The Iron are unbeaten in their last nine outings and just one point away from the 50-point figure widely considered the tally needed to avoid relegation.
With five games left of the season and just two points separating the club and the top half of the table, there is now an air of optimism at Glanford Park.
But for all the positive thoughts ahead of next season, Knill wants his side to maintain focus for the rest of the campaign.
"We still have five games to play and some others have six - so we still need some more points," he said.
"But after a difficult first half to the season, we have put ourselves in a good position. We have hit form at the right time.
"We are now nine games unbeaten and I want to see us try and win our last five games. We have a good squad now and the confidence is good.
"I was always confident we would score, but Exeter are fighting for their lives and often looked dangerous themselves pushing forward.
"It was good for us to keep another clean sheet, helped by some good saves by Sam Slocombe who is a young keeper developing really well and anxious to carry on learning."
Paul Tisdale, the Grecians boss, said the Iron had looked dangerous as he was left to face the likelihood of relegation.
"We had other chances to have won the game - but to be fair so too did Scunthorpe, it always looked like they might score," he said.
"We know the position we are in, but it's not over until it's over. We have just got to keep going and try to win the next game."
