The following is a description of the elements, types, and attributes that compose the Cisco ASA specific system characteristic items found in Open Vulnerability and Assessment Language (OVAL). Each item is an extension of the standard item element defined in the Core System Characteristic Schema. Through extension, each item inherits a set of elements and attributes that are shared amongst all OVAL Items. Each item 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 System Characteristic Schema is not outlined here.
The OVAL Schema is maintained by The MITRE Corporation and developed by the public 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.mitre.org.
Thanks to Omar Santos and Panos Kampanakis of Cisco for providing these tests.
Stores command that are part of a asa configuration section. For example all configuration lines under an interface. It should not store configurations for configs that already have a separate item. For example OSPF has a router item and should not also be stored in a acl_item.

For example an http inspect policy-map could have 'match body regex regexnameX' and the action be 'drop'. Then this element would be 'body regex regexnameX_-_drop'. used_in oval-sc:EntityItemStringType 0 1 Element with the name of policy-map that includes the policy-map('policy-map type inspect' in this case) or the serice-policy that applies the policy-map (non 'type inspect' in this case). For example, the former could be when a http inspection policy-map policymapnameX is used in a policy-map policymapnameY as its 'inspect http policymapnameX' command. The latter could be when policymapnameY is applied globally with 'service-policy policymapnameY global'. There is no chance where a policy-map can be used in both a policy-map and a service policy at the same time.
