+ The following is a description of the elements, types, and attributes that compose the Palo Alto (PAN-OS)-specific
+ tests found in Open Vulnerability and Assessment Language (OVAL). Each test is an extension
+ of the standard test element defined in the Core Definition Schema. Through extension, each test inherits a
+ set of elements and attributes that are shared amongst all OVAL tests. Each test is described in detail and
+ should provide the information necessary to understand what each element and attribute represents. This document
+ is intended for developers and assumes some familiarity with XML. A high level description of the interaction
+ between the different tests and their relationship to the Core Definition Schema is not outlined here.
+
+
+ This schema was originally developed by William Munyan at cisecurity.org. The OVAL Schema is maintained by the
+ OVAL Community. For more information, including how to get involved in the project and how to submit change
+ requests, please visit the OVAL website at http://oval.cisecurity.org.

+ The config_test is used to check the properties of the XML output from a PAN-OS XML API request to export the
+ current running configuration. This is a request to the API at "https://[PAN-OS-DEVICE]/api/?type=export&category=configuration".
+ The response to this request is an XML payload rooted with a "response" element and including device-specific information.
+ It extends the standard TestType as defined in the oval-definitions-schema and one should refer to the TestType
+ description for more information. The required object element references a config_object and the optional state
+ element specifies the data to check.
+
+
+
+ config_test
+ config_object
+ config_state
+ config_item
+
+
+
+
+
+ - the object child element of a config_test must reference a config_object
+
+
+ - the state child element of a config_test must reference a config_state
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+ The config_object element is used by a config_test to define the object to be evaluated. Each object extends the
+ standard ObjectType as defined in the oval-definitions-schema and one should refer to the ObjectType description
+ for more information. The common set element allows complex objects to be created using filters and set logic.
+ Again, please refer to the description of the set element in the oval-definitions-schema.
+
+
+ A config_object consists of an xpath entity that contains an XPATH 1.0 query to perform on the PAN-OS API response
+ XML data. The response data is assumed to consist of a <response> entity, with arbitrary (i.e., vendor-specific)
+ child nodes.
+
+
+
+
+
+
+
+
+
+
+ State referenced in filter for '' is of the wrong type.
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+ Specifies an Xpath expression describing the text node(s) or attribute(s) to look at. Any valid
+ XPath 1.0 statement is usable with one exception, at most one field may be identified in the XPath.
+ This is because the value_of element in the data section is only designed to work against a single
+ field. The only valid operator for xpath is equals since there is an infinite number of possible
+ XPaths and determinining all those that do not equal a given XPath would be impossible.
+
+
+
+
+ - operation attribute for the xpath entity of a config_object should be 'equals', note that this overrules the general operation attribute validation (i.e. follow this one)
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+ The config_state element defines the different information that can be used to evaluate the result of a specific
+ config XPath evaluation. This includes the XPath used and the value of this XPath.
+
+
+
+
+
+
+
+
+ Specifies an XPath expression describing the text node(s) or attribute(s) to look at.
+
+
+
+
+ The value_of element checks the value(s) of the text node(s) or attribute(s) found.
