Secdir review of LISP Impact draft-saucez-lisp-impact-04.txt Do not be alarmed. I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. A new way of handling routing information has been defined in IETF documents about the Locator/Identifier Separation Protocol (LISP). The draft under discussion here elaborates on the possible consequences of widespread use of LISP. The draft punts on security considerations and refers to previous documents describing threats to LISP and how LISP uses cryptography for protecting the integrity of its messages. It seems to me that if the purported impact of LISP is to "scale the Internet", then its impact on security should be a major part of the equation. Will it make routing information more or less vulnerable malicious manipulation? How will it affect the stability of a network that is under constant threat of attack? I don't feel that the draft can achieve its purpose without addressing security. Hilarie PS. I was very disappointed to realize that this was not a draft about my favorite programming language.
