	Title		: Security Framework for Provider Provisioned Virtual 
                          Private Networks

This draft addresses security aspects pertaining to Provider 
Provisioned Virtual Private Networks (PPVPNs). We first describe the 
security threats that are relevant in the context of PPVPNs, and the 
defensive techniques that can be used to combat those threats. We 
consider security issues deriving both from malicious behavior of 
anyone and from negligent or incorrect behavior of the providers. We 
also describe how these security attacks should be detected and 
reported. We then discuss the possible user requirements in terms of 
security in a PPVPN service. These user requirements translate into 
corresponding requirements for the providers. In addition, the 
provider may have additional requirements to make its network 
infrastructure secure and meet the VPN customerĘs expectations. 
Finally, we define how these user requirements apply to specific 
PPVPN technologies, namely RFC2547 PPVPNs, Virtual Router PPVPNs, 
IPSec VPNs, and Layer 2 PPVPNs.

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.
