Title : Quarantine Model Overview for IPv6 Network Security

In the current Internet, a site is often secured by firewall, which
filters harmful traffic from outside at the border of the site. This
'Border Defense Model', provides only a single line of defence and
hinders the deployment of many next-generation Internet applications
and services.
This memo surveys the security issues of the 'Border Defense Model',
and proposes a network architecture 'Quarantine Model', to provide a
better security model and promote various end-to-end Internet usages.
In our 'Quarantine Model', nodes shareing an Enterprise network
network are connected to separate logical networks according to their
security privilege level and community of interest. A different
security policy is implemented on each logical network segment using
the multiple security-related techniques, such as filtering,
authentication, and encryption. This 'Compartmentalized' framework
provides a better depth of network defenes and additional flexibility
to our 'Quarantine Model'.
This memo enumerates requirements and issues for this architecture.
However, it is beyond the scope of this document to propose specific
implementations or protocols.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
