Reference: User Administration menu

Use TanOS to manage user accounts on the Tanium appliance. Users with the tanadmin role can manage two types of user accounts:

  • Use the TanOS User Management menu to manage TanOS system users. These user accounts can access the TanOS console, but not the Tanium™ Console. This includes the predefined TanOS users tanadmin, tancopy, and tanuser. TanOS system users are local to each appliance, users are not shared across appliances. For more information on the predefined TanOS user accounts, see Configure user access (physical appliance) or Configure user access (virtual appliance).
  • Use the TanOS User Management menu to manage TanOS system users. These user accounts can access the TanOS console, but not the Tanium™ Console. This includes the predefined TanOS users tanadmin, tancopy, and tanuser. TanOS system users are local to each appliance, users are not shared across appliances. For more information on the predefined TanOS user accounts, see Configure user access.
  • Use the Local Tanium User Management menu to manage Tanium users who can access the Tanium Console through a web browser. These user accounts cannot access the TanOS console. TanOS hosts a local authentication service that you can use for Tanium Console user authentication. In addition, you can use your enterprise LDAP server to manage Tanium Console authentication. For details on using LDAP, see the Tanium Core Platform User Guide.

Change TanOS user passwords

The TanOS special users tanadmin and tanuser can make password-authenticated SSH connections to the TanOS console.

Change the tanadmin password

Use these steps to reset the password for the current tanadmin user. To change the password for another tanadmin user, see Manage system users.

  1. Sign in to the TanOS console as a user with the tanadmin role.
  2. Enter P and follow the prompts to change the password. ClosedView screen

After the password changes, you are signed out.

Reset the tanuser password

  1. Sign in to the TanOS console as a user with the tanadmin role.
  2. Enter C to go to the User Administration menu. ClosedView screen
  3. Enter U to go to the TanOS User Management menu. ClosedView screen
  4. Enter 3 to select the tanuser user. ClosedView screen
  5. Enter C to Change/Enable Password, and follow the prompts to reset the password. ClosedView screen

Manage SSH keys

The installation process generates a public/private SSH key pair for the tanadmin user. Use the SSH Key Management menu to perform the following functions:

  • Regenerate the key pair.
  • Generate keys for the other TanOS special users.
  • Add authorized keys to support inbound user connections.
  • View the public key so you can copy and paste it into other appliance configurations.

You can use ssh-copy-id to add an SSH public key to any TanOS user with the tanadmin role.

Before you begin

  • You must have an SSH client to sign in to the TanOS console and an SFTP client such as WinSCP to copy files to and from the appliance.
  • You must have an SSH key generator such as ssh-keygen to generate keys for the user.

Generate keys

  1. Sign in to the TanOS console as a user with the tanadmin role.
  2. Enter C to go to the User Administration menu. ClosedView screen
  3. Enter U to go to the TanOS User Management menu.

  5. Enter P to go to the Manage SSH Key Pair menu. ClosedView screen
  6. Enter G to generate a public/private key pair. ClosedView screen

Add authorized keys

  1. Use an SSH key generator such as ssh-keygen to generate a public/private key pair. Note:
    • Specify an RSA key with 2048 bits (such as ssh-keygen -t rsa -b 2048).
    • Specify a passphrase that is easy to remember.
    • Save the private key to a location that you can access when you set up your SFTP client.
  2. Copy all of the text in the public key file to the clipboard. If you use ssh-keygen, copy the contents of the .pub file that you created.

    In an SSH key exchange, the keys must match exactly.

  3. Sign in to the TanOS console as a user with the tanadmin role.
  4. Enter C to go to the User Administration menu.

Configure the local authentication service

You can use the local authentication service to set up Tanium Console user accounts for demo or testing purposes.

For best results, configure the Tanium Console to use an external LDAP server to authenticate Tanium users. For details, see the Tanium Core Platform User Guide. Additionally, if you plan to use the local authentication service with the Tanium LDAP Sync connector, you must use the following user filter in the LDAP Sync Connector configuration:

(&(objectClass=person)(uidNumber>=20000))

The Local Authentication Service menu is available only after you install the Tanium Server on the appliance.

Modify the local authentication service security policy

The local authentication service security policy has the following default settings.

Setting Factory Default Description
