The LDAP/AD page is used to configure the DXi4800 system to use the LDAPv3 protocol and connect to a remote server for the purpose of authenticating login credentials. The DXi4800 will assign permissions to the login based on the group membership in the LDAP server. Microsoft Active Directory (AD) can be configured to support LDAP and the DXi4800 can then connect to the AD server for the purposes of authenticating login credentials.

LDAP and AD Terms

Common Name (CN)

An attribute that is commonly used to distinguish items at the same (usually top) level in the LDAP hierarchy.

Example

The SysAdmin group would have cn=sysadmin.

Domain Component (DC)

The domain of the directory, which often identifies the organization or company.

Example

Mycompany.com would have a domain of dc=mycompany,dc=com.

Distinguished Name (DN)

A pathway that tells LDAP where information is stored in its directory. LDAP reads the pathway from right to left, with the farthest right components providing the domain of the directory and the farthest left component providing the information for which LDAP is looking.

Organizational Unit (OU)

A component used to organize information into a hierarchical structure. OUs can be used at multiple levels within the LDAP or AD directory, such as to act as a larger Group bucket that then holds individual group OUs.

Tasks

Use the LDAP/AD page to perform the following tasks:

  1. Select the Enable LDAP/AD check box to enable the Connection Settings and Search Strings tables.

  2. Enter the following Connection Settings information:

    Primary Server

The SSL/TLS page allows you to enable or disable SSL/TLS on the DXi4800. You can also install a new SSL certificate to replace the Quantum default SSL/TLS certificate.

To access the SSL/TLS page, on the Security page, click the SSL/TLS tab.

Additional Information

  • If you enable SSL/TLS see Server Authentication Warnings for important information about Web browser settings.

  • SSL/TLS is automatically enabled by default after a fresh installation of DXi software.

Tasks

Use the SSL/TLS page to perform the following tasks:

SSL (Secure Sockets Layer)/TLS (Transport Layer Security) is a protocol that provides security and privacy over the Internet by negotiating encryption keys before transmitting data between a client and a server.

To establish a secure connection, the DXi4800 must have an encryption key assigned to it by a Certification Authority in the form of a certificate file, private key file, and pass phrase. After you install these components, you can establish a secure connection using the SSL/TLS protocol. The DXi4800 comes with a Quantum default SSL/TLS certificate.

To enable or disable SSL/TLS:

  1. Under SSL/TLS Properties, select the Enable SSL/TLS option to enable SSL/TLS.

    2. Or select the Disable SSL/TLS option to disable SSL/TLS.

    Note: The default setting is disabled.

  2. Click Apply.

Enabling SSL/TLS with the default Quantum certificate allows you to securely communicate with the DXi4800 Web-based interface using SSL/TLS encryption. However, you may receive a warning from your Web browser and network security scanners stating that the server you are attempting to connect to does not match the server embedded within the certificate.

This is expected behavior because the default certificate can only be used for encryption and not server authentication. Quantum recommends the default Quantum certificate be replaced with your own official certificate specific to your DXi system. You can install your own custom certificate in order to take advantage of server authentication in addition to encrypted communication.

Suppress the server authentication warnings as you would for any site based on the browser you are using.

Caution: Quantum recommends that you ALWAYS confirm the correct URL before supressing server authentication warnings.

You can purchase and install your own custom SSL/TLS certificate in order to take advantage of server authentication in addition to encrypted communication on the DXi4800.

To install an SSL/TLS certificate:

  1. Under Certificate, click New.

    The Install New Certificate page displays.

  2. In the Certificate File box, type the location and filename of the new SSL/TLS certificate file.

    Or click Browse to browse the system and locate the SSL/TLS certificate file. The SSL/TLS certificate file must be named server.crt.

  3. Click Upload.
  4. Type your SSL/TLS private key and press Enter.

  5. Type your SSL/TLS passphrase and press Enter.

    A Successful Upload page displays stating that the SSL/TLS certificate file has been installed on the system.

  6. Click OK.

    The certificate displays in the Certificate section.

The Data Encryption page allows you to select the type of encryption to use for Replication, OST, and Accent data transfers. Data sent from the media server (OST/Accent) or source DXi (Replication) to the DXi can be encrypted using AES (Advanced Encryption Standard) encryption methods.

To access the Data Encryption page, on the Security page, click the Data Encryption tab.

Important Information

  • If TLS with AES 256 is selected, the factory installed certificates are inadequate for security. The factory installed certificates should be considered public domain and are provided only for convenience. You must install new certificates for secure encryption.

  • The DXi uses the TLS with AES 256 certificate authority as the arbiter of trust. To ensure the security of your data on the DXi blockpool, you must generate your own private certificate authority.

  • Certificates must contain the following key usage fields / extensions, (replace <<URI>> with the applicable URI)

basicConstraints = CA:FALSE

subjectKeyIdentifier = hash

authorityKeyIdentifier = keyid,issuer:always

keyUsage = critical, nonRepudiation, digitalSignature, keyEncipherment, keyAgreement

extendedKeyUsage = critical, serverAuth, clientAuth

crlDistributionPoints = URI:<<URI>>

subjectAltName=${ENV::BC_SAN}

  • Installing new certificates requires a reboot of the system.

How to: Certificate Generation Using a Certification Authority (CA)

 

Step 1: Generate Private Key

Generate a private key to be used for creating the Certificate Signing Request (CSR):

$ openssl genrsa -out key.pem 2048

 

Step 2: Generate Certificate Signing Request (CSR)

Generate a CSR using the private key. Ensure that the Common Name (CN) in the CSR matches the hostname of your server:

$ openssl req -new -key key.pem -out csr.pem -subj "/C=IN/ST=KA/L=bangalore/O=quantum/CN=server-1/emailAddress=test@quantum.com"

Note: The CSR includes the public key and information such as the server's hostname, organization, and country.

Note: Verify that the CN field corresponds to the hostname of the server.

 

Step 3: Submit CSR to the Certificate Authority (CA)

Provide the generated csr.pem file to your Certificate Authority for signing. The CA will issue a signed certificate (e.g., cert.pem) and may also provide intermediate certificates.

Full Certificate Chain Requirement:

  • The ROOT CA need to be combined with all intermediate certificates provided by the CA into a full certificate chain.

  • Example of a chained CA certificate file (cacert.pem):

    -----BEGIN CERTIFICATE-----

    ROOT CA cert

    -----END CERTIFICATE-----

    -----BEGIN CERTIFICATE-----

    SUB CA cert

    -----END CERTIFICATE-----

Note: The order of certificates in the chain can sometimes affect the validation process. Ensure the Root CA is at the top, followed by intermediate CAs in hierarchical order.

 

Step 4: Validate the Signed Certificate

Once you receive the signed certificate (cert.pem), verify it against the full CA certificate chain:

$ openssl verify -CAfile cacert.pem cert.pem

cert.pem: OK

Note: If validation fails, check that the full certificate chain is correct and in the appropriate order.

 

Step 5: Deploy the Certificates

Upload the following files to the server in TLS Certificates section:

1. Certificate File (Signed Certificate - cert.pem)

2. Private Key File (key.pem)

3. Certificate Authority File (Full Certificate Chain - cacert.pem)

 

Additional Notes:

Order of Certificates in cacert.pem:

  • The order can matter in some implementations. Ensure the Root CA is first, followed by intermediate CAs in order of hierarchy.

  • If validation fails, try reordering the certificates in cacert.pem and test again.

Common Errors:

  • Validation may fail if the full chain is incomplete

To enable or disable data encryption:

  1. Select an Encryption option in OST and Accent Data Transfer Encryption:

    None Data is not encrypted.
    Default AES 128 OST and Accent data is encrypted using AES 128-bit encryption.
    Default AES 256 OST and Accent is encrypted using AES 256-bit encryption.
    TLS with AES 256

    OST, Accent, and Replication data is encrypted using AES 256-bit encryption with Transport Layer Security (TLS).

    For replication, you must specify encryption settings when configuring the replication or failback targets. See Replication .

  2. If you selected the TLS with AES 256 encryption option, install the required TLS Certificate and key files on the DXi4800 system:

    • Certificate File
    • Private Key File
    • Certificate Authority File
    • Certificate Revocation List (Optional)

    OST Media Server with TLS Encryption

    The certificate and key files installed on the DXi4800 system must match the files on the OST media server. For more information on certificate and key files, see the OST Plug-in Installation Instructions.

    Replication with TLS Encryption

    To successfully use replication with TLS encryption, you must do the following:

    • Configure target DXi4800 with TLS Encryption.
    • Configure source DXi4800 with TLS Encryption (system reboot required).
    • Select TLS with AES 256 when configuring the target DXi4800. See Adding a Replication Target.

    The source DXi4800 key and target DXi4800 key do not need to match, but must meet the following criteria:

    • The target key must be signed by a certificate in the source key.
    • The source key must be signed by a certificate in the target key.

    To install a file, click the Browse button to browse the system and locate the file, and then click Open.

    Caution: Installing certificate files requires a system reboot immediately after the changes are applied. Wait for at least 15 minutes before logging back in.

    Note: You can install new certificate and key files at any time, as long as there are no active network connections between the server and the DXi4800.

  3. Click Apply. Changes made to the TLS Certificates will require a system reboot and the Save Changes dialog box appears.

    Select one of the following options.

    Option Description
    Defer Reboot

    Defers the system reboot. A Reboot Required alert message will appear in the GUI banner until the system is rebooted.

    Deferring a reboot is only recommended if additional system changes that require a reboot need to be made (Network, Application Environment, Data Encryption changes) or ingest (backup jobs) are currently in progress on the system.

    Note: Once a reboot is in a deferred state, the applied changes cannot be reset.
    Reboot Now

    Starts the system reboot. A system reboot can take up to 15 minutes.
    Cancel No reboot occurs and the Data Encryption page reappears. Changes made to the settings remain but are not applied. Click Reset to reset settings to their original state.

    Additional Information

    • To revert all network settings to the initial state and undo all changes, click the Reset button.
    • To clear all changes without saving them, click Reset. To remove user installed certificate and key files, click Restore Factory Defaults.

The Login Settings page allows Administrators to:

  • Set the system's inactivity timeout in minutes.

  • Enable and disable Multi-Factor Authentication (MFA).

Tasks

Use the controls on the Login Settings page to complete the following tasks:

To access the Login Settings page, on the Security tab, click on the Login Settings tab.

The Inactivity Timeout setting allows you to specify the inactivity timeout for the DXi4800 remote management console. The default timeout is 30 minutes.

When the remote management console is inactive for the time period specified, the user is automatically logged off and must log back on to continue. See Accessing Remote Management.

To specify the inactivity timeout for all system users:

  1. In the Inactivity Timeout box, enter the number of minutes of inactivity before a user is automatically logged off (1–600 minutes).
  2. Click Apply.

GUI Administrators use this feature to enable DXi MFA (Multi-Factor Authentication) feature for RBAC (Role-based Access Control) users. See Adding Users and Assigning Roles for instructions on adding RBAC users.

NOTES

  • For systems configured to use the LDAPv3 protocol and connect to a remote server for the purpose of authenticating login credentials, MFA rules apply to those users. See LDAP/AD.

  • SSH/CLI Service users (username: ServiceLogin) are not required to login with MFA credentials.

  • Downloading an authenticator program is the suggested method of working with MFA.

To enable the system to use MFA:

  1. Under OTP (One-time Password), check the Enable Multi-Factor Authentication box.

    Note: NTP must be enabled to enable the Time-based One-time password and enable MFA. See Date & Time.

  2. Click Apply.

    All users created on the Users page will need to set up and use MFA. See Set Up Multi-Factor Authentication.

After enabling MFA, when users are added in the system using the System > Security > Users page, at first login, they will need to set up their MFA:

  1. At the Login screen, type your Username and Password, and then click on Login.

    DXi Password Requirements

    Passwords must be between 8-64 characters, and must include at least one upper case (A-Z), one lowercase (a-z), one number (0-9), and one special character ( ` ~ ! @ # $ % ^ & * ( ) - _ = + [ ] { } \ | ; : ' " , . < > / ? space ).

    Note: Existing passwords for all users remain valid and are not subject to these requirements.

  2. The Login screen changes to display a QR code screen similar to the following image:

  3. Using your authenticator application, select your account for company use and either:

    • Scan the QR code.

    • Copy and paste or type the 32-character Shared Secret Code into your authenticator application.

    Your authenticator application generates a 6-digit One-time password code.

  4. On the Login screen still displaying the QR code, type the One-time password code in the Authentication code box, and then click Apply.

    You are logged on to your DXi system with your MFA code and the Home screen is displayed.

For subsequent logins after completing your MFA setup:

  1. At the Login screen, type your Username and Password, and then click on Login.

    The Login screen changes to display an Authentication code box.

  2. Using your Microsoft Authenticator application, select your company account and type the 6-digit One-time password code in the DXi Login screen Authentication code box, and then click Apply.

    You are logged on to your DXi system with your MFA code and the Home screen is displayed. This is now your regular login process.

Caution: Disabling MFA deletes all secret keys created for RBAC-setup users. When MFA is re-enabled, users will need to re-authenticate using the steps in Set Up Multi-Factor Authentication and Subsequent Logins After MFA Setup.

To disable MFA for all system users:

  1. Under OTP (One-time Password), un-check the Enable Multi-Factor Authentication box.

    A confirmation message displays, reminding you that disabling MFA for all users and the secret authentication key for each will be deleted from the system.

  2. Click Yes to continue or No if you need to leave MFA in place for the system.

If, for example, a user loses their phone containing the authenticator application and their account information, the GUI Administrator can delete the user's secret key. Under TOTP User Settings, click in the Username box under Delete user's secret key and enter the user's Username to remove the user's Shared Secret Code from the system.

Note: The terms Secret Key and Shared Secret Code refer to the same character string. The terms will be merged in a future release.

To remove a user's secret key:

  1. Under TOTP User Settings, type the user's Username in the Username box.

  2. Click on Delete secret key.

    A confirmation message is displayed.

  3. Click on Yes to confirm the deletion.

    Note: A system message on the screen confirms that the user's secret key has been deleted. At the user's next login to DXi , they must repeat the processes in Set Up Multi-Factor Authentication and Subsequent Logins After MFA Setup. They may also need to add their company account in Authenticator.

The Security Notice page allows you to specify a message that will appear to all users when logging on to the remote management console or the CLI (command line interface).

If a security notice message has been specified, the user must accept the message in order to begin using the system. If no security notice has been specified, the user can use the system immediately after logging on.

To access the Security Notice page, on the Security page, click Security Notice.

To add or update a security notice message, enter the message in the box and click Apply.

The Data-at-Rest page allows you to enable Data-at-Rest Encryption on the DXi4800 and manage security keys.

Note: The Data-at-Rest page displays only if the Data-at-Rest Encryption feature is supported on the DXi4800 and is licensed for use

Caution: After you enable Data-at-Rest Encryption, you cannot disable it or turn it off. Make sure to back up your passphrase and recovery files, as they may be required for future capacity expansion or in certain, rare hardware failure scenarios. See Managing Recovery Files.

To access the Data-at-Rest page, on the Security page, click the Data-at-Rest tab.

WARNING: This page takes a few minutes to update.

Tasks

Use the Data-at-Rest page to perform the following tasks:

The current status of Data-at-Rest Encryption can be Disabled (default) or Enabled. If it is enabled, all drives in the DXi4800 are securely encrypted and cannot be read if removed from the system.

Click Check Status to view detailed information about the status of Data-at-Rest Encryption and to see if the DXi4800 supports all requirements for enabling the feature.

When Data-at-Rest Encryption is enabled, all hard drives in the DXi4800 are paired to their respective RAID controllers using encryption keys. These keys are generated using a passphrase that you supply.

Caution: Make sure you are certain you want to enable Data-at-Rest Encryption before proceeding. After you enable Data-at-Rest Encryption, you cannot disable it or turn it off.

To enable Data-at-Rest Encryption:

  1. Verify that the system is in an optimal state:

    • All hardware statuses on the system are Normal. See Hardware.

      Caution: All storage arrays must show Normal condition. If any storage arrays are degraded, do not enable Data-at-Rest Encryption. See Details.

    • All outstanding administration alerts are deleted. See Admin Alerts.
    • All service tickets are closed. See Service Tickets.

  2. Under Enable Data-at-Rest Encryption, type a security passphrase in the Passphrase box.

    Caution: If you are re-enabling Data-at-Rest Encryption, you must enter the same passphrase that was used when encryption was originally enabled.

    The passphrase must meet all of the following requirements:

    • Must be 8–32 characters long.
    • Must contain at least 1 digit [0–9].
    • Must contain at least 1 uppercase letter [A–Z].
    • Must contain at least 1 lowercase letter [a–z].

    • Must contain at least 1 non-alphanumerical character, for example, ‘+’ or ‘@’.

      Note: An underscore [ _ ] is considered an alphanumeric character.

    • Must not contain a space, tab, single quote [‘], double quote [“], or dollar sign [$].
  3. Enter the passphrase again in the Confirm Passphrase box.
  4. Click Enable.

Data-at-Rest Encryption is now enabled, and all hard drives are secured so that, if they are removed from the DXi4800, they cannot be read using another system or device.

Be sure to record the passphrase in a safe location. You should also save a backup copy of the Data-at-Rest Recovery file. See Managing Recovery Files.

When Data-at-Rest Encryption is enabled, the system generates security keys based on the supplied passphrase. The DXi4800 maintains a copy of the security keys on the system, and they are accessed automatically as needed.

There are a few, rare situations which may require manual entry of the passphrase, such as performing a capacity expansion, or in certain hardware failure scenarios. The Data-at-Rest Recovery file is a password protected .xml file that contains an encryption key identifier and passphrase for the controller. The encryption key identifier provides the system serial number, product ID, and location for the controller.
