Deschamps replaced Laurent Blanc as national boss after the latter opted not to stay on in the aftermath of his side's quarter-final exit at the hands of eventual winners Italy.
Blanc had done much in his two-year stint to heal the rifts caused during a tumultuous World Cup campaign under Raymond Domenech but saw a lot of his good work undone in Poland and Ukraine.
The French Football Federation have already opened disciplinary proceedings against four members of the squad - Samir Nasri, Hatem Ben Arfa, Jeremy Menez and Yann M'Vila - for various alleged indiscretions at Euro 2012.
On the field, there were also disappointments, finishing second in the their group behind England after defeat to Sweden in their last group game.
Speaking at his unveiling, Deschamps said: "It will be difficult, but we will do everything to achieve our goal.
"The first important thing is to qualify for the 2014 World Cup. I want a team that has control, is effective in both areas of the pitch and is exposed on the least number of occasions.
"The team must be clear in their desire and strong in determination.
"There will be a guiding principle, but with different options. Whatever the system, a team must be able to come forward and cause problems for the opponent.
"After that, everything depends of course on the opponent, but in terms of personal investments, there are obligations."
Blanc and Deschamps were France team-mates when they won the World Cup in 1998, but Deschamps has not sought a detailed analysis of the job in front of him from his predecessor.
"I actually talked to him and it was a friendly discussion, but he needs to recover," said Deschamps.
"I do not see the need to make an inventory of what went well or not (under him). While it could be rewarding, I do not support that approach. I succeeded him with great respect and I salute the work done by his staff.
"I am part of continuity but there are things I may do differently."
Deschamps has only signed a two-year deal with the FFF, taking him to the end of the 2014 World Cup in Brazil, but he was not expecting a longer deal.
Asked if he had wanted a four-year offer, he said: "No. Even if the president gave me four years, if I failed I would be gone."
