Desktop Fileset Timed Events

Description

Filesets have the option to set an activation time, but what about items based upon timing of day, for example, rather than a dedicated date.

image.png

Policy Blocker Scripts are really designed to pause management of clients.  However, with some clever use, a Policy Blocker Script can provide us with some assistance.  This script type runs every 5 minutes on clients.  Although the intention is to pause management until the script reports an exit status of 0, the 5 minute continual trigger can be leveraged.

Extending this with Custom Fields, it is possible to build out a desired outcome.

Ingredients

macOS Windows
Policy - Timed Event macOS.fileset.zip Policy - Timed Event Windows.fileset.zip

Directions

Alter the Custom Fields values for Inactive and Active times to suit.  Time is set using hours, minutes and seconds.  E.g.

Desired Time (HH:MM) Custom Field Value (HHMMSS not including leading zeros)
09:30 93000
12:55 125500
18:00 180000

If changing the Custom Field value for a device which is already running the policy, 2 subsequent Model Updates will need to be received by the client, if looking for a more ‘immediate’ result.  The blocker script holds the client until success.  This means, during a Model Update, the blocker will run before the new Custom Field Value will be read by the device.  As such, only after a subsequent update (or inventory) will the blocker script be aware of the new Custom Field value.  Custom Fields will naturally update on devices with inventory, but this is less frequent.

Time Order

Times can be either way around. 

Examples:

Consider working hours to begin at 08:30 and end at 18:00

Example 1

An item should only be considered outside of standard working hours.

image.png

Example 2

Alternatively, an item should be considered during working hours:

image.png

Imported Custom Fields are disabled for all devices by default.  Once tested, consider using the option to assign to all devices for each Custom Field imported.  The file provided contains all 3 Custom Fields.

image.png

Smart Groups

A third Custom Field holds a true/false value.  This value may be used with a Smart Group query, to determine if an item should be associated at this time or not.

This Custom Field is set to use custom_bool_01.  If this is already in use, an alternate Custom Bool number should be utilised instead.  This is editable through the Scripts Environment Variables. 

The script uses the following method to set these values.

https://kb.filewave.com/books/custom-fields/page/add-filewave-custom-inventory-fields-remotely-using-a-fileset

Example

An update to Firefox needs to occur after 17:00 or before 09:30

Between these times, the 3rd Custom Field ‘Active Time’ should be False/0.  Outside of these times, the ‘Active Time’ Custom Field should be True/1.  

image.png

Smart Group can be based upon the following:

Do not just use the active time, unless intentional.  Devices will continually enter and leave the Smart Group if this is set to only use the Active Time, each day.  If an item is associated in this way, associated Filesets will trigger every time the device enters the group.

Deeper Dive

The Policy Blocker script has 2 considerations initially:

This means there is a time beyond which the desired action may occur and a time beyond which the action should not occur and this needs to be compared with the current time.

The enable/disable active times are provided by way of Executable Environments.  Taking this a step further, these times are defined using Administrator Custom Fields.  This way the times can more easily be altered if required.

A third Custom Field is being used to indicate if the current time is one of activity allowance or not, but this time a Client Command Line Custom Field.

Client Command Line Custom Fields are stored locally on the device and then this value is available to the server, both for visibility, but can also be used in queries, for Smart Groups.

image.png

Client Command Liine Custom Fields may be altered in FileWave Central Admin App, however, as soon as the device checks back inventory, the value from the client will be pushed back to the server.

Apple Profiles & Dependencies

Description

Dependencies offer a structure for Fileset installations, ensuring one or more Filesets are installed prior to one or more other Filesets.  This works great, apart from where Apple MDM Filesets are involved.

Fileset Activation Quick Re-cap

Standard Fileset

  1. Client checks-in.
  2. Manifest is observed
  3. New items are pushed to device and activate

Apple MDM Fileset (Profiles)

  1. APNs request sent to Apple
  2. Device pulls queued APNs requests from Apple
  3. For each APNs request, device reaches out to relevant servers, for MDM requests, this is the FileWave Server
  4. Device checks-in
  5. Queued MDM commands are pushed to device, e.g. InstallProfile
  6. Profile instals

For standard Filesets, FileWave is in control of the communication.  However, for Apple MDM, there is an unknown amount of delay until the Profile is installed.

The Issue

Since Filesets are installed sequentially, if a Fileset were allowed to depend upon an Apple MDM Fileset, the client would be held waiting for an unknown period time, preventing other Filesets and configuration from actioning.  For this reason, Apple MDM Filesets can only depend on a different Fileset type and not the other way around.

Requirement Scripts

Requirement Scripts allow a Fileset to fail, let the client continue and then 2 minutes later try the requirement again.  The Requirement Script will continue with this process, whilst there is a non-zero exit code.  By way of this process, the Requirement Script gives the ability to delay the installation of the Fileset, until any required Profiles are installed beforehand.

Ingredients

Profile Dependency Fileset Template.fileset.zip

Directions

Download the Fileset, import into FileWave and edit to match requirements.  Select the ‘check_for_profile.sh’ script and click ‘Get Info’:

Pasted Graphic 14.png

The Launch Arguments will initially appear empty.

Pasted Graphic 16.png

For each Profile that needs to be considered for installation prior to this Fileset, its ID must be added to the list of Launch Arguments (one entry per Profile ID).  Profile IDs can be obtained from within the Payload details of the Profile Filesets.

For eah Profile that must be installed, open the Profile for editing, highlight the Identifier and copy.


Pasted Graphic 15.png

Copy these IDs into the LaunchArguments of the Fileset.  Example below shows 5 Profile IDs added for a Microsoft Defender Installer.

Pasted Graphic 13.png

The script allows for the idea of either by way of an Environment Variable (all_or_one).  Set the value appropriately:

all All of the listed Profiles must be installed prior to the Fileset becoming active.
one At least one of the included Profiles must be installed prior to the Fileset becoming active

The below, shows a Fileset set to require all Profiles are installed, before Fileset activation for the same Microsoft Defender example:

Pasted Graphic 12.png

With this set, add any additional installers into the Fileset, that would need to be installed, once the provided Profiles are installed.

Create a Fileset Group and add this Fileset and all necessary Profiles to the same group (not necessary, but somewhat neater to manage)

For example:


Pasted Graphic 17.png

Associate the Fileset Group, test and then rollout to more devices once happy.

This Fileset is particular useful with Apple TCC Privacy Settings Profiles.  Privacy settings provide access permissions for software to function.  However, typically these Profiles need to be installed before the process that they are allowing is started.  This means, if the software is allowed to instal before the Profile is installed, the software process would need restarting after the Profile is installed.  The above Fileset offers the solution around this, where the Fileset will only attempt download and installation once the Profile is in place.

Policy Loops

What

A policy loop happens when a Smart Group's criteria are changed by the Fileset or association assigned to that same Smart Group. The device enters the group, receives an action, then no longer matches the criteria. On the next Smart Group refresh it may leave the group, remove or change the Fileset, and then qualify again. The result can be repeated installs, removals, downgrades, or confusing association churn.

Example Filesets used in policy loop scenarios

When/Why

The risk is highest when group membership is based on the exact state that the Fileset changes, such as an application version, installed-file presence, or another inventory value that changes immediately after activation.

Example 1: version-based installer loop

Imagine a PKG macOS installer Fileset for an app called CLU.app, version 1.0. It is associated to all devices based on two criteria:

Once the software is installed, those devices no longer belong to the group because version 1.0 is now installed.

A new version of the software is released: CLU.app version 1.1. A new association is created with a different Smart Group using similar criteria:

Devices running version 1.0 will join the new Smart Group at the next refresh. The new Fileset activates, the software upgrades from 1.0 to 1.1, and the devices then leave the version 1.1 group because they no longer match its criteria.

The problem appears on the next Smart Group refresh. Because version 1.0 is no longer installed, those same devices may qualify again for the older version 1.0 Smart Group. If the older PKG can install over the newer version, the software is downgraded back to 1.0. Once that happens, the device qualifies again for the 1.1 group, and the cycle repeats.

This is a policy loop: the device keeps moving between groups because each successful deployment changes the criteria used to target the next deployment.

Example 2: self-healing Fileset loop

The same principle can happen with one group. In this example, CLU.exe version 1.0 is delivered as a file-level self-healing Fileset for Windows.

The Smart Group criteria are:

Smart Group criteria for Windows devices without the CLU application

Windows devices without the software enter the Smart Group, receive the Fileset, and report that the software is now installed. At the next Smart Group refresh, those devices no longer meet the criteria and leave the group.

Because the Fileset is self-healing, leaving the association can remove the software. The user loses the application, the next refresh sees the device as missing the software again, and the device re-enters the group. The software is then installed again, removed again, and the loop continues.

Avoiding the loop

The answer is not to avoid Smart Groups or self-healing Filesets. Both are core FileWave workflows. The important part is to design criteria so a successful deployment does not immediately undo its own targeting logic.

Fast Smart Group Evaluation can be useful for time-sensitive membership changes, but it does not fix a policy loop. If the criteria are unstable, faster evaluation can simply make the loop show up sooner.

Updating 3rd Party Software

What

Naturally devices require software and that software needs updating.  The question is how.

For managed software, e.g. Apple VPP Apps, updates occur automatically, but other software deployed using PKG, MSI, EXE or file level Filesets then what happens.  Essentially, there are a couple of key choices.

Some software attempts to auto update, which may or may not work, in particularly when users are not admins, whilst other software will always require updates pushed out.

image.png

Why

Back to the choice.  Allow software to auto update or prevent such activity and choose to build new Fileets to push out updates.  Making that choice, though, can be impacted by other factors.

For example:

How

Those are some considerations.  Now to consider some finer details.

Denying AutoUpdates

For software that has no autoupdates, this is already a consideration, but denying updates takes some greater work.  Firstly, a requirement to locate how the update works and then how to prevent it.

image.png

Most software vendors are likely to have either a Windows registry entry or a macOS plist preference file that can be configured to prevent the updates.  Identifying the file to alter and the values to set, in some instances can be easy to address.  In fact, many other Admins often post these settings or they may be available from vendors.  However, sometimes this information isn’t readily available.

image.png

Various methods exist, but generally, the process is look at files before and after making preference changes made available through the software GUI if available.  Fileset Magic is one method to assist with this process.  This option of the FileWave application takes a snapshot of the device and then after changes are made, a second snapshot is taken.  It is then a case of comparing the before and after to see what has changed.

Allowing AutoUpdates

One key question is, does micro management of updates of all applications really improve management of devices.  Many applications are not business critical or a bad update could easily have minimal impact.  With that in mind, why not allow updates.  Indeed, Apple VPP Apps leave little choice.  Of course, just making that decision does not mean auto updates are on by default.  As such, the same process to calculate how to disable updates may need to be actioned to work out how to enable updates.

Add to this, as eluded to prior, will the auto update work if the user is not an Admin.  This needs to be tested, but if not, then the same process used for denying updates would likely be required.

Considerations

For either method, there are some additional considerations, which mostly centre around self-healing.

Denying Autoupdates

When using a file level Fileset to deploy software, files should be set as self-healing. 

image.png

Not only does this ensure the most efficient delivery of files from server to devices, it adds some greater benefits.  When the association of the new version is associated, in the same Model, the older version should be disassociated.  

If both Filesets are left associated, updated files will be replaced, whilst new files will be pushed to devices, however what about files that the software no longer uses.  If the older Fileset is not disassociated, these files will be left behind.  Although this may seem harmless enough, actually they can be very damaging.  Developers of software would not expect those files to be in existence with the new application and with thousands of lines of code, it could be easy enough that these files still have references and could cause havoc with the newer version.

Allowing AutoUpdates

So, how about handling software where the autoupdates is allowed to occur.  In this instance, if file level Filesets are used to deploy the application, self-healing would be completely the wrong choice.

When software autoupdates, files will be altered.  When a verification occurs, any altered files set for self-healing, will be replaced with the older files.  Although clearly undesirable, this isn’t the same as downgrading the software, such that it would still function.  Self-healing will also return any files that were removed by the updater.  This brings back the condition of files unexpectedly installed, which again could cause the software to act irregular or not even start.  As such, Ignore at Verify would be the ideal selection.

image.png

Ignore at Verify brings about 2 additional items for attention.

Un-installing.

Un-installers can come in differing forms, one of course is by way of self-healing.  However, using the allowed auto-updater example, self-healing is not an option.  This means an alternate method would be required to remove the software.  Of course, FileWave can be used to achieve this, for example, with un-installer scripts.

Rollback

Where software is auto updating, the only version available in FileWave will likely be the same version originally pushed (unless updated more recently as a Fileset).  Therefore, if there was a need to rollback to a prior version, som additional work would be required, which would take time before being deployable.

Overview

Each method has its own merits, but being aware of the pros and cons and how to deal with these, provides the armoury for successful application management.

Un-install Filesets

What

When software is no longer needed, the removal method depends on how it was originally deployed. This article outlines the common FileWave uninstall paths and where a custom uninstaller is still required.

Options

Self-Healing

If a Fileset uses Self Healing and Download if Missing for tracked files, disassociating the Fileset removes the files that are part of that Fileset.

MSI

Windows MSI Filesets are different because MSI packages can expose an uninstall action. When the Fileset is configured to use that feature, disassociating the Fileset can trigger the MSI uninstaller.

image.png

PKG/EXE

PKG and EXE installers do not provide the same built-in uninstall behavior as MSI packages. In many cases the Fileset only tracks the installer itself, not every file created by the installation. If the software vendor does not provide a separate uninstall PKG, EXE, or script, you will usually need to build your own removal script.

Apple VPP & Android Play Store

Disassociating these Filesets sends a command to remove the application.

Other Files

Applications often create supporting files after first launch, such as preferences, caches, or user data. If you need to remove those items too, you will normally need a separate cleanup method.

Why

Removing unused software helps keep devices clean, reduces confusion for users, and can support security and license-management goals.

When

Knowing how to uninstall software is only half of the job. You also need to decide when the uninstall should run.

At first glance it may seem natural to place a pre- or post-uninstaller script inside the same Fileset as the installer. That can work against you when the application is updated.

As vendors release updates, you may replace the installer with a new Fileset or a new Fileset revision. Self-Healing handles matching files cleanly during that swap, but any uninstall script inside the installer Fileset can also run during the change, which is usually not what you want.

How

A common way to control this is to separate installation and removal logic by using a Fileset Group.

In the example below, the Fileset Group for Microsoft Defender includes the installer Fileset, related profiles, and a separate uninstaller Fileset. Devices are associated with the Fileset Group, not directly with the uninstaller.

Pasted Graphic 18.png

The uninstaller Fileset uses a pre-uninstallation script:

Pasted Graphic 20.png

This makes installer updates straightforward. You can replace the installer Fileset or swap revisions inside the group without firing the uninstall. The uninstall runs only when the Fileset Group itself is disassociated from the device.

PKG/EXE Un-installers

If a vendor supplies an uninstall PKG, it is usually cleaner to place that PKG in an otherwise empty Fileset and trigger it from an uninstall script, similar to the Microsoft Defender example above.

Trying to auto-associate a separate uninstall PKG exactly when the original installer is disassociated quickly becomes hard to manage.

EXE-based uninstallers have the same issue. A practical pattern is to upload the uninstall EXE to an empty Fileset and call it from a pre- or post-uninstallation script.

Pasted Graphic 21.png

This gives you a dedicated uninstaller Fileset that can be added to a Fileset Group and triggered only when you actually want removal to occur.

Inventory Items in Scripts

What

When

Internal Name of an Inventory Item may be located from the Inventory Query Editor.  Example shows the Internal Name: ‘device_product_name’

Pasted Graphic 29.png

This may then be added into a Script, by way of either a Launch Argument or Environment Variable

Pasted Graphic 30.png

But, which should be used?

How

In some respects it does not matter which is used, however, for easy reference consider the following:

Built-In Inventory

In general, recommendation here is that of Environment Variables.  This makes reading the script easier without having to redefine new names within the script for Launch Argument positions.

For example:

Pasted Graphic 31.png

Could be referenced in a script as:

macOS shell echo $1
Windows Powershell echo $args[0]

But to make the parameters more easily recognisable for anyone reading the script, it could be desirable to name them:

macOS shell 
product_name=“$1”
echo $product_name
Windows Powershell 
$product_name=“$args[0]”
echo $product_name

References to the provided inventory parameters in the script now makes more sense, but as mentioned, Environment Variables take this a step further:

Pasted Graphic 32.png

A variable name is already defined and this can be referenced in the script directly

echo $product_name

Improvements

First Improvement

To improve the readability of the script further, consider setting the variable name to match the value, e.g:

Pasted Graphic 33.png

echo $device_product_name

Second Improvement

When referencing a Custom Field in a script, it could be referenced in one of two ways.  

Example Custom Field: State

Pasted Graphic 39.png

Note, the description has been used to indicate this is a Custom Field.  Inventory Query editor shows Description.

This could be referenced with:

Pasted Graphic 41.png

and

echo $state

However, there is a built-in Inventory Item called State.  So there are now two Internal Names of ‘state’

Pasted Graphic 38.png

Pasted Graphic 37.png

The above scripted example for 'state' would actually report the built-in value, not the Custom Field.  There is, though, a hidden prefix that can be used.  

This Custom Field could be referenced as either:

The latter prevents unexpected collusion with the matching Internal Name.  Hence, to make the parameters more obvious when reading…

Pasted Graphic 40.png

echo $custom_fields_state
echo $internal_device_product_name

Notice, despite no prefix existing for built-in Inventory Items, by including a prefix for both variables in the Environment Variables definitions, reading the script will be much clearer.

Anyone reading the script is now aware that state is a Custom Field, without having to cross reference anything.  Likewise, the reader also is aware that the device_product_name also comes from Inventory, again, without any cross reference necessary.

Unknown Inventory

Not all Inventory Items are available as parameters.

The FileWave Client builds out the report of items to inventory and return to server.  Additionally, all Custom Fields, including those server-side (Administrator Custom Fields), are available to the client.  However, inventory returned by MDM is not available, since the client is unaware of these values, they are pure server-side.

Script Logging

What

For scripts added to FileWave Filesets using the Script view, logging is enabled by default.

Pasted Graphic 59.png

When

Each time a Script (as built above) is actioned on a device, a log file is created or added to, with anything that the script outputs.  The logs of these Scripts are located in the following directories, within subfolders named after the Fileset ID:

macOS

Windows

Example:

macOS example, but the principle is the same for Windows.

Consider this simple shell script that runs a command to output the username that ran the command:

Pasted Graphic 60.png

On running the command, the user running the command will be reported.  For example, running this locally on a device might reply:

% whoami
sholden

Viewing the log generated by FileWave:

# cat /private/var/log/fwcld/54421/whoami.sh.log
----------------------- HEADER - Date: (Fri Dec 15 2023) - Time: (16:40:21) -----------------------

----------------------- FOOTER - Date: (Fri Dec 15 2023) - Time: (16:40:22) - Exit code: (0) -----------------------

The output presents:

Improvement

The Script may or may not provide output, depending upon the command used.  However, why not add additional echo commands (or similar) to output extra details to provide more information from the script running.

Here is an example of a Fileset Requirement Script, waiting for confirmation of a Profile to be installed before activating the Fileset:

Pasted Graphic 61.png

The script is outputting additional information, showing the ID of the Profile, found or not.  On success, exit 0, else exit 1.

Requirement Scripts will retry every 2 minutes, until successful, unless coded otherwise

----------------------- FOOTER - Date: (Thu Jul 31 2024) - Time: (11:05:12) - Exit code: (0) -----------------------

On first attempt, the log shows two Profiles were searched and not found, with the script exiting a value of 1.  On second attempt, the first Profile ID is now showing as installed and the script exited with a value of 0.

No Logs

Some scripts ran through FileWave, e.g. Policy Blocker Scripts, do not provide logs, with some mention in the Client Log alone, that the Script ran.

However, it is entirely possible to choose to create a custom log file within a script, for any script, and echo any output desired to provide additional logging.

Consider how the script will grow and how to either overwrite or append appropriately.

Profile Payload Planning

What

That’s the fundamentals of Profiles in a nutshell, but there is more consideration.

Key aspects:

Example Profile with multiple Payloads:

Pasted Graphic 22.png

For the same above Payload, the Settings show:

Pasted Graphic 23.png

Apple’s implementation is such, that only one local user can be managed (the first user after enrolment).  However, any amount of directory users can be managed.  This restriction applies to User set Profiles only.

Not all Payload types can be User or System.  Some may only be User or only System, rather than the choice.  From the screenshot above, the Settings show System is the only choice and is therefore greyed out.

Possibly, one of the most important consideration:

Where multiple Profiles are assigned which contain the same Payload type (but differing settings), Apple do not guarantee the experience.  There used to be a suggestion for restrictive Payload settings, the most restrictive wins, but other Payload types have always had this mention.

How

Firstly, overlapping Payloads should be avoided, to ensure experience is by design, not luck.

Next, from the above, Profiles can contain many Payloads, but should they?  Consider:

Undesired Experience:

More items in the Profile makes it harder to identify anything occurring that is undesired.

Removing the undesired experience temporarily, whilst identifying, involves removing the entire Profile, which could easily be undesirable in its own right.  By creating multiple Profiles with different Payloads, instead of one massive Profile with lots of Payloads, makes identifying and resolving unexpected experiences, much more easily with less impact.

Force Reinstall

This option can be desirable for a few reasons, but consider this example:

An example Web Clip Payload, using a Custom Field to populate the value:

Pasted Graphic 24.png


When a Profile is altered, FileWave will note the Profile as Modified and the Profile will be redelivered with the new settings.  However, when changing Custom Field or Inventory values, there is no change to the Profile.  The Payload referencing the Custom Field or Inventory item is still referencing this, it is only during delivery that the value is noted and entered in the Profile.  As such, if the referenced Custom Field or Inventory values are altered for devices, the current Profile will need to be reinstalled.  A ‘Force Reinstall’ will ensure this occurs, but two things occur from this action.  The current Profile is removed and the updated Profile is installed.  Consider, what is the consequence of Profile removal?

With the above in mind, always consider what is being included in a Profile and therefore keep each Profile lean in content; try not to overload too many Payloads into one Profile.

Overlapping Payloads

What is an overlapping Payload.  This is when two or more Profiles are trying to manage the same thing, but with different settings.  This shouldn’t be confused with multiple allowed Payloads.

For example:

Profiles to manage the Dock.  One Profile sets the dock on the right and the other on the left.  This is overlapping and should be avoided:

Pasted Graphic 25.png

Pasted Graphic 26.png

If both of the above were assigned to a device, how could the device possible determine which should be obeyed?

Profile to provide certificates.  One Profile provides one certificate and another Profile provides a different certificate.  This isn’t overlapping.  Providing multiple certificates is desirable and need not be from one single Profile.

User vs System

Within the settings of Profiles is an option to define whether the Profile should apply to users or system.  Some Payloads may be set as User or System only, but not either, whilst others may be either.  A Profile must have a setting, so a default will be used when a Profile Payload is first added.  Always check to confirm it is set as desired.

A Profile may only have one setting applied.  FileWave will therefore prevent the addition of a User only Payload to a Profile already containing another Payload set as System.  However, where Payloads may be either, if a Profile already contains a Payload, any additional Payloads that can be added will all be set with the same setting.

For example:

It can be seen that the Login Window is System only, yet the Dock Payload could be either

The Settings remain as System and the applied Dock Payload will therefore be set for the System and not User.  If a Dock Profile of User were required, it should not be included in a Profile that already contains a Payload that is set as System.

Why

Should all of the above be of consideration?  Why would User be chosen over System?  If System will work for all users, why not just set all Profiles as System where possible.  However, what if the settings included were only for users, but not for a hidden Admin account.  This local admin account is not managed by MDM.  By setting System level, any Profiles built this way will impact this user, along with the managed local user and any directory users.  This may be undesirable.  Passcode policy could be an example.

Some Payload types require certain types of enrolment.  Many Payload settings require Supervision, for example.  macOS devices managed via User Enrolment, do not qualify as Supervised.

Planning

The above comes down to planning.

Profiles could contain multiple Payloads based upon functionality and for User or System determined targeting.  Who needs to be managed?  Local user (all or just managed) and/or directory users.

Consider the impact if a Profile were ‘Force Reinstalled’ or if it was deemed necessary to temporarily remove the association to one or more devices, for whatever reason.

Also give thought to how devices will be purchased and enrolled depending upon what needs to be managed.  Using a BYOD scheme and only using User Enrolment will greatly reduce what can be managed, whist ADE(DEP) gives the maximum amount of control through Profiles.

Will the choice made, incur additional concerns over security, if desired management cannot be achieved?

Inventory Items in Profiles

What

When

Internal Name of an Inventory Item may be located from the Inventory Query Editor.  Example shows the Internal Name: ‘device_product_name’

This may be added into a Profile, effectively customising the Profile per device or user:

Custom Fields

Associated Custom Fields may also be used with Payloads settings of Profiles.  Extending the above example, consider a Custom Field for Asset Tag:

Profile Payload

Improvement

When referencing a Custom Field in a Profile Payload, it could be referenced in one of two ways.  From the above example, it could be either:

The additional prefix indicates more clearly that this is a Custom Field Inventory Item.  If there was an Inventory Item with a matching name provided by FileWave, the first item in the list would report the provided Inventory Item value for the device and not the Custom Field.

For demonstration, imagine creating a Custom Field called 'My Device Product Name' with Internal Name: device_product_name. 

Pasted Graphic 54.png

There are now two Inventory Items with the Internal Name: device_product_name:

and

Pasted Graphic 52.png

With the values:

Altering the above example Lock Message to use both of these:

Pasted Graphic 57.png

The device clearly demonstrates how the value without a prefix uses the FileWave provided Custom Field value:

Pasted Graphic 58.png

To prevent confusion with overlapping Inventory Items between Custom Field and built-in Inventory, always consider using the prefix for Custom Fields

User Customisation

Although FileWave doesn't manage users, if users are associated with devices, this extends the ability to customise Profiles for users.

User details from enrolment may be used, but to extend beyond this, LDAP servers set for extraction can greatly increase the Inventory Items available for Parameters via LDAP Custom Fields.

An example of Profile customisation for users:

One Profile can therefore be used for multiple devices, tailoring the Payload to the users of those devices.

Android Policy Planning

What

Android Policies provide a method of configuration.

Key aspects:

Example Policy, allowing Developer Settings, including setting Debug:

Pasted Graphic 28.png

Possibly, one of the most important consideration:

Where multiple Profiles are assigned which contain the same Payload type (but differing settings), what could the possible expectation of experience be on the end device with these overlapping Policy Settings, noting that Apps potentially have their own settings also?

How

Firstly, overlapping Policies should be avoided, to ensure experience is by design, not luck.

Next, as mentioned above, Policies can contain many configurations, but should they?  Consider:

Undesired Experience:

More items in the Policy makes it harder to identify anything occurring that is undesired.

Removing the undesired experience temporarily, whilst identifying, may involve removing the entire Policy, which could easily be undesirable in its own right.  By creating multiple Policies with different settings, instead of one massive Policy containing everything, makes identifying and resolving unexpected experiences, much easier with less impact.

Remove/Reinstall

Perhaps something doesn’t appear to be working as intended.  To confirm the Policy, it may be desirable to remove that Policy, but what if other items in the Policy should not be removed, e.g. Certificates.  Separating settings based upon functionality should help alleviate this potential problem.

Overlapping Policies

What is an overlapping Policy.  This is when two or more Policies are trying to manage the same thing, but with different settings.  This shouldn’t be confused with multiple allowed Policies.

Greater detail on this can be found in our KB:

https://kb.filewave.com/books/android/page/android-emm-policies-and-permissions

In essence, overlapping Policies should be avoided.  An experience may appear correct, due to an overlap.  If one of the Polices were removed, the experience may unexpectedly alter if there was no awareness of this.

A Policy to provide certificates is an example of a potential multiple allowed Policy.  One Policy provides one certificate and another Policy provides a different certificate.

Planning

The above comes down to planning.

Policies could contain multiple settings based upon functionality.

Consider the impact if there was a requirement to remove and subsequently reinstate a Policy, for whatever reason.

Also give thought to how devices will be purchased and enrolled depending upon what needs to be managed.  Enrolment types can also impact items managed.

Will the choice made, incur additional concerns over security, if desired management cannot be achieved?

OS Patching

Best Practice Guide: Software Update Deployment (16.0+)

What

With FileWave Version 16+, the system for patching devices with Operating system updates has been overhauled, and your current workflows likely should be as well.  This article will review how you can best cleanup, reorganize, and overall simplify your patch management processes.

Note that you want to avoid assigning Windows OS updates to pre-16.0.0 clients because they will not function correctly. You can simply add a criteria to your SmartGroup to check if the "FileWave Client Version" begins with "16." and that would protect you until you can work to upgrade all of your devices.

Also note that Windows OS updates from before FileWave 16 should be purged from your server to free up disk space, and because they will not function correctly. This transition from the old format to this new format should be a one-time exercise to remove the old style of Windows OS updates and ensure your clients are upgraded to FileWave 16.0 or higher.

When/Why

Patch management of devices in your environment is the most important thing an IT manager does in almost every single organization.  FileWave 16+ does operating system patching differently than before, but we feel confident if you follow this guide, and tailor it to your environment, that you'll find the new solution much more elegant and relatively care free.

For the purposes of this document, we'll use an example of a common deployment scenario, Alpha, Beta, then Production patching.  That is, a system where you fist test new patches against a small set of devices (your alpha group) to ensure patches work without issue.  Later, you would deploy to the larger beta group to ensure distribution is good.  Only when both Alpha and Beta are good would you deploy to Production.  

In some environments, folks go straight from test to production directly for OS patching.  This will work fine as well, and you can tailor the below accordingly.

How

This concept was discussed on Discord so you can check out this video as well as the rest of this article to get more details;

First it is important that your account has permissions to perform these actions. In Assistants -> Manage Administrators as shown in the below image notice if you have Manage Updates and Configure Automation Rules enabled. 

Google Chrome 2025-10-02 11.47.17.png

As stated above, in our example organization, we patch as follows:

  1. Each Monday we evaluate newly offered patches, and if we want to deploy them to test, we assign them to our Alpha group.
  2. On Wednesday of each week, if Alpha testing was good, we'll assign these same patches to the Beta group.
  3. And on the following Monday, if all is still well, we assign the same patches to our Production groups.

But if we are starting from scratch, how best do we do this?  We need three sets of objects to make all of the above happen.  Device groups, fileset groups, and deployments.

Note: We are using Deployments here instead of associations on purpose.  Deployments maintain their settings regardless of "new" content, and are much easier to use to add device exceptions (i.e. in this test, exclude Device A)

Device Groups

The device groups will be built like this:

image.png

The top level group is only for organizational purposes, and includes three groups.  There is a manual group for Alpha Devices and for Beta Devices (we'll put select devices in each group manually).  The Production groups are smart groups based on operating systems we manage.  In our case, Apple devices and Windows.

Note that once these groups are established, we will likely not need to edit them regularly.  The "Production" smart group definition is shown below for Windows and then Apple. It's important for server performance to group them this way.

Fileset Groups

FileWave Version 16+ makes bulk-creating and storing patches MUCH easier.  For our example patching workflow we are going to create Fileset groups to match our device groups.  Note again that we've added a top level group for organizational purposes.

image.png

Deployments

Deployments are the way we'll relate the other two building blocks above.  That is, we'll use deployments to relate Patches to Devices using the fileset groups and device groups we built above.  Alpha patches to Alpha devices, etc.  Notice that the "Beta" assignment contains both Alpha and Beta Groups...we do that because they are manual groups and we want to make sure those devices all receive the assignments.  The Production deployment doesn't need that, because it is by platform and covers all devices no matter what groups they are in.

image.png

Note that the assignments above are critical to the workflow, and you'll see that in the How to Use section below.

How to Use?

Now that we have our building blocks in place, we can start patching.  Let's pretend that it is Monday morning of a new week.  Let's go into the Software Updates view to see what new patches are available to us:

Apple Patches

Windows Patches

And in our environment it is a lot of patches indeed, since it is the first time we are setting up the mechanism.  But don't worry, it is now easy to create everything at once, and there are several filters to help you.  Examples:

Let's assume for now though that "we want to patch everything".

Patch Creation (Alpha)

Because we always start with our Alpha groups, that is the Fileset group location we'll use every Monday (and any other time we create new patch Filesets).  Creating the Filesets couldn't be simpler...we'll just select them all, right-click, choose create, and then choose the destination (our Alpha Fileset groups)

Note that we put ALL patches for Windows in the same Windows Fileset group, and all Apple patches in the Apple Fileset group...that is on purpose.  As soon as we update model, all "Alpha" patches for all "Alpha" devices will be assigned, and start to deploy...it's as easy as that.

Patch Assignment (Beta and Production) 

Because we always start with our Alpha group, we never have to "create" patches for the Beta testers or Production users.  On our "Wednesday" Beta testing the ONLY thing we have to do is MOVE the filesets from our Alpha Fileset Group to our Beta Fileset Group.  And the following Monday we'll move patches from Beta to Production.  Job well done.

Tracking Progress

And, when evaluating how your patching is going, remember there is a new view for any individual software update where you can see assignment (and results) from all devices.

Windows BIOS/UEFI Firmware and Driver Updates

The latest Windows Software Update filesets now include BIOS/UEFI firmware updates from certain OEM vendors (e.g., Dell, HP, Lenovo). While these updates may appear alongside OS patches, please be careful when deploying. 

The latest Windows Software Update filesets now also includes third-party driver updates, such as those for monitors, audio devices, and peripheral hardware. While these updates can improve compatibility and stability, they often have the following impact:

To maintain a smooth user experience and prevent unplanned reboots, you may want to deploy driver updates via Self-Service Kiosk instead of automatic enforcement.
