Application Security Manager™ can protect AJAX applications including those that use JSON or XML for data transfer between the client and the server. If the AJAX application uses XML for data transfer, the security policy requires that an XML profile be associated with a URL or parameter. If the AJAX application uses JSON for data transfer, the security policy requires that a JSON profile be associated with a URL or parameter. If the AJAX application uses HTTP for data transfer, no profile is needed.
You can also set up AJAX blocking response behavior for applications so that if a violation occurs during AJAX-generated traffic, the system displays a message or redirects the application user to another location.
|Fundamental||Creates a security policy enforcing HTTP protocol compliance, evasion techniques, explicit file types (including length checks), explicit parameters in selective mode at the global level, attack signatures, the violation Request Length Exceeds Defined Buffer Size, host names, header lengths, cookie lengths, and the violation Failed to Convert Character.|
|Enhanced||Creates a security policy with all the elements of the Fundamental policy type; also checks for explicit URLs in selective mode plus meta characters, Explicit parameter length checks in selective mode at the global level, methods, explicit cookies, and content profiles.|
|Comprehensive||Creates a security policy with all the elements of the Enhanced policy type; also checks for explicit URLs and meta characters, explicit parameters and lengths at the URL level, parameter meta characters, and dynamic parameters.|
|Fast||Use if your application supports a small number of requests from a small number of sessions; for example, useful for web sites with less traffic. However, choosing this option may present a greater chance of adding false entities to the security policy.|
|Medium||Use if your application supports a medium number of requests, or if you are not sure about the amount of traffic on the application web site. This is the default setting.|
|Slow||Use if your application supports a large number of requests from many sessions; for example, useful for web sites with lots of traffic. This option creates the most accurate security policy, but takes Policy Builder longer to collect the statistics.|
|All||Specifies that the policy trusts all IP addresses. For example, if the traffic is in a corporate lab or preproduction environment where all of the traffic is trusted, the policy is created faster when you select this option.|
|Address List||Specifies networks to consider safe. Fill in the IP Address and Netmask fields, then click Add. This option is typically used in a production environment where traffic could come from untrusted sources. The IP Address can be either an IPv4 or an IPv6 address.|
|Enabled||The system is configured to automatically build a security policy, and the Policy Builder is processing traffic.|
|Disabled||The system is not processing traffic. Check the automatic policy building configuration. If you did not associate a virtual server, you need to do that to process traffic.|
|Detecting Language||The system is still configuring the language after analyzing responses to identify the language of the web application. The Policy Builder is enabled, but it cannot add elements to the security policy until the language is set.|
The Real Traffic Policy Builder® creates a security policy that can protect applications that use AJAX with JSON or XML for data transfer between the client and the server. The system examines the traffic and creates an appropriate profile. If the application uses XML, the security policy includes one or more XML profiles associated with URLs or parameters. If the application uses JSON, the security policy includes one or more JSON profiles associated with URLs or parameters.
