Intrusion Detection Alarm System the problems such as quantity is more, false alarm or invalid alarm are more there is alarm mostly at present,
And cause this problem a main cause be parameter alarm threshold value unreasonable setting, if alarm threshold value is excessive, it is possible to
Some important alarms can be missed；Conversely, threshold value is too small, excessive invalid alarm can be caused, under multi-sensor environment, this
It is a little particularly problematic.In order to improve the performance of intrusion alarm system, it is necessary to optimize setting to the alarm threshold value of its parameter.
Most common threshold setting method is 3 σ (three times standard deviation) method in practical application, i.e. threshold range is scheduled on [+3 σ of μ -3 σ, μ]
In section, the parameter setting in the range of this is regarded as exceptional value, can trigger alarm.
The present embodiment establishes alarm threshold value using Density Estimator method and the functional relation of wrong report, miss probability is expressed
Formula, it is proposed that the new method that procedure parameter alarm threshold value is set, it contains the estimation of procedure parameter alarm condition and procedure parameter
Alarm threshold value optimizes two stages.
First stage：Procedure parameter alarm condition is estimated
In order to set rational alarm threshold value, it is necessary first to the alarm condition of estimation procedure parameter, mainly false alarm and
Fail to report alert problem.
The step of procedure parameter alarm condition based on cuclear density is estimated is as follows：
The first step, the pretreatment of data：Normalized is done to original data, data are limited in the range of [0,1],
Such as：
WhereinFor the data after normalization,、The respectively minimum value and maximum of initial data, n are data
Number；
Second step, optimal bandwidth h's asks for：Window width is a parameter critically important in Density Estimator, its size is straight
Connecing influences the accuracy of estimated result.Most efficient method is the thought based on least square error at present, works as integrated square error
（MISE）When minimum, obtained window width is optimal, and the calculation formula of one-dimensional optimal bandwidth is：
Wherein, n is sample number；
3rd step, the estimation of procedure parameter probability density：The kernel function of Gaussian is selected, the probability of estimation procedure parameter is close
Degree, obtains procedure parameter probability density function curve, and a part of normal data is more than alarm threshold value, just generates false alarm, generally
Rate is exactly to exceed the region area of alarm threshold value part under normal distribution curve；And a part of abnormal data is less than alarm threshold value,
Belong to and fail to report, fail to report alert probability to be less than the region area of alarm threshold value part under abnormal data distribution curve.
According to minimal error rate Bayesian decision theory, false alarm can be by following expression with the probability for failing to report alert generation
Formula calculates：
,
Wherein,For the probability density function expression formula of normal condition,It is close for the probability of abnormality
Function expression is spent, t is alarm threshold value.As can be seen that if alarm threshold value sets excessive, the probability of false alarm if, becomes smaller, and
Alert probability is failed to report then to become larger；Conversely, when alarm threshold value sets too small, the probability that false alarm occurs increases, and fails to report alert
Probability can reduce.
Second stage：Procedure parameter alarm threshold value optimizes
Regard the setting of alarm threshold value as an optimization problem, be described as follows：
,,
Its algorithm realizes that step is as follows：
The first step, section, construct at 2 points,；
Second step, if, then the region of search be reduced into,, judgeWhether into
It is vertical, the 4th step is gone to if set up, otherwise returns to the first step；
3rd step, if, then the region of search be reduced into,, judgeWhether into
It is vertical, the 4th step is gone to if set up, otherwise returns to the first step；
4th step, optimal solution are, object function minimum value is。
Alarm threshold value algorithm writes Intelligent warning device by writing program.The software of design is mainly big comprising following four
Module：
Preprocessing module mainly carries out Mathematical treatment to the initial data of procedure parameter, that is, normalizes so that after processing
Data can meet requirement of next module to data format.
Density estimation module, as input, to join by pretreated data with the method estimation procedure of cuclear density
Several probability density obtains normal and abnormality function curve.
Function Fitting module according to density function curve, fits the probability density function expression formula for meeting Gaussian Profile,
Establish the object function of threshold optimization.
Threshold value solves module, and object function is solved using the method for numerical optimization, exports excellent alarm threshold value.
The above is the preferred embodiment of the utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of principle described in the utility model is not departed from, several improvements and modifications can also be made, these improvement
The scope of protection of the utility model is also should be regarded as with retouching.
