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 lead
A main cause for causing this problem is the unreasonable setting of parameter alarm threshold value, if alarm threshold value is excessive, it is possible to can leak
Fall some important alarms；Conversely, threshold value is too small, excessive invalid alarm can be caused, under multi-sensor environment, these are asked
Inscribe especially prominent.In order to improve the performance of intrusion alarm system, it is necessary to optimize setting to the alarm threshold value of its parameter.It is actual
The most frequently used threshold setting method is 3 σ (three times standard deviation) method in, i.e. threshold range is scheduled on the section of [μ -3 σ, μ+3 σ]
Interior, 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：
Wherein xiFor the data after normalization, xmin、xmaxThe 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 direct shadow of size
Ring 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：
WhereinN is sample number；
3rd step, the estimation of procedure parameter probability density：The kernel function of selection Gaussian, the probability density of estimation procedure parameter,
Procedure parameter probability density function curve is obtained, a part of normal data is more than alarm threshold value, just generates false alarm, probability is just
It is the region area for exceeding alarm threshold value part under normal distribution curve；And a part of abnormal data is less than alarm threshold value, belong to
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 reached with the probability for failing to report alert generation by following table
Formula calculates：
Wherein, f (x | ω1) be normal condition probability density function expression formula, f (x | ω2) be abnormality probability density
Function expression, t are alarm threshold value.As can be seen that if alarm threshold value setting is excessive, the probability of false alarm then diminishes, and leaks
The probability of alarm then becomes big；Conversely, when alarm threshold value sets too small, probability increase that false alarm occurs, and fail to report alert general
Rate 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：
MinF (x)=P1(e)+P2(e)
Its algorithm realizes that step is as follows：
The first step, section [a, b], construct two point x1=a+0.382 (b-a), x2=a+0.618 (b-a)；
Second step, if F (x1) ＜ F (x2), then the region of search is reduced into [a, x2], b=x2, judge | x2-x1| whether ＜ ε set up,
If establishment goes to the 4th step, the first step is otherwise returned；
3rd step, if F (x1)≥F(x2), then the region of search is reduced into [x1, b], a=x1, judge | x2-x1| whether ＜ ε set up,
If establishment goes to the 4th step, the first step is otherwise returned；
4th step, optimal solution areObject function minimum value is F (x*)。
Alarm threshold value algorithm writes Intelligent warning device by writing program.The software of design mainly includes following four module：
Pretreatment module, Mathematical treatment mainly is carried out to the initial data of procedure parameter, that is, normalized so that the number after processing
According to requirement of next module to data format can be met.
Density estimation module, as input, to join by pretreated data with the method estimation procedure of cuclear density
Several probability density, obtain normal and abnormality function curve.
Function Fitting module, according to density function curve, the probability density function expression formula for meeting Gaussian Profile is fitted, established
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.
Described above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, on the premise of principle of the present invention is not departed from, some improvements and modifications can also be made, these improvements and modifications
It should be regarded as protection scope of the present invention.
