I don't speak MIB particularly well, but I think that the Security Considerations section needs to be expanded. In particular, there are more entries that need to be read-protected as well, most notably tcpEStatsDataSndNxt -- if I know that and know (or can guess) the connection 4-tuple, I can hijack the connection. --Steve Bellovin, http://www.research.att.com/~smb Full text of "Firewalls" book now at http://www.wilyhacker.com _______________________________________________ tsvwg mailing list tsvwg@ietf.org http://www1.ietf.org/mailman/listinfo/tsvwg
