7. Security Considerations

   Consult [1]'s Section 11 for a discussion of security issues.

   In addition:

   o  The dataTiming option (Section 2) may be used to expose private
      network topology.  Accordingly, an administrator may wish to
      choose to disable this option except at the ingress/egress points
      for its administrative domain.

   o  The hold4Endpoint option (Section 3) may be used to facilitate
      denial-of-service attacks.  Accordingly, an administrator may wish
      to impose administrative limits on this attribute (e.g., always
      require that the "dataTiming" option also be present with a
      short-lived "noLaterThan" attribute).
