Abstract (sommario):

In recent years, network developments and user growth have increased network security problems and techniques. The trend in network security is towards web-based networks, given Internet users' diverse origins, unpredictable persons are more likely to participate in malevolent activities. Security and privacy safeguards are implemented using many technologies. This paper proposes using a virtual private network (VPN) to secure particular communications across vast networks. VPNs restrict unauthorised connections, benefiting secured hosts. Through a VPN network, connections can be kept hidden and external connections prohibited. The influence of a virtual private network (VPN) on a standard network's performance is studied by producing and assessing CBR, HTTP, and FTP payloads. The evaluation used throughput and time delay as performance measures after analysis of the finding, deep learning (DL) can predict attacks. Because that learns attack patterns during training to effectively forecast attacks. To detect attacks, deep learning-based attack prevention model was created This method uses Nave Bayes and FFNN to enhace network performance. The results show that VPNs affect packet latency and performance differently depending on the data type. The FFNN algorithm detects intrusions with 98% accuracy.

Abstract (sommario):

Now-a-days the significance of security has been greater than before because of the fact that data has been accessed and transferred through public network. The data which has been transferred could be sniffed which may be a loss for us. When data is transferred in to public network we need confidentiality, integration and authentication. In this review paper we will discuss all these factors that keep our data safe enough. In order to provide this factor a site-to-site virtual private network has been designed which provide more security to data and made the public network into private network. The virtual private network hides the source and destination address as well as it also hides the internal network so that our network would be safe enough.

Abstract (sommario):

Aplikasi Sistem Informasi yang ada di SMK Labor Binaan FKIP UNRI telah dapat menunjang proses keputusan yang akurat. Aplikasi Sistem Informasi tersebut bisa di akses melalui internet secara private dengan teknologi VPN ( Virtual Private Network), tetapi penggunaannya belum bisa di pantau secara spesifik oleh administrator jaringan, sehiingga perlu untuk membangunkan suatu sistem traffic monitoring dengan menggunakan Simple Network Management Protocol (SNMP) dalam mengimplementasikan aplikasi untuk melakukan pengamatan penggunaan lalu lintas data internet dari parameter yang ada pada jaringan VPN (Virtual Private Network) berbasis web, yang menjadi salah satu solusi dalam menyelesaikan masalah yang ada. VPN (Virtual Private Network) merupakan suatu cara memanfaatkan jaringan public sebagai jaringan private secara aman melalui internet yang menggunakan perpaduan teknologi tunneling dan enkapsulasi. SNMP merupakan sebuah protokol yang didesain untuk memberikan kemampuan pengumpulan data manajemen perangkat jaringan dan pengkonfigurasian perangkat jaringan secara jarak jauh (remotely). Sistem operasi yang digunakan pada server administator adalah Linux Ubuntu 12.04. Linux Ubuntu merupakan distro linux yang stabil dan cukup handal. Dengan adanya aplikasi network traffic monitoring pada jaringan VPN dapat membantu pihak administrator untuk memantau lalu lintas data sehingga penggunaan internet lebih optimal.

Abstract (sommario):

Proxmox has a feature that can build a private network in it. Each host on a private network on Proxmox generally shares physical resources, including network connections using a virtual network, one of which is a VLAN. The Proxmox server supports Open VSwitch as a virtual switch. Open virtual switch, an alternative virtual switch quite popular among cloud developers, can be a solution for managing traffic between Virtual Machins and external communications. The method used in this study is the Network Development Life Cycle (NDLC). After applying the automation engine using Ansible, it overcame the problem, namely speeding up configuration and reducing human error or errors in configuring virtual networks. The automation system can speed up the virtual network management process compared to the manual method based on 5 (five) experiments, namely when the manufacturing operation has an average time of 08 minutes and 42 seconds faster. Whereas when the addition operation has an average faster time of 08 minutes 17 seconds. On the other hand, when the deletion operation has an average time of 42 seconds faster.

Abstract (sommario):

Pemanfaatan teknologi komunikasi dan informasi perlu diterapkan pada instansi yang saat ini masih menggunakan sistem manual dan mengharuskan administrator untuk mengakses router dan memantau traffic internet secara langsung pada server. Virtual private network bersifat private dimana pada dasarnya jaringan ini tidak ada secara fisik, namun hanya berupa jaringan virtual, sehingga tidak semua orang dapat mengaksesnya. Selain jaringan internet, virtual private network juga diperlukan oleh perusahaan sebagai jaringan pribadi dengan jalur khusus yang bersifat lebih aman untuk mengakses jaringan lokal perusahaan dan memantau traffic internet pada router perusahaan dari jarak jauh. Perancangan virtual private network ini dilakukan dengan metode point-to-point tunneling protocol. Setelah dilakukan perancangan dan implementasi dapat disimpulkan bahwa virtual private network memiliki sistem kerja mengenkripsi semua data yang berada di jaringan instansi atau perusahaan, sehingga jalur komunikasi dengan jaringan publik menjadi lebih aman dan pihak lain diluar administrator tidak dapat mengetahui informasi yang berada dalam jaringan perusahaan.

Abstract (sommario):

The key point of this paper is to assess and look over the top of the line network layer-based VPN (Virtual Private Network) protocols because data link layer is hardly ever found to be in use in organizations, the reason is because of its exceedingly high charge. Virtual Private Network (VPN) is commonly used in business situations to provide secure communication channels over public infrastructure such as Internet. Virtual Private Networks (VPNs) provide a secure encrypted communication between remote networks worldwide by using Internet Protocol (IP) tunnels and a shared medium like the Internet. The paper follows and sets standards for different types of protocols and techniques, the VPN (Virtual Private Network) architectural feature is made to deliver dependable and safe network that is not in line with regular networks that provide a higher trust and a higher secure channel between user and organization. The current study took place to summaries the usage of existing VPNs protocol and to show the strength of every VPN. Through different studies that have been made by other researchers as well as an extra focus on the state of art protocol, Wire guard. It is also worthy to mention that wire guard compared with other protocols such as IPsec and GRE. The studies show the WireGuard being a better choice in terms of other well-known procedures to inaugurate a secure and trusted VPN.

Abstract (sommario):

Every organization chooses a virtual private network (VPN) as their top option since it is a practical and secure solution. Through the use of a virtual private network, this study seeks to evaluate the network in SMK (VPN). The descriptive qualitative research used in this study was carried out at the lab of SMK Negeri 1 Ampek Angkek. Data were gathered through observation, interviews, and document analysis studies. The method of data analysis employed descriptive analysis. The results of this study indicate that the activity on the VPN network is better than the Non-VPN because the activities carried out in the VPN tunnel are not known by others. Users find it simpler to finish their daily agenda as a result.

Abstract (sommario):

The detection of unauthorized users can be problematic for techniques that are available at present if the nefarious actors are using identity hiding tools such as anonymising proxies or virtual private networks (VPNs). This work presents computational models to address the limitations currently experienced in detecting VPN traffic. A model to detect usage of VPNs was developed using a multi-layered perceptron neural network that was trained using flow statistics data found in the transmission control protocol (TCP) header of captured network packets. Validation testing showed that the presented models are capable of classifying network traffic in a binary manner as direct (originating directly from a user's own device) or indirect (makes use of identity and location hiding features of VPNs) with high degrees of accuracy. The experiments conducted to classify OpenVPN usage found that the neural network was able to correctly identify the VPN traffic with an overall accuracy of 93.71%. The further work done to classify Stunnel OpenVPN usage found that the Neural Network was able to correctly identify VPN traffic with an overall accuracy of 97.82% accuracy when using 10-fold cross validation. This final experiment also provided an observation of 3 different validation techniques and the different accuracy results obtained. These results demonstrate a significant advancement in the detection of unauthorised user access with evidence showing that there could be further advances for research in this field particularly in the application of business security where the detection of VPN usage is important to an organization.

Abstract Virtualization of physical network devices is a relatively new technology, that allows to improve the network organization and gives new possibilities for Software Defined Networking (SDN). Network virtualization is also commonly used for testing and debugging environments, before implementing new designs in production networks. Important aspect of network virtualization is selecting virtual platform and technology, that offer maximal performance with minimal physical resource utilization. This article presents a comparative analysis of performance of the virtual network created by the virtual CSR1000v and virtual machines running Windows 8.1 on two different virtual private cloud platforms: VMware vSphere 5.5 and Microsoft Hyper-V Server 2012 R2. In such prepared testbed we study the response time (delay) and throughput of virtual network devices.

Abstract (sommario):

Users interested to use the Internet from anywhere and at any time. For this purpose, the Internet Engineering Task Force proposed the concept of network mobility. But the IETF’s mobile Virtual Private Network does not support for real time applications. In this paper, the user’s communication between public networks and the private networks can be secured by using Virtual Private Network gateway. This secured user’s communication is based on Session Initiation Protocol and AES algorithm. The security impact is computed analytically and the performance is simulated. The signaling cost can also be reduced in this approach. Cryptographic mechanism like encryption and decryption is applied through the AES algorithm, so that the data transmitted through the VPN gateway is quality and secured.

Abstract (sommario):

In the paper, a new construction technique for virtual network (e.g., Virtual Private Network (VPN)) based on flow permutation algorithm is proposed. In existing methods for creating virtual networks, whereby virtual networks are constructed one by one in time and the new virtual network can use only the remaining resources, it could be non-optimal. Our approach treats all traffic flows simultaneously and is capable of balancing the network much better than other existing techniques. As we show, the proposed new construction technique work well, even in the condition of hard loaded networks operating on the edge of capacity, i.e., in situations when traditional techniques could cause unbalanced network and significant congestion problems. For huge number of traffic flows, heuristic algorithm, whose complexity rises linearly, is evaluated.

Abstract (sommario):

Several subjects in Computer science necessitate practical and realistic classes in addition to supporting the theoretical underpinning taught to the students. In various subjects’ practical exposure & skill is imperative to meet the industry requirements. However, educational establishments can't provide an out-and-out environment for every student to practice. Providing an appropriate Lab for apprentices that bestows desired exposure and feel of a real Network has been a challenging task for every educational establishment. Virtual Labs have been a major milestone and are effectively implemented in numerous colleges and universities throughout the world. In this article, the author is providing a complete setup and functionality of Implementing Virtual Private Networks using virtual Labs to reflect a more realistic and appropriate Networking environment for instructional and educational purposes. Fresh graduates or Diploma holders rarely have practical exposure and experience in deploying and implementing VPNs. Establishing a Virtual Private Network is a cumbersome job, and lack of practical exposure makes it even difficult for a fresher to establish one exclusively for the employer. The Author is providinga guideline for the users so that they can establish Virtual Private Networks using virtual machines. Hencepresenting an environment wherein students can have numerous deployments of VPNs with different features. The students gain the required exposure and develop an understanding of Virtual Private Networks meticulously and pragmatically.

Abstract (sommario):

The defence-in-depth (DiD) methodology is a defensive approach usually performed by network administrators to implement secure networks by layering and segmenting them. Typically, segmentation is implemented in the second layer using the standard virtual local area networks (VLANs) or private virtual local area networks (PVLANs). Although defence in depth is usually manageable in small networks, it is not easily scalable to larger environments. Software-defined networks (SDNs) are emerging technologies that can be very helpful when performing network segmentation in such environments. In this work, a corporate networking scenario using PVLANs is emulated in order to carry out a comparative performance analysis on defensive strategies regarding CPU and memory usage, communications delay, packet loss, and power consumption. To do so, a well-known PVLAN attack is executed using simulated attackers located within the corporate network. Then, two mitigation strategies are analysed and compared using the traditional approach involving access control lists (ACLs) and SDNs. The results show the operation of the two mitigation strategies under different network scenarios and demonstrate the better performance of the SDN approach in oversubscribed network designs.

Abstract (sommario):

Wireless networks are susceptible to many security problems since the wireless medium is open. Jammer (jamming attack) is the most important problems in wireless networks. It is denial-of-service attack in which attackers send malicious signals or messages on a channel that is intended for normal traffic by intentionally interfering with the network. One of the solutions is the development of tunneling technology as an attempt to secure communication networks. Virtual Private Network (VPN) tunneling technology when integrated with firewall would provide a suitable security. In this study, number of Jammers would interfere with the normal operation of the network resulting in performance degradation of network. These Jammers decrease throughput and increase delay and data dropped. The aim of this study is to improve the performance of Wireless Local Area Network (WLAN) by integrating Firewall with VPN in number of different Riverbed Modeler simulation scenarios which it is utilized in this study for video and data applications. Firewall is a technology employed to regulate the level of network connectivity. It can block unauthorized access from an external network to an internal network’s resources. In this study, the tunneling technology of VPN was integrated with firewall to improve the performance by increasing the throughput and decreasing delay and data dropped. The firewall would block any access to the server from the workstations and the VPN would filter the packets to allow a specific access to the specific server. The results showed that VPN when integrated with firewall increased the throughput from 1,350,000 to 1,500,000 bits/sec and decreased the delay from 0.0054 sec to 0.0047 sec and data dropped from 7,800 to 5,000 bits/sec so that this study proved that VPN incorporated with firewall provides a good throughput and delay improvement for wireless local area network.

Abstract (sommario):

Vehicle information system is the data center of vehicle communication networks, for the sake of connecting the IPv6 host through IPv4 network area, a virtual network device (VND) in Linux embedded System is designed and implemented as a mid-layer module between the real device driver and internet protocol stack. The VND can establish a virtual tunnel between the vehicle information device and agent server. Both vehicle information device and agent server can support IPv4 and IPv6.Through the virtual tunnel, the agent server picked up the IPv6 packet which was built in IPv4 UDP data area, and transmit the IPv6 packets to the IPv6 remote server. So it works like a VPN device. The hardware platform of the vehicle gateway is based on ARM9, and the software is based on ARM-Linux. The instruction of hardware and software are as well as put forward.

Abstract (sommario):

With the further development of Internet, VPN technology would provide high-quality and low-cost wide-area data network, and would be safer than the majority of corporate special network. Main purpose of VPN technology is to save communication expenses for enterprises, especially replace existing special lines of enterprises and reduce communication cost. With constant mergers and acquisitions of enterprises and the occurrence of new relationship between enterprises and employees, traditional corporate network mode faces challenges. One solution is to use virtual private network when constructing enterprise information environment. During network design, if only for simple point-to-point data transmission, making full use of transmission security is enough, security mechanisms such as encrypted tunnel, flows separating, packet authentication, user authentication, authorization system and access control etc have been taken to ensure the security. From perspective of engineering, comparison between the construction of corporate VPN and tunneling protocol that realizes VPN is made.
