Managing Security with Windows Firewall in Server 2022
Posted on 17th June 2023
Introduction
As the world increasingly moves online, the need for robust security solutions only becomes more pressing. For businesses, this often takes the form of a firewall, which acts as a barrier between a private network and the wider internet. In this article, we’ll be focusing on how to manage security with Windows Firewall in Server 2022.
Configuring Windows Firewall
The first step in managing security with Windows Firewall is to configure the firewall itself. This can be done through the Control Panel or the Windows Firewall with Advanced Security console. In either case, the first thing you’ll need to do is create a new rule.
When creating a new rule, you’ll need to specify the type of traffic that you want to allow or block. You can also specify the rule’s action, which can be either allow or block. You can also specify the rule’s scope, which determines which computers the rule applies to. Finally, you can specify the rule’s condition, which allows you to further customize the rule.
Managing Security Groups
Another important aspect of managing security with Windows Firewall is managing security groups. Security groups are collections of users that have been assigned a certain level of access to a network resource. There are two types of security groups: local security groups and global security groups.
Local security groups are specific to a single computer. They can be used to grant or deny access to resources on that computer. Global security groups are created in Active Directory and can be used to grant or deny access to resources on any computer in the domain. Security groups can be nested, which means that a security group can be a member of another security group.
Applying Security Policies
Once you’ve configured Windows Firewall and created the appropriate security groups, you can then apply security policies. Security policies are rules that determine which users have access to which resources. They can be applied to individual computers or to security groups. Security policies can be applied to both local and global security groups.
When applying security policies, you’ll need to specify the type of access that you want to allow or deny. You can also specify the rule’s action, which can be either allow or block. You can also specify the rule’s scope, which determines which computers the rule applies to. Finally, you can specify the rule’s condition, which allows you to further customize the rule.
Conclusion
In this article, we’ve covered the basics of managing security with Windows Firewall in Server 2022. We’ve looked at how to configure the firewall itself, how to manage security groups, and how to apply security policies. By following the steps outlined in this article, you’ll be able to effectively manage the security of your server.

If you decide to use the Windows Firewall with Advanced Security console to configure your server, you can do so by following these steps:
1. Start the Windows Firewall with Advanced Security console. You can do this by going to Start, then Administrative Tools, and then selecting Windows Firewall with Advanced Security.
2. In the console tree, expand the node for the computer on which you want to configure the Windows Firewall with Advanced Security settings.
3. In the results pane, click on the node for Inbound Rules.
4. To create a new inbound rule, click on the Action menu and then select New Rule.
5. In the New Inbound Rule Wizard, select the rule type that you want to create. For example, if you want to allow all traffic from a specific IP address, you would select the “Allow the connection if it is secure” rule type.
6. Once you have selected the rule type, click Next.
7. On the next page, you will be asked to select the protocol and port type. Select the protocol type as TCP and the specific port number that you want to allow traffic on.
8. Click Next.
9. On the next page, you will be asked to select the source of the traffic. If you want to allow traffic from a specific IP address, select the “These IP addresses” option and then click the Add button.
10. Enter the IP address that you want to allow traffic from and then click OK.
11. Click Next.
12. On the next page, you will be asked to select the action that you want the rule to take. Select the “Allow the connection” option and then click Finish.
13. Your new rule will be created and will appear in the list of inbound rules.
14. Repeat steps 4-13 for each additional inbound rule that you want to create.
15. Once you have finished creating all of your inbound rules, click on the Outbound Rules node in the results pane.
16. To create a new outbound rule, click on the Action menu and then select New Rule.
17. In the New Outbound Rule Wizard, select the rule type that you want to create. For example, if you want to allow all traffic to a specific IP address, you would select the “Allow the connection if it is secure” rule type.
18. Once you have selected the rule type, click Next.
19. On the next page, you will be asked to select the protocol and port type. Select the protocol type as TCP and the specific port number that you want to allow traffic on.
20. Click Next.
21. On the next page, you will be asked to select the destination of the traffic. If you want to allow traffic to a specific IP address, select the “These IP addresses” option and then click the Add button.
22. Enter the IP address that you want to allow traffic to and then click OK.
23. Click Next.
24. On the next page, you will be asked to select the action that you want the rule to take. Select the “Allow the connection” option and then click Finish.
25. Your new rule will be created and will appear in the list of outbound rules.
26. Repeat steps 16-25 for each additional outbound rule that you want to create.
27. Once you have finished creating all of your inbound and outbound rules, click on the Properties node in the results pane.
28. On the Properties page, select the tab for the type of traffic that you want to allow or block. For example, if you want to allow or block all traffic, select the “AllTraffic” tab.
29. On the selected tab, you will see a list of the currently allowed or blocked traffic types. To change the default setting for a traffic type, simply select the appropriate radio button.
30. Once you have finished configuring the traffic types, click OK.
By following the steps above, you can easily configure the Windows Firewall with Advanced Security to allow or block traffic on your server.
