and the administration and the intelligence community in particular, we have declassified as much of that report as we can," he added.
However, a 500-page redacted summary is expected to be released soon by Senator Dianne Feinstein, chairwoman of the Senate Intelligence Committee.
It is expected to contain new information about techniques used by CIA when interrogating terror susects in the years after the 9/11 attacks.
