In some implementations, a host processor associated with a vehicle may select, from a plurality of devices that are configured to communicate with the host processor for performing security functions, a first device to serve as a primary device and a second device to serve as a secondary device. The first device may include a first memory with an embedded hardware security module and may be associated with a first set of nodes of the vehicle. The second device may include a second memory with an embedded hardware security module and may be associated with a second set of nodes of the vehicle. The host processor may determine, based on a signal, a failure associated with the first device or the second device. The host processor may initiate a remediation process based on the failure associated with the first device or the second device. Numerous other implementations are described.
