Theres lots of things you can do around potential wormholes. Build massive space stations with many many gun turrets, mine the crap out of the area, set up sensor arrays to probe inside the wormholes, set up gunships around the hole, have fleets of fighters ready to fly into the worm hole before anything comes through, prepare Confed's fleets to be able to hussle to any of the systems that show signs of bug activity, hurl massive asteroids into the holes as they open. THey may be able to send in fighters by the dozens but it appears they can only send in one cap ship at a time, so a prepared defense should be able to handle them, just like in the WCM, when the Kilrathi fleet stupidly jumped in one ship at time, to be demolished by the firepower of Tolwyn's fleet.
