I'd like to throw in here that asteroid based mass drivers and hacking are not   
   the only methods of attack at this point. With the need from maintenance   
   craft, a fake maintenance vehicle (not super easy to accomplish since there   
   would be protective    
   measures but feasible) could slowly work it's way through the network and   
   place small explosive charges on sensitive systems.   
      
   Since we're talking about solar sails, a laser could be used to push the   
   sensors out of orbit or into each other or other humorous actions.   
      
   Another tactic could be small "suicide" drones. They'd be launched at the net   
   from different directions and attack the platforms at close range, possibly   
   with lasers or short ranged mini missiles. The simpler the sensor net   
   elements, the less this type    
   of attack makes sense. The more capabilities the net's elements have, the   
   easier it is to make the suicide drones cheaper than the net. The important   
   part is to make them disposable.   
      
   Another type of attack is spoofing the net's communications and creating a   
   denial of service attack with powerful radio transmitters.
