WebSphere TLS Clearing issues

Is TLS v1.2 supported in WebSphere Full Profile 7.0, 8.0, 8.5? What's minimum fix pack?

Answer: TLsv1.2 Suppport on V7.0.0.23 on wards TLsv1.2 Support on 8.0.0.3 onwards and 8.5.0.0.

• TLS v1.2 supported in WebSphere with following JDK version. 7.0.0.23 comes JDK version as follows and TLSv1.2 supported SDK 6
  (32-bit) pap3260sr10fp1-20120321_01(SR10 FP1)
  (64-bit) pap6460sr10fp1-20120321_01(SR10 FP1)​

• 8.0.0.3 comes with JDK version follows and TLSv1.2 supported
  SDK 6.0.1 (J9 2.6)
  (32-bit) pap3260_26sr1fp1-20120309_01(SR1 FP1)
  (64-bit) pap6460_26sr1fp1-20120309_01(SR1 FP1)

• 8.5 comes with JDK version follows and TLSv1.2 supported
  SDK 6.0.1 (J9 2.6)
  (32-bit) pap3260_26sr2ifix-20120419_02(SR2+IV19661)
  (64-bit) pap6460_26sr2ifix-20120419_02(SR2+IV19661)

This change allows TLS 1.1 and 1.2 to be configured at the webserver plugin in 8.0 and later on distributed platforms.

• TLS 1.1 and 1.2 is not supported on zOS at this time.
• Despite this APAR being listed in 7.0 fixpacks, 7.0 does not support TLs1.1 and TLS1.2 due to the use of GSKit V7.

WAS

Click Security > SSL configurations CellDefaultSSLsetting , NodedefaultSSLsetting and any other SSLConfig

1. Select each SSL Configuration described above, then click Quality of protection (QoP) settings under Additional Properties.

2. On the **Quality of protection (QoP)** settings panel, select TLSv1.2 from the pull-down list in the box named Protocol. change the protocol to TLSV1.2

3. update ssl.client.props
This must be done for each **ssl.client.props** file under the following directories:
For Node example WAS_install\profiles\AppSrv01\properties
For DMGR example WAS_install\profiles\Dmgr01\properties

 **com.ibm.ssl.protocol=TLSv1.2**

4. stopNode.sh && stopManager.sh 

5. startManager.sh

6. syncNode.sh dmgrhostname dmgrsoapport -username userid -password password

7. startNode.sh

8. Click Protocol : openssl s_client -connect webspherehostname:9443 -tls1_2

WEB

update httpd.conf

VirtualHost
SSLProtocolEnable TLSv12
SSLProtocolDisable SSLv2 SSLv3 TLSv10 TLSv11

Plg

Why do I receive a GSK_ERROR_SOCKET_CLOSED (gsk rc = 420) error, when WebSphere Application Server and IBM HTTP Server are configured to use TLSv1.2? Answer: you need to have StrictSecurity="true" in the plugin-cfg.xml for TLSv1.2 to work. More details see the following link

2. ikeyman을 이용한 인증서 발급

• 발급된 인증서가 있는 경우 해당 인증서 사용

3. 콘솔상에서 가상호스트 추가 작업

• 관리콘솔 접속 해당 위치의 추가된 포트 정보 등록
  
  위치: 가상 호스트 > default_host > 호스트 별명
  
  내용: 443 Port 를 기존 가상호스트 에 등록

4. WebServer Restart
