Noughts

In the game of Noughts, each player takes a turn to place a nought on the board (see below). Each new nought goes into a new square. The winner is the first person to place three noughts in a row. Is it possible for either the first player or the second player, to always win? (Assume that each player plays to win and plays as well as is possible.) If so, what is the winning strategy? If not, why not?
