The Australia international had not featured in a Barclays Premier League game for Brian McDermott's side since the 4-2 defeat at Chelsea on August 22 but had very little to do.
He was recalled for the enthralling Capital One Cup tie with Arsenal as the Gunners came from behind to win 7-5 and came back into the McDermott's league side following an injury to first-choice Alex McCarthy last weekend.
Federici, 27, shipped 14 goals in his four previous outings this season and was delighted to keep Norwich at bay.
"It is good to be back, it has been a tough time for me at the minute but it is good to be back in the team and the boys worked really hard today, defensively we were very solid and deserved a clean sheet," he told Reading FC Player.
"It was a good test, they are a good team and as I said our boys were solid which we have been lacking in the last few games in particular so it was nice for everyone to get a clean sheet.
"It is a good feeling being back in the team and a good feeling coming off with a clean sheet."
Federici, who made headlines for the wrong reasons when his girlfriend lambasted Reading officials for initially dropping him from the side, felt the Royals did enough to pick up their first league win of the season but is already looking ahead to the clash with high-flying Everton next weekend.
He said: "We had a few half-chances and maybe could have nicked all three points but at the end of the day it is something to build on and we look forward to the next game.
"We always look forward to the next game and Everton are a team very much in form at the minute but I think for all the fans who watch the game when you come to the Madejski Stadium it is a tough game for them."
In a game of little quality and few chances Norwich striker Grant Holt missed the best chance when he mis-timed a header in the latter stages.
Garath McCleary, Sean Morrison and Jobi McAnuff all had chances for Reading but Norwich held on to keep their first clean sheet on the road for 38 Premier League games.
Canaries boss Chris Hughton was pleased with his side's effort at the back but admits it is hard for a team like Norwich to strike a balance at both ends of the pitch.
"We had to defend a lot of crosses, a lot of corners and a lot of free-kicks but that aspect of the game we did well," he said.
"Sometimes you do have to sacrifice a little bit, the best teams can be good at both ends - we know where we are and if we want to be competitive and be in every game we have to make sure we are tight as a unit."
The goalless draw saw Norwich secure their eighth point from their last four league games after a poor run of form had seen them drop perilously close to the bottom three.
Hughton believes the three back-to-back defeats to Newcastle, Liverpool and Chelsea sparked his team into life.
"It is a reaction from the poor result we had at Chelsea, which was two poor results on the spin," he said.
"They have shown a great reaction and we have consistency in the team now - that always helps.
"One good result sometimes can lead into another and another and probably that is what is happening at the moment."
