Remediate Hybrid Security Posture Assessments in Defender for Identity

In brief

The hybrid security posture assessments page now documents the assessment for privileged SaaS accounts outside identity-provider control, including its impact and implementation steps. Other edits update headings, formatting, metadata, and links.

What Defender admins need to know

Administrators can review exposed entities and, where applicable, move privileged access under identity-provider control, disable unnecessary app-native accounts, and apply SSO, MFA, Conditional Access, and lifecycle governance.

Remediate hybrid security posture assessments in Defender for Identity

This article lists all hybrid security posture assessments for Microsoft Defender for Identity.

Change password for Microsoft Entra seamless SSO account

The Change password for Microsoft Entra seamless SSO account assessment lists all Microsoft Entra seamless SSO computer accounts with password last set over 90 days ago.

User impact

Microsoft Entra seamless SSO automatically signs in users when they're using their corporate desktops that are connected to your corporate network. Seamless SSO provides your users with easy access to your cloud-based applications without using any other on-premises components. When setting up Microsoft Entra Seamless SSO, a computer account named AZUREADSSOACC is created in Active Directory. By default, the password for this Azure SSO computer account isn't automatically updated every 30 days. The AZUREADSSOACC account password functions as a shared secret between AD and Microsoft Entra, enabling Microsoft Entra to decrypt Kerberos tickets used in the seamless SSO process between Active Directory and Microsoft Entra ID. If an attacker gains control of this account, they can generate service tickets for the AZUREADSSOACC account on behalf of any user and impersonate any user within the Microsoft Entra tenant that has been synchronized from Active Directory.

Implementation

  1. Review the recommended action at https://security.microsoft.com/securescore?viewid=actions for Change password for Microsoft Entra seamless SSO account.account.

  2. Review the list of exposed entities to discover which of your Microsoft Entra SSO computer accounts have a password more than 90 days old.

Ensure no privileged SaaS app accounts exist outside of IdP control

The Ensure no privileged SaaS app accounts exist outside of IdP control assessment lists privileged accounts that are created and managed directly in SaaS applications instead of through the organization's identity provider.

User impact

Privileged local accounts in SaaS apps can bypass centralized identity controls, including single sign-on, multifactor authentication, Conditional Access, lifecycle governance, and security monitoring. If an attacker compromises one of these accounts, they may be able to sign in directly to the SaaS application and access sensitive data without triggering the protections applied to identities managed by the identity provider.

Implementation

  1. Review the recommended action in the Microsoft Defender portal for Ensure no privileged SaaS app accounts exist outside of IdP control.
  2. Review the list of exposed entities to identify privileged SaaS accounts that aren't managed by your identity provider.
  3. Migrate required privileged access to identities managed by the identity provider.
  4. Disable or remove app-native privileged accounts that are no longer required.
  5. Apply single sign-on, multifactor authentication, Conditional Access, and lifecycle governance to remaining privileged SaaS access.

Rotate password for Microsoft Entra Connect AD DS Connector account

Description

The Rotate password for Microsoft Entra Connect AD DS Connector account assessment lists all MSOL accounts in your organization with password last set over 90 days ago.

User impact

Smart attackers are likely to target Microsoft Entra Connect in on-premises environments, and for good reason. The Microsoft Entra Connect server can be a prime target, especially based on the permissions assigned to the AD DS Connector account (created in on-premises AD with the MSOL_ prefix).

It's important to change the password of MSOL accounts every 90 days to prevent attackers from allowing use of the high privileges that the connector account typically holds - replication permissions, reset password and so on.

Implementation

  1. Review the recommended action at Microsoft Secure Score actions for Rotate password for Microsoft Entra Connect AD DS Connector account.account.

  2. Review the list of exposed entities to discover which of your AD DS Connector accounts have a password more than 90 days old.

Remove unnecessary replication permissions for Microsoft Entra Connect AD DS Connector account

Smart attackers are likely to target Microsoft Entra Connect in on-premises environments, and for good reason. The Microsoft Entra Connect server can be a prime target, especially based on the permissions assigned to the AD DS Connector account (created in on-premises AD with the MSOL_ prefix). In the default 'express' installation of Microsoft Entra Connect, the connector service account is granted replication permissions, among others, to ensure proper synchronization. If Password Hash Sync (a feature that synchronizes password hashes from on-premises AD to Microsoft Entra ID) isn’t configured, it’s important to remove unnecessary permissions to minimize the potential attack surface.

Implementation

  1. Review the recommended action at https://security.microsoft.com/securescore?viewid=actions for Remove unnecessary replication permissions for Microsoft Entra Connect AD DS Connector account.account.

  2. Review the list of exposed entities to discover which of your AD DS Connector accounts have unnecessary replication permissions.

Remove unsafe permissions on sensitive Microsoft Entra Connect accounts

Description

Microsoft Entra Connect accounts like AD DS Connector account (also known as MSOL_) and Microsoft Entra Seamless Single Sign-On (SSO) computer account (AZUREADSSOACC) have powerful privileges, including replication and password reset rights. If these accounts are granted unsafe permissions, attackers could exploit them to gain unauthorized access, escalate privileges, or take control of hybrid identity infrastructure. This could lead to account takeovers, unauthorized directory modifications, and a broader compromise of both on-premises and cloud environments.

Implementation

  1. Review the recommended action at Microsoft Secure Score actions for Remove unsafe permissions on sensitive Microsoft Entra Connect accounts.accounts.

  2. Review the list of exposed entities to identify accounts with unsafe permissions. For example:

  3. For each exposed account, remove problematic permissions that allow unprivileged accounts to takeover critical hybrid assets.

Replace Enterprise or Domain Admin account for Microsoft Entra Connect AD DS Connector account

Description

Smart attackers often target Microsoft Entra Connect in on-premises environments due to the elevated privileges associated with its AD DS Connector account (typically created in Active Directory with the MSOL_ prefix). Using an Enterprise Admin or Domain Admin account for this purpose significantly increases the attack surface, as these accounts have broad control over the directory.

Starting with Entra Connect build 1.4.###.#, Enterprise Admin and Domain Admin accounts can no longer be used as the AD DS Connector account. This best practice prevents over-privileging the connector account, reducing the risk of domain-wide compromise if the account is targeted by attackers. Organizations must now create or assign a lower-privileged account specifically for directory synchronization, ensuring better adherence to the principle of least privilege and protecting critical admin accounts.

Implementation

  1. Review the recommended action at Microsoft Secure Score actions for Replace Enterprise or Domain Admin account for Microsoft Entra Connect AD DS Connector account.account.

  2. Review the exposed accounts and their group memberships. The list contains members of Domain/Enterprise Admins through direct and recursive membership.

  3. Perform one of the following actions:

    • Remove MSOL_ user account user from privileged groups, ensuring it retains the necessary permissions to function as the Microsoft Entra Connect Connector account.

    • Change the Microsoft Entra Connect AD DS Connector account (MSOL_) to a lower-privileged account.
