.NAME
SqlAudit .SYNOPSIS The SqlAudit DSC resource is used to create, modify, or remove server audits. .DESCRIPTION The SqlAudit DSC resource is used to create, modify, or remove server audits. The built-in parameter PSDscRunAsCredential can be used to run the resource as another user. The resource will then authenticate to the SQL Server instance as that user. It also possible to instead use impersonation by the parameter Credential. ## Requirements * Target machine must be running Windows Server 2012 or later. * Target machine must be running SQL Server Database Engine 2012 or later. * Target machine must have access to the SQLPS PowerShell module or the SqlServer PowerShell module. ## Known issues All issues are not listed here, see https://github.com/dsccommunity/SqlServerDsc/issues?q=is%3Aissue+is%3Aopen+in%3Atitle+SqlAudit. ### Property Reasons does not work with PSDscRunAsCredential When using the built-in parameter PSDscRunAsCredential the read-only property Reasons will return empty values for the properties Code and **Phrase. The built-in property PSDscRunAsCredential does not work together with class-based resources that using advanced type like the parameter Reasons have. ### Using Credential property SQL Authentication and Group Managed Service Accounts is not supported as impersonation credentials. Currently only Windows Integrated Security is supported to use as credentials. For Windows Authentication the username must either be provided with the User Principal Name (UPN), e.g. username@domain.local or if using non-domain (for example a local Windows Server account) account the username must be provided without the NetBIOS name, e.g. username. Using the NetBIOS name, e.g using the format DOMAIN\username will not work. See more information in https://github.com/dsccommunity/SqlServerDsc/wiki/CredentialOverview. .PARAMETER Name Key - System.String The name of the audit. .PARAMETER LogType Write - System.String Allowed values: SecurityLog, ApplicationLog Specifies the to which log an audit logs to. Mutually exclusive to parameter Path. .PARAMETER Path Write - System.String Specifies the destination path for a file audit. Mutually exclusive to parameter LogType. .PARAMETER AuditFilter Write - System.String .PARAMETER MaximumFiles Write - Nullable[System.UInt32] Specifies the number of files on disk. Mutually exclusive to parameter MaximumRolloverFiles. Mutually exclusive to parameter LogType. .PARAMETER MaximumFileSize Write - Nullable[System.UInt32] Specifies the maximum file size in units by parameter MaximumFileSizeUnit. If this is specified the parameter MaximumFileSizeUnit must also be specified. Mutually exclusive to parameter LogType. Minimum allowed value is 2 (MB). It also allowed to set the value to 0 which mean unlimited file size. .PARAMETER MaximumFileSizeUnit Write - System.String Allowed values: Megabyte, Gigabyte, Terabyte Specifies the unit that is used for the file size. If this is specified the parameter MaximumFileSize must also be specified. Mutually exclusive to parameter LogType. .PARAMETER MaximumRolloverFiles Write - Nullable[System.UInt32] Specifies the amount of files on disk before SQL Server starts reusing the files. Mutually exclusive to parameter MaximumFiles and LogType. .PARAMETER OnFailure Write - System.String Allowed values: Continue, FailOperation, Shutdown Specifies what should happen when writing events to the store fails. This can be Continue, FailOperation, or Shutdown. .PARAMETER QueueDelay Write - Nullable[System.UInt32] Specifies the maximum delay before a event is written to the store. When set to low this could impact server performance. When set to high events could be missing when a server crashes. .PARAMETER AuditGuid Write - System.String .PARAMETER ReserveDiskSpace Write - Nullable[System.Boolean] Specifies if the needed file space should be reserved. only needed when writing to a file log. Mutually exclusive to parameter LogType. .PARAMETER Enabled Write - Nullable[System.Boolean] Specifies if the audit should be enabled. Defaults to $false. .PARAMETER Ensure Write - Ensure Specifies if the server audit should be present or absent. If set to Present the audit will be added if it does not exist, or updated if the audit exist. If Absent then the audit will be removed from the server. Defaults to Present. .PARAMETER Force Write - Nullable[System.Boolean] Specifies if it is allowed to re-create the server audit if a current audit exist with the same name but of a different audit type. Defaults to $false not allowing server audits to be re-created. .EXAMPLE 1 This example shows how to ensure that an audit destination is absent on the instance sqltest.company.local\DSC. Configuration Example { param ( [Parameter(Mandatory = $true)] [System.Management.Automation.PSCredential] $SqlAdministratorCredential ) Import-DscResource -ModuleName SqlServerDsc node localhost { SqlAudit FileAudit_Server { Ensure = 'Present' ServerName = 'SQL2019-01' InstanceName = 'INST01' Name = 'FileAudit' Path = 'C:\Temp\audit' MaximumFileSize = 10 MaximumFileSizeUnit = 'Megabyte' MaximumRolloverFiles = 11 Enabled = $true Credential = $SqlAdministratorCredential } } } .EXAMPLE 2 This example shows how to ensure that the windows security event log audit destination is present on the instance sqltest.company.local\DSC. Configuration Example { param ( [Parameter(Mandatory = $true)] [System.Management.Automation.PSCredential] $SqlAdministratorCredential ) Import-DscResource -ModuleName SqlServerDsc node localhost { SqlAudit SecurityLogAudit_Server { Ensure = 'Present' ServerName = 'sqltest.company.local' InstanceName = 'DSC' Name = 'SecLogAudit' LogType = 'SecurityLog' Enabled = $true Credential = $SqlAdministratorCredential } } } .EXAMPLE 3 This example shows how to ensure that the windows security event log audit destination is present on the instance sqltest.company.local\DSC. The server should shutdown when logging is not possible. Configuration Example { param ( [Parameter(Mandatory = $true)] [System.Management.Automation.PSCredential] $SqlAdministratorCredential ) Import-DscResource -ModuleName SqlServerDsc node localhost { SqlAudit SecurityLogAudit_Server { Ensure = 'Present' ServerName = 'sqltest.company.local' InstanceName = 'DSC' Name = 'SecLogAudit' OnFailure = 'Shutdown' Enabled = $true Credential = $SqlAdministratorCredential } } } .EXAMPLE 4 This example shows how to ensure that the windows security event log audit destination is present on the instance sqltest.company.local\DSC. and adds a filter so only users with a name lie administrator are audited Configuration Example { param ( [Parameter(Mandatory = $true)] [System.Management.Automation.PSCredential] $SqlAdministratorCredential ) Import-DscResource -ModuleName SqlServerDsc node localhost { SqlAudit SecurityLogAudit_Server { Ensure = 'Present' ServerName = 'sqltest.company.local' InstanceName = 'DSC' Name = 'SecLogAudit' LogType = 'SecurityLog' Enabled = $true AuditFilter = '([server_principal_name] like ''%ADMINISTRATOR'')' Credential = $SqlAdministratorCredential } } } .EXAMPLE 5 This example shows how to ensure that an audit destination is absent on the instance sqltest.company.local\DSC. Configuration Example { param ( [Parameter(Mandatory = $true)] [System.Management.Automation.PSCredential] $SqlAdministratorCredential ) Import-DscResource -ModuleName SqlServerDsc node localhost { SqlAudit FileAudit_Server { Ensure = 'Absent' ServerName = 'sqltest.company.local' InstanceName = 'DSC' Name = 'FileAudit' Credential = $SqlAdministratorCredential } } } |
