The replies here are excellent (as usual!) but they are mostly tactics, not strategy. Establish a strategy first, then select tactics to achieve that strategy. Nailing down the right strategy helps you 1) discover threats you didn't think of and 2) avoid wasting resources on poor tactics. It takes a little more up-front effort but the payoff is worth it.

A good example of a valid strategy (followed by tactics) is Listening to Katrina. Use it as a starting place, not gospel, then decide on YOUR strategy and follow up with appropriate tactics.
