Preparing Windows systems

Safeguard for Privileged Passwords supports Windows systems. For more information, see How to: Configure Windows Assets in Safeguard.

NOTE: Microsoft has started hardening DCOM servers which may change your configuration decisions. For more information, see https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-26414 and https://support.microsoft.com/en-us/topic/kb5004442-manage-changes-for-windows-dcom-server-security-feature-bypass-cve-2021-26414-f1400b52-c141-43d2-941e-37ed901c769c.

To prepare Windows systems for Safeguard for Privileged Passwords

  1. Create a service account on the asset and assign it a password:

    • Directory Configuration

      If the Windows system is joined to a domain that will be managed in Safeguard for Privileged Passwords, you can use a directory account, such as a Microsoft Active Directory account to manage the asset. Enable the Password Never Expires option; once you add the asset to Safeguard for Privileged Passwords, you can have the service account password auto-managed to keep it secure.

      -OR-

    • Local Configuration

      If the Windows system is not joined to a domain, then use a local service account that has been granted sufficient permissions.

  2. Grant the service account sufficient permissions to change account permissions to allow changing account passwords. For more information, see Minimum required permissions for Windows assets.

  3. Configure the system's firewall to allow the following predefined incoming rules:

    • Windows Management Instrumentation (DCOM-In)

    • Windows Management Instrumentation (WMI-In)

    • NetLogon Service (NP-In)

    These rules allow incoming traffic on TCP port 135 and TCP SMB 445, respectively.

  4. Ensure the following ports are accessible:

    • Port 389 is LDAP for connections. LDAP port 389 connections are used for Active Directory Asset Discovery and Directory Account Discovery.

    • Port 445 SMB is used to perform password check and changes.
    • In some cases, RPC ephemeral ports are required to be accessible for Safeguard for Privileged Passwords to perform Service Discovery on the Windows platform (for example, Windows Server 2019 requires the ports, however Windows Server 2012 does not). For more information, see Service overview and network port requirements for Windows.

  5. Change the local security policy:

    Before Safeguard for Privileged Passwords can reset local account passwords on Windows systems, using a service account that is a non-built-in administrator, you must change the local security policy to disable the User Account Control (UAC) Admin Approval Mode (Run all administrators in Admin Approval Mode) option. For more information, see Change password or SSH key fails.

For additional information on ports, see Safeguard ports.

Preparing WinRM systems

Safeguard for Privileged Passwords supports Windows Remote Management (WinRM) systems.

To prepare Windows Remote Management (WinRM) systems for Safeguard for Privileged Passwords

  1. The initial configuration requirements for WinRM depend on whether or not you are using SSL.

    • For SSL (this is when USE SSL Encryption and Verify SSL Certificate are enabled for the asset):

      1. You need to manually add a CA signed certificate to the asset:

        IMPORTANT: You will need to upload the CA certificate to Safeguard.

        On the asset, the certificate should be installed in the LocalMachine\My store and the CA should be in the LocalMachine\TrustedRoots store. If you use an intermediate that should be in the LocalMachine\Intermediate store.

        Ensure the following requirements are met for the certificate:

        • CN must match the hostname of the asset.

        • CRL must be present and resolvable.

        • Server Authentication enhanced key usage is required.

        1. The HTTPS listener needs to be registered in WinRM using the following command: winrm create winrm/config/Listener?Address=*+transport=HTTPS '@{Hostname="<hostname>";CertificateThumbprint="<thumbprint>"}'

        2. Use the following command to set the certificate: winrm set winrm/config/service '@{CertificateThumbprint="<TUMBPRINT"}'

        3. Open port 5986 in the firewall.

        4. Restart the Windows Remoting service.

    • For non-SSL:

      1. On the asset, run the following command: Enable-PSRemoting -Force.

  2. Create a service account on the asset and assign it a password:

    • Directory Configuration

      If the Windows system is joined to a domain that will be managed in Safeguard for Privileged Passwords, you can use a directory account, such as a Microsoft Active Directory account to manage the asset. Enable the Password Never Expires option; once you add the asset to Safeguard for Privileged Passwords, you can have the service account password auto-managed to keep it secure.

      -OR-

    • Local Configuration

      If the Windows system is not joined to a domain, then use a local service account that has been granted sufficient permissions.

  3. Grant the service account sufficient permissions to change account permissions to allow changing account passwords. For more information, see Minimum required permissions for Windows assets.

Preparing Windows SSH systems

Safeguard for Privileged Passwords supports Windows SSH systems. Windows SSH uses port 22 on the platform.

Safeguard for Privileged Passwords requires that C:\Windows\System32\cmd.exe be configured as the default shell for SSH (for more information, see OpenSSH Server configuration for Windows Server and Windows).

OpenSSH on Windows 8

The OpenSSH port on Windows 8 has server-side limitations on command execution. Password operations may appear to run more slowly because commands do not return until the timeout expires, even if the command has already completed on the server. You may need to tune the Connection Timeout (CommandTimeout) when running TestConnection, ChangePassword, and CheckPassword in order to allow these password operations enough time to run while still allowing enough time to avoid timeouts for other conditions specific to your network.

To prepare Windows SSH systems for Safeguard for Privileged Passwords

  1. Ensure the SSH server service is running.

  2. Create a service account on the asset and assign it a password:

    • Directory Configuration

      If the Windows SSH system is joined to a domain that will be managed in Safeguard for Privileged Passwords, you can use a directory account, such as a Microsoft Active Directory account to manage the asset. Enable the Password Never Expires option; once you add the asset to Safeguard for Privileged Passwords, you can have the service account password auto-managed to keep it secure.

      -OR-

    • Local Configuration

      If the Windows SSH system is not joined to a domain, then use a local service account that has been granted sufficient permissions.

      IMPORTANT: A local account does not have the access necessary to discover services running as domain accounts, so if a local account is used, Safeguard for Privileged Passwords will only discover and update services running as local accounts, and domain account dependencies will not be updated.

  3. Ensure the service account is added to the local Administrator's group to allow change password permissions. For more information, see Minimum required permissions for Windows assets.

Minimum required permissions for Windows assets

The following minimum permissions are required for Windows assets to perform directory password management and sessions management tasks using Windows Management Instrumentation (WMI).

NOTE: Microsoft has started hardening DCOM servers which may change your configuration decisions. For more information, see https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2021-26414 and https://support.microsoft.com/en-us/topic/kb5004442-manage-changes-for-windows-dcom-server-security-feature-bypass-cve-2021-26414-f1400b52-c141-43d2-941e-37ed901c769c.
