Specification of Intrusion Detection System Manager, No.977, CP, AUTOSAR R22-11, CP, 20230421

Posted at

AUTOSARは自動車用OSの業界団体規格です。 
業務で利用する場合には、会員になることを条件にしています。

2002年から20年経ち、当初の狙いの段階に近づいてきました。

MATLABでモデルさえ記述すれば、あとは自動生成だけでソフトが完成するところまで、あと一歩です。
Ethernet, UNIXが生まれて20年で大衆化したのと同じように考えると分かりやすいでしょう。 

AUTOSARの上で動く、クラウド対応のミドルウェアが出て、開発も運用もクラウドになれば、一気にAUTOSARは大衆化するでしょう。

Context Data Buffer Buffer with variable sizes to fit to the needs of the context data of the SEvs.
Context Data Relevant information to a SEv. It is optional data that provides a broader understanding of the security event (e.g. the corrupted data ). The content and encoding of the context data is externally defined by the sensor and unknown to the IdsM module.
Event Buffer Buffer to temporarily store the reported SEv IDS.
Filter A modifier of the security events which can drop or alter an incoming SEv.
Filter Chain One configured sequence of filters.
IdsM block state State reported by the BswM via IdsM_BswM_StateChanged. The states are used to suspend the collection of security events.
Intrusion Detection System Manager The Intrusion Detection System Manager handles security events reported by security sensors.
IdsR The IdsR is an OEM specific adaptive application that can be used to further propagate the QSEvs to the SOC.
Qualified Security Event (QSEv) Events that have passed their corresponding filter chain and are sent to the configured sink.
Security Event (SEv) On-board Security Events are instances of security event types which are reported by BSW or SW-C to the IdsM. They are structured data originating from a sensor which serve as fundamental input and output data format for filters. These reported events to the IdsM that are indicative of an ongoing attack or are somehow suited to assess the security state of the vehicle. This means that events can occur during the normal operation without any ongoing attack.
Security Event Type A security event type can be identified by its security event type ID. Instances of security event types are called security events and share the same security event type ID.
Sem Security event memory is a Dem Module user defined memory which is separated from the Dem’s primary memory.
Sensor Reporting identity that informs the IdsM module about SEvs. It can be a BSW Module, a proprietary CDD or an SW-C Application.
Sink Destination of a QSEv. Depending on the configuration the QSEv can be persisted, propagated or both.
Timestamp Provider Service or SW-Component which provides a TimeStamp. e.g. in CP Stbm.
