Windows Server 2. R2 Firewall Security Todays security model is all about layers. To manually disable Windows Firewall on XP SP2 machines, open Windows Firewall in Control Panel and select the Off option on the General tab Scenario 2. Windows Azure Pack configures the proper firewall ports for you, but what if you need to customize or you notice suspicious trafficIf your network suffers a breach, security layers can at least limit the scope of the attack or slow down the hacker. In my experience, Windows Server 2. R2 and Windows Server 2. Windows Server in which you can successfully keep your firewall enabled and still have the server work in a production environment. The Microsoft Management Console MMC Firewall with Advanced Security snap in is key to this capability. Firewall Profiles There are three different Windows Firewall profiles that can be configured with a Server 2. R2 firewall. Only one of these profiles can be active at a time. Domain profileThis profile is active when the server is connected to an Active Directory AD domain via an internal network. This is the profile thats typically active, because most servers are members of an AD domain. Private profileThis profile is active when the server is a member of a workgroup. Microsoft recommends more restrictive firewall settings for this profile than for the domain profile. Public profileThis profile is active when the server is connected to an AD domain via a public network. Microsoft recommends the most restrictive settings for this profile. When you start the Firewall with Advanced Security snap in, you can view which firewall profile is active. Although Microsoft recommends that you can have different security settings based on the firewall profile, I typically configure the firewall as if a perimeter firewall doesnt exist. With this approach, if any ports are accidentally opened on perimeter firewalls, Server 2. Windows Firewall will block the traffic. Just as with previous versions of Windows Firewall, all inbound connections are blocked and all outbound connections from the server are allowed by default in Server 2. R2 as long as theres no existing Deny rule. With these settings, my organizations firewall configuration leans toward a public profile environment. When we create a rule, we make it active for all three profiles. By using a firewall configuration thats consistent across all three domain profiles, we dont have to worry about exposing any unwanted ports in case the Windows Firewall profile changes. IPsec and Domain Isolation You can implement domain isolation by using Windows Firewalls IPsec feature. Domain isolation prevents the communication of a non domain computer from connecting to a computer thats a domain member. When communication is established between two domain members, you can configure the firewall to encrypt all traffic between the two computers with IPsec. This configuration can be useful in an environment in which you have guests on the same network but you want to prevent them from accessing computers that are part of a domain. It can be used as an alternative or in addition to Virtual LANs VLANs. For more information about domain isolation with IPsec tunnels, see the Microsoft Tech. Net article Domain Isolation with Microsoft Windows Explained. Leave the Firewall Enabled I suggest leaving the firewall enabled when Server 2. If you want to minimize connections from Windows to Microsoft services, or configure particular privacy settings, this article covers the settings that you could. R2 is first installed. Most applications are now smart enough to automatically open the necessary port on the firewall when theyre installed, which eliminates the need to manually open inbound ports on the server. One of the main reasons to have the firewall up during installation is that it protects the OS before you have the chance to apply the latest updates. The firewall is well integrated with Server Managers roles and features. When a role or feature is added on the server, the firewall automatically opens the necessary inbound ports. SQL Server uses the default port of TCP 1. Therefore, you must manually create an inbound rule that allows TCP port 1. SQL Server. Alternatively, you can change the default. Creating Inbound Rules If you leave the firewall enabled, youll probably need to manually create an inbound firewall rule at some point. Fortunately, there are quite a few rules that are created but disabled by default for many popular Windows applications. Before creating a rule, check to see whether a rule was already created that will allow the desired inbound traffic to pass. If you find an existing rule, you can simply enable the rule and possibly change the default scope. If you dont find an existing rule, you can always create one from scratch. Select Administrative Tools from the Start menu, then select Windows Firewall with Advanced Security to start the Firewall with Advanced Security snap in. For illustration purposes, Ill explain how to create a rule to allow inbound SQL Server traffic on TCP port 1. Microsoft Office Share. Point Server front end server. Right click Inbound Rules and select New Rule. As Figure 1 shows, you can select Program, Port, Predefined, or Custom for the rule type. I typically select Custom, because this option prompts you to enter a scope for the rule. Click Next to continue. In the next dialog box, which Figure 2 shows, you can specify a program or services that the rule will match. In my example, I selected All programs so that traffic will be controlled by the port number. As Figure 3 shows, I then selected TCP for the protocol type, and I selected Specific Ports from the Local port drop down menu and specified port 1. SQL Server. Because remote ports are dynamic, I selected All Ports. In the Scope dialog box, which Figure 4 shows, I specified the local IP address of 1. IP address of 1. 92. IP address of my organizations Share. Download Budget For Youth Football Program. Point front end server. I strongly recommend specifying a scope with every rule, in case the server is accidentally exposed to unwanted subnets. In the Action dialog box, which Figure 5 shows, I selected Allow the connection because I want to allow inbound traffic to pass for SQL Server. Alternatively, you can allow traffic to pass only if its encrypted and secured with IPsec, or you can block the connection. Next, you need to specify the profiles for which the rule will apply. As Figure 6 shows, I selected all the profiles which is a best practice. Finally, use a descriptive name for the rule, specifying the allowed service, scope, and ports, as Figure 7 shows. Using a descriptive name makes it easier to identify what a rule does. Click Finish to create the new inbound rule. Creating Outbound Rules By default, all inbound traffic is blocked and all outbound traffic is allowed on all three firewall profiles i. If you use the default settings, you dont need to open any outbound ports. Alternatively, you can block outbound trafficbut then you must open up the necessary outbound ports. Creating outbound rules is similar to creating inbound rules, except the traffic flow is reversed. You can use the Firewall with Advanced Security snap into block outbound traffic on specific ports if the server becomes infected with a virus and attempts to attack other computers on specific ports. Managing Firewall Configuration In addition to the Firewall with Advanced Security snap in, you can use Netsh commands to create firewall rules. For more information about using Netsh to configure Windows Firewall, see the article How to use the netsh advfirewall firewall context instead of the netsh firewall context to control Windows Firewall behavior in Windows Server 2.
