			<short_description>The following defines types for default controlled vocabularies used within MAEC. An individual vocabulary may be revised at any time. Revisions to vocabularies will result in the creation of new types with the new version number embedded in the name of those types. Vocabularies can be reference from MAEC elements through the use of xsi:Type. The individual elements where this may be done indicate the expected default vocabulary.</short_description>

                <xs:annotation>
                    <xs:documentation>The 'rootkit' value generally refers to a method of hiding files or processes from normal methods of monitoring, and is often used by malware to conceal its presence and activities. Originally, the term applied to UNIX-based operating systems - a root kit was a collection of tools to enable a user to obtain root (administrator-level) access to a system and conceal any changes they might make. Such tools often included trojanized versions of standard monitoring software which would hide the root kit operators' activities. More recently the term has generally been applied to malware using stealth techniques. Rootkits can operate at a number of levels, from the application level - simply replacing or adjusting the settings of system software to prevent the display of certain information - through hooking certain functions or inserting modules or drivers into the operating system kernel, to the deeper level of firmware or virtualization rook kits, which are activated before the operating system and thus even harder to detect while the system is running.</xs:documentation>
