title: What's the difference between RASP, WAF and IDPS?
body: <p>What is the difference between:</p>
  
  <ol>
  <li>Runtime Application Self Protection (RASP)</li>
  <li>Web Application Firewalls (WAF)</li>
  <li>Intrusion Detection and Prevention Systems (IDPS)</li>
  </ol>
  
  <p>Especially the difference between IDPS and RASP is kind of vague to me. For example, I'm currently working on <a href="http://appsensor.org" rel="nofollow noreferrer">OWASP AppSensor</a> and they describe themselves as: "intrusion detection and automated response". </p>
  
  <p>I would assume then that AppSensor is a IDPS. But when I go and read what RASP means I'm more inclined to believe that AppSensor is a RASP. </p>
  
  <p>Can anyone explain the difference to me (and perhaps many others), preferably in plain English. </p>
