Setting up a secure (SSL) connection

To improve security of remote operations from a Device Manager - Storage Navigator SVP to a storage system, you can set up Secure Sockets Layer (SSL) encrypted communication. By setting SSL encryption, the Device Manager - Storage Navigator User ID and Password are encrypted.

• Setting up SSL communications

  Before you enable SSL encryption, you must create a private key and a public key to establish a secure communication session.

To enable SSL, you must create a keypair consisting of a public and a private key on the management client. The instructions use Windows 8.1 as an example.

After creating a private key and public key, obtain a signed public key certificate file. You can use any of these methods to obtain a signed certificate file.

• Create a certificate by self-signing. See Obtaining a self-signed certificate .
• Obtain a certificate from the certificate authority that is used by your company.
• Request an official certificate from an SSL certificate authority. See Obtaining a signed and trusted certificate.

Procedure

1. In the maintenance utility Menu navigation tree, click System Management.

   

2. Click Select Cipher Suite.

3. Select the type of communication to use between the management client and the storage system. The selections change the encryption level. Higher encryption provides better security but the communication speed is slower.

   • TLS_RSA_WITH_AES_128_CBC_SHA (Prioritize Transmission Speed). This selection provides higher communication speed and lower security.
   • TLS_RSA_WITH_AES_128_CBC_SHA256 (Prioritize Security). This selection provides higher security and lower communication speed.

  When you use encrypted SSL communications to manage your storage system, you can select the desired cipher suite, update a signed certificate, and return an updated certificate to default.

The following notes provide additional information about updating a signed certificate.

• While the service processor certificate is being updated, tasks that are being run or scheduled to run on Device Manager - Storage Navigator are not executed.
• Certificates for RMI communication are updated asynchronously. The process takes about two minutes.
• If the service processor certificate is updated while Ops Center Administrator or Hitachi Command Suite is being set up, the setup operation will fail.
• Updating the SSL certificate might change the system drastically and may lead to service processor failure. Therefore take sufficient care to consider the content of the certificate and private key to be set.
• After the certificate update is complete, depending on the environment, the service processor can take 30 to 60 minutes to restart.

When the message "There is a problem with this website's security certificate." is displayed, click Continue to this website (not recommended).

When you are using encrypted SSL communications to connect to the storage system, the browser displays a warning message if the security certificate is not issued by a trusted certificate authority. This warning message also appears when the IP address or host name specified in the URL does not match the CN listed in the security certificate.

If this warning message starts to appear after an update of the storage management software, check to see if the SSL certificate returned to the default. If the SSL certificate has returned to the default, install the certificate file that was backed up when the storage management software was updated.
