A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Dynamic Host Configuration Working Group of the IETF.

	Title		: Dynamic Host Configuration Protocol for IPv4 (DHCPv4) Threat Analysis
	Author(s)	: R. Hibbs, et al.
	Filename	: draft-ietf-dhc-v4-threat-analysis-03.txt
	Pages		: 20

DHCPv4 (RFC 2131) is a stable, widely used protocol for 
configuration of host systems in a TCP/IPv4 network.  It did not 
provide for authentication of clients and servers, nor did it 
provide for data confidentiality.  This is reflected in the original 
"Security Considerations" section of RFC 2131, which identifies a 
few threats and leaves development of any defenses against those 
threats to future work.  In about 1995, DHCP security began to 
attract attention from the Internet community, eventually resulting 
in the publication of RFC 3118 in 2001.  Although RFC 3118 was a 
mandatory prerequisite for the DHCPv4 Reconfigure Extension, RFC 
3203, it has had no known usage by any commercial or private 
implementation since its adoption.  The DHC Working Group adopted a 
work item for 2003 to review and modify or replace RFC 3118 to 
afford a workable, easily deployed security mechanism for DHCPv4.  
This memo provides a threat analysis of the Dynamic Host 
Configuration Protocol for Ipv4 (DHCPv4) for use both as RFC 2131 
advances from Draft Standard to Full Standard and to support our 
chartered work improving the acceptance and deployment of RFC 3118.

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.
