LISP Threats Analysis
draft-ietf-lisp-threats-06.txt
Abstract
This document discusses potential security concerns with the Locator/
Identifier Separation Protocol (LISP) if deployed in the Internet and
proposes a set of recommendations to mitigate the identified threats
and to reach a level of security equivalent to what is observed in
the Internet today (i.e., without LISP). By following the
recommendations of this draft a LISP deployment can achieve a
security level that is comparable to the existing Internet
architecture.
