RE: Turing off SSLv2 and SSLv3 support

Just an update to close the string I started.

We turned off SSLv2 and SSLv3 yesterday on our iSeries . So far no issues. I also found out that it is recommended to turn off SSLv2 and SSLv3 on desktop browsers and in desktop java configuration. Which I did on my own PC and have not had any issues there either

Hi Mike:

We just went through this on our PCI environment . We use a free service from qualys ssl labs https://www.ssllabs.com/ssltest/ This online service tests the ssl certificates and server configuration of the server in question. After ssllabs completes its assessment the report will show a handshake simulation section (along with a ton of other stuff) showing the results of the ssl handshake of various platforms and browsers.

You are correct older browsers like IE 6 will not be able to by default connect with your server. I do think there is a setting in IE 6 that enables TLS 1.0 but its not checked/enabled by default.

Hope this helps.

Jim

Did anyone encounter any issues after turning off SSLv2 and SSLv3 support on their system? Our PCI scan this quarter says it has to be disabled or we will not be considered in compliance. I believe the only issue with doing this is that some users with very old browsers will not be able to negotiate an secure connection.

Thanks
