You create a profile, and it includes all the settings you entered. The next step is to deploy or 'assign' the profile to your user or device groups. When it's assigned, the users and devices receive your profile, and the settings you entered are applied.

This article shows you how to assign a profile, and includes some information on using scope tags on your profiles.

Note

When a profile is removed or no longer assigned to a device, different things can happen, depending on the settings in the profile. The settings are based on CSPs, and each CSP can handle the profile removal differently. For example, a setting might keep the existing value, and not revert back to a default value. The behavior is controlled by each CSP in the operating system. For a list of Windows CSPs, see configuration service provider (CSP) reference.

To change a setting to a different value, create a new profile, configure the setting to Not configured, and assign the profile. Once applied to the device, users should have control to change the setting to their preferred value.

When configuring these settings, we suggest deploying to a pilot group. For more Intune rollout advice, see create a rollout plan.

Before you begin

Be sure you have the correct role to assign profiles. For more information, see Role-based access control (RBAC) with Microsoft Intune.

Assign a device profile

Sign in to the Microsoft Endpoint Manager admin center.
Select Devices > Configuration profiles. All the profiles are listed.
Select the profile you want to assign > Properties > Assignments > Edit:
Select Included groups or Excluded groups, and then choose Select groups to include. When you select your groups, you're choosing an Azure AD group. To select multiple groups, hold down the Ctrl key, and select your groups.
Select Review + Save. This step doesn't assign your profile.
Select Save. When you save, your profile is assigned. Your groups will receive your profile settings when the devices check in with the Intune service.

Use scope tags or applicability rules

When you create or update a profile, you can also add scope tags and applicability rules to the profile.

Scope tags are a great way to filter profiles to specific groups, such as US-NC IT Team or JohnGlenn_ITDepartment. Use RBAC and scope tags for distributed IT has more information.

On Windows 10 devices, you can add applicability rules so the profile only applies to a specific OS version or a specific Windows edition. Applicability rules has more information.

User groups vs. device groups

Many users ask when to use user groups and when to use device groups. The answer depends on your goal. Here's some guidance to get you started.

Device groups

If you want to apply settings on a device, regardless of who's signed in, then assign your profiles to a devices group. Settings applied to device groups always go with the device, not the user.

For example:

Device groups are useful for managing devices that don't have a dedicated user. For example, you have devices that print tickets, scan inventory, are shared by shift workers, are assigned to a specific warehouse, and so on. Put these devices in a devices group, and assign your profiles to this devices group.
You create a Device Firmware Configuration Interface (DFCI) Intune profile that updates settings in the BIOS. For example, you configure this profile to disable the device camera, or lock down the boot options to prevent users from booting up another OS. This profile is a good scenario to assign to a devices group.
On some specific Windows devices, you always want to control some Microsoft Edge settings, regardless of who's using the device. For example, you want to block all downloads, limit all cookies to the current browsing session, and delete the browsing history. For this scenario, put these specific Windows devices in a devices group. Then, create an Administrative Template in Intune, add these device settings, and then assign this profile to the devices group.

To summarize, use device groups when you don't care who's signed in on the device, or if anyone signs in. You want your settings to always be on the device.

User groups

Profile settings applied to user groups always go with the user, and go with the user when signed in to their many devices. It's normal for users to have many devices, such as a Surface Pro for work, and a personal iOS/iPadOS device. And, it's normal for a person to access email and other organization resources from these devices.

Follow this general rule: If a feature belongs to a user, such as email or user certificates, then assign to user groups.

For example:

You want to put a Help Desk icon for all users on all their devices. In this scenario, put these users in a users group, and assign your Help Desk icon profile to this users group.
A user receives a new organization-owned device. The user signs in to the device with their domain account. The device is automatically registered in Azure AD, and automatically managed by Intune. This profile is a good scenario to assign to a users group.
Whenever a user signs in to a device, you want to control features in apps, such as OneDrive or Office. In this scenario, assign your OneDrive or Office profile settings to a users group.
For example, you want to block untrusted ActiveX controls in your Office apps. You can create an Administrative Template in Intune, configure this setting, and then assign this profile to a users group.

To summarize, use user groups when you want your settings and rules to always go with the user, whatever device they use.

Exclude groups from a profile assignment

Intune device configuration profiles let you include and exclude groups from profile assignment.

As a best practice, create and assign profiles specifically for your user groups. And, create and assign different profiles specifically for your device groups. For more information on groups, see Add groups to organize users and devices.

When you assign your profiles, use the following table when including and excluding groups. A checkmark means that assignment is supported:

What you should know

Exclusion takes precedence over inclusion in the following same group type scenarios:
- Including user groups and excluding user groups
- Including device groups and excluding device group
For example, you assign a device profile to the All corporate users user group, but exclude members in the Senior Management Staff user group. Since both groups are user groups, All corporate users except the Senior Management staff get the profile.
Intune doesn't evaluate user-to-device group relationships. If you assign profiles to mixed groups, the results may not be what you want or expect.
For example, you assign a device profile to the All Users user group, but exclude an All personal devices device group. In this mixed group profile assignment, All users get the profile. The exclusion does not apply.
As a result, it's not recommended to assign profiles to mixed groups.

Note

Use caution when excluding dynamic device groups from any policy assignment. Consider the latency associated with an Azure AD dynamic device group calculation.

For example, you have a device policy that's assigned to All devices. Later, you have a requirement that new marketing devices don't receive this policy. So, you create a dynamic device group called Marketing devices based on the enrollmentProfilename property (device.enrollmentProfileName -eq 'Marketing_devices'). In the policy, you add the Marketing devices dynamic group as an excluded group.

A new marketing device enrolls in Intune for the first time, and a new Azure AD device object is created. The dynamic grouping process puts the device into the Marketing devices group with a possible delayed calculation. In parallel, the device enrolls into Intune, and starts receiving all applicable policies. The Intune policy may be deployed before the device is put in the exclusion group. This behavior results in an unwanted policy (or app) being deployed to the Marketing devices group.

As a result, it's not recommended to use dynamic device groups for exclusions in latency sensitive scenarios.

Next steps

See monitor device profiles for guidance on monitoring your profiles, and the devices running your profiles.

Programming Assignment 1: Percolation

Mac Os Mojave

Write a program to estimate the value of the percolation thresholdvia Monte Carlo simulation.

Install a Java programming environment.Install a Java programming environment on your computer by followingthese step-by-step instructions for your operating system[Mac OS X·Windows·Linux]. After following these instructions you will have stdlib.jarand algs4.jarin your Java classpath:the former contains libraries for reading data from standard input,writing data to standard output, drawing results to standard draw, generating random numbers,computing statistics, and timing programs;the latter contains all of the algorithms in the textbook.

Percolation.Given a composite systems comprised of randomly distributed insulating and metallicmaterials: what fraction of the materials need to be metallic so that the composite system is an electrical conductor? Given a porous landscape with water on the surface (or oil below),under what conditions will the water be able to drain through to the bottom (or theoil to gush through to the surface)?Scientists have defined an abstract process known as percolationto model such situations.

The model.We model a percolation system using an N-by-N grid of sites.Each site is either open or blocked.A full site is an open sitethat can be connected to an open site in the top row via a chain ofneighboring (left, right, up, down) open sites.We say the system percolates if there is a full site in the bottom row.In other words, a system percolates if we fill all open sitesconnected to the top row and that process fills some opensite on the bottom row. (For the insulating/metallic materials example, the open sites correspondto metallic materials, so that a system that percolates has a metallic path from top to bottom, with full sites conducting.For the porous substance example, the open sites correspond to empty space through which water might flow, so that a system that percolates lets water fill open sites, flowing from top to bottom.)

The problem.In a famous scientific problem, researchers are interested in thefollowing question: if sites are independently set to be open withprobability p (and therefore blocked withprobability 1 − p), what is the probability that the system percolates?When p equals 0, the system does not percolate; when p equals 1,the system percolates.The plots below show the site vacancy probability p versus the percolationprobability for 20-by-20 random grid (left) and 100-by-100 random grid (right).

When N is sufficiently large, there is a threshold value p* suchthat when p < p* a random N-by-N grid almost never percolates, and when p > p*,a random N-by-N grid almost always percolates.No mathematical solution for determining the percolation threshold p*has yet been derived.Your task is to write a computer program to estimate p*.

Percolation data type.To model a percolation system, create a data type Percolation with the following API:

Corner cases. By convention, the row and column indices i and jare integers between 0 and N − 1, where (0, 0) is the upper-left site:Throw a java.lang.IndexOutOfBoundsExceptionif any argument to open(), isOpen(), or isFull()is outside its prescribed range.The constructor should throw a java.lang.IllegalArgumentException if N ≤ 0.

Performance requirements. The constructor should take time proportional to N²; all methods shouldtake constant time plus a constant number of calls to the union-find methods union(), find(), connected(), and count().

Monte Carlo simulation.To estimate the percolation threshold, consider the following computational experiment:

Initialize all sites to be blocked.
Repeat the following until the system percolates:
- Choose a site (row i, column j) uniformly atrandom among all blocked sites.
- Open the site (row i, column j).
The fraction of sites that are opened when the system percolatesprovides an estimate of the percolation threshold.

For example, if sites are opened in a 20-by-20 grid according to the snapshots below,then our estimate of the percolation threshold is 204/400 = 0.51 because the systempercolates when the 204th site is opened.

50 open sites

100 open sites

150 open sites

204 open sites

By repeating this computation experiment T times and averaging the results,we obtain a more accurate estimate of the percolation threshold.Let x_t be the fraction of open sites in computational experiment t.The sample mean μ provides an estimate of the percolation threshold;the sample standard deviation σ measures the sharpness of the threshold.

Assuming T is sufficiently large (say, at least 30), the followingprovides a 95% confidence interval for the percolation threshold:

To perform a series of computational experiments, create a data type PercolationStatswith the following API.

The constructor should throw a java.lang.IllegalArgumentExceptionif either N ≤ 0 or T ≤ 0.

The constructor should take two argumentsN and T, and perform T independentcomputational experiments (discussed above) on an N-by-N grid. Using thisexperimental data, it should calculate the mean, standard deviation, and the 95% confidence interval for the percolation threshold. Use standard random from stdlib.jar to generate random numbers;use standard statistics from stdlib.jar to compute thesample mean and standard deviation.

Analysis of running time and memory usage. Implement the Percolation data type using the quick-find data typeQuickFindUF.javafrom algs4.jar.

Use the stopwatch data type from stdlib.jar to measure the total running time of PercolationStats.How does doubling N affect the total running time?How does doubling T affect the total running time?Give a formula (using tilde notation) of the total runningtime on your computer (in seconds) as a single function of bothN and T.
Using the 64-bit memory-cost model from lecture and Section 1.4,give the total memory usage in bytes (using tilde notation) that a Percolationobject uses to model an N-by-N percolation system.Count all memory that is used, including memory for the union-find data structure.

Now, implement the Percolation data type using the weighted quick-uniondata typeWeightedQuickUnionUF.javafrom algs4.jar.Answer the same questions in the previous two bullets.

Please wait until after Tuesday's lecture (Analysis of Algorithms) to answer these questions.
