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.
