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.

In Virtual Private Network tunneling is designed to examine the performance of Private network for transferring the data. It implements and analysis the IP tunnel in Virtual Private Network (VPN). Tunneling is a method that is used to transfer the data or packet of one protocol using different network communication mediums of another protocol. This research is emphasized to examine the performance of Private network using tunneling for the transfer of data. Basically tunneling is used to send a packet, data or traffic of one protocol using an intermediate structure of another protocol. It is called as the process of encapsulation, transmission, over different types of secured networks as encapsulation and security is one of the procedure within this network provides security .This paper gives overview of a Virtual Private Network with IP Tunnel. Virtual private Network generates a secure encryption and decryption of data with the help of IP tunneling at end points. Basically VPN routes through the internet from a private network to transferring the data from one end (source) to other end (destination). With the help of tunneling and VPN user can check the working of different parameters under various applications.

VoIP (Voice over Internet) dikenal juga dengan sebutan IP (Internet Protocol) Telephony saat ini semakin banyak digunakan karena memiliki beberapa keunggulan, salah satu diantaranya yaitu tarif yang jauh lebih murah daripada tarif telepon tradisional sehinggapengguna telepon dapat memilih layanan tersebut sesuai dengan kebutuhannya. VoIP dapat mereduksi biaya percakapan sampai 70%. Selain memiliki beberapa keunggulan di atas,VoIP juga memiliki kelemahan yang sangat vital yaitu dari segi keamanan transfer suarakarena berbasis IP, sehingga siapapun bisa melakukan penyadapan dan perekaman terhadap data VoIP. Ganguan yang terjadi pada sistem VoIP ada berbagai macam diantaranya, transferdata yang lewat pada suatu jaringan seperti misalnya dapat disalahgunakan (abuse), dapatdibajak isi data tersebut (sniffing), dan tidak dapat mengakses server dikarenakan server yang kelebihan muatan (Denial of Services).Ada beberapa cara untuk mengamankan komunikasi data VoIP, antara lain, dengan mengamankan jalur yang digunakan pengguna untuk melakukan komunikasi VoIP denganmenggunakan metode VPN (Virtual Private Network) dan juga dapat dilakukan suatu metode kriptografi pada aplikasi VoIP tersebut sehingga data yang dikirimkan dapat dilindungidengan baik. VPN adalah teknik pengaman jaringan yang bekerja dengan cara membuat suatu tunnel sehingga jaringan yang dipercaya dapat menghubungkan jaringan yang ada diluar melalui internet. Titik akhir dari VPN adalah tersambungnya Virtual Channels (VCs)dengan cara pemisahan. Kenyataannya koneksi sebuah end-to-end VPN tergantung dari sebuah nilai dari hubungan daripada titik-titiknya. VPN mempunyai dua metode dalampengamanan yakni IPSec dan Crypto IP Encapsulation (CIPE). Selain itu dapat dipergunakan teknik Kriptografi (cryptography) yang merupakan ilmu dan seni penyimpanan pesan, data,atau informasi secara aman.Sistem VoIP menggunakan VPN ini diharapkan dapat memberikan keamanan transfer data pada jaringan internet maupun intranet.

The article is devoted to the study of evaluative tools used in modern French media in order to form the media image of a representative of the political elite. The techniques used in the creation of a memorial media portrait of Jacques Chirac (1932—2019), President of France from 1995 to 2007 are considered. The research material was the most prestigious French print media of various political orientations, published in late September — early October 2019 in connection with the death of the ex-President of the French Republic. The relevance of the research topic is dictated by the close attention of modern linguistics to axiological phenomena, differently presented in different types of discursive practices. The novelty of the study is due to the appeal to the analysis of the complex of evaluation tools used in the French print media when characterizing the former leader of the state during the nation’s farewell period. The estimated potential of the title of the article and its influence on the formation of the estimated vector of the entire text of the publication are shown. A systematic analysis of the assessment expression means, reflected in the memorial media portrait of the politician, is given. The factors that influenced the peculiarities of their use in this type of media portrait are revealed.

Akhir-akhir ini sudah mulai banyak perusahaan yang memanfaatkan protokol Virtual Private Network (VPN) sebagai media akses/komunikasi antar jaringan interlokal. VPN adalah sebuah protokol keamanan jaringan yang dapat digunakan sebagai salah satu cara untuk meningkatkan keamanan jaringan dari sisi transmisi data. Dengan pemanfaatan VPN, koneksi antar jaringan dapat terbentuk secara virtual walaupun tidak terbentuk secara fisik. Selain itu, dengan memanfaatkan protokol VPN, user (client) dapat mengkases Server secara private melalui jaringan public. Dengan demikian komunikasi antara Client dan Server terjaga dari Sniffing (penyadapan) dari pihak yang tidak bertanggung jawab. Akan tetap tingkat keamanan yang dihasilkan dari penerapan VPN ini perlu dilakukan pengkajian yang lebih dalam. Sehingga tingkat keamanannya dapat diketahui apakah sudah termasuk dalam kategori aman ataukah masih ada peluang bug yang membahayakan dari penetrasi. Dalam penelitian ini dilakukan pengujian Scanning dan Sniffing pada penerapan VPN menggunakan toos hacking yaitu Nmap dan Wireshark. Sedangkan pengujian performansi service pada VPN Server, dilakukan pengujian Denial of Service (DoS) menggunakan tools hacking yaitu LOIC. Adapun objek penelitian ini adalah perangkat Mikrotik RouterOS yang digunakan pada Universitas Teknokrat Indonesia. Hasil penelitian yang didapatkan bahwa komunikasi data antar jaringan (antara VPN Server dan VPN Client) dapat terenkripsi dengan baik. Akan tetapi dari segi konektifitas antar jaringan sangat dipengaruhi oleh performansi bandwidth yang digunakan oleh sistem jaringan tersebut. Selain itu berdasarkan hasil pengujian performansi service pada VPN Server didapatkan hasil bahwa service pada VPN Server dapat dimatikan pada request (ping) sebesar 1.899.276 request. Hal ini dipengaruhi oleh spesifikasi perangkat Mikrotik RouterOS yang digunakan. Adapun untuk penelitian selanjutnya perlu dilakukan pengujian performansi konektifitas menggunakan bandwith yang lebih besar dan untuk menguji performansi service VPN Server menggunakan spesifikasi perangkat Mikrotik yang lebih baik.

Background: Every organization generally uses a VPN service individually to leather the actual communication. Such communication is actually not allowed by organization monitoring network. But these institutes are not in a position to spend huge amount of funds on secure sockets layer to monitor traffic over their computer networks. Objective: Our work suggests simple technique to block or detect annoying VPN clients inside the network activities. This method does not requires the network to decrypt or even decode any network communication. Method: The proposed solution selects two machine learning techniques Feature Tree and K-means as classifiction techniques which work on time related features. First, the DNS mapping with the ordinary characteristic of the transmission control protocol / internet protocol computer network stack is identified and it is not to be considered as a normal traiffic flow if the domain name information is not available. The process also examines non-standard utilization of hyper text transfer protocol security and also conceal such communication from hyper text transfer protocol security dependent filters in firewall to detect as anomaly in largely. Results: we define the trafic flow as normal trafic flow and VPN traffic flow. These two flows are characterized by taking two machine learning techniques Feature Tree and K-means. We have executed each experment 4 times. As a result, eight types of regular traffics and eight types of VPN traffics were represented. Conclusion: Once trafic flow is identified, it is classified and studied by machine learning techniques. Using time related features, the traffic flow is defined as normal flow or VPN traffic flow.
