Title : Service Provider Infrastructure Security
Author(s) : D. Lewis, et al.
Filename : draft-lewis-infrastructure-security-00.txt
Pages : 20

This RFC defines best current practices for implementing Service
Provider network infrastructure protection for network elements.
This RFC complements and extends RFC 2267 and RFC 3704. RFC 2267
provides guidelines for filtering traffic on the ingress to service
provider networks. RFC 3704 expands the recommendations described in
RFC 2267 to address operational filtering guidelines for single and
multi-homed environments. The focus of those RFCs is on filtering
ingress packets ingress, regardless of destination, if those packets
are have spoofed source address or fall within "reserved" address
space. Deployment of RFCs 2267 and 3704 has limited the effects of
denial of service attacks by dropping ingress packets with spoofed
source addresses, which in turn offers other benefits by ensuring
that packets coming into a network originate from validly allocated
and consistent sources.
This document focuses solely on traffic destined to the network
infrastructure itself to protect the network from denial of service
and other attacks. This document presents techniques that, together
with network edge ingress filtering and RFC 2267 and RFC 3704, create
a layered approach for infrastructure protection.
This document does not present recommendations for protocol validation (i.e. "sanity checking") nor does it address guidelines
for general security configuration.

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
