Pg 5, Line 152 – “In of itself, this document….” Did you mean “By itself”
Pg 5, Line 99 – ” Unfortunately there is no provisioning…” should be “provision”
Pg 10, Line 307 – “referencable” should be “referenceable”
Pg 15, Line 465 – not clear to me why you define SSL 3.0 ciphersuites here and in Table 4 since the remainder of this
section only defines mechanisms using TLS
Pg 16, Line 493 & Line 509; Pg 17, Line 532 & Line 548 – “A transport ciphersuite of either TLS_RSA_WITH_AES_256_CBC_SHA or
SSL_RSA_WITH_AES_256_CBC_SHA” . Why isn’t AES_128 encryption supported? Even the Gov’ts Suite B requirements state
AES_128 is adequate to support encryption of info at the Secret classification level.
I note the normative policies defined in Appendix B are also restricted to use of TLS and AES_256. I suggest AES_128
should be the base requirement. Also I think you need to either: 1) clearly indicate SSL is not supported or 2) add text
to indicate SSL 3.0 may be used as an alternative to TLS.
Pg 18, 7.0 – From earlier discussion, I was under the impression use of password authentication was only being
recommended when used with a TLS encrypted, server authenticated, channel. That seems to be lost in this version. If it
is your intent to allow initiator password authentication without a TLS channel, then additional security considerations
should be added to indicate the potential dangers.
Pg 18, 7.2 – Shouldn’t there be a note that this policy should only be used with a SERVER_TLS policy to prevent clear-
text transmission of a password? At a minimum you should add a security considerations statement.
Pg 18, 7.3 – As above, if you assume SERVER_TLS when using password msg authN then the rationale for supporting this is
weak. This digest algorithm protects against cut&paste replay attacks and slows down password guessing attacks. Those
aren’t really an issue if you’re inside a TLS channel. If your intent is too support this outside a TLS channel, then
you should add that this is the only recommended method for doing initiator password authN over an unencrypted channel.
Appendix A – Also defines allowed SSL 3.0 ciphersuites, but the spec doesn’t seem to allow SSL use?
