Win_Memory_Page_Region_Object 2.1 01/22/2014 The following specifies the fields and types that compose this defined CybOX Object type. Each defined object is an extension of the abstract ObjectPropertiesType, defined in CybOX Common. For more information on this extension mechanism, please see the CybOX Specification.

The Windows_Memory_Page_Region object is intended represent a single Windows memory page region. The WindowsMemoryPageRegionObjectType type is intended to characterize Windows memory page regions. The Type field specifies the type of pages in the memory page region. The Allocation_Base_Address field specifies the base address of the memory page region when the region was first allocated. The Allocation_Protect field specifies the memory protection option for the memory page region when the region was initially allocated. The State field specifies the state of the memory pages in the region. The Protect field specifies the access protection of the memory pages in the region. MemoryPageProtectionType specifies memory protection constant types, via a union of the MemoryPageProtectionEnum type and the atomic xs:string type. Its base type is the CybOX Core BaseObjectPropertyType, for permitting complex (i.e. regular-expression based) specifications. This attribute is optional and specifies the expected type for the value of the specified property. The MemoryPageProtectionEnum defines an enumeration of memory page protection constants.

From Microsoft: "Indicates committed pages for which physical storage has been allocated, either in memory or in the paging file on disk.". From Microsoft: "Indicates free pages not accessible to the calling process and available to be allocated. For free pages, the information in the AllocationBase, AllocationProtect, Protect, and Type members is undefined.". From Microsoft: "Indicates reserved pages where a range of the process's virtual address space is reserved without any physical storage being allocated. For reserved pages, the information in the Protect member is undefined.".

Its base type is the CybOX Core BaseObjectPropertyType, for permitting complex (i.e. regular-expression based) specifications.
