These 6 specifications are the following (see figure 1 summarizing the various concepts involved in event detection and interactions

20、 how to produce indicators and how to detect the related events with various means and methods (with a classification of the main categories of use cases/symptoms), - ETSI GS ISI 005 addressing ways to test the effectiveness of existing detection means within an organization, which is a more detaile

44、ssessment of detection effectiveness 4.1.0 Introduction on assessment of detection effectiveness The objective of testing security event detection systems is to be able to assess the effectiveness of the detection functionality. This evaluation can be performed in a laboratory (the detection system

45、under test is not connected to an operational system) or in real operation (the detection system under test is connected to the real operational system). Detection capability testing can be done before the deployment of the detection system. Test campaigns can also be organized regularly to assess t

46、he sustainability of the detection capability. It should be noted that when detection capabilities are outsourced, specific audit clauses have to be defined in the contract. The result of the assessment is not a single result but a set of both quantities and qualitative data. 4.1.1 Examples of quant

47、itative results 4.1.1.1 Detection level This measurement determines the rate of security events detected correctly by the SUT in a given environment during a particular time frame. The accuracy of that detection level is directly based on the sample of events used to perform the measurement. Due to

48、the fact that as of today no standardized sample database exists, current published detection levels are not comparable between each other. The other reason why results are not comparable is due to the fact that the detection level is directly linked to the detection rules configured in the tools (I

49、DS, SIEM). The list of configured rules depends on each particular deployment and not on the installed tools. 4.1.1.2 Coverage of events specified in ETSI GS ISI 001-1 ETSI GS ISI 001-1 i.8 specifies a list of events that may be detected in order to generate accurate indicators. The measurement of the detection level could be the amount (in percent) of security events that the system under test can detect compared to the list specified in the ETSI GS ISI 001-1 i.8. 4.1.1.3 False-positive rate This measurement determine
