Abstract:

Security of Internet of things network is difficult to manage because Internet of things devices are heterogeneous and always deployed in remote places. Based on these features, attacks against Internet of things network like distributed denial-of-service and system intrusion are easier than traditional network. In order to enhance Internet of things network’s security, in this article we propose the concept of intrinsic security to establish a trusted and autonomy Internet of things network. Intrinsic security emphasizes that network itself must be trusted and security autonomous to address the security problems which are caused by remote and heterogeneous. Based on this thought, we designed the architecture of Trusted Autonomy Security System. Trusted Autonomy Security System maintains a LAN characterized by trusted and security autonomy, in which all Internet of things network gateways formed a decentralized autonomy system to evaluate if other gateways or Internet of things devices are secure. Compared to traditional Internet of things networks, this architecture uses trusted computing technique to build the basic of security, and makes Internet of things network available to manage security automatically. In addition, the decentralized architecture could reduce security risks caused by compromise of single node in Internet of things network. With these advantages, it can be expected that this novel idea will have more development in Internet of things scenarios with high security requirements.

Abstract:

Food security creates a complex issue for American interests. Within a constantly expanding operational environment, food security remains a vital lifeline both domestically and abroad. Current methods of mapping an area’s food system rely on ad-hoc assessments that produce skewed results and minimal metric analysis. Previous assessments methodologies failed to incorporate components of a food system that influences the overall stability of an area. The research conducted utilized the Systems Decision Process (SDP) to create a value hierarchy and model that provide an assessment for an areas food system. The findings from the research showcase that a food system relies on several variables such as infrastructure, dietary needs, and the national stability of a region. A more enhanced assessment model was developed that placed an overarching value to a food network that allows ground commanders to gain a holistic overview of the condition of an areas food system.

Abstract:

Abstract: There are variations within the network of the differential computing system's underlying IPv6 network. There are different blind zones for security detection. It is thoroughly investigated how the automatic data processing system differs from the underlying IPv6 network. An enhanced underlying IPv6 network security detection module design approach is suggested for the multicomputer system based on this concept. One gets the comprehensive module design plan. The new technologies like receiving thread domain, object forwarding domain, and file buffer are taken into account by the network security detection system. It can alleviate the challenges with security detection brought on by IPv6 network variations in the underlying computing system. Thus, IPv6 networks have a significantly lower number of blind zones.

Abstract:

The development of information technology is a new challenge for computer network security systems and the information contained in it, the level of awareness of the importance of network security systems is still very low. according to a survey conducted by Symantec, the desire to renew an existing security system within a year within a company has the result that only 13% of respondents consider changes to the security system to be important from a total of 3,300 companies worldwide as respondents. This lack of awareness results in the emergence of security holes that can be used by crackers to enter and disrupt the stability of the system. Every year cyber attacks increase significantly, so that every year there is a need to improve the security of the existing system. Based on that, a method is needed to periodically assess system and network security by using penetrarion testing methods to obtain any vulnerabilities that exist on the network and on a system so as to increase security and minimize theft or loss of important data. Testing is carried out by using internal network penetration testing method which tests using 5 types of attacks. From the results of the tests, each system has a security risk of 20-80%. From the results of these tests it can be concluded that each system has a security vulnerability that can be attacked.

Abstract:

Currently, the main network security mechanisms (such as firewall, intrusion detection, and vulnerability scanning) cannot prevent malicious attacks absolutely from the public network. Therefore, how to ensure the security of the information in the private network is a hot topic. In this paper, a network physical isolation system is designed based on private protocol, in which internal and external networks are physically isolated during the data transmission. Thereby, the security of network information is protected and the network security problems can be solved effectively through this isolation system. This isolation system can be applied in high security network environment such as government departments and business units, etc.

Abstract:

This article proposes a computer network security defense system model based on multisource big data, which makes the security of computer networks more complete because of the shortage of current computer network security defense systems. The current network security situation is analyzed, and the problems faced in the field of network security are pointed out; then, multisource big data is introduced, and the characteristics of the multisource big data model are analyzed. This article proposes an information system network security model, which formally describes the relationship between network behavior among nodes, security threats, network attacks, and defense capability of security devices in an information system. After that, a network security defense system measurement scheme is constructed based on hierarchical analysis, and quantitative indicators of defense effectiveness are defined in two dimensions: risk severity of security threats and defense response actions of security devices, which enables quantitative evaluation of the security defense system, and then identifies omissions and defects of the network security defense system. A defense system measurement and optimization system is designed based on the proposed network security system measurement and optimization scheme. The application analysis of the project is combined with the actual scenarios. Through the evaluation and optimization of the security defense system in the natural methods, it is proved that the network security defense system evaluation and optimization scheme proposed in this article has reasonableness and effectiveness in the actual application.

Abstract:

E-Commerce security issues can be grouped under the categories of system availability, data integrity, and data privacy. System availability means that all necessary components are available to support a given users transmission requirements. Data integrity means that all valid messages that are sent are received, messages are not altered in such as way as to make them invalid, and unauthorized messages are not introduced and transmitted over the network. Data privacy means that transmitted messages contain only 'need to know' information and are seen only by their intended audience. Enterprise network security is typically reactive, and relies heavily on host security. This approach creates complicated interactions between protocols and systems that can cause incorrect behavior and slow response to attacks. Network security at both the e-commerce and customer sites must be constantly reviewed and suitable countermeasures must be planned. The security of a site depends on the security of the internal systems and the security of external networks.

Abstract:

Software-Defined Networking (SDN), controlling underlying network devices (i.e., data plane) in a logically centralized manner, is now actively adopted in many real world networking environments. It is clear that a network administrator can easily understand and manage his networking environments with the help of SDN. In SDN, a network operating system (NOS), also known as an SDN controller, is the most critical component because it should be involved in all transactions for controlling network devices, and thus the security of NOS cannot be highly exaggerated. However, in spite of its importance, no previous works have thoroughly investigated the security of NOS. In this work, to address this problem, we present the NOSArmor, which integrates several security mechanisms, named as security building block (SBB), into a consolidated SDN controller. NOSArmor consists of eight SBBs and each of them addresses different security principles of network assets. For example, while role-based authorization focuses on securing confidentiality of internal storage from malicious applications, OpenFlow protocol verifier protects availability of core service in the controller from malformed control messages received from switches. In addition, NOSArmor shows competitive performance compared to existing other controllers (i.e., ONOS, Floodlight) with secureness of network assets.

Abstract:

It is eminent that the Internet is far from being secure. Insecure networks have caused organizations to lose lots of money as a result of data loss or data corruption, and even worse, some organizations have also lost their reputation hence reduce the client’s confidence. Therefore, this research focused on the development of an improved network security system using a firewall that can secure both the internal and external network of an organization. The system was developed using both packet filtering and proxy server architectures to prevent unauthorized connection or access to the organization server or resources thereby reducing the risk of attacks to the network and loss of organizational data. The system was implemented using PHP and python programming languages and the backend was developed using MySQL as the database server; HTML, CSS, and JavaScript for the frontend layout. The implementation of this firewall system includes a monitoring admin interface from where most activities within the private network can be monitored and also this system can prevent or deny the unauthorized request of services either by an intruder from an external network or personnel within the network. Based on the findings of this study, the developed system is recommended for any organization that depends on computer networks for the running of their daily activities.

Abstract:

Network topology is one of the major factors in defining the behavior of a network. In the present scenario, the demand for network security has increased due to an increase in the possibility of attacks by malicious users. In this paper, a blockchain-based system is suggested for securely discovering and storing networks. Techniques such as cloud-based storage systems are not efficient and are lacking in trust, privacy, security, and data control. The blockchain-based technique suggested in this paper is capable of resolving these challenges. Experiments were performed using Mininet, Cisco Packet Tracer, and Ethereum blockchain with the network inference algorithm. This algorithm is capable of inferring the network topology even when only partial information regarding the network is available. The results obtained clearly show that the network is resistant to malicious users and various external attacks, making the network robust.

In recent years, the emerged network worms and attacks have distributive characteristics, which can spread globally in a short time. Security management crossing network to co-defense network-wide attacks and improve the efficiency of security administration is urgently needed. This paper proposes a hierarchical distributed network security management system (HD-NSMS), which can centrally manage security across networks. First describes the system in macrostructure and microstructure; then discusses three key problems when building HD-NSMS: device model, alert mechanism, and emergency response mechanism; at last, it describes the implementation of HD-NSMS. The paper is valuable for implementing NSMS in that it derives from a practical network security management system (NSMS).

Abstract:

The modern car is a complicated system consisting of Electronic Control Units (ECUs) with engines, detectors and wired and wireless communication protocols, that communicate through different types of intra-car networks. The cyber-physical design relies on this ECU network that has been susceptible to several kinds of attacks using wireless, internal and external access. The internal network contains several security vulnerabilities that make it possible to launch attacks via buses and propagation over the entire ECU network, therefore anomaly detection technology, which represents the security protection, can efficiently reduce security threats. So, this paper proposes new Intrusion Detection System (IDS) using the Artificial Neural Network (ANN) to monitor the state of the car by information collected from internal buses and to achieve security, safety of the internal network The parameters building the ANN structure are trained CAN packet information to devise the fundamental statistical attribute of normal and attacking packets and in defense, extracted the related attribute to classify the attack. Experimental evaluation on Open Car Test-Bed and Network Experiments (OCTANE) show that the proposed IDS achieves acceptable performance in terms of intrusions detection. Results show its capability to detect attacks with false-positive rate of 1.7 %, false-negative rate 24.6 %, and average accuracy of 92.10 %.

Abstract:

Wireless sensor network (WSN) is a new type of wireless network. It has many advantages, but there are some problems. These problems make it easier for attackers to analyze network security holes and attack and destroy entire networks. This article designs a security wireless sensor network model. It can resist most known network attacks without significantly reducing the energy power of sensor nodes. First, we cluster the network organization to reduce energy consumption. It also protects the network based on the calculation of trust levels and the establishment of trust relationships between trusted nodes and operates the trust management system based on a centralized method, secondly, on the basis of LEACH agreement, draws lessons from the principle of biological immune system, optimizes the wireless sensor network, and further proposes a new immune system structure suitable for wireless sensor networks. The experimental results show that the wireless sensor network model designed in this paper solves the high-efficiency and energy-saving design task, and the trust management system has satisfactory results in defending against attacks.

Abstract:

In recent years, there has been an upward trend in the number of leaked secrets. Among them, secret-related computers or networks are connected to the Internet in violation of regulations, cross-use of mobile storage media, and poor security management of secret-related intranets, which are the main reasons for leaks. Therefore, it is of great significance to study the physical isolation and protection technology of classified information systems. Physical isolation is an important part of the protection of classified information systems, which cuts off the possibility of unauthorized outflow of information from the network environment. To achieve the physical isolation of the network environment and build a safe and reliable network, it is necessary to continuously improve the level of network construction and strengthen network management capabilities. At present, the realization of physical isolation technology mainly relies on security products such as firewall, intrusion detection, illegal outreach, host monitoring, and auditing. This study analyzes network security systems such as intrusion detection, network scanning, and firewall. Establishing a model based on network security vulnerabilities and making up for network security hidden dangers caused by holes are generally a passive security system. In a network, the leader of network behavior—human behavior—needs to be constrained according to the requirements of the security management system and monitoring. Accordingly, this study proposes a security monitoring system for computer information network involving classified computer. The system can analyze, monitor, manage, and process the network behavior of the terminal computer host in the local area network, to achieve the purpose of reducing security risks in the network system. Based on the evaluation value sequence, the initial prediction value sequence is obtained by sliding adaptive triple exponential smoothing method. The time-varying weighted Markov chain is used for error prediction, the initial prediction value is corrected, and the accuracy of security situation prediction is improved. According to the security protection requirements of secret-related information systems, a complete, safe, reliable, and controllable security protection system for secret-related information systems is constructed, and the existing security risks and loopholes in secret-related information systems are eliminated to the greatest extent possible. This enables the confidentiality, integrity, and availability of confidential data and information in the computer information system to be reliably protected.

Abstract:

The development in different communication systems as well as multimedia applications and services leads to high rate of Internet usage. However, transmission of information over such networks can be compromised and security breaches such as virus, denial of service, unauthorized access, and theft of proprietary information which may have devastating impact on the system may occur if adequate security measures are not employed. Consequently, building viable, effective, and safe network is one of the main technical challenges of information transmission in campus networks. Furthermore, it has been observed that, network threats and attacks exist from the lower layers of network traffic to the application layer; therefore, this paper proposes an effective multi-layer firewall system for augmenting the functionalities of other network security technologies due to the fact that, irrespective of the type of access control being employed, attacks are still bound to occur. The effectiveness of the proposed network architecture is demonstrated using Cisco Packet Tracer. The simulation results show that, implementation of the proposed topology is viable and offers reasonable degree of security at different network layers.

Abstract:

Abstract The increasingly complex network environment leads to more and more intense network attacks. Traditional firewall and intrusion detection technology cannot guarantee the network security of power information system, so network space situation awareness becomes the most important in the field of network security. Big data technology can be used to better understand the operation of the network, and different types of data for rapid analysis. Build a security situation awareness system framework that integrates data collection, data processing, data storage, data analysis and data presentation to filter out harmful data and ensure network security. In this paper, the basic concept and system framework of network security situational awareness are briefly introduced. Firstly, Flume and Kafka are used to obtain log or network attack information, and MapReduce and Storm technologies are used for batch or real-time analysis to achieve the perception of network security. Then, the analytic hierarchy process (AHP) is used to determine the index weight, extract the characteristics of the network situation, and complete the evaluation of the network security situation by analyzing and constructing the decision matrix. The system has the characteristics of high availability, scalability and easy deployment, which can better support the perception and prediction of various network security threats.

Abstract:

The development of information technology nowadays has become faster, and this makes network security become important. A huge increasing number of computers that are connected makes many gaps in a network. An administrator has an important role in protecting the security of the network. The problem comes when an administrator has human problems such as pain, negligence, and tiredness while needing rapid information when there is an intrusion on the network. This problem can be solved by adding a data traffic detection system known as Intrusion Detection System (IDS). IDS will be connected to Mail Gateway until that administrator can receive notifications such as alerts during an intrusion to the network anytime and anywhere. Snort as one of the network security systems should be developed as a security detection system and network security. A security intrusion prevention system or an Intrusion Prevented System (IPS). The author tries to do analysis and testing on the subjects above to produce a system capable of detecting the intruder in a network that is mobile and also makes it easy for administrators to open data anywhere and anytime using any device.

Abstract:

The current day networks are under deliberate, continuous and premeditated attacks such as Hacker attacks, DoS attacks, IP Address Spoofing, Phishing, Sniffer attacks etc. The Network Intrusion Detection Systems (NIDS) proved to be reliable in parrying most of the issues and challenges faced by the corporate network security systems. But, the NID systems fall short in providing a completely fool-proof network security environment. False negatives and false positives proved to be considerable bottle necks in securing the networks from the attacks. This paper deals with the introduction of a software approach for the packet pre-filtering to ease security threats and the introduction of Network Behavior Analysis to enhance the security of the network. The Network Behavior Analysis helps the system to ease the burdens to the network and security of the network by the false positives. The NIDS compares all the incoming packets with the pre-defined rules or signatures to find suspicious patterns. The pre-filtering approach used in this paper is a result of the observation that very rarely an incoming packet matches the signatures or the IDS rules. During the pre-filtering step, a small portion of the packet is compared against the predefined signatures for any suspicious patterns and the initial pre-filtering match is considered for a full match. For time efficiency, this strategy is compared to more optimistic schemes that allow reassignment of flows between threads, and evaluated using several network packet traces.
