exchange 2010应用环境

四台前端服务器，两台位于DMZ区，两台位于办公网环境，办公网和DMZ的服务器做了NLB负载均衡，操作系统为windows server 2008 r2.
目前前端https绑定的是企业自颁发的sha1证书，加密套件为系统默认.
默认开启了RC4
使用了非安全的协议SSL_V2.0及SSL_V3.0

更改需求

将DMZ区两台服务器IIS证书替换为公网的sha256证书
关闭RC4
禁用SSL_V2.0及SSL_V3.0,启用TLS_V1.2，TLS_V1.1,TLS_V1.0(默认已启用)协议
更新加密套件的优先顺序，配置Forward secrecy

操作

购买证书

由于公司有统一人员负责证书事宜，只提供了相关的域名，最终拿到手的是证一个私钥(private.key)及一个cer(20170928.cer)证书文件。需要将cer证书文件转为pfx类型的证书，然后导入服务器-个人区域。

*
```
openssl.exe pkcs12 -in 20170928.cer -inkey private.key -export -out server.pfx


输入两次证书密码，就可以导出证书文件server.pfx
```
* 需要安装完整的证书链，否则证书不能正常的使用。
绑定证书

iis管理器选择刚刚导入的证书，绑定到https

禁用RC4

将以下代码保存为rc4.reg并导入系统

 Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers\RC4 128/128]


"Enabled"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers\RC4 40/128]


"Enabled"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Ciphers\RC4 56/128]


"Enabled"=dword:00000000

禁用ssl,启用tls

将以下代码保存为ssl.reg并导入系统

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 2.0]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 2.0\Server]

"Enabled"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 3.0]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 3.0\Client]

"Enabled"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 3.0\Server]

"Enabled"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Client]

"Enabled"=dword:00000001

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1\Server]

"Enabled"=dword:00000001

"DisabledByDefault"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client]

"Enabled"=dword:00000001

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server]

"Enabled"=dword:00000001

"DisabledByDefault"=dword:00000000

更新加密套件

可以运行gpedit.smc，选择计算机-管理模板-网络-ssl密码套件启用并将$cipherSuitesOrder的值填入，参数之间用英文状态下的逗号隔开



以下为powershell脚本
