Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of security management, and in particular to an integrated enterprise security management system and method. Background Art
[0002] With the development of enterprise informatization and intelligence, the security management needs within enterprises are becoming more complex and diversified. Traditional enterprise security management systems are usually based on a single functional module, focusing on specific security measures such as fire prevention, theft prevention, and anti-virus. However, with the expansion of enterprise scale and the increase of office areas, this single modular management method has been difficult to cope with actual security needs. Especially in large and medium-sized enterprises, the security requirements of different office areas may vary greatly, and the flow of personnel and physical connections between areas significantly increase the complexity of security management. Based on these realities, integrated enterprise security management methods have gradually become the focus of research and application. In the existing technology, most enterprises adopt a decentralized security management method, in which each office area is managed independently and acts independently, lacking an overall security management strategy, which easily leads to blind spots or loopholes in security management.
[0003] However, existing enterprise security management technologies have obvious shortcomings when faced with complex correlations and differences in security levels among office areas. First, most systems are unable to dynamically analyze and update the correlations between office areas in real time, which makes the security management system appear rigid and lagging in the corporate environment with frequent personnel turnover. Second, existing technologies usually ignore the similarities and differences in security levels between office areas, which is crucial in emergency situations (such as fire, earthquake, etc.). If these factors are not taken into account, it is impossible to reasonably optimize the emergency linkage mechanism between areas, resulting in one-sided and inefficient security management. In addition, the lack of an effective standardized method to quantify and analyze these complex factors further limits the comprehensiveness and adaptability of the security management system. Therefore, developing an enterprise security management method that can integrate and analyze the correlation between office areas and the similarity of security levels has become an urgent problem to be solved. Summary of the invention
[0004] The purpose of the present invention is to provide an integrated enterprise security management system and method to solve the problems raised in the above background technology.
[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0006] An integrated enterprise security management method includes the following steps: dividing the enterprise space into office areas based on all office areas in the enterprise space; generating a time series in days and collecting personnel flow data generated in the office areas at different time points; constructing an office area topology map based on the office areas and calculating the security level of the office areas; calculating the correlation between the office areas based on the personnel flow data; calculating the security level difference and normalizing it into security level similarity; designing a security risk assessment value according to the correlation and the security level similarity, and analyzing and outputting a linkage security alarm pair.
[0007] As a preferred solution of the integrated enterprise security management method described in the present invention, based on all office areas in the enterprise space, the enterprise space is divided into office areas, and an office area set SR = {SR i |i∈[1,I]}, where SR i represents the i-th office area, and I is the total number of office areas.
[0008] Generate a time series T={t y |y∈[1,Y]}, where t y is the yth time point, Y is the total number of time points; collect time points t y At time t y+1 Office area SR j The personnel flow data generated includes the personnel flow data of entering the office area SR j The number of people flowing in and leaving the office area generated by j The personnel outflow generated at the time is recorded as the personnel inflow data and personnel outflow data
[0009] As a preferred solution of the integrated enterprise security management method described in the present invention, the office area set SR = {SR i |i∈[1,I]} is used as a vertex set and the connection relationship between office areas is used as an edge set to construct an office area topology map. The connection relationship is a physical connection between office areas, and the physical connection includes a connection based on doors, a connection based on corridors, and a connection based on stairs.
[0010] Based on the office area topology map, calculate the office area SR i The security level of the SR i )|i∈[1,I]}, where L(SR i ) indicates office area SR i The safety level is calculated as follows:
[0011]
[0012] Where n represents the office area SR i The nth office area connected, P in Indicates the office area SR after statistics i With office area SR n The number of connections between in Indicates the office area SR after statistics i With office area SR n The distance between i ) indicates office area SR i is the safety level, and β is the preset attenuation coefficient.
[0013] In the present invention, the number of connections P in Represents the number of connections between office areas. The more connections there are, the safer it is that in the event of an emergency or when a certain path has problems, office areas can rely on other paths for communication and evacuation. It reflects the impact of distance on the safety level. The exponential decay makes the contribution of farther areas to the safety level significantly weakened, while the contribution of closer areas is relatively larger.
[0014] As a preferred solution of the integrated enterprise security management method described in the present invention, based on the personnel inflow data and the personnel outflow data Calculate office area SR i and office area SR j The relationship between H(SR i , SR j ), the calculation formula is:
[0015]
[0016] in, Indicates time point t y At time t y+1 Enter the office area SR i Data on the flow of people, Indicates time point t y At time t y+1 Leave the office area at SR j The flow of people data, H(SR i , SR j ) indicates office area SR i and office area SR j The correlation relationship between them.
[0017] In the present invention, by calculating the association relationship, it can be determined whether there is a strong association relationship between two office areas. The value range of the association relationship is between [0, 1]. The closer the value of the association relationship is to 1, the stronger the association relationship is between the two office areas, that is, the personnel flow patterns are very similar.
[0018] Preset correlation threshold θ, if H(SR i , SR j )>θ, then the office area SR is determined i and office area SR j There is a strong correlation between them.
[0019] Based on the security level set SL={L(SR i )|i∈[1,I]}, calculate the office area SR i and office area SR j The security level difference between them is calculated as SLD = |L(SR i )-L(SR j )|.
[0020] The preset security level difference threshold ε, if SLD < ε, then the office area SR is determined i and office area SR j The similarity of security levels is strong.
[0021] The security level difference SLD is normalized to the security level similarity SLS ij , the standardized formula is This formula converts the security level difference into a similarity value between 0 and 1. The larger the security level difference SLD, the higher the similarity SLS. ij The smaller the security level difference SLD, the smaller the similarity SLS. ij The bigger.
[0022] As a preferred solution of the integrated enterprise security management method described in the present invention, the security risk assessment value is designed and calculated as follows:
[0023] C ij =α·H(SR i , SR j )+(1-α)·SLS ij ;
[0024] Among them, C ij represents the security risk assessment value, and α is the preset weight coefficient, which is used to adjust the relative importance of the similarity of personnel flow characteristics and the similarity of security levels.
[0025] In the present invention, by collecting personnel flow data at different time points and in different office areas, the association relationship H(SR i , SR j ) is calculated, and the security level similarity SLS is calculated based on the security level ij , through the association relationship H(SR i , SR j ) and security level similarity SLS ij To evaluate the overall correlation between the two office areas, the comprehensive score C ij If the comprehensive score is C ij The larger the value, the stronger the connection between the two office areas. It is judged that the company needs to establish a closer safety linkage mechanism between the two areas, such as coordinating evacuation routes, placing fire hydrants and fire extinguishers between areas, and synchronizing emergency plans to prevent emergencies such as fire from spreading from one area to another.

[0059] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0060] See also Figure 1-Figure 2 , the present invention provides a technical solution:
[0061] See also Figure 1 In the first embodiment of the present invention, an integrated enterprise security management method is provided, the method comprising the following steps:
[0062] Step S1: Based on all office areas in the enterprise space, the enterprise space is divided into office areas; a time series is generated in days, and personnel flow data generated in the office areas at different time points are collected.
[0063] Specifically, based on all office areas in the enterprise space, the enterprise space is divided into office areas, and an office area set SR = {SR i |i∈[1,I]}, where SR i represents the i-th office area, and I is the total number of office areas.
[0064] Generate a time series T={t y |y∈[1,Y]}, where t y is the yth time point, Y is the total number of time points; collect time points t y At time t y+1 Office area SR i The personnel flow data generated includes the personnel flow data of entering the office area SR i The number of people flowing in and leaving the office area generated by i The personnel outflow generated at the time is recorded as the personnel inflow data and personnel outflow data
[0065] Step S2: constructing an office area topology map based on the office area, and calculating the security level of the office area.
[0066] Specifically, the office area set SR = {SR i |i∈[1,I]} is used as a vertex set and the connection relationship between office areas is used as an edge set to construct an office area topology map. The connection relationship is a physical connection between office areas, and the physical connection includes a connection based on doors, a connection based on corridors, and a connection based on stairs.
[0067] Based on the office area topology map, calculate the office area SR i The security level of the SR i )|i∈[1,I]}, where L(SR i ) indicates office area SR i The safety level is calculated as follows:
[0068]
[0069] Where n represents the office area SR i The nth office area connected, P inIndicates the office area SR after statistics i With office area SR n The number of connections between in Indicates the office area SR after statistics i With office area SR n The distance between i ) indicates office area SR i is the safety level, and β is the preset attenuation coefficient.
[0070] For example, assuming there are three office areas and β is 0.1, when i is 1, let P 12 =3, P 13 is 5, d 12 is 5, d 13 is 10, and we can get L(SR 1 )=(3*e -0.1·5 )+(5*e -0.1·10 )≈3.7; when i is 2, let P 21 =3, P 23 is 4, d 21 is 5, d 23 is 7, substituting into the formula to obtain L(SR 2 )=(3*e -0.1·5 )+(4*e -0.1·7 )≈3.8; it can be concluded that the office area SR 2 The safety level is higher than that of the office area SR 1 To be high.
[0071] Step S3: Based on the personnel flow data, the association relationship between office areas is calculated; the security level difference is calculated and normalized into the security level similarity.
[0072] Specifically, based on the personnel inflow data and the personnel outflow data Calculate office area SR i and office area SR j The relationship between H(SR i , SR j ), the calculation formula is:
[0073]
[0074] in, Indicates time point t y At time t y+1 Enter the office area SR i Data on the flow of people, Indicates time point t y At time t y+1Leave the office area at SR j The flow of people data, H(SR i , SR j ) indicates office area SR i and office area SR j The correlation relationship between them.
[0075] In the present invention, by calculating the association relationship, it can be determined whether there is a strong association relationship between two office areas. The value range of the association relationship is between [0, 1]. The closer the value of the association relationship is to 1, the stronger the association relationship is between the two office areas, that is, the personnel flow patterns are very similar.
[0076] For example, suppose that at time t 1 At time t 2 Office area SR 1 Personnel inflow data 50, personnel outflow data 40, office area SR 2 Personnel inflow data 45, personnel outflow data is 35, and we can get The result is very close to 1, indicating that the mobility patterns of the two regions are very similar.
[0077] Preset correlation threshold θ, if H(SR i , SR j )>θ, then the office area SR is determined i and office area SR j There is a strong correlation between them.
[0078] Further, based on the security level set SL={L(SR i )|i∈[1,I]}, calculate the office area SR i and office area SR j The security level difference between them is calculated as SLD = |L(SR i )-L(SR j )|.
[0079] The security level difference threshold ε is preset. If SLD<ε, the office area is determined to be SR i and office area SR j The similarity of security levels is strong.
[0080] The security level difference SLD is normalized to the security level similarity SLS ij , the standardized formula is This formula converts the security level difference into a similarity value between 0 and 1. The larger the security level difference SLD, the higher the similarity SLS. ij The smaller the security level difference SLD, the smaller the similarity SLS. ij The bigger.
[0081] For example, assuming that the security level difference threshold ε is 0.5, SLD = |3.7-3.8| = 0.1, SLD<ε, determine the office area SR 1 and office area SR 2 The similarity of security levels is strong.
[0082] Step S4: designing a security risk assessment value according to the association relationship and the security level similarity, analyzing and outputting a linkage security alarm pair.
[0083] Specifically, the design safety risk assessment value is calculated as follows:
[0084] C ij =α·H(SR i , SR j )+(1-α)·SLS ij ;
[0085] Among them, C ij represents the security risk assessment value, and α is the preset weight coefficient, which is used to adjust the relative importance of the similarity of personnel flow characteristics and the similarity of security levels.
[0086] In the present invention, by collecting personnel flow data at different time points and in different office areas, the association relationship H(SR i , SR j ) is calculated, and the security level similarity SLS is calculated based on the security level ij , through the association relationship H(SR i , SR j ) and security level similarity SLS ij To evaluate the overall correlation between the two office areas, the comprehensive score C ij If the comprehensive score is C ij The larger the value, the stronger the connection between the two office areas. It is judged that the company needs to establish a closer safety linkage mechanism between the two areas, such as coordinating evacuation routes, placing fire hydrants and fire extinguishers between areas, and synchronizing emergency plans to prevent emergencies such as fire from spreading from one area to another.
[0087] Preset comprehensive score threshold like In the office area SR iand office area SR j Build a linkage security alarm pair (SR i , SR j ).
[0088] For example, if the weight coefficient α is 1, the comprehensive score threshold is 1, and we can get C 12 =0.8889+0.5·0.9≈1.34, then In the office area SR 1 and office area SR 2 Build a linkage security alarm pair (SR 1 , SR 2 ).
[0089] Specifically, for the linkage safety alarm pair (SR i , SR j ), set the following rules:
[0090] Unify and adjust the security policies and management measures of these areas.
[0091] Strengthen office area SR i and office area SR j Monitoring of personnel flow between them.
[0092] For office areas that have a strong correlation but low similarity in security levels, set the following rules:
[0093] Implement stricter access control measures.
[0094] Implement stricter access control measures.
[0095] Provide additional safety training to personnel who frequently move between these areas.
