TASK 3

???? Objective:

Create a user named Admin1 in contoso.com.

Admin1 must be able to back up and restore files on SRV1.

Follow the principle of least privilege.

Step-by-Step Guide

✅ Step 1: Create the User Account

Log in to a Domain Controller (e.g., DC1) with appropriate admin rights.

Open Active Directory Users and Computers (dsa.msc).

In the contoso.com domain:

Right-click the Users container or another OU where you want to create the account.

Select New > User.

Enter the following:

First name: Admin1

User logon name: Admin1

Click Next and set a password (ensure it meets the domain’s password policy).

Configure password options (e.g., User must change password at next logon, if required).

Click Finish.

✅ Step 2: Grant Backup and Restore Rights on SRV1

By default, Backup Operators have the ability to back up and restore files (without giving full admin rights).

Log in to SRV1 (the target server).

Open Computer Management (compmgmt.msc).

In the left pane, expand:

System Tools > Local Users and Groups > Groups.

Find and double-click the Backup Operators group.

Click Add.

In the Select Users, Computers, Service Accounts, or Groups window:

Type Admin1.

Click Check Names to resolve the user.

Click OK to add Admin1 to the group.

Click OK again to close the Backup Operators group properties.

✅ Step 3: Verify Access

Log in as Admin1 on SRV1 and test performing backup and restore operations using tools like Windows Server Backup.

Since Backup Operators can back up and restore data but do not have full administrative privileges, this follows the least privilege principle.

✅ Additional Notes

If you prefer using PowerShell, you can add the user to the group like this on SRV1:

Add-LocalGroupMember -Group "Backup Operators" -Member "contoso\Admin1"

One possible solution to configure SRV1 as a DNS server that can resolve names from the contoso.com domain by using DC1 and all other names by using the root hint servers is to use conditional forwarding. Conditional forwarding allows a DNS server to forward queries for a specific domain name to another DNS server, while using the normal forwarding or root hint servers for other queries. Here are the steps to configure conditional forwarding on SRV1:

On SRV1, open DNS Manager from the Administrative Tools menu or by typing dnsmgmt.msc in the Run box.

In the left pane, right-click on Conditional Forwarders and select New Conditional Forwarder.

In the New Conditional Forwarder dialog box, enter contoso.com as the DNS Domain name.

In the IP addresses of the master servers box, enter the IP address of DC1, which is the DNS server for the contoso.com domain. You can also click on Resolve to verify the name resolution of DC1.

Optionally, you can check the box Store this conditional forwarder in Active Directory, and replicate it as follows if you want to store and replicate the conditional forwarder in AD DS. You can also select the replication scope from the drop-down list.

Click OK to create the conditional forwarder.

Now, SRV1 will forward any queries for the contoso.com domain to DC1, and use the root hint servers for any other queries. You can test the name resolution by using the nslookup command on SRV1 or another computer that uses SRV1 as its DNS server. For example, you can run the following commands:

nslookup www.contoso.com

nslookup www.microsoft.com

The first command should return the IP address of www.contoso.com from DC1, and the second command should return the IP address of www.microsoft.com from a root hint server.

One possible solution to monitor the security configuration of DC1 by using Microsoft Defender for Cloud is to use the Guest Configuration feature. Guest Configuration is a service that audits settings inside Linux and Windows virtual machines (VMs) to assess their compliance with your organization’s security policies. You can use Guest Configuration to monitor the security baseline settings for Windows Server in the Microsoft Defender for Cloud portal by following these steps:

On DC1, open a web browser and go to the folder named \dc1.contoso.com\install. Download the Guest Configuration extension file (GuestConfiguration.msi) and save it to a local folder, such as C:\Temp.

Run the Guest Configuration extension file and follow the installation wizard. You can choose to install the extension for all users or only for the current user. For more information on how to install the Guest Configuration extension, see Install the Guest Configuration extension.

After the installation is complete, sign in to the Microsoft Defender for Cloud portal (2).

In the left pane, select Security Center and then Recommendations.

In the recommendations list, find and select Vulnerabilities in security configuration on your Windows machines should be remediated (powered by Guest Configuration).

In the Remediate Security Configurations page, you can see the compliance status of your Windows VMs, including DC1, based on the Azure Compute Benchmark. The Azure Compute Benchmark is a set of rules that define the desired configuration state of your VMs. You can also see the number of failed, passed, and skipped rules for each VM. For more information on the Azure Compute Benchmark, see Microsoft cloud security benchmark: Azure compute benchmark is now available.

To view the details of the security configuration of DC1, click on the VM name and then select View details. You can see the list of rules that apply to DC1 and their compliance status. You can also see the severity, description, and remediation steps for each rule. For example, you can see if DC1 has the latest security updates installed, if the firewall is enabled, if the password policy is enforced, and so on.

To monitor the security configuration of DC1 over time, you can use the Compliance over time chart, which shows the trend of compliance status for DC1 in the past 30 days. You can also use the Compliance breakdown chart, which shows the distribution of compliance status for DC1 by rule severity.

By using Guest Configuration, you can monitor the security configuration of DC1 by using Microsoft Defender for Cloud and ensure that it meets your organization’s security standards. You can also use Guest Configuration to monitor the security configuration of other Windows and Linux VMs in your Azure environment.

To create an AD DS site named Site2 that is associated to an IP address range of 192.168.2.0 to 192.168.2.255, you can follow these steps:

On a domain controller or a computer that has the Remote Server Administration Tools (RSAT) installed, open Active Directory Sites and Services from the Administrative Tools menu or by typing dssite.msc in the Run box.

In the left pane, right-click on Sites and select New Site.

In the New Object - Site dialog box, enter Site2 as the Name of the new site. Select a site link to associate the new site with, such as DEFAULTIPSITELINK, and click OK. You can also create a new site link if you want to customize the replication frequency and schedule between the sites. For more information on how to create a site link, see Create a Site Link.

In the left pane, right-click on Subnets and select New Subnet.

In the New Object - Subnet dialog box, enter 192.168.2.0/24 as the Prefix of the subnet. This notation represents the IP address range of 192.168.2.0 to 192.168.2.255 with a subnet mask of 255.255.255.0. Select Site2 as the Site object to associate the subnet with, and click OK.

Wait for the changes to replicate to other domain controllers. You can verify the site and subnet creation by checking the Sites and Subnets containers in Active Directory Sites and Services.

Now, you have created an AD DS site named Site2 that is associated to an IP address range of 192.168.2.0 to 192.168.2.255. You can add domain controllers to the new site and configure the site links and site link bridges to optimize the replication topology.

To create a GPO named GPO1 that only applies to a group named MemberServers, you can follow these steps:

On a domain controller or a computer that has the Remote Server Administration Tools (RSAT) installed, open Group Policy Management from the Administrative Tools menu or by typing gpmc.msc in the Run box.

In the left pane, expand your domain and right-click on Group Policy Objects. Select New to create a new GPO.

In the New GPO dialog box, enter GPO1 as the Name of the new GPO and click OK. You can also optionally select a source GPO to copy the settings from.

Right-click on the new GPO and select Edit to open the Group Policy Management Editor. Here, you can configure the settings that you want to apply to the group under the Computer Configuration and User Configuration nodes. For more information on how to edit a GPO, see Edit a Group Policy Object.

Close the Group Policy Management Editor and return to the Group Policy Management console. Right-click on the new GPO and select Scope. Here, you can specify the scope of management for the GPO, such as the links, security filtering, and WMI filtering.

Under the Security Filtering section, click on Authenticated Users and then click on Remove. This will remove the default permission granted to all authenticated users and computers to apply the GPO.

Click on Add and then type the name of the group that you want to apply the GPO to, such as MemberServers. Click OK to add the group to the security filter. You can also click on Advanced to browse the list of groups available in the domain.

Optionally, you can also configure the WMI Filtering section to further filter the GPO based on the Windows Management Instrumentation (WMI) queries. For more information on how to use WMI filtering, see Filter the scope of a GPO by using WMI filters.

To link the GPO to an organizational unit (OU) or a domain, right-click on the OU or the domain in the left pane and select Link an Existing GPO. Select the GPO that you created, such as GPO1, and click OK. You can also change the order of preference by using the Move Up and Move Down buttons.

Wait for the changes to replicate to other domain controllers. You can also force the update of the GPO by using the gpupdate /force command on the domain controller or the client computers. For more information on how to update a GPO, see Update a Group Policy Object.

Now, you have created a GPO named GPO1 that only applies to a group named MemberServers. You can verify the GPO application by using the gpresult /r command on a member server and checking the Applied Group Policy Objects entry. You can also use the Group Policy Results wizard in the Group Policy Management console to generate a report of the GPO application for a specific computer or user. For more information on how to use the Group Policy Results wizard, see Use the Group Policy Results Wizard.

To deploy a new primary DNS zone named fabrikam.com to DC1 and sign the zone, you can follow these steps:

Step 1: Create the Primary DNS Zone Use the Add-DnsServerPrimaryZone PowerShell command to create the primary zone:

Add-DnsServerPrimaryZone -Name "fabrikam.com" -ZoneFile "fabrikam.com.dns" -DynamicUpdate Secure

This command creates a primary zone for fabrikam.com with a DNS file named fabrikam.com.dns and allows secure dynamic updates.

Step 2: Sign the Zone To sign the zone, you can use the DNS Manager or Windows PowerShell. Here’s how to sign the zone using PowerShell:

Add-DnsServerSigningKey -ZoneName "fabrikam.com" -Type KeySigningKey -CryptoAlgorithm RsaSha256

Set-DnsServerDnsSecZoneSetting -ZoneName "fabrikam.com" -DenialOfExistence NSEC3 -NSEC3Parameters 1,0,10,""

These commands add a signing key to the zone and set DNSSEC settings with NSEC3 parameters.

Step 3: Publish the Signed Zone After signing the zone, ensure that it is published and available for DNS queries. You can verify the zone signing status using the following command:

Get-DnsServerZone -Name "fabrikam.com"

Note: Ensure that you have the appropriate permissions to perform these actions on DC1 and that the DNS Server role is installed and properly configured. Also, replace "fabrikam.com.dns" with the actual path to your DNS file if it’s different12.

By following these steps, you should be able to deploy and sign the new primary DNS zone fabrikam.com on DC1.

The period . at the end of the command tells Docker to use the Dockerfile in the current directory.

Step 4: Verify the Image Creation After the build process completes, verify that the image app1 has been created successfully by listing all images:

docker images

You should see app1 in the list of images.

Step 5: Use the Image Now, you can use the image app1 to run containers or push it to a container registry if needed.

By following these steps, you’ll have created a Docker container image named app1 using the Dockerfile located in C:\app on SRV11. Ensure that Docker is installed on SRV1 and that you have the necessary permissions to execute these commands.

One possible solution to prevent domain users from saving executable files in a share named \SRVl\Data is to use file screening on the file server. File screening allows you to block certain files from being saved based on their file name extension. Here are the steps to configure file screening:

On the file server, open File Server Resource Manager from the Administrative Tools menu.

In the left pane, expand File Screening Management and click on File Groups.

Right-click on File Groups and select Create File Group.

In the File Group Properties dialog box, enter a name for the file group, such as Executable Files.

In the Files to include box, enter the file name extensions that you want to block, such as .exe, .bat, .cmd, .com, .msi, .scr. You can use wildcards to specify multiple extensions, such as *.exe.

Click OK to create the file group.

In the left pane, click on File Screen Templates.

Right-click on File Screen Templates and select Create File Screen Template.

In the File Screen Template Properties dialog box, enter a name for the template, such as Block Executable Files.

On the Settings tab, select the option Active screening: Do not allow users to save unauthorized files.

On the File Groups tab, check the box next to the file group that you created, such as Executable Files.

On the Notification tab, you can configure how to notify users and administrators when a file screening event occurs, such as sending an email, logging an event, or running a command or script. You can also customize the message that users see when they try to save a blocked file.

Click OK to create the file screen template.

In the left pane, click on File Screens.

Right-click on File Screens and select Create File Screen.

In the Create File Screen dialog box, enter the path of the folder that you want to apply the file screening to, such as \SRVl\Data.

Select the option Derive properties from this file screen template (recommended) and choose the template that you created, such as Block Executable Files.

Click Create to create the file screen.

Now, domain users will not be able to save executable files in the share named \SRVl\Data. They will be able to save other files to the share.
