<p align="center"><strong>ABSTRACT</strong></p><p><em>The internet as a data transmission backbone has security threats in sending data. To overcome the security problem of every data communication that is done through a public network (public network), then a connection is needed that requires a connection between workstations running privately, so that only workstations that have access can connect, by using a virtual private network or VPN. The advantage of a VPN is that data sent over an encrypted VPN is quite safe and the secret is maintained even through the internet network because the data sent will go through the tunnel. Tunneling itself is a method for transferring data from one network to another by using a veiled internet network. Two protocols can be chosen in a VPN, namely Point to Point Tunneling Protocol (PPTP) and Layer 2 Tunneling Protocol (L2TP). However, the performance of each of these protocols is unknown yet. To find out the performance of the two protocols we need a test with a simulation method. Using a Mikrotik router and Wireshark application with Quality of Service (QoS) parameters consisting of Packet Loss, Delay, and Throughput on 2 clients connected to the mikrotik router and each client uses a different protocol. All clients will stream videos simultaneously to get a data packet capture. The test results will be grouped into four categories, namely bad, moderate, good and very good. It is expected that data will be able to show the quality of service of both protocols. so that it can be used as a reference in the selection of VPN protocol to be used.</em></p><p><strong><em>Keywords: </em></strong><em>Quality of Service, PPTP, L2TP</em></p><p align="center"><strong>ABSTRAK</strong></p><p><em>Internet sebagai backbone pengiriman data memiliki ancaman keamanan dalam pengiriman data.

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.

One of the ways to maintain and improve the quality of service and security on the network of an agency of the Barangin Sub-District Office, Sawahlunto City (Central) is to add a VPN feature. Administrators who always monitor the flow of traffic by accessing routers and access points to find out network conditions. There are times when the Administrator is on a public network, he or she cannot access routers and access point devices because the Public IP obtained is Dynamic (random). To solve this problem, it is done through the Network Development Life Cycle (NDLC) method by combining the L2TP and IPsec VPN protocol systems on Mikrotik. A Virtual Private Network (VPN) is a private and secure network using a public network such as the internet. One of the bases for securing VPN technology is Internet Protocol Security (IPSec). IPSec is a protocol used to secure datagram transmission on TCP/IP-based networks. This study aims to design and implement a VPN network system by utilizing a public network, where this system provides advanced security enhancements on the internet network using IPSec. The information/data sent will be confidential with an automatic encryption method through the L2TP tunnel method from the server to the branch/client computer and vice versa. The VPN is implemented using a layer 2 (L2TP) tunneling protocol using two Mikrotik routers. There are few changes to the computer network configuration to minimize costs and implementation time. Tests are carried out to implement security on the network using the command prompt, where the admin observes packet loss and delay parameters to determine the increase in security quality on the network.

INTISARIKinerja jaringan yang buruk tentu akan berdampak buruk pada kerugian bagi sebuah perusahaan atau instansi, ketika kinerja jaringan yang digunakan oleh perushaan berubah menjadi lambat, pasti sangat berpengaruh terhadap kinerja perusahaan itu sendiri, terlebih jika sebuah perusahaan selalu bergantung pada internet untuk kelancaran bisnisnya. Semakin banyaknya perusahaan perusahaan yang membutuhkan kinerja jaringan yang cepat dan aman maka untuk mengatasi hal tersebut, ada beberapa metode yang bisa digunakan seperti banyaknya pilihan metode VPN (Virtual Private Network).Teknologi VPN adalah suatu komunikasi dalam jaringan sendiri yang terpisah dari jaringan umum. Private network sendiri dianggap lebih efisien karena kecepatan transfer data yang lebih besar dari pada kecepatan transfer data pada jaringan Internet, selain itu masalah keamanan dianggap lebih bagus karena hanya bergerak dalam lingkup terbatas saja. Secara umum, VPN adalah sebuah proses dimana jaringan umum (public network atau internet) diamankan kemudian difungsikan menjadi sebuah jaringan privat (private network). Sebuah VPN tidak didefinisikan oleh rangkaian khusus atau router, tetapi didefinisikan oleh mekanisme keamanan dan prosedur-prosedur yang hanya mengijinkan penggunanya yang ditunjuk akses ke VPN dan informasi yang mengalir melaluiya.Masalah yang dihadapi saat ini yaitu ketika performa jaringan yang lambat akan berpengaruh pada kinerja perusahaan, untuk berhubungan antar kantor menggunakan internet dan email untuk mengirim data dan berkomunikasi maka dibutuhkan jaringan privat untuk memudahkan mengakses file terhadap suatu tempat yang berbeda lokasi. Namun dalam Pemilihan VPN yang akan digunakan memungkinkan kurang tepatnya pemilihan metode yang  digunakan dalam mengelola jaringan intranet untuk perusahaannya.Dari uraian diatas maka penulis melakukan analisis perbandingan sebuah teknik tunneling dengan menggunakan SSTP dan L2TP+IPSec.  SSTP dan L2TP+IPSec merupakan protokol jaringan yang dapat melindungi jaringan dari ancaman luar seperti konflik IP, MAC dan DHCP server jahat, serta membuat performa jaringan lebih baik, dengan metode penggunaan jalur tersendiri yang di lalui atau dilewati. Dari kedua metode  tersebut penulis melakukan perbandingan performa jaringan ketika di terapkan metode SSTP dan L2TP+IPSec sehingga mengetahui performa jaringan mana yang lebih bagus dan cocok digunakan sesuai dengan kebutuhan pengguna.Hasil dari penelitian ini diharapkan dapat membantu siapapun untuk menentukan metode tunneling VPN yang akan digunakan kelak dalam suatu jaringan. Sedangkan dari hasil penelitian bisa diambil kesimpulan bahwa L2TP+IPSec lebih baik dibanding SSTP, dinilai dari parameter QOS yang sudah diuji dan dibandingkan.Kata kunci: Tunneling, VPN, SSTP, L2TP, IPSec, Quality Of Service ABSTRACTPoor network performance will certainly have a bad impact on losses for a company or agency, when the network performance used by the company turns out to be slow, it must be very influential on the performance of the company itself, especially if a company always relies on the internet for the smooth running of its business. More and more companies need fast and secure network performance. To overcome this, there are several methods that can be used such as the choice of VPN (Virtual Private Network) methods.VPN technology is communication within one's own network that is separate from public networks. Private network itself is considered more efficient because the data transfer speed is greater than the data transfer speed on the Internet network, besides that security issues are considered better because it only moves in a limited scope. In general, VPN is a process in which a public network (public network or internet) is secured and then functioned as a private network. A VPN is not defined by a specific circuit or router, but is defined by security mechanisms and procedures that only allow their designated users access to the VPN and the information that flows through it.The problem currently faced is when slow network performance will affect company performance, to connect between offices using the internet and email to send data and communicate, then a private network is needed to facilitate accessing files to a different location. However, the selection of VPNs that will be used allows less precise selection of methods used in managing intranet networks for the company.From the description above, the authors conducted a comparative analysis of a tunneling technique using SSTP and L2TP + IPSec. SSTP and L2TP + IPSec are network protocols that can protect networks from external threats such as IP, MAC and DHCP server conflicts, and make network performance better, by using separate paths that are traversed or traversed. From these two methods, the writer makes a comparison of network performance when applied SSTP and L2TP + IPSec methods so that it knows which network performance is better and is suitable for user needs.The results of this study are expected to help anyone determine the VPN tunneling method that will be used later in a network. While the results of the study can be concluded that L2TP + IPSec is better than SSTP, judged by the QOS parameters that have been tested and compared.Keywords: Tunneling, VPN, SSTP, L2TP, IPSec, Quality Of Service

The world has changed a lot in the last couple of decades. Instead of simply dealing with local or regional concerns, many businesses now have to think about global markets and logistics. Many companies have facilities spread out across the country or around the world, and there is one thing that all of them need a way to maintain fast, secure and reliable communications wherever their offices are. Until fairly recently, this has meant the use of leased lines to maintain a wide area network (WAN). A WAN had obvious advantages over a public network like the Internet when it came to reliability, performance and security. But maintaining a WAN, particularly when using leased lines can become quite expensive and often rises in cost as the distance between the offices increases. As the popularity of the Internet grew, businesses turned to it as a means of extending their own networks. First came Intranets, which are password-protected sites designed for use only by company employees. Now, many companies are creating their own VPN (virtual private network) to accommodate the needs of remote employees and distant offices.

UNSTRUCTURED The Internet of Medical Things (IoMT) combines medical devices and applications connected to healthcare information technology systems using network technologies. With the flourishing adaptation rate of Internet-enabled medical devices in healthcare applications, we need to guarantee the security and privacy of electronic health records (EHRs) and communications among these IoMT devices, exposed web services, and the underlying infrastructure. This research is a proof-of-concept (PoC) study for implementing an integrated security solution with Spring Security and KeyCloak open-access platform (SSK) to safeguard microservice architecture application programming interfaces (APIs). Subsequently, we extended the security solution with a virtual private network (VPN), Bcrypt hash, API key, network firewall, and secure socket layer (SSL) to build up a digital infrastructure following the Norwegian data protection policies and General Data Protection Regulation (GDPR). In this study, we have not proposed any new security solution; however, we have focused on accomplishing a hybrid security solution based on the established frameworks (e.g., Spring Security) and open-access software product (e.g., Keycloak) to protect microservice APIs for a health eCoach system as a PoC study. This study describes the methodological, technical, and practical considerations to protect REST interfaces only and ensuring the privacy of data in the system. We validate our SSK security implementation by theoretical evaluation and experimental testing. In addition, we compare the test results with related studies qualitatively to determine the effectiveness of the hybrid security solution (SSK).

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.
