title: Neural network and IDS
body: <p>I am trying to get a grasp on the efficiency of neural networks over other artificial intelligence algorithms for use in intrusion detection systems.  Most of the literature I’m reading isn’t giving a good comparison of neural networks compared to other IDS's.</p>
  
  <p>Do they work better (detect more true attacks and less false positives)? Are they more or less efficient?</p>
  
  <p>Another question is how new is NN in IDS environments? Are they used widely, is it old news?</p>
