  Introduction and Description of Talk:

  Note: Due to a series of speaker cancelations, our Electronic Commerce
  meeting (http://www.unigroup.org/unigroup-9811.html) is moved to

  designed for the purposes of providing Network Access Security and Network
  Access Monitoring.  At our September meeting, we will discuss some popular
  security related tools and explain how they work and the purpose they serve.
