Mark Warburton's side have been exceptional defensively in recent weeks.
The 25-year-old has featured in each of the Light Blues' last five Scottish Championship games, and has helped Mark Warburton's side keep a mightily impressive record in that time, as Liam Buchanan's goal for Livingston is the only strike that Rangers have conceded during those games.
And with the side going on to win each of those five fixtures, Kiernan admitted that the defence is simply focused on providing the attacking players with the opportunity to win the game, by keeping the opposition at bay.
"No goals against is pleasing for the team. Our main objective in the game is to build a platform to let the boys up top do their magic and score goals," he said, as reported by the Record.
"We've got 13 games left now and we know our target. We just need to perform and, whether it is pretty or not, simply win matches.
"We have to see the finishing line. It's our objective this season to win promotion and we can see the end of the season coming. We need to maintain our concentration and focus."
Although the wins against Dumbarton and Livingston were emphatic, the victories over Morton, Falkirk and Raith were much more narrow, thus highlighting the good work that Kiernan and his colleagues have done to keep the club at the top of the table.
As the former Wigan man alluded to, the end of the campaign is in sight. And while an eight-point gap may have some already believing that promotion is assured, Kiernan appears determined to ensure that no member of the squad relaxes until the title race is wrapped up.
Certainly, if Rangers continue to keep the goals out, then they should have no problem making sure it is they that are going up as champions.
