Abstract

   This document outlines procedures that may be used to test network
   equipment for well known vulnerabilities. This information is being
   provided to the Internet community in the hopes that network
   operators will adopt the procedures outlined as part of their normal
   practice during the procurement process and as part of ongoing
   security evaluation procedures.   It is also hoped that vendors will
   adopt these procedures as part of their quality assurance procedures.
   The overall goals are increased awareness of and an reduction in the
   number of well known exposures in deployed network equipment.

2. Vendor Recommended Vulnerability Detection Procedure

   o  Download the most recent version of Nessus.

   o  Burn it onto a CD.

   o  Trow the CD at the Device Under Test (DUT).

   o  Observe the results.

3. Security Considerations

   o  The primary instructions assume intelligence on the part of the
      tester.

   o  While the intent of these instructions is to assist network
      operators and vendors in assessing the security posture of devices
      that they, respectively, produce and deploy, detailed,
      easy-to-follow instructions listing methods of detecting (and
      possibly exploiting) vulnerabilities in networked devices could be
      misused by hackers to do Bad Things.  This could be an argument
      (made, for instance, by your legal department) for not publishing
      detailed, easy to use instructions.  However, see the assumption
      in the previous item...then ask yourself "how bright is your
      average hacker/script kiddie" and "do these recommendations
      *really* tell the bright hackers anything they didn't already know
      ?"

   o  It is possible, though not likely, that widespread adoption of the
      procedures outlined in this memo will result in large sums of
      money flowing to (previously) poor, overworked open-source
      software developers, thus altering their development priorities in
      ways that result in fewer vulnerabilities being reported in the
      products of certain vendors.
