I have been tasked with configuring an IIS7 server to accept TLS 1.0 HTTPS connections only.

I have come up with the following list of cipher suites which I have deduced are TLS 1.0.

TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA
TLS_DHE_DSS_WITH_AES_128_CBC_SHA
TLS_DHE_DSS_WITH_AES_256_CBC_SHA
TLS_RSA_WITH_3DES_EDE_CBC_SHA
TLS_RSA_WITH_AES_128_CBC_SHA
TLS_RSA_WITH_AES_256_CBC_SHA

I have put that list in the box in the following policy: Computer Configuration | Administrative Templates | Network | SSL Configuration Settings | SSL Cipher Suite Order

Is that sufficient? Are any of the suites in my list not TLS 1.0? Are there any other TLS 1.0 suites supported by IIS7 that aren't in the list?

The server, by the way, is Windows Server 2008 R2.

Thanks

I have set up my Postfix, with TLS/SSL, correctly. Every test on the machine itself (with telnet) runs fine. However, when I want to access the server from somewhere else, it fails. So port 587 and the rest is blocked for some reason, but I don't really know where. >>> More
