+| SEC_005 a| The Server SoC MUST comply with the requirements and guidelines
+             detailed in Reference Model, Ecosystem Security Objectives, and
+             the Cryptography sections of the RISC-V Security Model cite:[SEC].
+             The Server SoC is classified as a complex security system for the
+             purposes of SR_ROT_001 and SR_ATT_002.

+| SEC_006 a| The Server SoC MUST support the Generic System Without Supervisor
+             Domains use case detailed in the RISC-V Security Model. The
+             building blocks used to implement this use case MUST comply with
+             the requirements specified in the RISC-V Security Building Blocks
+             section of the RISC-V Security Model specification.
