| Scope | Rule Name | Description | Reference | Last Update |
|---|---|---|---|---|
| Azure SQL Database | Database users shouldn't share the same name as a server login for Model SQL database | Database users might share the same name as a server login. This rule validates that there are no such users. | Defender for Cloud | June 2026 |
| Azure SQL Database | The Trustworthy bit should be disabled on all databases except MSDB for SQL Databases | The TRUSTWORTHY database property is used to indicate whether the instance of SQL Server trusts the database and the contents within it. If this option is enabled database modules (for example user-defined functions or stored procedures) that use an impersonation context can access resources outside the database. This rule verifies that the TRUSTWORTHY bit is disabled on all databases except MSDB. | Defender for Cloud | June 2026 |
| Azure SQL Database | Orphan database roles should be removed from SQL databases | Orphan roles are user-defined roles that have no members. Eliminate orphaned roles as they are not needed on the system. This rule checks whether there are any orphan roles. | Defender for Cloud | June 2026 |
| Azure SQL Database | Database-level firewall rules should not grant excessive access for SQL Servers | The Azure SQL Database-level firewall helps protect your data by preventing all access to your database until you specify which IP addresses have permission. Database-level firewall rules grant access to the specific database based on the originating IP address of each request. Database-level firewall rules for master and user databases can only be created and managed through Transact-SQL (unlike server-level firewall rules, which can also be created and managed using the Azure portal or PowerShell). For more information, see Azure SQL Database and Azure Synapse Analytics IP firewall rules. This check verifies that database-level firewall rules do not grant access to more than 255 IP addresses. | Defender for Cloud | June 2026 |
| Azure SQL Database | Database-level firewall rules should be tracked and maintained at a strict minimum for SQL Servers | The Azure SQL Database-level firewall helps protect your data by preventing all access to your database until you specify which IP addresses have permission. Database-level firewall rules grant access to the specific database based on the originating IP address of each request. Database-level firewall rules for master and user databases can only be created and managed through Transact-SQL (unlike server-level firewall rules, which can also be created and managed using the Azure portal or PowerShell). For more information, see Azure SQL Database and Azure Synapse Analytics IP firewall rules. This check enumerates all the database-level firewall rules so that any changes made to them can be identified and addressed. | Defender for Cloud | June 2026 |
| Azure SQL Database | Minimal set of principals should be members of fixed Azure SQL Database master database roles | SQL Database provides two restricted administrative roles in the master database to which user accounts can be added that grant permissions to either create databases or manage logins. This rule check that a minimal set of principals are members of these administrative roles. | Defender for Cloud | June 2026 |
| Azure SQL Database | Track all users with access to the database for SQL Databases | This check tracks all users with access to a database. Make sure that these users are authorized according to their current role in the organization. | Defender for Cloud | June 2026 |
| Azure SQL Database;SQL virtual machine | Principal GUEST should not be granted permissions in SQL databases | Each database includes a user called GUEST. Permissions granted to GUEST are inherited by users who have access to the database but who do not have a user account in the database. This rule checks that all permissions have been revoked from the GUEST user. | Defender for Cloud | June 2026 |
| Azure SQL Database;SQL virtual machine | Principal GUEST should not be granted permissions on objects or columns in SQL databases | Each database includes a user called GUEST. Permissions granted to GUEST are inherited by users who have access to the database but who do not have a user account in the database. This rule checks that all permissions have been revoked from the GUEST user | Defender for Cloud | June 2026 |
| Azure SQL Database;SQL virtual machine | Transparent data encryption should be enabled for SQL databases | Transparent data encryption (TDE) helps to protect the database files against information disclosure by performing real-time encryption and decryption of the database, associated backups, and transaction log files 'at rest', without requiring changes to the application. This rule checks that TDE is enabled on the database. | Defender for Cloud | June 2026 |
| Azure SQL Database;SQL virtual machine | User-defined database roles should not be members of fixed roles in SQL databases | To easily manage the permissions in your databases SQL Server provides several roles, which are security principals that group other principals. They are like groups in the Microsoft Windows operating system. Database accounts and other SQL Server roles can be added into database-level roles. Each member of a fixed-database role can add other users to that same role. This rule checks that no user-defined roles are members of fixed roles. | Defender for Cloud | June 2026 |
| Azure SQL Database;SQL virtual machine | Database owners should be as expected for SQL databases | Database owners can perform all configuration and maintenance activities on the database and can also drop databases in SQL Server. Tracking database owners is important to avoid having excessive permission for some principals. Create a baseline that defines the expected database owners for the database. This rule checks whether the database owners are as defined in the baseline. | Defender for Cloud | June 2026 |
| Azure SQL Database;SQL virtual machine | All memberships for user-defined roles should be intended in SQL databases | User-defined roles are security principals defined by the user to group principals to easily manage permissions. Monitoring these roles is important to avoid having excessive permissions. Create a baseline that defines expected membership for each user-defined role. This rule checks whether all memberships for user-defined roles are as defined in the baseline. | Defender for Cloud | June 2026 |
| Azure SQL Database;SQL virtual machine | Minimal set of principals should be granted ALTER or ALTER ANY USER database-scoped permissions in SQL databases | Every SQL Server securable has permissions associated with it that can be granted to principals. Permissions can be scoped at the server level (assigned to logins and server roles) or at the database level (assigned to database users and database roles). These rules check that only a minimal set of principals are granted ALTER or ALTER ANY USER database-scoped permissions. | Defender for Cloud | June 2026 |
| Azure SQL Database;SQL virtual machine | Minimal set of principals should be granted EXECUTE permission on objects or columns in SQL databases | This rule checks which principals are granted EXECUTE permission on objects or columns to ensure this permission is granted to a minimal set of principals. Every SQL Server securable has permissions associated with it that can be granted to principals. Permissions can be scoped at the server level (assigned to logins and server roles) or at the database level (assigned to database users, database roles, or application roles). The EXECUTE permission applies to both stored procedures and scalar functions, which can be used in computed columns. | Defender for Cloud | June 2026 |
| Azure SQL Database;SQL virtual machine | Minimal set of principals should be members of fixed high impact database roles in SQL databases | SQL Server provides roles to help manage the permissions. Roles are security principals that group other principals. Database-level roles are database-wide in their permission scope. This rule checks that a minimal set of principals are members of the fixed database roles. | Defender for Cloud | June 2026 |
| Azure SQL Database;SQL virtual machine | Minimal set of principals should be members of fixed low impact database roles in SQL databases | SQL Server provides roles to help manage the permissions. Roles are security principals that group other principals. Database-level roles are database-wide in their permission scope. This rule checks that a minimal set of principals are members of the fixed database roles. | Defender for Cloud | June 2026 |
| Azure SQL Database;SQL virtual machine | Changes to signed modules should be authorized for SQL databases | You can sign a stored procedure, function, or trigger with a certificate or an asymmetric key. This is designed for scenarios when permissions cannot be inherited through ownership chaining or when the ownership chain is broken, such as dynamic SQL. This rule checks for changes made to signed modules, which could be an indication of malicious use. | Defender for Cloud | June 2026 |
| Azure SQL Server | Maximum number of error logs should be 12 or more for SQL Servers | Each SQL Server Error log will have all the information related to failures / errors that have occurred since SQL Server was last restarted or since the last time you have recycled the error logs. This rule checks that the maximum number of error logs is 12 or more. | Defender for Cloud | June 2026 |
| Azure SQL Server | Server-level firewall rules should be tracked and maintained at a strict minimum on SQL Servers | The Azure SQL server-level firewall helps protect your data by preventing all access to your databases until you specify which IP addresses have permission. Server-level firewall rules grant access to all databases that belong to the server based on the originating IP address of each request. Server-level firewall rules can be created and managed through Transact-SQL as well as through the Azure portal or PowerShell. For more information, see Azure SQL Database and Azure Synapse Analytics IP firewall rules. This check enumerates all the server-level firewall rules so that any changes made to them can be identified and addressed. | Defender for Cloud | June 2026 |
| Container App | Authentication should be enabled on Azure Container Apps | This recommendation checks whether authentication is enabled for Azure Container Apps. When authentication is not configured, publicly accessible container app endpoints may allow anonymous HTTP requests. Enabling authentication ensures that requests are validated using identity providers before reaching the container app, reducing the risk of unauthorized access and misuse. | Defender for Cloud | June 2026 |
| Container App | Azure Container Apps should not be exposed to the public internet unless required | This recommendation checks whether Azure Container Apps are exposed to the public internet. Public exposure increases the attack surface and may allow unauthorized access if additional controls are not in place. Unless business requirements explicitly demand public ingress, container apps should be deployed in internal environments or configured with private network access to reduce internet‑based threats. | Defender for Cloud | June 2026 |
| Container App | Managed identities assigned to Azure Container Apps should follow least privilege | This recommendation checks whether managed identities assigned to Azure Container Apps are granted only the minimum permissions required to perform their intended functions. Over‑privileged managed identities can increase the impact of a compromised application by allowing broader access to Azure resources. Following the principle of least privilege reduces the risk of unauthorized actions and limits potential blast radius. | Defender for Cloud | June 2026 |
| Container Instance | Azure Container Instances should not be publicly exposed | This recommendation checks whether Azure Container Instances are publicly exposed by using a public IP address. Publicly exposed container instances can be accessed directly from the internet, increasing the risk of unauthorized access and attacks. Container instances should be deployed with private network access unless public exposure is explicitly required. | Defender for Cloud | June 2026 |
| Container Instance | Managed identities assigned to Azure Container Instances should follow least privilege | This recommendation checks whether managed identities assigned to Azure Container Instances are granted only the minimum permissions required for their operation. Over‑privileged managed identities increase the potential impact of a compromised container instance by allowing broader access to Azure resources. Applying the principle of least privilege helps reduce attack surface and limits the blast radius of security incidents. | Defender for Cloud | June 2026 |
| Function App | Authentication should be enabled on Azure Functions | This recommendation checks whether authentication is enabled for Azure Functions. When authentication is not configured, function endpoints may be publicly accessible without identity verification. Enabling authentication ensures that only authorized users or applications can invoke functions, reducing the risk of unauthorized access, data exposure, or abuse. | Defender for Cloud | June 2026 |
| Function App | Restricted network access should be configured on Internet exposed Function app | This recommendation checks whether restricted network access is configured for Azure Function Apps that are exposed to the internet. When a Function App is publicly accessible without network restrictions, it can be reached by any external client, increasing the risk of unauthorized access and abuse. Configuring restricted network access—such as IP restrictions, virtual network integration, or private endpoints—limits who can reach the Function App and reduces its public attack surface. | Defender for Cloud | June 2026 |
| Kubernetes services | CNI plugins should be configured on Azure Kubernetes Services (AKS) clusters | This recommendation is issued by Microsoft Defender for Cloud as part of Kubernetes security posture management. It is based on AKS official networking requirements, which state that clusters created with --network-plugin none must have a Container Network Interface (CNI) plugin explicitly configured. Failure to deploy a CNI results in non-functional pod and node networking and represents a misconfiguration against Microsoft Cloud Security Benchmark (Network Security controls). | Defender for Cloud | June 2026 |
| Kubernetes services | Private endpoint access should be enabled for the control plane in Azure Kubernetes Service (AKS) clusters | This recommendation promotes enabling Private Endpoint for the AKS control plane, based on AKS private cluster architecture and the built‑in Azure Policy “Azure Kubernetes Service Private Clusters should be enabled”. | Defender for Cloud | June 2026 |
| Kubernetes services | Private nodes should be configured on Azure Kubernetes Service (AKS) clusters | This recommendation checks whether AKS cluster nodes are configured as private nodes without public IP addresses. When nodes are assigned public IPs, they can be directly reachable from the internet, increasing the attack surface of the cluster. Configuring private nodes ensures that cluster nodes are only accessible through internal virtual network connectivity, reducing exposure and supporting a more secure network isolation model. | Defender for Cloud | June 2026 |
| PostgreSQL flexible server;PostgreSQL server | Allow access to Azure services' should be disabled for PostgreSQL Servers | This recommendation checks whether the “Allow access to Azure services” firewall setting is enabled on Azure Database for PostgreSQL servers. When this option is enabled, the PostgreSQL server can be accessed by any Azure service without explicit network rules. Disabling this setting enforces stricter network access control and ensures that only explicitly allowed networks or private endpoints can connect to the database. | Defender for Cloud | June 2026 |
| PostgreSQL flexible server;PostgreSQL server | Private endpoint should be configured for Azure Database for PostgreSQL Servers | This recommendation checks whether Azure Database for PostgreSQL servers are configured to use a private endpoint. When a private endpoint is not enabled, database access may rely on public network exposure or broad firewall rules. Configuring a private endpoint ensures that database connectivity is restricted to a virtual network, reducing exposure to the public internet and improving overall network isolation for sensitive data workloads. | Defender for Cloud | June 2026 |
| PostgreSQL flexible server;PostgreSQL server | Public IP access should be disabled for Azure Database for PostgreSQL Servers | This recommendation checks whether public IP access is enabled for Azure Database for PostgreSQL servers. Allowing public IP access exposes the database to potential internet-based threats, even when firewall rules are configured. Disabling public IP access reduces the attack surface and ensures that database connectivity relies on private network access, such as private endpoints and virtual networks. | Defender for Cloud | June 2026 |
| PostgreSQL flexible server;PostgreSQL server | require_secure_transport should be set to 'on' for Azure Database for PostgreSQL Servers | This recommendation checks whether the PostgreSQL server parameter require_secure_transport is set to on.

Enabling require_secure_transport enforces TLS encryption for all connections, helping protect sensitive data and credentials from interception during network transmission. | Defender for Cloud | June 2026 |
| PostgreSQL flexible server;PostgreSQL server | shared_preload_libraries should include pgaudit for Azure Database for PostgreSQL Servers | This recommendation checks whether the PostgreSQL server configuration parameter shared_preload_libraries includes pgaudit. The pgAudit extension provides detailed logging of database activities such as SQL statements, schema changes, and access patterns. If pgaudit is not preloaded at server startup, database activity auditing is not available. Enabling pgAudit strengthens monitoring, compliance, and forensic investigation capabilities. | Defender for Cloud | June 2026 |
| PostgreSQL flexible server;PostgreSQL server | pgaudit.log should include role, ddl, and misc for Azure Database for PostgreSQL Servers | This recommendation checks whether the PostgreSQL pgAudit configuration includes auditing for role changes, DDL operations, and miscellaneous administrative actions by ensuring that pgaudit.log includes role, ddl, and misc. Without these settings, critical security‑relevant database activities may not be logged, reducing visibility into privileged actions and weakening auditing and compliance capabilities. | Defender for Cloud | June 2026 |
| PostgreSQL flexible server;PostgreSQL server | pgaudit.log_level should be set to 'log' for Azure Database for PostgreSQL Servers | This recommendation checks whether the PostgreSQL pgAudit configuration parameter pgaudit.log_level is set to log. If the log level is set to a less restrictive value, audit events may not be consistently captured or forwarded to centralized logging systems. Setting pgaudit.log_level to log ensures that audit records are reliably written to PostgreSQL logs and available for security monitoring, compliance, and forensic analysis. | Defender for Cloud | June 2026 |
| PostgreSQL flexible server;PostgreSQL server | pgaudit.log_statement should be set to 'on' for Azure Database for PostgreSQL Servers | This recommendation checks whether the PostgreSQL pgAudit parameter pgaudit.log_statement is set to on. When this setting is disabled, audit logs may omit the actual SQL statements associated with audited events. Enabling pgaudit.log_statement ensures that audited database activities include statement details, strengthening monitoring, investigation, and compliance capabilities. | Defender for Cloud | June 2026 |
| PostgreSQL flexible server;PostgreSQL server | pgaudit.log_statement_once should be set to 'on' for Azure Database for PostgreSQL Servers | This recommendation checks whether the PostgreSQL pgAudit parameter pgaudit.log_statement_once is set to on. When this setting is disabled, the same SQL statement may be logged multiple times for a single audited event, leading to excessive and noisy audit logs. Enabling pgaudit.log_statement_once ensures that each audited SQL statement is logged only once, improving audit log clarity while maintaining full audit coverage. | Defender for Cloud | June 2026 |
| PostgreSQL flexible server;PostgreSQL server | password_encryption should be set to 'scram-sha-256' for Azure Database for PostgreSQL servers | This recommendation checks whether the PostgreSQL server parameter password_encryption is set to scram-sha-256. When weaker encryption methods such as MD5 are used, stored credentials may be more susceptible to brute-force or compromise. Configuring password_encryption to scram-sha-256 ensures stronger password hashing and improves protection of database user credentials. | Defender for Cloud | June 2026 |
| PostgreSQL flexible server;PostgreSQL server | log_checkpoints should be set to on for Azure Database for PostgreSQL Servers | This recommendation checks whether the PostgreSQL server parameter log_checkpoints is enabled. When checkpoint logging is disabled, critical information about checkpoint activity is not recorded, reducing visibility into database behavior and performance. Enabling log_checkpoints helps administrators monitor checkpoint activity, detect abnormal patterns, and support troubleshooting and forensic analysis. | Defender for Cloud | June 2026 |
| PostgreSQL flexible server;PostgreSQL server | log_connections should be set to 'on' for PostgreSQL Servers | This recommendation checks whether the PostgreSQL server parameter log_connections is enabled. When connection logging is disabled, successful database connection attempts are not recorded, reducing visibility into access patterns and potentially hiding unauthorized or suspicious activity. Enabling log_connections helps administrators monitor database access, detect anomalies, and support security investigations. | Defender for Cloud | June 2026 |
| PostgreSQL flexible server;PostgreSQL server | log_disconnections should be set to 'on' for PostgreSQL Servers | This recommendation checks whether the PostgreSQL server parameter log_disconnections is enabled. When disconnection logging is disabled, information about when and how database sessions end is not recorded. Enabling log_disconnections improves visibility into session behavior, supports security investigations, and helps diagnose abnormal or unexpected disconnections. | Defender for Cloud | June 2026 |
| PostgreSQL flexible server;PostgreSQL server | log_line_prefix should include key identifiers for auditing and troubleshooting for Azure Database for PostgreSQL Servers | This recommendation checks whether the PostgreSQL server parameter log_line_prefix is configured to include key identifiers such as user, database name, process ID, or session information. When log entries lack sufficient contextual identifiers, auditing, troubleshooting, and security investigations become difficult. Including key identifiers in the log line prefix improves traceability and helps correlate log events with specific users and sessions. | Defender for Cloud | June 2026 |
| PostgreSQL flexible server;PostgreSQL server | logfiles.retention_days should be greater than 3 for PostgreSQL Servers | This recommendation checks whether the PostgreSQL server log retention period, defined by logfiles.retention_days, is configured to retain logs for more than three days. When log retention is too short, important security, audit, and troubleshooting information may be lost before it can be reviewed or investigated. Increasing log retention improves the ability to perform security investigations, compliance audits, and root‑cause analysis. | Defender for Cloud | June 2026 |
| PostgreSQL flexible server;PostgreSQL server | Geo-redundant backups should be enabled for PostgreSQL Servers | This recommendation checks whether geo‑redundant backups are enabled for Azure Database for PostgreSQL servers. Without geo‑redundant backups, backups are stored in a single region, which may result in data unavailability or loss in the event of a regional outage. Enabling geo‑redundant backups improves data resilience and ensures database recovery is possible even during region‑wide failures. | Defender for Cloud | June 2026 |
| PostgreSQL flexible server;PostgreSQL server | Connection_throttle should be set to 'on' for PostgreSQL Servers | This recommendation checks whether the PostgreSQL server parameter connection_throttle is enabled. When connection throttling is disabled, the database may allow an excessive number of rapid connection attempts, increasing the risk of brute‑force attacks, credential abuse, or resource exhaustion. Enabling connection_throttle helps limit abnormal connection behavior and protects the database from abuse and denial‑of‑service scenarios. | Defender for Cloud | June 2026 |
| SQL virtual machine | Latest updates should be installed for SQL Servers | Microsoft periodically releases Cumulative Updates (CUs) for each version of SQL Server. This rule checks whether the latest CU has been installed for the particular version of SQL Server being used, by passing in a string for execution. This rule checks that all users (except dbo) do not have permission to execute the xp_cmdshell extended stored procedure. | Defender for Cloud | June 2026 |
| SQL virtual machine | Untracked trusted assemblies should be removed for SQL Servers | Assemblies marked as UNSAFE are required to be signed by a certificate or asymmetric key with a corresponding login that has been granted UNSAFE ASSEMBLY permission in the master database. Trusted assemblies might bypass this requirement. | Defender for Cloud | June 2026 |
| SQL virtual machine | Remote Admin Connections should be disabled unless specifically required for SQL databases | This rule checks that remote dedicated admin connections are disabled if they are not being used for clustering to reduce attack surface area. SQL Server provides a dedicated administrator connection (DAC). The DAC lets an administrator access a running server to execute diagnostic functions or Transact-SQL statements, or to troubleshoot problems on the server and it becomes an attractive target to attack when it is enabled remotely. | Defender for Cloud | June 2026 |
| SQL virtual machine | Password expiration check should be enabled for all SQL logins on SQL Servers | Password expiration policies are used to manage the lifespan of a password. When SQL Server enforces password expiration policy, users are reminded to change old passwords, and accounts that have expired passwords are disabled. This rule checks that password expiration policy is enabled for all SQL logins. | Defender for Cloud | June 2026 |

| SQL virtual machine | Unused service broker endpoints should be removed for SQL Servers | Service Broker provides queuing and reliable messaging for SQL Server. Service Broker is used both for applications that use a single SQL Server instance and applications that distribute work across multiple instances. Service Broker endpoints provide options for transport security and message forwarding. This rule enumerates all the service broker endpoints. Remove those that are not used. | Defender for Cloud | June 2026 |
| SQL virtual machine | Server permissions shouldn't be granted directly to principals for SQL Servers | Server level permissions are associated with a server level object to regulate which users can gain access to the object. This rule checks that there are no server level permissions granted directly to logins. | Defender for Cloud | June 2026 |
| SQL virtual machine | Scan for startup stored procedures' option should be disabled for SQL Servers | When 'Scan for startup procs' is enabled SQL Server scans for and runs all automatically run stored procedures defined on the server. If this option is enabled SQL Server scans for and runs all automatically run stored procedures defined on the server. This rule checks that this option is disabled. | Defender for Cloud | June 2026 |
| SQL virtual machine | Authentication mode should be Windows Authentication for SQL Servers | There are two possible authentication modes: Windows Authentication mode and mixed mode. Mixed mode means that SQL Server enables both Windows authentication and SQL Server authentication. This rule checks that the authentication mode is set to Windows Authentication. | Defender for Cloud | June 2026 |
| SQL virtual machine | Auditing of both successful and failed login attempts (default trace) should be enabled when 'Login auditing' is set up to track logins for SQL Servers | SQL Server Login auditing configuration enables administrators to track the users logging into SQL Server instances. If the user chooses to count on 'Login auditing' to track users logging into SQL Server instances, then it is important to enable it for both successful and failed login attempts. | Defender for Cloud | June 2026 |
| SQL virtual machine | AES encryption should be required for any Existing Mirroring or SSB endpoint on SQL Databases | Service Broker and Mirroring endpoints support different encryption algorithms including no-encryption. This rule checks that any existing endpoint requires AES encryption. | Defender for Cloud | June 2026 |
| SQL virtual machine | Model database should only be accessible by Only 'dbo' should have access to Model SQL database | The Model database is used as the template for all databases created on the instance of SQL Server. Modifications made to the model database such as database size recovery model and other database options are applied to any databases created afterward. This rule checks that dbo is the only account allowed to access the model database. | Defender for Cloud | June 2026 |
| SQL virtual machine | Server configuration 'Replication XPs' should be disabled for SQL Servers | Disable the deprecated server configuration 'Replication XPs' to limit the attack surface area. This is an internal only configuration setting. | Defender for Cloud | June 2026 |
| SQL virtual machine | Orphaned users should be removed from SQL server databases | A database user that exists on a database but has no corresponding login in the master database or as an external resource (for example, a Windows user) is referred to as an orphaned user and it should either be removed or remapped to a valid login. This rule checks that there are no orphaned users. | Defender for Cloud | June 2026 |
| SQL virtual machine | The database owner information in the database should match the respective database owner information in the master database for SQL databases | There is redundant information about the dbo identity for any database: metadata stored in the database itself and metadata stored in master DB. This rule checks that this information is consistent between the target DB and master. | Defender for Cloud | June 2026 |
| SQL virtual machine | There should be no SPs marked as auto-start for SQL Servers | When SQL Server has been configured to 'scan for startup procs' the server will scan master DB for stored procedures marked as auto-start. This rule checks that there are no SPs marked as auto-start. | Defender for Cloud | June 2026 |
| SQL virtual machine | User CLR assemblies should not be defined in SQL databases | CLR assemblies can be used to execute arbitrary code on SQL Server process. This rule checks that there are no user-defined CLR assemblies in the database. | Defender for Cloud | June 2026 |
