The Nationalelf went down 2-1 to the Azzurri at the National Stadium in Warsaw, thanks to a brace from Manchester City striker Mario Balotelli.
"We are no longer mourning the loss against Italy," Bild quotes Low as saying. "We have moved on from Euro 2012.
"It's not easy to start a qualification campaign again after a major tournament. We are still missing a few things and lack a bit of stability.
"It's a good thing that our flaws come to the fore now, though. We now know what we have to work on."
Low also reflected on Germany's success in international competitions over the past few years.
"We have made some huge steps forward in the past six years," he said. "The steps we make can obviously no longer be as big as before, though, now we've reached a certain level.
"We are not yet thinking about the World Cup itself at the moment. We are all in agreement that the only thing that matters for now is the qualification campaign."
Germany began their 2014 World Cup qualifying campaign with successive victories over the Faroe Islands and Austria this month.
