            8) Security                 -  Steve Crocker/TIS

   The work of the IETF is performed by subcommittees known as Working
   Groups.  There are currently more than 40 of these.  Working Groups
   tend to have a narrow focus and a lifetime bounded by completion of a
   specific task, although there are exceptions.  The IETF is a major
   source of proposed protocol standards, for final approval by the IAB.
   The IETF meets quarterly and extensive minutes of the plenary
   proceedings as well as reports from each of the working groups are
   issued by the IAB Secretariat at the Corporation for National
   Research Initiatives.

4.  The Internet Research Task Force

   To promote research in networking and the development of new
   technology, the IAB established the Internet Research Task Force
   (IRTF).

   In the area of network protocols, the distinction between research
   and engineering is not always clear, so there will sometimes be
   overlap between activities of the IETF and the IRTF.  There is, in
   fact, considerable overlap in membership between the two groups.
   This overlap is regarded as vital for cross-fertilization and
   technology transfer.  In general, the distinction between research

   and engineering is one of viewpoint and sometimes (but not always)
   time-frame.  The IRTF is generally more concerned with understanding
   than with products or standard protocols, although specific
   experimental protocols may have to be developed, implemented and
   tested in order to gain understanding.

   The IRTF is a community of network researchers, generally with an
   Internet focus.  The work of the IRTF is governed by its Internet
   Research Steering Group (IRSG).  The chairman of the IRTF and IRSG is
   David Clark.  The IRTF is organized into a number of Research Groups
   (RGs) whose chairs of these are appointed by the chairman of the
   IRSG. The RG chairs and others selected by the IRSG chairman serve on
   the IRSG.  These groups typically have 10 to 20 members, and each
   covers a broad area of research, pursuing specific topics, determined
   at least in part by the interests of the members and by
   recommendations of the IAB.

   The current members of the IRSG are as follows:

            David Clark/MIT LCS     -   Chairman
            Robert Braden/USC-ISI   -   End-to-End Services
            Douglas Comer/PURDUE    -   Member-at-Large
            Deborah Estrin/USC      -   Autonomous Networks
            Stephen Kent/BBN        -   Privacy and Security
            Keith Lantz/Consultant  -   Collaboration Technology
            David Mills/UDEL        -   Member-at-Large

5.  The Near-term Agenda of the IAB

   There are seven principal foci of IAB attention for the period 1989 -
   1990:

      1) Operational Stability
      2) User Services
      3) OSI Coexistence
      4) Testbed Facilities
      5) Security
      6) Getting Big
      7) Getting Fast

   Operational stability of the Internet is a critical concern for all
   of its users.  Better tools are needed for gathering operational
   data, to assist in fault isolation at all levels and to analyze the
   performance of the system.  Opportunities abound for increased
   cooperation among the operators of the various Internet components
   [RFC 1109].  Specific, known problems should be dealt with, such as
   implementation deficiencies in some versions of the BIND domain name
   service resolver software.  To the extent that the existing Exterior

   Gateway Protocol (EGP) is only able to support limited topologies,
   constraints on topological linkages and allowed transit paths should
   be enforced until a more general Inter-Autonomous System routing
   protocol can be specified.  Flexiblity for Internet implementation
   would be enhanced by the adoption of a common internal gateway
   routing protocol by all vendors of internet routers.  A major effort
   is recommended to achieve conformance to the Host Requirements RFCs
   which were published in the fourth quarter of calendar 1989.

   Among the most needed user services, the White Pages (electronic
   mailbox directory service) seems the most pressing.  Efforts should
   be focused on widespread deployment of these capabilities in the
   Internet by mid-1990.  The IAB recommends that existing white pages
   facilities and newer ones, such as X.500, be populated with up-to-
   date user information and made accessible to Internet users and users
   of other systems (e.g., commercial email carriers) linked to the
   Internet. Connectivity with commercial electronic mail carriers
   should be vigorously pursued, as well as links to other network
   research communities in Europe and the rest of the world.

   Development and deployment of privacy-enhanced electronic mail
   software should be accelerated in 1990 after release of public domain
   software implementing the private electronic mail standards [RFC
   1113, RFC 1114 and RFC 1115].  Finally, support for new or enhanced
   applications such as computer-based conferencing, multi-media
   messaging and collaboration support systems should be developed.

   The National Network Testbed (NNT) resources planned by the FRICC
   should be applied to support conferencing and collaboration protocol
   development and application experiments and to support multi-vendor
   router interoperability testing (e.g., interior and exterior routing,
   network management, multi-protocol routing and forwarding).

   With respect to growth in the Internet, architectural attention
   should be focused on scaling the system to hundreds of millions of
   users and hundreds of thousands of networks.  The naming, addressing,
   routing and navigation problems occasioned by such growth should be
   analyzed.  Similarly, research should be carried out on analyzing the
   limits to the existing Internet architecture, including the ability
   of the present protocol suite to cope with speeds in the gigabit
   range and latencies varying from microseconds to seconds in duration.

   The Internet should be positioned to support the use of OSI protocols
   by the end of 1990 or sooner, if possible.  Provision for multi-
   protocol routing and forwarding among diverse vendor routes is one
   important goal.  Introduction of X.400 electronic mail services and
   interoperation with RFC 822/SMTP [RFC 822, RFC 821, RFC 987, RFC
   1026, and RFC 1148] should be targeted for 1990 as well.  These

   efforts will need to work in conjunction with the White Pages
   services mentioned above.  The IETF, in particular, should establish
   liaison with various OSI working groups (e.g., at NIST, RARE, Network
   Management Forum) to coordinate planning for OSI introduction into
   the Internet and to facilitate registration of information pertinent
   to the Internet with the various authorities responsible for OSI
   standards in the United States.

   Finally, with respect to security, a concerted effort should be made
   to develop guidance and documentation for Internet host managers
   concerning configuration management, known security problems (and
   their solutions) and software and technologies available to provide
   enhanced security and privacy to the users of the Internet.
