As part of our regular commitment to reviewing RFEs, we have re-reviewed this RFE and its status is maintained as Uncommitted Candidate. However, we would like to note some clarifications with regard to how the desired inbound behaviour can already be achieved:
In IIBv10:
If you don't set up any restricitons then TLSv1, TLSv1.1 or TLS1.2 will be accepted.
If you specifically disable the TLSv1 algorithm in java.security.file, then TLSv1 will fail, but TLSv1.1 and TLSv1.2 will succeed. The error you will receive for TLSv1 is "javax.net.ssl.SSLHandshakeException: No appropriate protocol, may be no appropriate cipher suite specified or protocols are deactivated"
If you set specifically then set the protocol on the request node to use the disabled version (TLSv1), then this will also fail.
If you change the protocol on the request node to be one that accepts a range of possibilities such as "SSL_TLSv2", then this will work again because TLSv1.1 or TLSv1.2 are options, but SSLv3 and TLSv1 will still be disabled as requested.
The default protocol is "TLS", which means TLSv1.0. However, this can be changed to be any TLS version by setting "com.ibm.jsse2.overrideDefaultTLS=true". So combining this with the above options gives the desired outcome expressed in the RFE.
We will continue to monitor this RFE for further comments and in particular we note that for outbound bevahiour and ease of administering the current settings there is more we could do in this area.
Thanks for raising this RFE. We agree this would make a great enhancement for IIB. Status is updated to Uncommitted Candidate.
