As shown in Fig. 1, a kind of alarm information processing method specific implementation step provided by the embodiments of the present application is as follows:
Step 101: extracting the alarm type, source IP address and purpose IP address of warning information to be graded;
When exception, attack occurs in network, the analysis to network flow that security detection equipment can generate is as a result, namely Warning information, security detection equipment here can be intrusion detection device, user subject behavioural analysis equipment, firewall and set Standby, terminal detection and response apparatus etc. can include timestamp, the source IP address, purpose of network flow in the warning information of generation The fields such as IP address, alarm type, first by the source IP in every warning information to be sorted when sorting to warning information Location, purpose IP address, alarm type information extract.
Wherein, warning information to be sorted is the warning information generated in the preset period, preset time period herein It can be as unit of minute, can also hour be unit, specifically, system O&M Security Officer can need to carry out according to business Default, after the period determines, the warning information collected in the specified period is used as warning information to be sorted.
It determines wait the warning information and after extracting related information needed of sorting, carries out following steps 102.
Step 102: obtaining and reflect the alarm type Rating Number of the alarm type frequency of occurrences, reflection the alarm letter What whether the threat source of breath first appeared threatens source Rating Number and reflects the IP address letter of IP address information association threat degree Cease Rating Number;
Wherein, the step of obtaining warning information type Rating Number are as follows: the warning information type search alarm based on extraction The mapping table of information type and warning information type Rating Number determines warning information type based on the corresponding relationship in table The mapping table of Rating Number, warning information type and warning information type Rating Number in the embodiment of the present application is preparatory Determining.
Further, it before the mapping table for determining warning information type and warning information type Rating Number, needs It determines that history threatens source, and source is threatened to be defined as the information of source IP address and alarm type to (source ip, message type).Also, if the two above field of two alarms is all identical, this two warning information belong to the same threat source; If at least one field of two above field is different, then it is assumed that two warning information are different threat sources.And history prestige When the acquisition in side of body source, it is first determined history alarm information data, the warning information generated within a preset period of time are history alarm Information such as preset time period is 7 days, then former 7 days warning information data, as history alarm information bank, is based on history alarm History required for information bank determines threatens source.
After determining history threat source, the alarm type of source IP address number and extraction different in the library of source is threatened based on history Associated source IP address number, using inverse IP associated frequencies algorithm ((Inverse IP Correlation Frequency, IICF the Rating Number for)) calculating every kind of warning information type establishes the mapping table of warning information type and Rating Number;
Determine warning information type Rating Number, statistical history first threatens IP sum N different in the library of sourceip;And for Each alarm type M, the threat source number that statistics alarm type is M, the i.e. associated source IP address number N of the alarm typem, During calculating frequency, different IP sum N is usedipAs molecule, the associated source IP address number N of the alarm typemMake For denominator.For the associated source IP address number N of the alarm typemThe case where may being 0, by denominator plus 1.Meanwhile to prevent As the associated source IP address number N of the alarm typemFrom different IP sum NipWhen equal, denominator numerical value is more than denominator numerical value, So molecule numerical value is added 1.The then Rating Number of the warning information type are as follows:
IICF (M)=log ((Nip+1)/(Nm+1))+1
The Rating Number of every kind of warning information type is determined with this calculation method, and establishes mapping table.In this Shen The frequency that a warning information type occurs in all IP please be reflected by each warning information type Rating Number in embodiment, If a warning information type source IP address more with number is associated with appearance, then it represents that this warning information is that information illustrates class A possibility that alarm or wrong report, is bigger, and threat degree is lower, its Rating Number of correspondence corresponds to lower;And if an announcement Alert information type is associated with appearance with fewer source IP, then it represents that this warning information threat degree is higher, corresponds to its grading number Value correspondence is higher.
The mapping table that warning information type Yu warning information type Rating Number are established using the method, extracts announcement The mapping table of warning information type and warning information type Rating Number is searched after alert information type, so that it may determine to accuse Alert information type Rating Number.
Further, as shown in Fig. 2, it obtains wait warning information IP address information each in the warning information that sorts grading number The step process of value is as follows:
Step 1: building association map.Firstly, the source IP address and purpose IP address of the warning information based on extraction and pre- If the source IP address and purpose IP address of the warning information in the period determine point set and line set, wherein the application is implemented The element in point set in example is different source IP address and the destination IP address, and the element of line set is source IP address With purpose IP address pair, one of source IP address and a purpose IP address constitute a member of a line as line set Element.Secondly, determining to indicate each source IP address and purpose IP address corresponding relationship based on the point set and the line set Association map;Element in association map in each line set is point and the corresponding purpose IP address of a source IP address Between line, the direction of line is to be directed toward purpose IP address by source IP address.
It is associated with map based on above-mentioned IP, an IP address grade scoring value PRi is initialized to all IP address points, uses PageRank algorithm iteration, which calculates, updates all newest PR values of IP address point.When iterate to calculate round be more than preset times when or When PageRank algorithm is restrained automatically, the PR value of obtained each node is denoted as IP address information Rating Number, finally by institute Source IP address and the average value of purpose IP address grade scoring value are the Rating Number of the IP address information.
By PageRank algorithm, the key scoring of the associated IP address association threat degree of the warning information of acquisition Value.And score value is higher, then illustrating IP address associated by the warning information, associated alarm event is more in the recent period, that is, Say that the corresponding warning information of the IP address is paid close attention to greater need for operation maintenance personnel.
Further, obtaining threat source Rating Number includes, the specific steps are as follows:
Judge whether the threat source belongs to the history and threaten source;Based on predetermined history threat source library, Determine the Rating Number in each threat source.Namely determine that threat source is that history threatens source still to increase threat source newly, wherein increasing newly Threat source represents the threat event source newly increased in network environment, the dynamic event being able to reflect in network, for example, newly The infected network host increased, it is intended to infect other hosts, the newly-increased host captured by attacker, attacker will be with this A little hosts are that springboard is attempted to attack other hosts or the network facilities, cause a large amount of network failure.Therefore, increasing threat source newly can The quickly dynamic change of positioning Cyberthreat event.
Therefore, if the source of threat belongs to the history and threatens source, it is the first numerical value that threat source Rating Number, which is arranged,;If threatening Source is not belonging to the history and threatens source, then it is second value that threat source Rating Number, which is arranged, wherein if the threat source of alarm is Newly-increased threat source, threat source the first numerical value of Rating Number determined are S1, if the threat source of alarm is that history threatens source, really The threat source Rating Number second value made is S2;Also, in the embodiment of the present application, S1 is greater than S2, for example, S1 value is When 2, S2 value is 0.1.
It is walked as follows after getting alarm type Rating Number, threat source Rating Number and IP address information Rating Number Rapid 103.
Step 103: based on alarm type Rating Number, source Rating Number and IP address information Rating Number being threatened to be added Power summation determines the warning information threat level for indicating the warning information threat degree, and is threatened based on determining warning information Grade is ranked up the warning information.
Based on alarm type Rating Number, threaten source Rating Number and IP address information Rating Number to warning information into Before row sequence, using preset algorithm, all types of score values are normalized between 0 to 1 respectively, which can To be min-max standardized method (Min-max normalization), the normalization of all Rating Numbers can be prevented some Rating Number, which crosses ambassador and finally calculates grade score value, generates big deviation, and the accuracy of grade score value calculating can be improved;To all After Rating Number is normalized, based on normalized alarm type Rating Number, source Rating Number and IP address information are threatened Rating Number, which is determined, determines a grade score value using the algorithm of weighting summation, and then determines alarm letter according to these level score value The grade threatened is ceased, the rule based on grade sequence can be to be arranged from high to low according to threat degree, can also be according to prestige Side of body degree is arranged from low to high, the embodiment of the present application to sequence rule with no restrictions.
