Get Previous and Scheduled Evaluation Times for ConfigMgr Compliance Baselines with PowerShell

January 20, 2020 by Trevor Jones, posted in Compliance, ConfigMgr, Powershell, Reporting, SCCM

I was testing a compliance baseline recently and wanted to verify if the schedule defined in the baseline deployment is actually honored on the client. I set the schedule to run every hour, but it was clear that it did not run every hour and that some randomization was being used.

To review the most recent evaluation times and the next scheduled evaluation time, I had to read the scheduler.log in the CCM\Logs directory, because I could only find a single last evaluation time recorded in WMI.

The following PowerShell script reads which baselines are currently deployed to the local machine, displays a window for you to choose one, then basically reads the Scheduler log to find when the most recent evaluations were and when the next one is scheduled.

Inventory Local Administrator Privileges with PowerShell and ConfigMgr

May 25, 2017 by Trevor Jones, posted in Compliance, ConfigMgr, Powershell, Reporting, SCCM, SQL

Any security-conscious enterprise will want to have visibility of which users have local administrator privilege on any given system, and if you are an SCCM administrator then the job of gathering this information will likely be handed to you!

However, this task may not be as simple as it seems. Gathering the membership of the local administrators group is one thing, but perhaps more important to know is whether the primary user of a system has administrator privileges. If that user is a member of a group that has been added to the local administrators group, then it isn’t immediately obvious whether they actually have administrator rights without also checking the membership of that group. And what if there are further nested groups – ie the user is a member of a group that’s a member of a group that’s a member of the local administrators group?! Obviously things can get complicated here, making reporting and compliance checking a challenge.

Thankfully, PowerShell can handle complication quite nicely, and ConfigMgr is more than capable as a both a delivery vehicle and a reporting mechanism, so the good news is – we can do this!

The following solution uses PowerShell to gather local administrator information and stamp it to the local registry. A Compliance item in SCCM is used as the delivery vehicle for the script and then RegKeyToMof is used to update the hardware inventory classes in SCCM to gather this information from the client’s registry into the SCCM database, where we can query and report on it.

Gathering Local Administrator Information with PowerShell

To start with, let’s have a look at some of the PowerShell code and the information we will gather with it.

First, we need to identify who is the primary user of the system. Since the script is running locally on the client computer, we will not use User Device Affinity. True, UDA information is stored in WMI in the CCM_UserAffinity class, in the ROOT\CCM\Policy\Machine\ActualConfig namespace. But this class can contain multiple instances so you can’t always determine the primary user that way.

A better way is to use the SMS_SystemConsoleUsage class in the ROOT\cimv2\sms namespace and query the TopConsoleUser property. This will give you the user account who has had the most interactive logons on the system and for the most part will indicate who the primary user is.


$TopConsoleUser = Get-WmiObject -Namespace ROOT\cimv2\sms -Class SMS_SystemConsoleUsage -Property TopConsoleUser -ErrorAction Stop | Select -ExpandProperty TopConsoleUser

Next, to find if the user is a local admin or not, we will not simply query the local administrator group membership and check if the user is in there. Instead we will create a WindowsIdentity object in .Net and run a method called HasClaim(). I describe this more in a previous blog, but using this method we can determine if the user has local administrator privilege whether through direct membership or through a nested group.


$ID = New-Object Security.Principal.WindowsIdentity -ArgumentList $TopConsoleUser
$IsLocalAdmin = $ID.HasClaim('http://schemas.microsoft.com/ws/2008/06/identity/claims/groupsid','S-1-5-32-544')
$ID.Dispose()

The SID for the local admin group (S-1-5-32-544) is used as this is the same across all systems. This will only work for domain accounts as it uses kerberos to create the identity.

Now we will also get the local administrator group membership using the following code (more .Net stuff), and filter just the SamAccountNames.


Add-Type -AssemblyName System.DirectoryServices.AccountManagement -ErrorAction Stop
$ContextType = [System.DirectoryServices.AccountManagement.ContextType]::Machine
$PrincipalContext = New-Object -TypeName System.DirectoryServices.AccountManagement.PrincipalContext -ArgumentList $ContextType, $($env:COMPUTERNAME) -ErrorAction Stop
$IdentityType = [System.DirectoryServices.AccountManagement.IdentityType]::Name
$GroupPrincipal = [System.DirectoryServices.AccountManagement.GroupPrincipal]::FindByIdentity($PrincipalContext, $IdentityType, “Administrators”)
$LocalAdminMembers = $GroupPrincipal.Members | select -ExpandProperty SamAccountName | Sort-Object
$PrincipalContext.Dispose()
$GroupPrincipal.Dispose()

Next, if the user is a local admin through nested group membership, I will call a custom function which will check the nested group membership within the local admin group, for the user account. Let’s say that Group B is a member of Group A, which is a member of the local administrators group. We will check the membership of both Groups B and A to see which ones the user is a member of, and therefore which group/s is effectively giving the user administrator privilege. We do this by querying the $GroupPrincipal object created in the previous code. The custom function will query nested membership up to 3 levels deep.

Now I will query the Install Date for the operating system, since in some cases where a machine is newly built, the TopConsoleUser may not yet be the primary user of the system, but the admin who built the machine, for example. This date helps to identify any such systems.


[datetime]$InstallDate = [System.Management.ManagementDateTimeConverter]::ToDateTime($(Get-WmiObject win32_OperatingSystem -Property InstallDate -ErrorAction Stop | Select -ExpandProperty InstallDate)) | Get-date -Format 'yyyy-MM-dd HH:mm:ss'

Now we gather all this information into a datatable, and call another custom function to write it to the local registry. I use the following registry key, but you can change this in the script if you wish:

HKLM:SOFTWARE\IT_Local\LocalAdminInfo

The script will create the key if it doesn’t exist.

Here’s an example of the kind of data that will be gathered:

You can see in this example, that my user account is a local administrator both by direct membership and through nested groups. The actual groups that grant this right are listed in the NestedGroupMembership property.

Create a Compliance Item

Now lets go ahead and create a compliance item in SCCM to run this script.

In the Console, navigate Assets and Compliance > Compliance Settings > Configuration Items.

Click Create Configuration Item

Click Next and select which OS’s you will target. Remember the Windows XP and Server 2003 may not have PowerShell installed.

Click Next again, then click New to create a new setting.

Choose Script as the setting type, and String as the data type.

Now we need to add the scripts. You can download both the discovery and remediation scripts from my Github repo here:

https://github.com/SMSAgentSoftware/ConfigMgr/tree/master/PowerShell%20Scripts/Compliance%20Settings/LocalAdministratorInfo

Click Add Script and paste or open the relevant script for each. Make sure Windows Powershell is selected as the script language.

The discovery script simply checks whether the script has been run in the last 15 minutes, and if not returns non-compliant. This allows the script to run according to the schedule you define for it, ie once a day or once a week etc, to keep the information up-to-date in the registry.

The remediation script does the hard work 🙂

Click OK to close the Create Setting window.

Click Next, then click New to create a new Compliance Rule as follows:

Click OK to close, then Next, Next and Close to finish.

Create a Configuration Baseline

Click on Configuration Baselines and Create Configuration Baseline to create a new baseline.

Give it a name, click Add and add the Configuration Item you just created.

Click OK to close.

Deploy the Baseline

Right-click the baseline and choose Deploy. Make sure to remediate noncompliance and select the collection you wish to target.

Update SCCM Hardware Inventory

Creating the MOF Files

For this part you will need the excellent RegKeyToMOF utility, which you can download from here:

https://gallery.technet.microsoft.com/RegKeyToMof-28e84c28

You will also need to do this on a machine that has either run the remediation script to create the registry keys, or has run the configuration baseline.

Open RegKeyToMOF and browse to the registry key:

HKLM:SOFTWARE\IT_Local\LocalAdminInfo

You can deselect the ‘Enable 64bits …’ option as the registry key is not located in the WOW6432Node.

Click Save MOF to save the required files.

Copy the SMSDEF.mof and the CM12Import.mof to your SCCM site server.

Update Client Settings

In the SCCM console, navigate Administration > Site Configuration > Client Settings. Open your default client settings and go to the Hardware Inventory page.

Click Set Classes…, then Import…

Browse to the CM12Import.mof and click Import.

Close the Client Settings windows.

Update Configuration.mof

Now open your configuration.mof file at <ConfigMgr Installation Directory> \inboxes\clifiles.src\hinv.

In the section at the bottom for adding extensions, which starts like this…

//========================
// Added extensions start
//========================

…paste the contents of the SMSDEF.mof file. Save and close the file.

Reporting

Now that you’ve deployed the configuration item and updated the SCCM hardware inventory, a new view called dbo.v_GS_LocalAdminInfo0 has been added to the SCCM database. Note that initially there will be no data here until your clients have updated their policies, ran the configuration baseline, and ran the hardware inventory cycle.

You can query using the Queries node in the SCCM console…

…or create yourself a custom SCCM report, create an Excel report with a SQL data connection, query the SCCM database with PowerShell – whatever method you need or prefer.

Here is a sample SQL query that will query the view and add some client health data and the chassis type to help distinguish between desktop, laptops, servers etc.

  ComputerName0 as 'ComputerName',
  Case When enc.ChassisTypes0 = 1 then 'Other'
    when enc.ChassisTypes0 = 2 then 'Unknown'

New Free Tool: ConfigMgr Remote Compliance

March 15, 2017 by Trevor Jones, posted in Compliance, ConfigMgr, Powershell, Reporting, SCCM, Windows Troubleshooting

Today I released a new free tool for ConfigMgr administrators and support staff.

ConfigMgr Remote Compliance can be used to view, evaluate and report on System Center Configuration Manager Compliance Baselines on a remote computer. It provides similar functionality to the Configurations tab of the Configuration Manager Control Panel, but for remote computers. It is a useful troubleshooting tool for remotely viewing client compliance, evaluating baselines, viewing the evaluation report or opening DCM log files from the client, without needing to access the client computer directly.

ConfigMgr Remote Compliance can be downloaded from here.

Source code for this application is available on GitHub and code contributions are welcome.

Deploying Custom Microsoft Office Templates with System Center Configuration Manager

March 8, 2017 by Trevor Jones, posted in Compliance, ConfigMgr, Microsoft Office, Powershell, SCCM

Some time ago a wrote a blog describing a way to deploy custom templates for Microsoft Office applications using SCCM Compliance Settings. Since then, I have re-written the solution into something much more manageable as the previous incarnation was not very clearly defined in how to update templates, and involved some considerable admin overhead. This updated solution is much improved and better manages the lifecycle of your custom templates, including updating, adding and retiring templates. Much of this process is now automated using PowerShell, and I have removed the need to manually specify all the template file names in the scripts so it is also much easier to set up and deploy.

It is relatively detailed, so instead of writing a blog I put this into a free PDF guide which you can download from here:

Export / Backup Compliance Setting Scripts with PowerShell

February 21, 2017 by Trevor Jones, posted in Compliance, ConfigMgr, Powershell, SCCM, SQL

In my SCCM environment I have a number of Compliance Settings that use custom scripts for discovery and remediation, and recently it dawned on me that a lot of time has been spent on these and it would be good to create a backup of those scripts. It would also be useful to be able to export the scripts so they could be edited and tested before being updated in the Configuration Item itself. So I put to together this PowerShell script which does just that!

The Configuration Item scripts are stored in an XML definition, and this can be read from the SCCM database directly and parsed with PowerShell, so that’s what this script does. It will load all the Configuration Items into a datatable from a SQL query, then go through each one looking for any settings that have scripts defined. These scripts will be exported in their native file format.

You could then edit those scripts, or add the export location to your file/folder backup for an extra level of protection for your hard work!

Here you can see an example of the output for my “Java Settings” Configuration item. A subdirectory is created for the current package version, then subdirectories under that for each Configuration setting, then the discovery and remediation scripts for that setting.

cis — Exported Configuration Item Scripts

Note that the script will only process Compliance Items with a CIType_ID of 3, which equates to the Operating System type you will see in the SCCM console for the Configuration Item, which is the type that may use a script as the discovery source.

Removing Disabled Computer Accounts from SCCM with PowerShell

September 1, 2016December 4, 2017 by Trevor Jones, posted in Active Directory, Compliance, ConfigMgr, configmgr client health, Powershell, Reporting, SCCM

In System Center Configuration Manager there are 2 Site Maintenance tasks that help take care of stale or obsolete client records: Delete Aged Discovery Data and Delete Inactive Client Discovery Data. However in some cases some records can remain in SCCM and are not removed by these tasks, for example, when a system is no longer active but the computer account has not been deleted or disabled in Active Directory. AD System Discovery will continue to pick this system up and create a record for it, so maintenance of AD computer accounts is essential for a healthy ConfigMgr environment.

As long as a client is disabled or deleted from Active Directory and does not get picked up by any of the discovery methods, it will eventually get deleted from SCCM according to the schedule defined in these maintenance tasks.

For computer accounts that are disabled however, you might not want to wait for the maintenance tasks to remove them since you know they are no longer active and can safely be deleted from the SCCM database. Removing them sooner can improve compliance figures for deployment reporting, for example. For this scenario, I prepared a PowerShell script that can run as a scheduled task and remove any system that is marked as inactive – or does not have the SCCM client installed – and is also disabled or not present in active directory.

I’ll run through the script quickly here to explain what it does.

First we define some variables to be used in the script, such as the site code, the site server, and the email information (the script will email the SCCM admin with the list of systems it deletes):


$SiteCode = "ABC"
$SiteServer = "SCCMSERVER-01"
$EmailRecipient = "joe.blow@contoso.com"
$EmailSender = "PowerShell@contoso.com"
$SMTPServer = "SMTPServer.contoso.com"

Then we create a list of discovered systems in SCCM that are either inactive (determined by client health data) or have no SCCM client installed, using WMI on the site server:


try
{
    $DevicesToCheck = Get-WmiObject -ComputerName $SiteServer -Namespace root\SMS\Site_$SiteCode -Query "SELECT SMS_R_System.Name FROM SMS_R_System left join SMS_G_System_CH_ClientSummary on SMS_G_System_CH_ClientSummary.ResourceID = SMS_R_System.ResourceID where (SMS_G_System_CH_ClientSummary.ClientActiveStatus = 0 or SMS_R_System.Active = 0 or SMS_R_System.Active is null)" -ErrorAction Stop |
        Select -ExpandProperty Name |
        Sort
}
Catch
{
    $_
}

Next we check active directory for each system to find the status of the computer account and filter those that are either disabled or not present in AD using a custom function. Note that this function uses .Net to search AD so it is not dependent on having the RSAT tools installed.


$NotEnabledDevices = ($DevicesToCheck | foreach {
    Get-IsComputerAccountDisabled  -Computername $_
}) | where {$_.IsDisabled -ne $False}

Then we will attempt to remove each resulting system from SCCM using another custom function. This function uses WMI rather than the ConfigMgr PS cmdlets, again to remove the dependency.


$DeletedRecords = New-Object System.Collections.ArrayList
$Output = $NotEnabledDevices| foreach {
    Remove-CMRecord -Computername $_.ComputerName -DeviceStatus $_.IsDisabled -SiteCode $SiteCode -SiteServer $SiteServer
    }
$DeletedRecords.AddRange(@($Output))

Finally we send an HTML formatted email to the SCCM administrator with the list of systems that were deleted from SCCM:


If ($DeletedRecords.Count -ne 0)
{
    $Body = $DeletedRecords | ConvertTo-Html -Head $style -Body "
<h2>The following computer accounts are either disabled or not present in active directory and have been deleted from SCCM</h2>
" | Out-String
    Send-MailMessage -To $EmailRecipient -From $EmailSender  -Subject "Disabled Computer Accounts Deleted from SCCM ($(Get-Date -format 'yyyy-MMM-dd'))" -SmtpServer $SMTPServer -Body $body -BodyAsHtml
}

To verify in SCCM the systems that were deleted you can view the All Audit Status Messages from a Specific Site status message query.

IMPORTANT: As this script deletes records from the SCCM database, please be sure to understand what it does and to test it first before using it in any production environment!

Here is the full script:


$SiteCode = "ABC"
$SiteServer = "SCCMSERVER-01"
$EmailRecipient = "joe.blow@contoso.com"
$EmailSender = "PowerShell@contoso.com"
$SMTPServer = "SMTPServer.contoso.com"

Disabling Java Content in all Browsers with ConfigMgr Compliance Settings

October 19, 2015 by Trevor Jones, posted in Compliance, ConfigMgr, Powershell, SCCM

Some organisations like to disable Java applets from running in a web browser for tighter security. This can be done with group policy, but in our organisation I already manage Java settings across the enterprise with Configuration Manager’s Compliance Settings (as documented in my solution guide for Java), so I decided to use a Compliance Setting for this also.

The best way to disable Java in the browser is simply to deselect the “Enable Java content in the browser” setting in the Java Control Panel:

Doing that will change a fair number of registry keys, too many to manage or set individually. Thankfully, you can achieve the same result using the following command from your Java installation files:

“C:\Program Files\Java\<java version>\bin\ssvagent.exe” -disablewebjava

When Java in the browser is disabled, the following key is set in the registry, which we can use as a way of programatically detecting whether Java in the browser has been enabled or not:

Key: HKLM:\SOFTWARE\Oracle\JavaDeploy
Name: WebDeployJava
Value: disabled

Now I create a new setting in my “Java Settings” configuration item, which I’ll call “Java WebDeploy”:

In this setting I use two PowerShell scripts, one for discovery, and one for remediation, which you can find below. The discovery script will use the registry key above to determine whether Java has been disabled in the browser or not, and the remediation script will run the command that disables web Java for all installed Java versions.

For my compliance rule, I simply use the value “Compliant” which is outputted by the script:

Once this setting has been deployed in a baseline to your computers, Java will be disabled in web browsers for each machine that has Java installed in the default locations. Should a user manually enable it from the Java control panel, the ConfigMgr client will disable it again according to the compliance evaluation schedule you have defined.

Discovery Script


$key = "HKLM:\SOFTWARE\Oracle\JavaDeploy"
if (Test-Path $key)
    {
        if ((Get-ItemProperty -Path $key -Name WebDeployJava -ErrorAction SilentlyContinue | Select -ExpandProperty WebDeployJava) -ne "disabled")
            {
                Write-Host "Not Compliant"
            }
        Else {write-host "Compliant"}
    }
else {write-host "Compliant"}

Remediation Script


$JavaInstallPaths = @()

if (${env:ProgramFiles(x86)})
    {
        $path = "${env:ProgramFiles(x86)}\Java"
        if (Test-Path $path)
            {
                $JavaInstall = Get-ChildItem -Path "${env:ProgramFiles(x86)}\Java" | select -ExpandProperty FullName

            }
