Table of Contents   |   << Previous Chapter   |   Next Chapter >>

This chapter is your guide to the essential configuration tasks you must complete to initially create a 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.
Note: If you have a standalone Application Security Manager system, you can optionally perform the phase one configuration tasks as part of creating a security policy using the Deployment wizard.
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 security policy 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 details.
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.
Note: If you have a standalone Application Security Manager system, you can optionally create a pool as part of creating a security policy using the Deployment wizard.
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 field, type a name for the pool.
4.
In the Resources area, for the New Members setting, in the Address field, type the IP address for the web server or application server that hosts the web application.
5.
In the Service Port field, 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 security policy in the Application Security Manager. For more information on application security classes, see Chapter 3, Working with Application Security Classes.
Note: If you have a standalone Application Security Manager system, you can optionally create an application security class as part of creating a security policy using the Deployment wizard.
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 field, 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 security policy (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 is that, for the application security class, the Application Security setting is enabled by default. If you disable the Application Security setting, you effectively turn off application security for the associated security policy.
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.
Note: If you have a standalone Application Security Manager system, you can optionally create a virtual server as part of creating a security policy using the Deployment wizard.
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 field, type a name for the virtual server.
4.
For the Destination setting, select Host, and type an IP address.
5.
In the Service Port field, 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 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 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 Security Policies.
The Active Policies screen opens.
2.
In the Security Policy Name column of the 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, IBM AppScan, Cenzic Hailstorm, or QualysGuard.
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.
For more information about running the Deployment wizard for a specific deployment scenario, refer to the BIG-IP® Application Security Manager: Getting Started Guide.
If you have a standalone system, you can skip the procedures for defining a local traffic pool and configuring a virtual server on a local area network, as described in sections Defining a local traffic pool and Defining a local traffic virtual server. You can perform those same tasks through the LTM deployment wizard for standalone systems.
1.
On the Main tab, expand Application Security and click Security Policies.
The Active Policies screen opens.
1.
Click Create.
The LTM Wizard opens.
2.
For Local Traffic Deployment Scenario, select the appropriate option:
Existing Virtual Server
Select this option if you already configured an existing virtual server.
New Virtual Server
Select this if you want to create a new virtual server.
3.
Click Next.
4.
For Deployment Type, select the appropriate option:
HTTP
If you select HTTP, you are only required to specify one existing virtual server.
HTTPS
If you select HTTPS, you are only required to specify one existing virtual server.
HTTP and HTTPS
If you select HTTP and HTTPS, you are required to specify two existing virtual servers. Both servers are associated with the security policy.
6.
For HTTP(S) Virtual Server Destination, type in the destination address of your virtual server.
7.
For HTTPS Pool Member, type the IP address for the web server or application server that hosts the web application/
8.
In the Service Port field, type the service port number (for example, type 80 for the HTTP service), or select a service name from the list
9.
Optionally, you can select an SSL profile for either your client or server.
An SSL Profile for the client is used between the BIG-IP and the user browser, while an SSL Profile for the server is used between the BIG-IP and the server.
10.
Click Next.
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.
