## Abstract

With the continuous deepening of Chinese medical and health system reform, hospital informatization construction is advancing by leaps and bounds, especially in the context of “Internet of Things + Medical,” hospital informatization construction has made significant progress. However, computer network security management and maintenance work still face many contradictions and problems, and we need to pay attention to them. Based on the analysis of the current situation of computer network security management and maintenance in hospital information construction, this paper focuses on the problems of computer network security management and maintenance and proposes targeted optimization countermeasures. Based on the current problems faced by the medical industry in our country and the state’s support for the medical Internet of Things, this paper studies the application of the Internet of Things in hospital information management at home and abroad. This article uses hospital information network security maintenance evaluation methods and evaluation indicators to conduct an empirical analysis of the information security maintenance level of these 12 hospitals, from the risk assessment of hospital information network security, the establishment of strategies, the level of information security software and hardware equipment, and the information security personnel. Experiments show that 58.33% of the hospitals surveyed have only done part of the work on risk analysis and risk assessment of their own network information security, and 41.67% of the hospitals have not done this work at all. This shows that hospitals should incorporate computer network security management and maintenance into the information construction system, focusing on the outstanding problems and possible risks faced by the arm’s computer network security management and maintenance, and vigorously promote the reform and innovation of computer network security management and maintenance.

## 1. Introduction

In the new era of rapid development of the Internet of Things in my country, hospital informatization construction is accelerating, and hospital informatization construction has shown outstanding characteristics such as networking and intelligence. However, there are still many aspects that are not in place in the specific implementation process. The lack of understanding of the important value of computer network security management and maintenance in hospitals in China has directly led to many problems in their work. This requires hospitals to adopt more effective methods and strategies to promote computer network security management and maintenance work to achieve better results in the process of informatization construction in the future. Through questionnaires, interviews, and other methods to investigate the application status of the Internet of Things in hospital informatization management, analyze the existing problems, combine the current situation of the sample hospitals, put forward targeted countermeasures and suggestions, and find a suitable solution for the sample hospitals. It is a new way of thinking that can keep up with the development of modern hospitals. From a practical point of view, some useful discussions are made for the application of the Internet of Things in hospital information management under the new situation, and it has a certain reference for other hospitals to develop the application of the Internet of Things in hospital information management.The construction of hospital informatization has a strong role in changing the traditional medical service model. Under the current historical conditions of accelerated advancement of hospital informatization and continuous reform and innovation, the application of the network has become more and more extensive. Only by vigorously strengthening the management and maintenance of computer network security can the hospital informatization construction achieve better results. To be able to prevent and control possible network security risks, hospitals should have a clear understanding of this. The informatization construction of the hospital is also one of the important manifestations of the enhancement of the core competitiveness of the hospital, which is conducive to the sustainable and healthy development of the hospital. However, in the process of informatization construction in various hospitals, a little carelessness will cause certain network security problems to appear and bring security risks to the informatization construction of hospitals. The medical Internet of Things is the trend of hospital informatization development. This research is a survey of the applications that have been used in sample hospitals. Although the application of the research is limited, it has a certain reference value for other hospitals on the construction and application of the Internet of Things.Hyden et al. proposed that the wireless network has evolved from a single wireless personal area network to a wireless wide area network. The coverage has been expanded from a few meters to the world, and the transmission speed has also doubled. The network is gradually integrated into the medical industry and has unique advantages in telemedicine, doctor visits, and clinical care. It can improve employee productivity, reduce operating costs, avoid duplication of work or errors, and give full play to the functions of the hospital information system. Effectively improve the quality of medical care and strengthen the communication between doctors and patients so as to obtain better treatment and care, but his research did not clearly propose how to specifically and effectively improve the quality of medical care [1]. Baykara and Das conducted a survey of ten hospitals, and the informatization construction funds of each hospital are related to the hospital’s business income. The funds for software and hardware have increased relatively. The construction of the hospital information subsystem is different. Each hospital has inserted more than two types of networks: medical insurance and the Internet. The government should increase basic capital investment. The Information Center of the Health Bureau should give full play to its functions, unify standards and plans, strengthen the construction of computer teams, and train medical staff in computer knowledge. An open and stable health information platform integrates clinical management and hospital management into an organic whole. However, its overall research lacks data support and needs more data to support its conclusions [2]. Mansouri and Bouhlel proposed that information technology has become a representative of the scientific revolution. In the medical field, network security management and maintenance of hospital information systems is a new development trend. At present, my country is paying more and more attention to medical safety, and relevant medical institutions are facing huge challenges. However, this is an opportunity for the security management and maintenance of the hospital information system network. On this basis, starting from the concept of the Internet and the relationship between the Internet and the hospital information system, the network security management and maintenance of the hospital information system is researched. The experimental results lack more data support so that the network in the hospital information construction the level of safe maintenance remains in doubt [3]. Mikailova et al. believe that today, information technology (IT) occupies an increasingly stable position in the work organization process of various companies, especially medical institutions. Today’s scientific community has begun to investigate the theme of incorporating IT integration features into health organizations [4]. The above scholars have analyzed the application of the Internet of Things in hospital information construction from several perspectives, but they have not proposed a clear proposed network security maintenance approach.This article mainly starts from the principle that information security depends on three-point technology and seven-point management and uses a combination of technology and management to study the maintenance of hospital information network security. Previous studies on hospital information network security were either carried out from a technical perspective or from a technical perspective. Simple management system discussion designed a set of hospital information network security maintenance evaluation methods and evaluation index system. It used it in the practice of evaluating the level of hospital information network security maintenance. In this paper, we discuss how to establish a set of appropriate evaluation index systems to conduct empirical research on the maintenance level of network security in hospital informatization construction so as to obtain the level of hospital information network security maintenance, find out the problems existing in hospital information network security maintenance, and analyze reasons and suggestions. It is conducive to optimizing workflow, sharing information resources, reducing work intensity, and improving work efficiency; it is conducive to in-depth management of details, standardizing work behavior, reducing medical errors, and improving work quality; it is conducive to driving modern management of the hospital and improving the external image of the hospital—the only way to sustainable development.


## 2. Maintenance of Network Security in Hospital Information Construction Based on the Internet of Things

### 2.1. Network Security and Protection in the Construction of Hospital Information

The Internet of Things is an extension of the Internet, with its ability to combine various information sensing devices with networks to form a vast network. The use of the Internet of Things involves identity confirmation and data collection, processing, and analysis, and these processes contain a large amount of patients’ personal privacy information. In most cases, patients are unwilling to disclose their privacy about their illnesses. Once the information is leaked, the criminals may use the information to do something that damages the legitimate rights and interests of the patients, which will bring bad influence to the reputation of the patients and even the hospital where they are located.


#### 2.1.1. The Importance of Network Security and Protection in the Construction of Hospital Informatization

Under the current background of social development and economic construction, if the hospital wants to improve management and service efficiency, strengthen the working connection between various departments and departments, and realize the information development of work, the most important thing is to integrate network information technology with the work of the hospital is combined [5]. With the support of the modern medical and health information system, the hospital’s various book information has achieved integrated development, and it has provided convenience for data sharing. After the hospital’s information is processed and shared, the work efficiency and quality of the relevant medical staff have been improved. At the same time, the work pressure of various departments can be reduced to a certain extent, and the work links and workflows can be simplified for the hospital’s medical staff to offer comfort [6, 7]. From a hospital system perspective, building cyber security can significantly reduce network-related errors and lower a range of costs. The Internet of Things in hospitals includes three aspects: “things” refer to medical-related objects, including doctors, nurses, patients, medical equipment, etc.; “connection” refers to information interaction; “network” refers to medical processes, which must be based on standards process. In the age of hospital informatization, it is not only necessary to connect various application software but also to connect patients, doctors, nurses, mobile devices, medical equipment, health care equipment, and various sensors. Various types of information are digitally collected, processed, stored, and shared to realize the intelligent medical treatment of people and intelligent management of objects. The network security and maintenance model of hospital information construction is shown in Figure 1.Figure 1
Network security and maintenance model of hospital information construction.


#### 2.1.2. The Status Quo of Network Security in Hospital Informatization Construction

The development of the hospital Internet of Things needs to ensure the security of information because the exposure of any information may bring serious harm to individuals or groups. First of all, both the perception layer and the network layer of the hospital contain a large amount of data information. When building the Internet of Things, the hospital should improve the information privacy security technology of each node in the perception layer and the network layer of the Internet of Things and gradually establish a hierarchical privacy protection mechanism with the IoT Security Framework.(1) System Security Issues. For the informatization construction of hospitals, the most basic and most critical one is the related operation and management system, which is also one of the important contents in the process of hospital informatization safety management [8, 9]. In the process of relevant practical work, if the system is not maintained and upgraded, then criminals will be given an opportunity. In order to seek their own personal gain, they will hire hackers or use virus software to attack the hospital’s network information system. Attacks to steal data in the information system pose a threat to the personal privacy of patients and medical workers [10, 11]. It can be seen that the key task of the hospital at this stage is to strengthen the construction of network information and the resolution of safety problems. The Internet of Things technology currently used by hospitals is relatively backward and hinders the development of the application of the Internet of Things. The hospital should strengthen the improvement of the Internet of Things technology, and the hospital can introduce more advanced technologies, such as RFID technology. Although the cost of RFID is much higher than that of barcode technology, RFID technology has the advantages of fast scanning, smaller size, anticontamination and durability, reusability, penetrating and barrier-free reading, and data memory. It has the characteristics of large capacity and better security, and RFID technology also has functions such as positioning and tracking so that the Internet of Things can be extended to various fields of the hospital.(2) Internal Factors. For a long time, the hospital has not paid much attention to the construction of network information, so the lack of professional network security maintenance personnel has prompted the hospital’s information construction to have more security network problems, and it is difficult to be developed, even if people are aware of the problem exist, but it cannot provide a better solution. At the same time, the level of network security education in the hospital is low, and the level of publicity on network security is not enough. The staff inside the hospital has not established a strong awareness of security risks, which also causes the hospital's information construction process to be prone to security risks [12, 13]. For example, some medical workers privately connect private collections and external devices such as USB flash drives to the hospital’s computer, laying a hidden safety hazard for the hospital’s informatization construction, giving the virus a chance to take advantage of it, and affecting the normal work of the hospital.(3) Equipment Factors. The most important thing is to maintain the relevant computer equipment. However, as far as the current informatization construction work of hospitals in our country is concerned, it is still in the initial stage of development. There is an insufficient experience in the use, inspection, and maintenance of equipment. Problem solving and maintenance are in a passive position. When network security problems occur, they cannot be actively discovered and solved, and can only be passively repaired, which is not conducive to the long-term safe and stable operation of the hospital [14, 15].


#### 2.1.3. Hospital Information Construction

The long-term development plan of the hospital information system and the reform of the health care system have potential demand for the hospital network, which should also be considered when choosing network technology [16]. Multimedia transmissions such as medical images have special requirements for hospital networks. High-speed local area networks must be used to transmit data to meet the requirements of data sharing and real-time access. Finally, the connection with the Internet should be considered. The Internet is a huge information database and communication network. We cannot ignore this huge information resource. However, from the perspective of network security, it is better to separate the internal and external networks [17, 18]. The network organization structure is shown in Figure 2.Figure 2
Internal network map.


#### 2.1.4. Infrastructure and Network Security

Pharmaceutical companies have clear network boundaries and strict network access mechanisms. Through the security gateway and VLAN technology, different operators, different attributions, different applications, different departments, etc., have carried out different levels of network isolation on the production network and office network of the WeDoctor Group. At the same time, relying on network isolation, a multilevel network access mechanism has been established and only authorized, legal, safe, and trustworthy accounts can access the corresponding network. The access to the production server needs to be controlled uniformly through the bastion host. In this process, the DMS console combines the control signals into one and then uses the network and the Internet to structure an interconnected channel of information for unified control. Through the above mechanism, the harm caused by hacker attacks on corporate security is further reduced, and the group business and data security are ensured. The infrastructure and network security architecture diagrams are shown in Figure3. In order to protect the privacy rights of patients in medical treatment, relevant departments should improve the laws and formulate special privacy protection regulations for electronic medical records and RFID technology. Only when safety is guaranteed are patients willing to accept the application of the Internet of Things and cooperate with treatment with peace of mind.Figure 3
Infrastructure and network security architecture diagram.The network security system is made up of a hardware network, communication software, and an operating system. For hospital systems, it uses physical equipment such as hardware circuits as a carrier, connected through the use of network equipment such as routers, hubs, switches, and network cables, and then hospital users can build the communication network they need.


### 2.2. Evaluation Index of the Degree of Network Security Hardware and Software Equipment

The calculation formula is as follows:(5)PBLDD=FDDFZX.In the formula,PBLDD represents the ratio of the stand-alone antivirus products, and FDD represents the cost of purchasing the stand-alone antivirus products.Network security filtering product deployment rate, the ratio of the hospital’s cost of purchasing network security filtering products to the total investment cost of information security equipment. The calculation formula is as follows:(6)PBLGL=FGLFZX.In the formula,PBLGL represents the provision rate of network security filtering products, and FGL represents the cost of purchasing network security filtering products [20].Virtual private network deployment rate, the ratio of the hospital's expenditure on purchasing a virtual private network to the total investment cost of information security equipment. The calculation formula is as follows:(7)PBLWP=FWPFZX.In the formula,PBLWP represents the virtual private network deployment rate, and FWP represents the cost of purchasing a virtual private network [21].According to some medical personnel, there are sometimes some problems in the process of using the Internet of Things: (1) The equipment responds slowly and the system is sometimes paralyzed. Since the patient’s diagnosis and treatment information must be retrieved and input through the equipment and system, once these problems occur, the work will not be carried out normally. At this time, it takes time to wait and system repair, which will reduce the work efficiency of medical staff and also subject to patient dissatisfaction. (2) The network signal is unstable. The use of IoT devices by medical staff is supported by wireless networks. If the signal is unstable, medical information may be incompletely recorded, which will cause certain security risks.

The calculation formula is as follows:(7)PBLWP=FWPFZX.In the formula,PBLWP represents the virtual private network deployment rate, and FWP represents the cost of purchasing a virtual private network [21].According to some medical personnel, there are sometimes some problems in the process of using the Internet of Things: (1) The equipment responds slowly and the system is sometimes paralyzed. Since the patient’s diagnosis and treatment information must be retrieved and input through the equipment and system, once these problems occur, the work will not be carried out normally. At this time, it takes time to wait and system repair, which will reduce the work efficiency of medical staff and also subject to patient dissatisfaction. (2) The network signal is unstable. The use of IoT devices by medical staff is supported by wireless networks. If the signal is unstable, medical information may be incompletely recorded, which will cause certain security risks.


## 3. Experimental Design of Network Security Maintenance in Hospital Information Construction

### 3.1. Test Subject

Taking 12 hospitals in this city as the test subjects, using the evaluation methods and evaluation indicators of hospital information network security maintenance to conduct an empirical analysis of the information security maintenance level of these 12 hospitals. The data analyzed are all from the questionnaires filled out by these 12 hospitals. To understand the situation and collect data from six aspects of hospital information network security risk assessment, strategy establishment, information security software, and hardware deployment level, information security staffing level, security awareness training, and auditing, and conduct empirical research. Through the analysis of data and information, a comprehensive evaluation result of the safety maintenance level of the information network of the hospitals in this city is obtained, and the direct cause of the low level of safety maintenance of the information network of the hospitals in this city is found. An interview outline was designed, and an interview was conducted with the leaders of an affiliated hospital in charge of hospital informatization management to understand the basic situation of the informatization construction of the sample hospitals, the application of the Internet of Things in informatization management, and the achievements and existing problems in the process of application.


### 3.2. Questionnaire

#### 3.2.1. Design of the Questionnaire

Part of the information and data in the hospital information network security governance evaluation system cannot be obtained directly from the hospital’s existing yearbooks and other statistical data. In order to facilitate the investigation and ensure the truthfulness and accuracy of the data and information, starting from the actual situation of the hospital, the items in the designed questionnaire can basically be found from the own data of these hospital network centers. Because in the evaluation of hospital information network security governance, some measurement standards are difficult to quantify, so part of the information collected in the questionnaire is textual information, and part of it is digital information. According to the actual situation of the hospital’s networked information construction, the data survey part only requires four years of data from 2017 to 2020 so that dynamic research and trend analysis of the development process of hospital information network security governance can be carried out. During the design process, the article designed a number of thematically relevant elements around information cyber security governance in accordance with the principle of rationality.


#### 3.2.2. How to Issue and Withdraw Questionnaires

The survey time is from November to December 2020. Part of the questionnaire was sent to each hospital network center by e-mail through the city’s main node network center, and each hospital network center also returned by e-mail; part of the questionnaire was completed in person by going to the hospital to investigate.


### 3.3. Establish Model Evaluation Index System

The evaluation index is a specific evaluation item determined according to some evaluation goals, which can reflect some basic characteristics of the evaluation object. The index is specific and measurable, and it is the observation point of the goal. Definite conclusions can be drawn through actual observation of the object. Generally speaking, the evaluation index system includes three levels of evaluation indexes: they are the relationship between gradual decomposition and refinement. Among them, the first-level evaluation indicators and the second-level evaluation indicators are relatively abstract and cannot be used as a direct basis for evaluation. The third-level evaluation indicators should be specific, measurable, and behavior-oriented and can be used as a direct basis for evaluation [22]. Based on these principles, the article establishes indicators such as deployment rates, staffing rates, and the number of safety training sessions.


### 3.4. Statistical Processing

Statistical analysis was performed with SPSS 13.0 statistical software. The significance test of the difference was performed by one-way analysis of variance, the difference between the two groups was tested by LSD-t, and the statistics of the maintenance level of network security in hospital information construction were performed by groupt-test.

## 4. Network Security Maintenance in Hospital Information Construction

### 4.1. Information Security Risk Analysis, Strategy Establishment, and Audit Status of the Investigated Hospital

Using qualitative methods, the hospital’s work in the three aspects of information security risk analysis, the establishment of information security-related strategies, and review of the information security process is divided into three levels: comprehensive, partial, and nondoing to conduct investigations and research the hospital. The work in these areas is attributed to three levels of proportions. The survey results are shown in Figure4.Figure 4
Information security risk analysis, strategy establishment, and audit status of the investigated hospital.It can be seen from Figure4 that in the formulation of information security backup strategies, 16.67% of hospitals have formulated complete strategies and systems, and the remaining 75% of hospitals have formulated partial strategies and systems. In the formulation of emergency response strategies, 41.67% of the hospitals have formulated perfect strategies and systems, 41.67% of the hospitals have formulated some strategies and systems, and 16.67% of the hospitals have not done this work at all. It can be seen from this data that hospitals still do not pay much attention to the risk assessment of network information security. During the investigation process, it was learned that some hospitals had no awareness of risk assessment because the network construction had just started; and most of them were due to the network. Due to construction funding issues, no suitable risk assessment tools have been purchased.


### 4.2. Information Security Software and Hardware Input of the Hospital under Investigation

#### 4.2.1. Information Security Equipment Single Item Deployment Rate in Hospitals

According to the evaluation methods and evaluation indicators of hospital information network security maintenance, the individual information security equipment provision rate, the comprehensive information security equipment provision rate, and the information security equipment provision improvement rate of the investigated hospitals are analyzed, respectively. The results are shown in Table1.Table 1
Information security equipment single item deployment rate of the hospital under investigation.

It is known that the rate will drop to 4.18% in 2020. The individual security equipment deployment rate of the surveyed hospitals is at a very low level from 2017 to 2020, and many schools have no network security products at all. With the further advancement of hospital informatization and network construction, hospitals will gradually invest in information security products starting in 2020, and the equipment of major information security products will occupy a certain proportion. The reason for this is that most hospitals fail to deploy security devices in a timely manner because they do not pay enough attention to network security issues.


#### 4.2.2. Comprehensive Provision Rate of Information Security Equipment in the Surveyed Hospital

From the evaluation methods and indicators of hospital information security, it can be known that the comprehensive provision rate of information security equipment in the hospital is equal to the ratio of the total investment cost of information security equipment to the total investment cost of the entire network construction and operation of the hospital.It can be seen from Table2 that, in general, hospitals’ investment in information security equipment is gradually increasing, but the equipment rate of information security equipment is still at a low level. Information security equipment investment only accounted for all network construction expenses in 2017 It’s 0.79% in 2018, 2.16% in 2018, 2.88% in 2019, and only 3.67% in 2020. Compared with some foreign hospitals, the gap is hundreds or even thousands of times, indicating that Chinese hospitals still need to increase investment in information security equipment to obtain a safe and reliable information network.Table 2
Comprehensive provision rate of information security equipment in surveyed hospitals.

### 4.3. Information Security Awareness Training of the Investigated Hospitals

The survey data of each hospital’s information security awareness training is divided into four levels according to the number of times held each year: 0 times, 1–3 times, 4–6 times, and more than 6 times. The research falls within the scope of each level. The proportion of hospitals in the entire surveyed hospitals and the results are shown in Figure5.Figure 5
Information security awareness training of the investigated hospital in 2020.It can be seen from Figure5 that the information security promotion activities carried out by the surveyed hospitals in 2020 show that only 8.33% of the hospitals have carried out more than 6 information safety promotion activities, 16.67% of the hospitals have carried out 4–6 times, 33.33% Of the hospitals did it 1–3 times, and 41.67% of the hospitals did not promote information security knowledge to teachers, students and staff at all. These data indicate that hospitals are not sufficiently aware of the importance of information security and not paying enough attention to information security education and publicity work. Judging from the information security awareness training level we have defined, the information security awareness training level evaluation of the surveyed hospitals in 2020 is almost at a poor or medium level.Based on the above, we find that the level of information security construction in hospitals varies, and many hospitals have not even started to build their own information security systems. The Internet of Things is an important grip for hospitals to carry out information security construction, so hospitals must vigorously develop information technology and seize the Internet of Things position in a timely manner.
