A definition is the key structure in OVAL. It is analogous to the logical sentence or proposition: if a computer's state matches the configuration parameters laid out in the criteria, then that computer exhibits the state described. The DefinitionType contains a section for various metadata related elements that describe the definition. This includes a description, version, affected system types, and reference information. The notes section of a definition should be used to hold information that might be helpful to someone examining the technical aspects of the definition. For example, why certain tests have been included in the criteria, or maybe a link to where further information can be found. The DefinitionType also (unless the definition is deprecated) contains a criteria child element that joins individual tests together with a logical operator to specify the specific computer state being described.</xsd:documentation> <xsd:documentation>The required id attribute is the OVAL-ID of the Definition. The form of an OVAL-ID must follow the specific format described by the oval:DefinitionIDPattern. The required version attribute holds the current version of the definition. Versions are integers, starting at 1 and incrementing every time a definition is modified. The required class attribute indicates the specific class to which the definition belongs. The class gives a hint to a user so they can know what the definition writer is trying to say. See the definition of oval-def:ClassEnumeration for more information about the different valid classes. The optional deprecated attribute signifies that an id is no longer to be used or referenced but the information has been kept around for historic purposes.</xsd:documentation> <xsd:documentation>When the deprecated attribute is set to true, the definition is considered to be deprecated. The criteria child element of a deprecated definition is optional. If a deprecated definition does not contain a criteria child element, the definition must evaluate to "not evaluated". If a deprecated definition contains a criteria child element, an interpreter should evaluate the definition as if it were not deprecated, but an interpreter may evaluate the definition to "not evaluated".</xsd:documentation> <xsd:appinfo> <sch:pattern id="oval-def_required_criteria"> <sch:rule context="oval-def:oval_definitions/oval-def:definitions/oval-def:definition[(@deprecated='false' or @deprecated='0') or not(@deprecated)]"> <sch:assert test="oval-def:criteria">A valid OVAL Definition must contain a criteria unless the definition is a deprecated definition.</sch:assert> </sch:rule> </sch:pattern> </xsd:appinfo> </xsd:annotation> <xsd:sequence> <xsd:element ref="ds:Signature" minOccurs="0" maxOccurs="1"/> <xsd:element name="metadata" type="oval-def:MetadataType"> <xsd:unique name="UniqueAffectedFamily"> <xsd:annotation> <xsd:documentation>Each affected element must have a unique family attribute value.</xsd:documentation> </xsd:annotation> <xsd:selector xpath="oval-def:affected"/> <xsd:field xpath="@family"/> </xsd:unique> </xsd:element> <!-- JovalCM changed to ref oval:notes --> <xsd:element ref="oval:notes" minOccurs="0" maxOccurs="1"/> <xsd:element name="criteria" type="oval-def:CriteriaType" minOccurs="0" maxOccurs="1"/> </xsd:sequence> <xsd:attribute name="id" type="oval:DefinitionIDPattern" use="required"/> <xsd:attribute name="version" type="xsd:nonNegativeInteger" use="required"/> <xsd:attribute name="class" type="oval:ClassEnumeration" use="required"/> <xsd:attribute name="deprecated" type="xsd:boolean" use="optional" default="false"/> </xsd:complexType> <xsd:complexType name="MetadataType"> <xsd:annotation> <xsd:documentation>The MetadataType complex type contains all the metadata available to an OVAL Definition.

The affected metadata item contains information about the system(s) for which the definition has been written. Remember that this is just metadata and not part of the criteria. Please refer to the AffectedType description for more information. The required description element contains a textual description of the configuration state being addressed by the OVAL Definition. In the case of a definition from the vulnerability class, the reference is usually the Common Vulnerability and Exposures (CVE) Identifier, and this description field corresponds with the CVE description.</xsd:documentation> <xsd:documentation>Additional metadata is also allowed although it is not part of the official OVAL Schema.

For instance, to help a reporting tool only use Windows definitions, or to preselect only Red Hat definitions to be evaluated. Note, the inclusion of a particular platform or product does not mean the definition is physically checking for the existence of the platform or product. For the actual test to be performed, the correct test must still be included in the definition's criteria section.</xsd:documentation> <xsd:documentation>The AffectedType complex type details the specific system, application, subsystem, library, etc. for which a definition has been written. If a definition is not tied to a specific product, then this element should not be included. The absence of the platform or product element can be thought of as definition applying to all platforms or products. The inclusion of a particular platform or product does not mean the definition is physically checking for the existence of the platform or product. For the actual test to be performed, the correct test must still be included in the definition's criteria section. To increase the utility of this element, care should be taken when assigning and using strings for product names. The schema places no restrictions on the values that can be assigned, potentially leading to many different representations of the same value. For example, 'Internet Explorer' and 'IE' might be used to refer to the same product. The current convention is to fully spell out all terms, and avoid the use of abbreviations at all costs.</xsd:documentation> <xsd:documentation>Please note that the AffectedType will change in future versions of OVAL in order to support the Common Platform Enumeration (CPE).</xsd:documentation> </xsd:annotation> <xsd:sequence> <xsd:element name="platform" type="xsd:string" minOccurs="0" maxOccurs="unbounded"/> <xsd:element name="product" type="xsd:string" minOccurs="0" maxOccurs="unbounded"/> </xsd:sequence> <xsd:attribute name="family" type="oval:FamilyEnumeration" use="required"/> </xsd:complexType> <xsd:complexType name="ReferenceType"> <xsd:annotation> <xsd:documentation>The ReferenceType complex type links the OVAL Definition to a definitive external reference.

The default value for this attribute is 'at_least_one_exists' indicating that by default the test may evaluate to true if at least one item defined by the OVAL Object exists on the system. For example, if a value of 'all_exist' is given, every item defined by the OVAL Object must exist on the system for the test to evaluate to true. If the OVAL Object uses a variable reference, then every value of that variable must exist. Note that a pattern match defines a unique set of matching items found on a system. So when check_existence = 'all_exist' and a regex matches anything on a system the test will evaluate to true (since all matching objects on the system were found on the system). When check_existence = 'all_exist' and a regex does not match anything on a system the test will evaluate to false.</xsd:documentation> <xsd:documentation>The required check attribute specifies how many items in the set defined by the OVAL Object (ignoring items with a status of Does Not Exist) must satisfy the state requirements. For example, should the test check that all matching files have a specified version or that at least one file has the specified version? The valid check values are explained in the description of the CheckEnumeration simple type. Note that if the test does not contain any references to OVAL States, then the check attribute has no meaning and can be ignored during evaluation.</xsd:documentation> <xsd:documentation>An OVAL Test evaluates to true if both the check_existence and check attributes are satisfied during evaluation. The evaluation result for a test is determined by first evaluating the check_existence attribute. If the result of evaluating the check_existence attribute is true then the check attribute is evaluated. An interpreter may choose to always evaluate both the check_existence and the check attributes, but once the check_existence attribute evaluation has resulted in false the overall test result after evaluating the check attribute will not be affected.</xsd:documentation> <xsd:documentation>The optional state_operator attribute provides the logical operator that combines the evaluation results from each referenced state on a per item basis. Each matching item is compared to each referenced state. The result of comparing each state to a single item is combined based on the specified state_operator value to determine one result for each item. Finally, the results for each item are combined based on the specified check value. Note that if the test does not contain any references to OVAL States, then the state_operator attribute has no meaning and can be ignored during evaluation. Referencing multiple states in one test allows ranges of possible values to be expressed. For example, one state can check that a value greater than 8 is found and another state can check that a value of less than 16 is found. In this example the referenced states are combined with a state_operator = 'AND' indicating that the conditions of all referenced states must be satisfied and that the value must be between 8 AND 16.

It defaults to 'false' meaning backslash should be interpreted as an escape character (backslash is allowed to be used as an escape character). If the glob_noescape attribute would be set to 'true' it instructs the glob_to_regex function to interpret the backslash ('\') character as a literal, rather than as an escape character (backslash is *not* allowed to be used as an escape character). For example given the input glob pattern would be '\*' then the resulting Perl 5's regular expression would be '^\\.*$' in the default (glob_noescape=false) case (here '\' would be interpreted as an escape character), and would produce '^\.*$' in glob_noescape=true case (since here '\' would be interpreted as an literal). Similarly the output for '\?' glob pattern would be '^\\.$' (default, glob_noescape=false case), and '^\.$' for glob_noescape=true case. The glob_to_regex function will fail to perform the conversion and return an error when the provided string argument (to represent glob pattern) does not represent a syntactically correct glob pattern. For example given the 'a*b?[' as the argument to be converted, glob_to_regex would return an error since there's missing the corresponding closing bracket in the provided glob pattern argument. Also, it is necessary to mention that the glob_to_regex function respects the default behaviour for the input glob pattern and output Perl 5's regular expression spaces. Namely this means that: - glob_to_regex will rule out matches having special meaning, such as: * '.' as a representation of the current working directory, * '..' as a representation of the parent directory of the current working directory, - glob_to_regex will rule out matches starting with '.' (e.g. dotfiles) unless the provided glob pattern itself starts with the '.' character too, - glob_to_regex will not perform case-sensitivity transformation (alphabetical characters will be copied from input glob pattern space to output Perl 5's regular expression pattern space intact). It is kept as a responsibility of the OVAL content author to provide input glob pattern argument in such case so the resulting Perl 5's regular expression pattern will match the expected pathname entries according to the case of preference, - glob_to_regex will not perform any possible brace expansion. Therefore glob patterns like '{pat,pat,pat}' would be converted into Perl 5's regular expression syntax in original un-expanded form (kept for any potential subsequent expansion to be performed by Perl 5's regular expression engine in the moment of the use of that resulting regular expression), - glob_to_regex will not perform tilde ('~') character substitution to user name home directory pathname. The tilde ('~') character will be passed to Perl 5's regular expression engine intact. If user name home directory pathname glob pattern behaviour is expected, the pathname of the user name home directory needs to be specified in the original glob pattern already, - glob_to_regex function will not perform any custom changes wrt to the ordering of items (perform any additional sorting of set of pathnames represented by the provided glob pattern argument). </xsd:documentation> <xsd:appinfo> <sch:pattern id="oval-def_globtoregexfunctionrules"> <sch:rule context="oval-def:glob_to_regex/oval-def:literal_component"> <sch:assert test="not(@datatype) or @datatype='string'">A literal_component used by the glob_to_regex function must have a datatype of string.</sch:assert> </sch:rule> <sch:rule context="oval-def:glob_to_regex/oval-def:variable_component"> <sch:let name="var_ref" value="@var_ref"/> <sch:assert test="ancestor::oval-def:oval_definitions/oval-def:variables/*[@id=$var_ref]/@datatype = 'string'">The variable referenced by the glob_to_regex function must have a datatype of string.</sch:assert> </sch:rule> </sch:pattern> </xsd:appinfo> </xsd:annotation> <xsd:sequence> <xsd:group ref="oval-def:ComponentGroup"/> </xsd:sequence> <xsd:attribute name="glob_noescape" type="xsd:boolean" use="optional" default="false"/> </xsd:complexType> <!-- =============================================================================== --> <!-- ================================= SIGNATURE ================================= --> <!-- =============================================================================== --> <!-- The signature element is defined by the xmldsig schema.

For example, with the statement 'is 123 less than 98'. If the data is treated as integers the answer is no, but if the data is treated as strings, then the answer is yes. Specifying a datatype defines how the less than operation should be performed. Another way of thinking of things is that the datatype attribute specifies how the data should be cast before performing the operation (note that the default datatype is 'string'). In the previous example, if the datatype is set to int, then '123' and '98' should be cast as integers. Another example is applying the 'equals' operation to '1.0.0.0' and '1.0'. With datatype 'string' they are not equal, with datatype 'version' they are. Note that there are certain cases where a cast from one datatype to another is not possible. If a cast cannot be made, (trying to cast 'abc' to an integer) then an error should be reported. For example, if the datatype is set to 'integer' and the value is the empty string.

If the element is part of an object declaration, then the object element referencing it is considered to not exist. If the element is part of a state declaration, then the state element referencing it will evaluate to error.</xsd:documentation> </xsd:annotation> </xsd:attribute> <xsd:attribute name="var_check" type="oval:CheckEnumeration" use="optional"> <xsd:annotation> <xsd:documentation>The optional var_check attribute specifies how data collection or state evaluation should proceed when an element uses a var_ref attribute, and the associated variable defines more than one value. For example, if an object entity 'filename' with an operation of 'not equal' references a variable that returns five different values, and the var_check attribute has a value of 'all', then an actual file on the system matches only if the actual filename does not equal any of the variable values. As another example, if a state entity 'size' with an operation of 'less than' references a variable that has five different integer values, and the var_check attribute has a value of 'all', then the 'size' state entity evaluates to true only if the corresponding 'size' item entity is less than each of the five integers defined by the variable. If a variable does not have any value value when referenced by an OVAL Object the object should be considered to not exist. If a variable does not have any value when referenced by an OVAL State an error should be reported during OVAL analysis. When an OVAL State uses a var_ref, if both the state entity and a corresponding item entity are collections of values, the var_check is applied to each value of the item entity individually, and all must evaluate to true for the state entity to evaluate to true. In this condition, there is no value of var_check which enables an element-wise comparison, and so there is no way to determine whether the two entities are truly 'equal' in that sense. If var_ref is present but var_check is not, the element should be processed as if var_check has the value "all".</xsd:documentation> </xsd:annotation> </xsd:attribute> </xsd:attributeGroup> <xsd:complexType name="EntitySimpleBaseType" abstract="true"> <xsd:annotation> <xsd:documentation>The EntitySimpleBaseType complex type is an abstract type that defines the default attributes associated with every simple entity.
