- Security Architectural Protocol as defined in the DXE CIS\r
-\r
- Used to provide Security services. Specifically, dependening upon the \r
- authentication state of a discovered driver in a Firmware Volume, the \r
- portable DXE Core Dispatcher will call into the Security Architectural \r
- Protocol (SAP) with the authentication state of the driver.\r
-\r
- This call-out allows for OEM-specific policy decisions to be made, such\r
- as event logging for attested boots, locking flash in response to discovering\r
- an unsigned driver or failed signature check, or other exception response.\r
-\r
- The SAP can also change system behavior by having the DXE core put a driver\r
- in the Schedule-On-Request (SOR) state. This will allow for later disposition \r
- of the driver by platform agent, such as Platform BDS.\r

- The EFI_SECURITY_ARCH_PROTOCOL (SAP) is used to abstract platform-specific \r

- given status for the authentication check from the section extraction protocol. \r
-\r
- The possible responses in a given SAP implementation may include locking \r
- flash upon failure to authenticate, attestation logging for all signed drivers, \r
- and other exception operations. The File parameter allows for possible logging \r
- within the SAP of the driver.\r

- If the file specified by File with an authentication status specified by \r
- AuthenticationStatus is not safe for the DXE Core to use under any circumstances, \r
- then EFI_ACCESS_DENIED is returned.\r
-\r
- If the file specified by File with an authentication status specified by \r
- AuthenticationStatus is not safe for the DXE Core to use right now, but it \r

- @par Protocol Description:\r
-\r
- The EFI_SECURITY_ARCH_PROTOCOL is used to abstract platform-specific policy\r
- from the DXE core. This includes locking flash upon failure to authenticate, \r
- attestation logging, and other exception operations.\r
-\r
- The driver that produces the EFI_SECURITY_ARCH_PROTOCOL may also optionally \r
- install the EFI_SECURITY_POLICY_PROTOCOL_GUID onto a new handle with a NULL \r
- interface. The existence of this GUID in the protocol database means that \r
- the GUIDed Section Extraction Protocol should authenticate the contents of \r
- an Authentication Section. The expectation is that the GUIDed Section \r
- Extraction protocol will look for the existence of the EFI_SECURITY_POLICY_ \r
- PROTOCOL_GUID in the protocol database. If it exists, then the publication \r
- thereof is taken as an injunction to attempt an authentication of any section \r
- wrapped in an Authentication Section. See the Firmware File System \r
- Specification for details on the GUIDed Section Extraction Protocol and \r
- Authentication Sections.\r
-\r
- @par Protocol Parameters:\r
-\r
- FileAuthenticationState - This service is called upon fault with respect to \r
- the authentication of a section of a file.\r
