Introduction to Checking Firewall Settings in Windows Server 2012

Firewalls play a crucial role in protecting your Windows Server 2012 from unauthorized access and security threats. By configuring firewall settings, you can control network traffic and allow or block specific programs or ports. However, it's essential to regularly check the firewall settings to ensure they are properly configured and aligned with your security requirements. In this article, we will explore different aspects of checking firewall settings in Windows Server 2012, providing you with the knowledge and steps to verify and validate your firewall configuration.

1. Checking Windows Firewall Status

Before examining the specific firewall settings, it is important to start by checking the status of the Windows Firewall to ensure it is enabled and active. Here are the steps:

• Open the Start menu and go to the Control Panel.
• Click on "System and Security" followed by "Windows Firewall."
• In the Windows Firewall window, you will find the firewall status mentioned under the "Firewall state" section. It should ideally display "On" for the firewall to be active.

If the firewall status appears as "Off," it means that the Windows Firewall is disabled. To enable it, click on the "Turn Windows Firewall on or off" link and select the appropriate firewall settings. It is recommended to keep the firewall turned on to ensure the security of your Windows Server 2012.

2. Verifying Default Firewall Profiles

Windows Server 2012 provides three different firewall profiles: Domain, Private, and Public. Each profile serves a specific purpose and applies different firewall rules based on the network location. It is crucial to verify the default firewall profiles and configure them accordingly. Follow these steps:

• Open the Start menu, go to the Control Panel, and click on "System and Security."
• Select "Windows Firewall."
• In the Windows Firewall window, click on "Advanced settings" on the left-hand side.

In the Windows Firewall with Advanced Security window, you will find the three default profiles: Domain Profile, Private Profile, and Public Profile. Check each profile to ensure they are enabled and configured according to your network requirements. You can right-click on a specific profile, select "Properties," and make the necessary changes.

3. Examining Inbound Firewall Rules

Inbound firewall rules determine the access permissions for incoming network connections. By examining inbound firewall rules, you can identify which programs or ports are allowed or blocked. Here's how to do it:

• Open the Start menu, go to the Control Panel, and select "System and Security."
• Click on "Windows Firewall."
• In the Windows Firewall window, click on "Advanced settings."

In the Windows Firewall with Advanced Security window, click on "Inbound Rules" located on the left-hand side. This will display a list of all the inbound firewall rules configured on your Windows Server 2012. Review each rule to ensure they align with your security policies and requirements.

Analyzing Inbound Rule Properties

To further verify the inbound firewall rules, you can analyze their properties. By examining the properties of a rule, you can determine its specific settings and restrictions. Follow these steps:

• In the Windows Firewall with Advanced Security window, select an inbound rule from the list.
• Right-click on the selected rule and choose "Properties."
• The properties window will display various tabs providing information about the rule, including general settings, program or port restrictions, and action (allow or block) configurations. Review each tab to understand the rule's behavior and ensure it aligns with your security policies and requirements.

4. Checking Outbound Firewall Rules

Outbound firewall rules control the network traffic leaving your Windows Server 2012. By examining outbound firewall rules, you can verify which programs or ports are allowed or blocked for outbound connections. Here's how you can do this:

• Open the Start menu, go to the Control Panel, and select "System and Security."
• Click on "Windows Firewall."
• In the Windows Firewall window, click on "Advanced settings."

In the Windows Firewall with Advanced Security window, click on "Outbound Rules" located on the left-hand side. This will display a list of all the outbound firewall rules configured on your Windows Server 2012. Review each rule to ensure they align with your security policies and requirements.

Analyzing Outbound Rule Properties

Similar to analyzing inbound rule properties, you can also examine the properties of outbound firewall rules to verify their settings and restrictions. Follow these steps:

• In the Windows Firewall with Advanced Security window, select an outbound rule from the list.
• Right-click on the selected rule and choose "Properties."
• The properties window will display various tabs providing information about the rule, including general settings, program or port restrictions, and action (allow or block) configurations. Review each tab to understand the rule's behavior and ensure it aligns with your security policies and requirements.

Exploring Advanced Firewall Settings

In addition to the basic firewall settings, Windows Server 2012 offers advanced firewall configurations that allow further control and customization. Let's delve into these advanced firewall settings:

1. Configuring Connection Security Rules

Connection security rules focus on protecting network traffic using IPsec (Internet Protocol Security). By configuring these rules, you can create secure connections between different devices, authenticate communication, and encrypt data. Here's how you can configure connection security rules:

• In the Windows Firewall with Advanced Security window, click on "Connection Security Rules" located on the left-hand side.
• The list of existing connection security rules will appear. To create a new rule, click on "New Rule" on the right-hand side and follow the wizard to configure the rule's properties.
• Review the connection security rules to ensure they reflect your security policies and requirements.

2. Managing Security Associations

Security associations are key components of IPsec, enabling secure communication between devices. Windows Server 2012 allows you to manage security associations and ensure their proper functioning. Follow these steps:

• In the Windows Firewall with Advanced Security window, click on "Security Associations" located on the left-hand side.
• The list of existing security associations will appear, displaying details such as local and remote addresses, security protocol, key exchange algorithm, and more. Review these associations to ensure their accuracy and alignment with your IPsec settings.

3. Examining Authorized Applications

Windows Server 2012 allows you to authorize specific applications for network communication. By examining the list of authorized applications, you can verify the programs that are allowed to send or receive data through the firewall. Follow these steps to access authorized applications:

• In the Windows Firewall with Advanced Security window, click on "Authorized Applications" located on the left-hand side.
• A list of authorized applications will be displayed, showing the program path, protocol, local and remote addresses, and more. Review this list to ensure only trusted and necessary applications are authorized.

Conclusion

Checking and verifying the firewall settings on your Windows Server 2012 is essential to maintain a robust security posture. By ensuring that the firewall is active, the default profiles are configured correctly, and the inbound and outbound rules align with your security policies, you can significantly reduce the risk of unauthorized access and potential security breaches. Additionally, exploring the advanced firewall settings and managing connection security rules, security associations, and authorized applications provide further control and customization options. Regularly reviewing and updating your firewall settings will help protect your server and ensure the integrity of your network infrastructure.
