Intrusion Detection System protocol	The IDS protocol specifies the message format which is used by IDS.
Intrusion Detection System Message	Message which is send by the IdsM with the IDS protocol.
Intrusion Detection System Manager	The Intrusion Detection System Manager handles security events reported by security sensors.
Intrusion Detection System Reporter	The Intrusion Detection System Reporter handles Qualified Security Events received from IdsM instances.
I-PDU Multiplexer	An AUTOSAR Basic Software module which specifies the protocol to multiplex multiple Pdus with one Protocol Control information.
LIN	Local Interconnect Network: serial communication bus to connect sensors and actuators.
Protocol Data Unit Router	An AUTOSAR component responsible for routing of messages independent from underlying communication network.
Protocol Requirement Specification Intrusion Detection System	The specification document which describes all elements of the IDS protocol.
Qualified Security Event (QSEv)	Security events which pass their filter chain are regarded as Qualified Security Events and are sent to the configured sink.
Security Extract	The Security Extract specifies which security events are handled by IdsM instances and their configuration parameters.
Security Events	Onboard security events are reported by BSW, CDD, SWC or other software components or applications to the IdsM.
Security Event Memory	A user defined diagnostic event memory which is independent from the primary diagnostic event memory.
Security Sensorsv	BSW, CDD, SWC or other software components or applications which report security events to the IdsM.
Security Incident and Event Management	Technology concept to collect, correlate and analyze security incidents to detect a threat.
Sensor	Reporting identity that informs the IdsM module about SEvs. It can be a BSW module, a proprietary CDD or a SWC Application.
Security Operation Centre	Security Operation Center is the Backend of the IDS in which data can be processed and analysed.
Socket Adapter	Socket Adaptor is a Basic Software module of AUTOSAR which creates interface between Pdu-Based communication on service level and socket based TCP/IP
