什么是正确的JBoss EAP 6.0.1密码套件配置,用于缓解Logjam / weakdh.org?

由于最近几天logjam和网站https://weakdh.org/(Logjam:Diffie-Hellman在实践中失败)的关注,我决定强化我的JBoss EAP 6.0.1系统上的SSL配置这里描述:

13.2.5。 SSL连接器参考:https://access.redhat.com/documentation/en-US/JBoss_Enterprise_Application_Platform/6/html/Administration_and_Configuration_Guide/SSL_Connector_Reference1.html

交叉参考此处:http://www.coderanch.com/t/613062/JBoss/configuring-SSL-Https-Jboss

我的standalone.xml的相关部分包含在下面的混淆格式中:

     <connector name="https" protocol="HTTP/1.1" scheme="https" 
    socket-binding="https" secure="true">  
    <ssl  
     key-alias="**********"  
     password="**********"  
     certificate-key-file="/var/**********/**********.jks"  
     protocol="TLSv1.2"  
     cipher-suite="TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384,TLS_DHE_RSA_WITH_AES_128_GCM_SHA256,TLS_DHE_DSS_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_AES_128_SHA256,TLS_ECDHE_ECDSA_WITH_AES_128_SHA256,TLS_ECDHE_RSA_WITH_AES_128_SHA,TLS_ECDHE_ECDSA_WITH_AES_128_SHA,TLS_ECDHE_RSA_WITH_AE_256_SHA384,TLS_ECDHE_ECDSA_WITH_AES_256_SHA384,TLS_ECDHE_RSA_WITH_AES_256_SHA,TLS_ECDHE_ECDSA_WITH_AES_256_SHA,TLS_DHE_RSA_WITH_AES_128_SHA256,TLS_DHE_RSA_WITH_AES_128_SHA,TLS_DHE_DSS_WITH_AES_128_SHA256,TLS_DHE_RSA_WITH_AES_256_SHA256,TLS_DHE_DSS_WITH_AES_256_SHA,TLS_DHE_RSA_WITH_AES_256_SHA"  
     />  
    </connector> 

协议限制正在起作用,但据我所知,密码套件属性没有效果。我已将列表缩减为仅两个套件,但JBoss在端口8443上返回的列表始终相同。 我已经针对Qualys SSL Labs对系统进行了测试,并且返回的密码套件列表包含了许多未包含在我的列表中的密码。

 Cipher Suites (sorted by strength; the server has no preference)
 TLS_RSA_WITH_RC4_128_MD5 (0x4)   WEAK     128
 TLS_RSA_WITH_RC4_128_SHA (0x5)   WEAK     128
 TLS_RSA_WITH_AES_128_CBC_SHA (0x2f)     128
 TLS_DHE_RSA_WITH_AES_128_CBC_SHA (0x33)   DH 768 bits (p: 96, g: 96, Ys: 96)   FS   INSECURE     128
 TLS_ECDHE_RSA_WITH_RC4_128_SHA (0xc011)   WEAK     128
 TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA (0xc013)   ECDH 571 bits (eq. 15360 bits RSA)   FS     128
 TLS_RSA_WITH_3DES_EDE_CBC_SHA (0xa)     112
 TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA (0x16)   DH 768 bits (p: 96, g: 96, Ys: 96)   FS   INSECURE     112
 TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA (0xc012)   ECDH 571 bits (eq. 15360 bits RSA)   FS     112

更新: 我尝试通过CLI调整配置,希望它可以做一些不同的事情:

 /subsystem=web/connector=https/ssl=configuration/:write-attribute(name=cipher-suite, value="TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA")

然后输出(也对应于新的standalone.xml):

 [standalone@localhost:9999 /] /subsystem=web/connector=https/ssl=configuration/:read-resource(recursive=true,proxies=false,include-runtime=true,include-defaults=true)
 {
      "outcome" => "success",
      "result" => {
           "ca-certificate-file" => undefined,
           "ca-certificate-password" => undefined,
           "ca-revocation-url" => undefined,
           "certificate-file" => undefined,
           "certificate-key-file" => "/var/xxxx/xxxx-xx/xxxx.jks",
           "cipher-suite" => "TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA",
           "key-alias" => "xxxx",
           "keystore-type" => undefined,
           "name" => undefined,
           "password" => "****",
           "protocol" => "TLSv1.2",
           "session-cache-size" => undefined,
           "session-timeout" => undefined,
           "truststore-type" => undefined,
           "verify-client" => "false",
           "verify-depth" => undefined
      },
      "response-headers" => {"process-state" => "reload-required"}
 }

但使用此命令的nmap:

 nmap -p 8443 -A --script ssh-hostkey,ssh2-enum-algos,sshv1,ssl-cert,ssl-date,ssl-enum-ciphers,ssl-google-cert-catalog,ssl-heartbleed,ssl-known-key,sslv2 xxxx.de

坚持认为其他密码套件仍处于活动状态:

显然,这里有一些关于这个主题的指导: https://access.redhat.com/solutions/661193(在EAP 6中禁用弱SSL密码) 唉,我无法访问,因为RedHat的政策似乎将应用服务器和互联网的安全性置于付费墙之后。叹。

任何人都可以确认这个问题,更好的是,为解决方案提供建议。如果没有将其置于反向代理(我的计划B)之后,是否有人有工作配置?谢谢。

由于JBoss邮件列表和Stackoverflow工作人员都没有任何反馈意见,因此我将这个问题归结为JBoss版本中的一个错误。我通过升级到Wildfly 8.2并使用提供的说明进行配置来解决它,它按预期工作。

我想这是一个臭名昭着的,不可否认的是旧版本的服务器。对于后代,这是wildfly的SSL侦听器的配置:

 <https-listener name="https" socket-binding="https" security-
  realm="SSLRealm"      
  enabled-protocols="TLSv1.2"     
  enabled-cipher-suites="TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, etc."/>

相应的安全领域可能如下所示:

<security-realm name="SSLRealm"> 
    <server-identities> 
      <ssl > 
        <keystore
     path="/var/mysite/ssl/mysite.jks"
     keystore-password="******"
     alias="mysite"
     /> 
      </ssl> 
    </server-identities> 
  </security-realm>

我们正在使用jboss-6.1.0并通过添加

解决了这个问题
SSLHonorCipherOrder="On" 
ciphers="SSL_RSA_WITH_RC4_128_MD5,SSL_RSA_WITH_RC4_128_SHA"

server.xml ,即

<Connector protocol="HTTP/1.1" SSLEnabled="true" 
           port="8443" address="${jboss.bind.address}"
           scheme="https" secure="true" clientAuth="false" 
           keystoreFile="${jboss.server.home.dir}/conf/XXXX"
           keystorePass="XXXX" sslProtocol = "TLS"     
           SSLHonorCipherOrder="On" 
           ciphers="SSL_RSA_WITH_RC4_128_MD5,SSL_RSA_WITH_RC4_128_SHA" />

我认为长期解决方案是升级到最新的JBOSS AS之一。

使用https连接器中的ssl元素的以下属性:

dfgrp = originaldf.groupby(['industry','sub_industry'])

for industry, sub_industry in dfgrp:
    if 'specialty finance' in industry:
        print(industry)
        print(sub_industry)
