Component compatibility analysis prevents subtle mismatches that compromise security functions. Before integrating a new radio or star tracker, simulate combined loads on power buses, processor cycles, and memory partitions, then verify task-scheduling margins and watchdog timeouts still meet worst-case latencies. Document results in the interface control database and rejects any device whose drivers require privilege escalations that violate least-privilege assumptions baked into earlier assurance steps.
The [organization] shall develop, document, and maintain under configuration control, a current baseline configuration of the spacecrafts.{CM-2,CM-3(7),CM-4(2),CM-6,SA-8(30),SA-10}
The [organization] shall maintain the integrity of the mapping between the master build data (hardware drawings and software/firmware code) describing the current version of hardware, software, and firmware and the on-site master copy of the data for the current version.{CM-6,SA-8(21),SA-8(30),SA-10,SA-10(3),SA-10(4),SA-10(5),SI-7(10),SR-4(4)}
The [organization] shall document the platform's security architecture, and how it is established within and is an integrated part of the overall [organization] mission security architecture.{PL-7,SA-8(7),SA-8(13),SA-8(29),SA-8(30),SA-17}
The [organization] shall document and design a security architecture using a defense-in-depth approach that allocates the [organization]s defined safeguards to the indicated locations and layers: [Examples include: operating system abstractions and hardware mechanisms to the separate processors in the platform, internal components, and the FSW].{SV-MA-6}{CA-9,PL-7,PL-8,PL-8(1),SA-8(3),SA-8(4),SA-8(7),SA-8(9),SA-8(11),SA-8(13),SA-8(19),SA-8(29),SA-8(30)}
