To ensure continued access to the VMware Aria Automation cluster nodes, you must manage the life cycle of the account passwords for the VMware Aria Automation appliances.

In VMware Cloud Foundation, SDDC Manager manages the life cycle of critical accounts used by and integrated within the system. SDDC Manager provides the ability to rotate, update, or remediate component passwords. Unlike the password rotation, which generates a randomized password, the password update allows you to provide the password that you want for the particular account.

If a password expires, you must reset the password in the component. After you reset the password, you must remediate the password. Password remediation updates the new password in the SDDC Manager database.

To resolve any errors that might have occurred during password rotation or updates, you must use password remediation. Password remediation synchronizes the password of the component account stored in VMware Aria Automation with the updated password.

Password Policies for VMware Aria Automation

Within VMware Aria Automation, you can enforce password polices for access through the virtual appliance console and SSH. You can configure these password policies by using the pluggable authentication module (PAM) that is part of the operating system of the virtual appliance. The password policies apply only to local user accounts.

Password Expiration Policy for VMware Aria Automation

You manage the password expiration policy on a per-user basis. You can modify the configuration for a user to refine the settings and adhere to the policies and regulatory standards of your organization. The default configuration is shown in the following table.

Password Complexity Policy for VMware Aria Automation

You manage the password complexity policy by using the /etc/pam.d/system-password file. You can edit the file and add or modify the configuration to refine the settings. The /etc/pam.d/system-password file does not contain default password complexity settings. You must configure the settings according to the following table, using your values to adhere to the policies of your organization and regulatory standards.

Design Implication

PCA-VAA-SEC-019

Change the VMware Aria Automationroot password on a recurring or event-initiated schedule by using the SDDC Manager user interface or API.

  • By default, the password for the VMware Aria Automationroot account expires every 365 days.

  • When VMware Aria Automation is deployed into a VMware Cloud Foundation environment in VMware Aria Suite Lifecycle, the root password is managed from the SDDC Manager user interface or API, not from the vRealize Suite Lifecycle Manager.

By using SDDC Manager, you manage the password change or automate password rotation schedule for the VMware Aria Automationroot account in accordance with your organizational policies and regulatory standards.
