This paper proposes a design for a network connected over public networks using Virtual Private Network (VPN) technique. The network consists of five sites; center server and four customer service sites, each site consists of a number of LANs depending on the user services requirements. This work aims to measure the effect of VPN on the performance of a network. Four approaches are implements: Network design without using VPN, network design using VPN with centralized servers, network design using VPN with distributed servers, and network design using server load balance.The OPNET and BOSON simulation results show higher response time for packet transmission due to effect of VPN tunneling. The concurrent activation of application execution is used as a solution to the delay problem of the initial timing period while the application proceeds. The results dealing with QoS are E-mail, FTP, voice services traffic and IP traffic dropped. The VPN Tunnels is in the range of (0.01 to 0.02) sec.; along with this simulator there are four VPN tunnels in the network. Also, a special server’s load balance is used to manage distribution of the server processing load across all other network servers to achieve the best response

STMIK Bumigora Mataram strives to develop a curriculum that adopts the needs of the industrial world. In the past 2 years, Network Management lecturers have experienced problems related to practicum implementation. During this time the learning process uses virtualization installed on each laboratory computer. However, the system has various weaknesses, especially related to the freedom of access and availability. The implementation of Private Cloud Computing based on Proxmox Virtual Environment (PVE) which in the cluster can be a solution to the problems faced. PVE cluster which is made using four servers and integrated with one storage server can be used as a learning media for network management practicum and support high availability so that live migration can be done. Users can manage Virtual Private Servers using Linux Container (LXC) independently with a login and limited access permission account and the configuration can be done through the console and SSH. All practicum materials were successfully tested on LXC. An FTP-based local repository built on a storage server can minimize the bandwidth usage of an Internet connection and speed up the package installation. In addition port forwarding on the gateway router can facilitate the remote access needs on LXC from the Internet.

Healthcare applications store private user data on cloud servers and perform computation operations that support several patient diagnoses. Growing cyber-attacks on hospital systems result in user data being held at ransom. Furthermore, mathematical operations on data stored in the Cloud are exposed to untrusted external entities that sell private data for financial gain. In this paper, we propose a privacy-preserving scheme using homomorphic encryption to secure medical plaintext data from being accessed by attackers. Secret sharing distributes computations to several virtual nodes on the edge and masks all arithmetic operations, preventing untrusted cloud servers from learning the tasks performed on the encrypted patient data. Virtual edge nodes benefit from cloud computing resources to accomplish computing-intensive mathematical functions and reduce latency in device–edge node data transmission. A comparative analysis with existing studies demonstrates that homomorphically encrypted data stored at the edge preserves data privacy and integrity. Furthermore, secret sharing-based multi-node computation using virtual nodes ensures data confidentiality from untrusted cloud networks.

Virtualization technology has been applied to universities with computer study programs to support practicum in Network Management courses. Each user gets a Virtual Private Server (VPS) with container technology. VPS system that is prepared manually requires a long time, especially when the number of users is increasing. The activity repeats every semester so it becomes ineffective and inefficient. Application of automation using Ansible can help to manage VPS objects in the Promox Virtual Environment (PVE) Cluster dynamically. Network Development Life Cycle (NDLC) was used as a method in this study. The design of the VPS management automation system created supports the grouping of container, user and permission resource management for users. The design is implemented in Ansible Playbook. The test results show the average time of making VPS objects per student with an automation system 2 (two) times faster, that is 26.25 seconds compared to the old system which takes 2 minutes 15 seconds. Besides that, the Playbook that was created succeeded in automating the start and stop containers per group of students based on the practicum schedule dynamically so as to maintain the availability of services from the PVE Cluster.

The processing needs for the High Luminosity (HL) upgrade for the LHC require the CMS collaboration to harness the computational power available on non-CMS resources, such as High-Performance Computing centers (HPCs). These sites often limit the external network connectivity of their computational nodes. In this paper we describe a strategy in which all network connections of CMS jobs inside a facility are routed to a single point of external network connectivity using a Virtual Private Network (VPN) server by creating virtual network interfaces in the computational nodes. We show that when the computational nodes and the host running the VPN server have the namespaces capability enabled, the setup can run entirely on user space with no other root permissions required. The VPN server host may be a privileged node inside the facility configured for outside network access, or an external service that the nodes are allowed to contact. When namespaces are not enabled at the client side, then the setup falls back to using a SOCKS server instead of virtual network interfaces. We demonstrate the strategy by executing CMS Monte Carlo production requests on opportunistic non-CMS resources at the University of Notre Dame. For these jobs, cvmfs support is tested via fusermount (cvmfsexec), and the native fuse module.

The need to access data remotely is a person's need to be more efficient in doing a job. Currently there are many remote access application programs, one of which is TeamViewer by utilizing the internet public network. By installing a TeamViewer program on a client and server computer someone can do data work and repair remotely as long as it is connected to the internet. To be able to do remote access, of course, a client must already know the user and password from the server computer. The disadvantage of TeamViewer is that other people will easily remote access data simply by entering the user and password that the computer has on the server. To overcome this problem, VPN technology is used with the PPTP protocol where only the IP address of the client that has been registered on the proxy device can access data on the server. VPN allows clients to connect to the server privately through public networks. To find out the performance of the VPN network that is built, QoS (Quality of Service) parameter analysis is needed which includes delay, jitter, throughput and packet loss. From the results of the tests carried out, the results of QOS with an index of 3.75, which if converted to the standard TIPHON, VPN network at STMIK STIKOM Indonesia has a satisfactory quality.

Cloud based systems saves data off multiple organizations on shared hardware systems. Data segregation is done by encrypting data of users, but encryption is not complete solution. We can do segregate data by creating virtual partitions of data for saving and allowing user to access data in his partition only.

Full textAbstract:
Network function virtualization (NFV) is a new way to provide services to users in a network. Different from dedicated hardware that realizes the network functions for an IoT application, the network function of an NFV network is executed on general servers, and in order to achieve complete network functions, service function chaining (SFC) chains virtual network functions to work together to support an IoT application. In this paper, we focus on a main challenge in this domain, i.e., resource efficient provisioning for social IoT application oriented SFC requests. We propose an online SFC deployment algorithm based on the layered strategies of physical networks and an evaluation of physical network nodes, which can efficiently reduce bandwidth resource consumption (OSFCD-LSEM) and support the security and privacy of social IoT applications. The results of our simulation show that our proposed algorithm improves the bandwidth carrying rate, time efficiency, and acceptance rate by 50%, 60%, and 15%, respectively.

Pertumbuhan, perkembangan, dan kebutuhan akan informasi terus-menerus menjadi sebuah kebutuhan primer bagi setiap masyarakat umum, organisasi, perusahaan, dan lembaga pendidikan. Salah satu contoh lembaga pendidikan yang memiliki kebutuhan akan informasi yaitu Politeknik Negeri Sriwijaya (Polsri), dimana dosen dan mahasiswa memerlukan koneksi melalui sebuah media kabel ataupun nirkabel untuk terhubung ke jaringan internet (global) maupun jaringan intranet (lokal). Sistem Akademik dan Learning Management System (LMS) adalah salah satu jaringan lokal Polsri yang paling sering diakses untuk memenuhi kegiatan akademik. Dosen ataupun mahasiswa sebagai client akan terus dapat mengakses jaringan lokal tersebut selama jalur komunikasi atau media transmisi antar router client dan router server tetap terhubung. Apabila jalur komunikasi utama antar router client dan router server terputus oleh faktor tertentu, maka client tidak dapat mengakses jaringan lokal sehingga proses kegiatan akademik menjadi terhambat. Untuk menghindari kejadian tersebut, maka diperlukan sebuah jalur komunikasi cadangan (backup link) dan suatu penerapan teknik failover pada sisi router client. Teknik failover adalah teknik yang memiliki kemampuan untuk mengalihkan jalur komunikasi utama ke jalur komunikasi cadangan sehingga komunikasi dapat terus berjalan meskipun jalur komunikasi utama terputus. Jalur komunikasi cadangan pada implementasi ini didukung oleh teknologi telepon seluler generasi keempat atau teknologi yang lebih dikenal dengan istilah 4G LTE (Fourth Generation Long Term Evolution). Selain itu, terdapat penerapan Virtual Private Network (VPN) tipe Layer Two Tunneling Protocol (L2TP) pada jalur komunikasi cadangan untuk menjaga keamanan komunikasi. Protokol routing yang akan digunakan untuk melakukan proses pertukaran informasi routing pada implementasi ini adalah Border Gateway Protocol (BGP).

Full textAbstract:
Virtual Private Network (VPN) is a private network that uses public network to tunnel the connection from the users’ end to the VPN server. VPN allows users to create a secure connection to another network over the public Internet. VPNs can be used to shield users’ browsing activity and encrypts data transmitted over the network to prevent sniffing attack. Nowadays, users can either pay a premium price for a good VPN service or risk their privacy using free browser-based VPN. Thus, SafeSearch is developed to address these issues in mind. With SafeSearch, users will not need to fork out a lot of money for premium VPN subscription services or expose themselves to targeted advertising when utilising free browser-based VPN. In this study, open VPN protocol was used to create the VPN server on a microcomputer called Raspberry Pi. The software used was mostly open-source except for the VPN client. Obfuscation technique was used to hide VPN traffic by disguising it as just another normal Internet traffic against Deep Packet Inspection when passing through firewall. After the VPN server was established, tests were carried out to evaluate the functionality and reliability of the VPN server in “real-world” environment. The tests conducted were network restriction penetration assessment, network performance and user acceptance test. Penetration assessment result showed that SafeSearch is capable of bypassing web filtering and deep packet inspection. Network performance during SafeSearch connection has slight latency and bandwidth decline, although it is not overly affected. The outcome of the user acceptance test was positive as the majority of participants of the study were confident that SafeSearch can secure their connection and protect their privacy when browsing the web. To conclude, both objectives of this project were fully achieved and the scope of study was followed thoroughly.

Abstrak Meningkatnya permintaan pembaharuan aplikasi berbasis open source karena seiring meningkatnya jumlah pengguna sistem operasi Linux, oleh karenanya ketika banyak pengguna linux yang melakukan permintaan pembaharuan aplikasi menyebabkan lambatnya kecepatan unduh dan membutuhkan waktu lama. Salah satu solusinya yaitu dengan membuat mirror repository linux agar memudahkan dan menawarkan koneksi pengguna yang lebih baik. Namun demikian, suatu saat ketika semakin bertambah jumlah pengguna mirror tersebut akan mengalami penurunan kualitas download hingga dapat mengalami down, sehingga tidak dapat melayani permintaan pembaharuan pengguna dengan baik. Penelitian ini bertujuan untuk merancang dan membangun Mirror Repository Linux dengan menggunakan Load-balanced Mirror Service System (LMSS) dengan mengintegrasikan beberapa MIrror Server yang dibangun secara generate melalui Manage Large Network (MLN), dengan pembagian beban menggunakan Linux Virtual Server (LVS) pada metode Network Address Translation (NAT). Sehingga beban permintaan dari client dapat ditangani Mirror Server secara bersama – sama. Dengan demikian, rata – rata waktu download dapat berkurang sebanyak 17,2 % daripada menggunakan Single Server.AbstractThe increasing demand for open source-based application updates is due to the increasing number of users of Linux operating systems, therefore when many Linux users who request an application update cause slow download speed and takes a long time. One solution is to create Mirror Repository Linux in order to facilitate and offer better user connections. However, a time when the number of mirror users will decrease the quality of download until it can down, so it can not serve user renewal request well. This research aims to design and build linux mirror repositories by using Load-balanced Mirror Service System (LMSS) by integrating multiple Mirror Server generated via Manage Large Network (MLN), with load sharing using Linux Virtual Server (LVS) Network Address Translation (NAT). LMSS there is a Director Server as a counter / load manager that passes on the server, which will be forwarded to the destination server. So that the request load from the client can be handled Mirror Server together. Thus, the average download time can be reduced by 17.2% rather than using a single server.

<p>Open loop shaped control system is a form of system control without any feedback from the system. One example is the on-off condition which functions to connect and disconnect electricity. The condition to be studied is a dc motor that can be set to live and die via internet server-based client service. The server in this system is a virtual private server (VPS) device that will provide a source of service to the client in the form of a collection of information on dc motor conditions. In addition, its function is also to record the working time of the dc motor. So that a schedule can be determined when the dc motor is maintained. While the client is a control unit consisting of a microcontroller device, an ethernet module enc28j60 and a dc motor. In general the working principle of the system is beginning with the user accessing the desired VPS IP address through a web browser application. From the web browser the user chooses a dc motor to be activated. But before the client has been connected to the VPS regularly (every second), the point is to always get the latest dc motor condition information. Then the microcontroller will set the dc motor in active or off condition. The research method used is research and development. The results obtained from this study are that the amount of bandwidth needed for communication between VPS and microcontrollers via the internet network, when the control unit works is 6.02 kbps, while the response time for dc motor is 3.16 seconds and the response time for dc motor 2 is 3.46 seconds.</p>

Computer networks have become an important point in companies that have many branch offices to coordinate the transfer of data. PT Indo Matra Lestari's connection uses a VPN system using the PPTP method. Data Center is used as a VPN server, the client is the Head Office and Citereup Branch Offices. Between the Head Office and the Citereup Branch Office there is no direct connection so access to data made between the Head Office and the Citereup Branch Office is slow, because the data must pass through the Data Center before reaching its destination. Moreover, the data accessed is private to the company and only accessed on the local network. The solution used to create a direct and secure network path between the Head Office and Branch Offices is to use the EoIP Tunnel on the proxy router. Tunneling method in EoIP can make network bridging between proxy devices, EoIP Tunnel will change to Virtual Interface on the proxy router so that it is as if the proxy router is connected locally. Tunnel ID on the EoIP Tunnel functions as a tunneling path security. The application of the EoIP Tunnel makes the point to point connection point between Mikrotik devices faster in data access because the data access is directed to the destination. In order for this EoIP Tunnel connection to run optimally and well, a network management is needed in managing internet bandwidth usage

Blockchains can be used to build multi-player online games and virtual worlds that require no central server. This concept is pioneered by Huntercoin, but it leads to large growth of the blockchain and heavy resource requirements. In this paper, we present a new protocol inspired by payment channels and sidechains that allows for trustless off-chain interactions of players in private turn-based games. They are usually performed without requiring space in the public blockchain, but if a dispute arises, the public network can be used to resolve the conflict. We also analyze the resulting security guarantees and describe possible extensions to games with shared turns and for near real-time interaction. Our proposed concept can be used to scale Huntercoin to very large or even infinite worlds and to enable almost real-time interactions between players.

With the emergence of the fog computing and the sensor-cloud computing paradigms, end users can retrieve the desired sensory data generated by any wireless sensor network (WSN) in a fog-based sensor-cloud system transparently. However, the fog nodes and the cloud servers may suffer from many kinds of attacks on the Internet and become semitrusted, which threatens the security of query processing in the system. In this paper, we investigated the problem of secure, fine-grained spatial-temporal Top- k query in fog-based mobile sensor-cloud systems (FMSCSs) and proposed a novel scheme named STQ-SCS to tackle the problem based on the virtual grid construction and the size-order encryption-binding techniques. STQ-SCS can preserve the privacy of the sensed data items and their scores and make end users verify the completeness of the query results of fine-grained spatial-temporal Top- k queries with a 100% successful rate even if the fog nodes and the cloud servers are not totally trustworthy. Besides the good security performance, simulation results indicate that STQ-SCS is also an efficient scheme that incurs a much lower communication cost than the state-of-the-art schemes on securing fine-grained spatial-temporal Top- k query in FMSCSs.

Full textAbstract:
The advantage of using the Network Address Translation device is that the internal IP address, which makes the IP address space of Internet of Things (IoT) devices expanded, is invisible from the outside and safe from external attacks. However, the use of these private IPv4 addresses poses traversal problems, especially for the mobile IoTs to operate peer-to-peer applications. An alternative solution is to use IPv6 technologies for future IoT devices. However, IPv6 package, including IPSec, is too complex to apply to the IoT device because it is a technology developed for the user terminal with enough computing power. This paper proposes a gatekeeper to enable the real IP addresses of IoTs inside the same subnetwork to be not explicitly addressable and visible from outside of the gatekeeper. Each IoT device publishes its virtual IP address via the Registrar Server or Domain Name System (DNS) with which the gatekeeper shares the address mapping information. While the gatekeeper maintains the mapping information for the local IoT devices, the registration server or DNS has global address mapping information so that any peer can reach the mapping information. All incoming and outgoing packets must pass through the gatekeeper responsible for the address conversion and security checks for them from the entrance. This paper aims to apply our gatekeeper system to a platform of self-driving cars that allows surrounding IoT cameras and autonomous vehicles to communicate with each other securely, safely, and rapidly. So, this paper finally analyzes improvement effects on latency to show that our gatekeeper system guarantees the latency goal of 20 ms under the environment of 5G links.

The company’s satellite offices can get access to the server’s database through a virtual private network. With this arrangement, investment cost will increase rapidly if the company is going to equip GIS software to workstation of every related staff. To avoid this investment burden problem, a WebGIS system has been developed based on ASP.NET framework of Microsoft, as well as the open source products Geoserver, and OpenLayers. With this webGIS, the company staff can access to drainage database from everywhere through the Internet by using just a normal web browser making requests for data through a standard web page. They can also carry out several basic GIS functions, such as viewing, querying, and doing statistics and making graph. The system has been tested and proved to work effectively enabling the company staff to cost-effectively exploit its drainage Geodatabase through the internet.

In recent times, secure communication protocols over web such as HTTPS (Hypertext Transfer Protocol Secure) are being widely used instead of plain web communication protocols like HTTP (Hypertext Transfer Protocol). HTTPS provides end-to-end encryption between the user and service. Nowadays, organizations use network firewalls and/or intrusion detection and prevention systems (IDPS) to analyze the network traffic to detect and protect against attacks and vulnerabilities. Depending on the size of organization, these devices may differ in their capabilities. Simple network intrusion detection system (NIDS) and firewalls generally have no feature to inspect HTTPS or encrypted traffic, so they rely on unencrypted traffic to manage the encrypted payload of the network. Recent and powerful next-generation firewalls have Secure Sockets Layer (SSL) inspection feature which are expensive and may not be suitable for every organizations. A virtual private network (VPN) is a service which hides real traffic by creating SSL-protected channel between the user and server. Every Internet activity is then performed under the established SSL tunnel. The user inside the network with malicious intent or to hide his activity from the network security administration of the organization may use VPN services. Any VPN service may be used by users to bypass the filters or signatures applied on network security devices. These services may be the source of new virus or worm injected inside the network or a gateway to facilitate information leakage. In this paper, we have proposed a novel approach to detect VPN activity inside the network. The proposed system analyzes the communication between user and the server to analyze and extract features from network, transport, and application layer which are not encrypted and classify the incoming traffic as malicious, i.e., VPN traffic or standard traffic. Network traffic is analyzed and classified using DNS (Domain Name System) packets and HTTPS- (Hypertext Transfer Protocol Secure-) based traffic. Once traffic is classified, the connection based on the server’s IP, TCP port connected, domain name, and server name inside the HTTPS connection is analyzed. This helps in verifying legitimate connection and flags the VPN-based traffic. We worked on top five freely available VPN services and analyzed their traffic patterns; the results show successful detection of the VPN activity performed by the user. We analyzed the activity of five users, using some sort of VPN service in their Internet activity, inside the network. Out of total 729 connections made by different users, 329 connections were classified as legitimate activity, marking 400 remaining connections as VPN-based connections. The proposed system is lightweight enough to keep minimal overhead, both in network and resource utilization and requires no specialized hardware.

Cloud-based video surveillance systems, as a new cloud computing service model, are an emerging research topic, both at home and abroad. Current research is mainly focused on exploring applications of the system. This paper proposes a design and implementation method for cloud-based video surveillance systems using the characteristics of cloud computing, such as parallel computing, large storage space, and easy expandability. The system architecture and function modules are built, and a prototype cloud-based video surveillance system is established in a campus network using key technologies, including virtual machine task access control, video-data distributed storage, and database-active communicationmethods. Using the system, the user is able to place a webcam in a location that requires monitoring so that video surveillance can be achieved, and video data can be viewed through a browser. The system has the following advantages: low investment and maintenance cost, high portability, easily extendable, superior data security, and excellent sharing. As a private cloud server in the campus network, the system is able to not only provide convenient video surveillance services, but it can also be an excellent practical experimental platform for cloud computing-related research, which carries outstanding application value.

As all the entities are connected with each other, it generates load of data, which lacks proper security and privacy standards. Cryptography is one of the domains of Network Security, which is one such mechanism that helps the data transmission process to be secure enough over the wireless or wired channel and along with that, it provides authenticity, confidentiality, integrity of data and prevents repudiation. In this paper, we have proposed an alternate enhanced cryptographic solution combing the characteristic of symmetric, asymmetric encryption algorithms and Public Key Server. Here, the key pairs of end points (User’s Device and IoT device) are generated using Elliptic Curve Cryptography and the respective public keys are registered in Public Key Server along with their unique MAC address. Thereafter, both the ends will agree on one common private secret key, which will be the base for further cryptographic process using AES algorithm. This model can be called as multi-phase protection mechanism. It will make the process of data transmission secure enough that no intermediate can tamper the data.</span></p></div></div></div></div>
