The Edinburgh coach issued his directive after watching his side hit back strongly in the wake of a poor first half.
"We showed tremendous character after the interval, when we scored 17 points and they scored 12," he said. "We had allowed Munster to pick up too much early momentum, which put us on the back foot and made it hard for us to get width on our defence.
"Our defence coach, Omar Mouneimne, has only had a week with the team and I have absolutely no doubt we will sort out that problem. We will go through the review of this game and, once we've put that to bed, our focus will turn to the Dragons."
Having soaked up a pile of pressure, the visitors snatched the lead in the 11th minute with an angled penalty by Piers Francis. But his strike spurred Munster into attacking action and hesitation in defence allowed full-back Dennis Hurley to squeeze over in the corner. The marking looked sloppy again just two minutes later when breakaway forward James Coughlan galloped in for their second touchdown, goaled by Ian Keatley who added a penalty from directly in front of the posts midway through the half.
Francis replied in identical style to keep Edinburgh in the picture, but their troubles began to mount again when winger Lee Jones was yellow-carded for a mid-air challenge on Coughlan. Then James Cronin rumbled over for Munster's third score, converted by Keatley.
Edinburgh looked much more slick after the restart and their efforts were rewarded when Nick De Luca jinked over for a fine try, Francis adding the extras.
Munster's response was again fast and clinical as Ivan Dineen made sure of the bonus point for the home side.
Substitute Harry Leonard cut the gap to 11 with a penalty, only for JJ Hanrahan to snuff out any chance of a salvage act by scoring another Munster touchdown, slotting the kick himself.
There was still time for Jones to score for Edinburgh, Leonard converting from wide.
