Wassall was speaking following the sacking of manager Paul Clement this week.
The former academy director was named as manager until the end of the season following the sacking of former boss Paul Clement on Monday.
That dismissal came as a shock to many, with the Rams currently fifth in the table and just five points away from the top two Middlesbrough and Hull City.
Chairman Mel Morris referred to the need to play in the “Derby way” in the statement following his sacking, and when questioned what that is, Wassall says it is simple.
"The Derby way is simple," Wassall told BBC Sport.
"We want to be hard to beat and make the iPro in to a fortress, but we also want to try to play attractive football and score lots of goals. That's easier said than done.
"I will manage the team how I want to manage the team. I will do it my way. We are in great position. I will not try to be different to anybody else; I will just do it my way."
For now, Wassall will be hoping he can turn around the alarming run of form that is threatening to derail the Rams' push for promotion this season.
They are currently eight games without a win in the Championship, their last victory coming in the 2-0 win over Fulham all the way back on Boxing Day.
The key may be Derby finding their goalscoring boots once again, as they have not managed to score two goals in a league game since the end of December.
