Description:	macOS, previously OS X, is a Unix-based graphical interface operating system (OS) developed, marketed, and sold by Apple Inc. macOS`s core is a Portable Operating System Interface (POSIX) compliant Operating System (OS) built on the XNU kernel, with standard Unix utilities available from the command line interface. It is designed to run exclusively on Mac computer hardware. Note: XNU is the computer operating system kernel developed at Apple Inc. since December 1996 for use in the macOS operating system and released as free and open source software as part of the Darwin operating system. XNU is an acronym for `X is Not Unix`.

Prior to use of this technology, users should check with their supervisor, Information Security Officer (ISO), Facility Chief Information Officer (CIO), or local Office of Information and Technology (OI&T) representative to ensure that all actions are consistent with current VA policies and procedures prior to implementation.

The VA Decision Matrix displays the current and future VA IT position regarding different releases of a TRM entry. These decisions are based upon the best information available as of the most current date. The consumer of this information has the responsibility to consult the organizations responsible for the desktop, testing, and/or production environments to ensure that the target version of the technology will be supported. Any major.minor version that is not listed in the VA Decision Matrix is considered unapproved for use.

Legend:

White	Approved: The technology/standard has been approved for use.
Yellow	Approved w/Constraints: The technology/standard can be used within the specified constraints located below the decision matrix in the footnote[1] and on the General tab.
Gray	Unapproved: This technology or standard can be used only if a POA&M review is conducted and signed by the Authorizing Official Designated Representative (AODR) as designated by the Authorizing Official (AO) or designee and based upon a recommendation from the POA&M Compliance Enforcement, has been granted to the project team or organization that wishes to use the technology.
Orange	Divest: VA has decided to divest itself on the use of the technology/standard. As a result, all projects currently utilizing the technology/standard must plan to eliminate their use of the technology/standard. Additional information on when the entry is projected to become unapproved may be found on the Decision tab for the specific entry.
Black	Prohibited: The technology/standard is not (currently) permitted to be used under any circumstances.
Blue	Planning/Evaluation Constraint:The period of time this technology is currently being evaluated, reviewed, and tested in controlled environments. Use of this technology is strictly controlled and not available for use within the general population. If a customer would like to use this technology, please work with your local or Regional OI&T office and contact the appropriate evaluation office displayed in the notes below the decision matrix. The Local or Regional OI&T office should submit an inquiry to the TRM if they require further assistance or if the evaluating office is not listed in the notes below.

Release/Version Information:

VA decisions for specific versions may include a ‘.x’ wildcard, which denotes a decision that pertains to a range of multiple versions.

For example, a technology approved with a decision for 7.x would cover any version of 7.(Anything) - 7.(Anything). However, a 7.4.x decision would cover any version of 7.4.(Anything), but would not cover any version of 7.5.x or 7.6.x on the TRM.

VA decisions for specific versions may include ‘+’ symbols; which denotes that the decision for the version specified also includes versions greater than what is specified but is not to exceed or affect previous decimal places.

For example, a technology approved with a decision for 12.6.4+ would cover any version that is greater than 12.6.4, but would not exceed the .6 decimal ie: 12.6.401 is ok, 12.6.5 is ok, 12.6.9 is ok, however 12.7.0 or 13.0 is not.

Decision Constraints


[1]	This Technology is currently being evaluated, reviewed, and tested in controlled environments. Use of this technology is strictly controlled and not available for use within the general population.

[2]	Use of this technology is only permitted when deployed using the organization`s gold image and managed by the Mac standardization project. Due to a high number of NIST security vulnerabilities, extra vigilance should be applied to ensure supported versions of the product remain properly patched to mitigate known and future vulnerabilities.

[3]	Use of this technology is only permitted when deployed using the organization`s gold image and managed by the Mac standardization project.

[4]	Due to National Institute of Standards and Technology (NIST) identified security vulnerabilities, extra vigilance should be applied to ensure the versions remain properly patched to mitigate known and future vulnerabilities. The local ISO can provide assistance in reviewing the NIST vulnerabilities.

[5]	Use of this technology is only permitted when deployed using the organization`s gold image and managed by the Mac standardization project. Version 10.12 currently being evaluated, reviewed, and tested in controlled environments. Use of this technology is strictly controlled and not available for use within the general population. Contact your local CIO office if more information is needed in regards to the use of this technology.

[6]	Use of this technology is only permitted when deployed using the organization`s gold image and managed by the Mac standardization project. Version 10.12 currently being evaluated, reviewed, and tested in controlled environments. Use of this technology is strictly controlled and not available for use within the general population. Contact your local CIO office if more information is needed in regards to the use of this technology. When establishing a password for the FileVault 2, ensure that all of the VA password requirements are met with regard to length and complexity. VA Handbook 6500 Control IA-5: Authenticator Management sets a standard of at least 8 non-blank characters. They must contain characters from three (3) of the following (4) categories: English upper case characters English lower case characters Base-10 digits Non-alphanumeric special characters Six of the characters must not occur more than once in the password. The lack of support for MFA and the reuse of OS authentication is a concern in FileVault 2. It is essential at VA to use two-factor authentication (2FA) and not duplicate OS credentials when authenticating users before system boot. Commercial add-on products must be investigated and tested for coupling with FileVault 2 to achieve MFA/2FA. Since recovery keys are essentially passwords that the system generates for the user, the user will need to find a way to secure the recovery key for later retrieval if necessary. Successful implementation of FileVault 2 relies on impeccable password protection. VA must consistently conduct awareness programs emphasizing techniques to store/escrow passwords and recovery keys. Thoroughly test centralized management and configuration third-party add-on pairings that must be used to scale FileVault 2 implementation from its intended personal use to an enterprise solution. Care must be exercised to use the latest version of FileVault 2 and not to inadvertently implement Legacy FileVault by mistake. FileVault 2 must remain patched and operated in accordance with Federal and Department security and privacy policies and guidelines.

Name	Description
FileVault	FileVault 2 is a disk encryption program that provides full disk encryption capabilities (FDE) to macOS desktop and laptop hard drives. It is used also to support Apple mobile-related products that use iOS, such as iPhones and iPads. FileVault 2 encrypts all data on hard drives to guard against unauthorized user access to sensitive data. XTS-AES-128 encryption is utilized with support for 256-bit AES keys for the macOS versions 10.9 and later. Legacy FileVault (the version prior to 2013) only supported the use of 128-bit keys.
