This chapter is your guide to the essential configuration tasks you must complete to initially create and refine a standard security policy for a web application on the Application Security Manager. Implementing a security policy for a web application has two phases: setting up the local traffic network, and creating the application security configuration.
Define a local traffic pool.
The local traffic pool contains the web server or application server resources that host the web application that you want to protect with a security policy. You create the local traffic pool, and later associate the pool with a virtual server. See Defining a local traffic pool, for more information.
Define an application security class.
When you define an application security class (with application security enabled), the system automatically creates a corresponding web application in the Application Security Manager. See Defining an application security class, for more information.
Define a local traffic virtual server that uses the application security class as a resource.
The local traffic virtual server load balances the network resources that host the web application you are securing. The application security class is the bridge that links the security policy to the web application traffic through the virtual server. You configure the virtual server, and then associate the application security class with the virtual server. See Defining a local traffic virtual server, for more information.
Run the Deployment wizard.
Using the Deployment wizard, you create a security policy, based on one of several typical deployment scenarios. See Running the Deployment wizard, for more information.
Periodically review the security policy settings.
To ensure that the security policy is providing adequate application security, review the requests, monitoring, and statistics information on a regular basis. See Maintaining and monitoring the security policy, for more information.
This chapter describes the general tasks that you perform to configure a security policy for a web application hosted on a local traffic virtual server. The chapter does not address specific deployments or environments. For additional implementations that address the needs of a particular environment, refer to the BIG-IP® Application Security Manager: Getting Started Guide, which is available in the AskF5 Knowledge Base, support.f5.com.
Important: The tasks described in this chapter begin after you have installed the BIG-IP system, and have licensed and provisioned the Application Security Manager. If you have not yet completed these activities, refer to the BIG-IP® Systems: Getting Started Guide for additional information.
The first essential configuration task is to define a local traffic pool. The local traffic pool contains the resources that host the actual web application content that you want to protect with the security policy.
1.
On the Main tab, expand Local Traffic, and then click Pools.
The Pool List screen opens.
2.
Click the Create button.
The New Pool screen opens.
3.
In the Configuration area, in the Name box, type a name for the pool.
4.
In the Resources area, for the New Members setting, in the Address box, type the IP address for the web server or application server that hosts the web application.
5.
In the Service Port box, type the service port number (for example, type 80 for the HTTP service), or select a service name from the list.
6.
Click the Add button to add the resource to the New Members list.
7.
Click the Finished button.
The screen refreshes and the system displays the new pool in the pools list.
The second essential configuration task is to configure an application security class. An application security class is the logical bridge, or link, between the local traffic components and the application security components of the BIG-IP system. You use the application security class to specify to which incoming HTTP traffic the system applies application security before the virtual server forwards the traffic to the web application.
When you configure an application security class, the system automatically creates a default web application in the Application Security Manager. For more information on application security classes, see Chapter 3, Working with Application Security Classes. For information about web applications, see Chapter 4, Working with Web Applications.
1.
On the Main tab, expand Application Security and then click Classes.
The HTTP Class Profiles screen opens.
2.
Click the Create button.
The New HTTP Class Profile screen opens.
3.
In the General Properties area, in the Name box, type a name for the application security class.
4.
In the Configuration area, make sure that Application Security is set to Enabled, and use the default values for the other settings.
5.
Click Finished.
The system adds the class, a web application (which is unconfigured at this point), and displays the HTTP Class Profiles screen.
Note: In the Configuration utility, the application security class and the HTTP Class Profile are different labels for the same object. The difference between the two objects is that, for the application security class, the Application Security setting is enabled by default. If you disable the Application Security setting on an application security class, you effectively turn off application security for the associated web application.
The next essential configuration task is to define a virtual server on the local area network. The virtual server processes the incoming traffic, which includes applying the application security class to incoming HTTP traffic.
1.
On the Main tab, expand Local Traffic, and then click Virtual Servers.
The Virtual Server List screen opens.
2.
Click the Create button.
The New Virtual Server screen opens.
3.
In the Name box, type a name for the virtual server.
4.
For the Destination setting, select Host, and type an IP address.
5.
In the Service Port box, type 80. Alternately, you can select HTTP from the list.
6.
In the Configuration area, from the HTTP Profile list, select http.
7.
Select the SNAT Pool setting, select Auto Map.
Note: If internal traffic uses a different VLAN from external traffic, you can leave this set to None.
8.
In the Resources area, for the HTTP Class Profiles setting, from the Available list, select the application security class that you created, and move it into the Enabled list.
9.
From the Default Pool list, select the pool that is configured for application security.
10.
Click Finished.
The system updates the configuration, and the Virtual Server List screen opens, where you can see the newly created virtual server.
Note: For virtual servers that load balance resources for a web application that is protected by the Application Security Manager, you must configure an HTTP profile in addition to the application security class.
After you have completed the phase one tasks, which set up the local area network, you are ready for the phase two tasks. The phase two tasks include configuring the security policy, and monitoring the security policy.
You build a security policy for a new web application using the Deployment wizard. The Deployment wizard automates the fundamental tasks required to initially build and deploy a security policy. The Deployment wizard provides several deployment scenarios, which represent several typical environments that use application security, to guide you through the configuration process.
1.
On the Main tab, expand Application Security and click Web Applications.
The Web Application List screen opens.
2.
In the Active Security Policy column of the web application for which you want to create a security policy, click the Configure Security Policy link.
The Select Deployment Scenario screen opens.
3.
For the Deployment Scenario setting, select the appropriate option:
Create a policy automatically
Select this option if you want the system to build a security policy by examining production or QA traffic.
Create a policy manually or use templates
Select this option for rapid deployment or to create a security policy from a security policy template.
Create a policy for XML and web services manually
Select this option to protect a web service or XML application.
Create a policy using third party vulnerability assessment tool output
Select this option to build a security policy automatically based on the vulnerabilities found by a tool like WhiteHat Sentinel.
4.
Follow through the screens of the wizard.
The Description area of each wizard screen provides additional information about the screen. The online help describes each of the options on the screen.
If later you want to rerun the Deployment wizard and reconfigure a security policy, click the name of the web application on the Web Application list, then Reconfigure. If you do this, you will lose existing policies for this web application and start a new security policy from scratch.
For more information about running the Deployment wizard for a specific deployment scenario, refer to the BIG-IP® Application Security Manager: Getting Started Guide.
The Application Security Manager provides many reporting and monitoring tools, so that you can view and analyze the violations that the system detects in the traffic passing through the web application. By actively using the reporting and monitoring tools, you can be assured that your web applications are fully protected.
1.
On the Main tab, expand Application Security, and click Reporting.
The Requests screen opens.
3.
On each screen, you can use the Filter option to customize and refine the reports.
