This acquisition was not community has different attitudes towards GitHub is the idea without controversy, as it is well-known that the free software communities includes not only the ability to use software freely, of ‘forking’ so far, as it it is considered as a danger to FLOSS but also the libre nature in Open Source Software. In this study, development [10]. our aim is to explore these perceptions in FLOSS developers. We In this paper, we report on how external events such as conducted a survey that covered traditional FLOSS source Linux, acquisition of the open source platform by a closed source and BSD communities and received 246 developer responses. organization triggers a FLOSS developers such the Linux/ The results of the survey conﬁrm that the free community did trigger some communities to move away from GitHub and raised BSD Free Software communities. discussions into free and open software on the GitHub platform.

Bab 1 Pendahuluan
BAB 1 PENDAHULUAN 1.1 Latar Belakang Network Function Virtualization atau biasa yang disebut NFV merupakan sebuah konsep baru dalam mendesain, menyebarkan, dan mengelola sebuah layanan jaringan dengan cara pembuatan virtual sebuah perangkat jaringan dari yang sebelumnya berbentuk fisik atau perangkat keras sehingga dapat dipakai dan dipindahkan di berbagai lokasi jaringan yang diperlukan tanpa harus melakukan pemasangan alat baru. NFV memungkinkan beberapa perangkat jaringan dapat berjalan pada satu komputer. Perangkat – perangkat jaringan yang divirtualkan pada NFV disebut sebagai VNF (Virtual Network Function). Untuk menjalankan VNF dibutuhkan sebuah hypervisor yang mengatur manajemen hardware yang digunakan. Hypervisor atau yang dikenal sebagai virtual machine management dibagi menjadi 2 tipe, yaitu bare-metal hypervisor dan hosted hypervisor. Bare-metal hypevisor dapat berjalan langsung pada perangkat keras komputer sedangkan hosted hypervisor memerlukan operating system environment (OSE) untuk menjalankannya [1]. Salah satu contoh bare- metal hypervisor adalah XEN. Xen ProjectTM adalah platform virtualisasi open source yang mendukung beberapa cloud terbesar dalam produksi saat ini. Amazon Web Services, Aliyun, Rackspace Cloud Umum, Verizon Cloud dan banyak layanan hosting menggunakan software Xen [2]. Salah satu contoh VNF adalah virtual firewall. Kelebihan virtual firewall dibandingkan firewall fisik adalah mudah dikelola, dapat dipakai sesuai kebutuhan, dan efektivitas biaya [3]. Pada tugas akhir ini virtual firewall yang digunakan adalah OPNsense, pfSense, dan IPFire karena ketiga firewall tersebut bisa didapatkan secara gratis dan bersifat open source serta ketiga firewall tersebut dapat dikonfigurasi melalui web. pfSense merupakan firewall berbasis FreeBSD yang sangat populer untuk solusi keamanan serta user dapat melakukan modifikasi dan mudah dalam instalasi [4]. IPFire adalah sebuah distribusi Linux yang berfokus pada setup yang mudah, penanganan yang yang baik, dan tingkat keamanan yang tinggi [5].

Vyos Platform | DATASHEET HOW YOU CAN USE Vyos
VyOS Platform the power of your environment VyOS is a network operating system which supports most of modern routing protocols and network security features. VyOS runs equally well on bare metal hardware and inside virtual machines, including common cloud platforms. OVERVIEW VyOS is a GNU/ Linux-based operating system which ties many popular open source applications under a single, unified command line interface. VyOS offers features that are inherent to the traditional hardware routers: commit and rollback functionality, built-in configuration versioning and archiving, scripting APIs. At the same time it provides VPN and firewalls options. One of the most popular use cases for VyOS is connecting an existing enterprise network to the cloud infrastructure or connecting networks that hosted at different cloud platform vendors to each other: Benefits: - Open and community-driven nature of development - Enterprise- and service provider networks oriented - Adaptable for any network - from a small office to a data center rack - Arise from the abandoned Vyatta Core system so you can upgrade old Vyatta Core systems to VyOS without reinstallation - Continues to be actively developed and improved by the community. Services offered: - Commercial support - Development services on demand - Private deployments design and configuration for small and medium-sized businesses (ISPs, MSPs and Enterprise users) - Trainings and workshops KEY FEATURES - Wide range of supported VPN technologies: GRE, IPSec, IPSec VTI, OpenVPN, WireGuard - API for working with configuration from shell, Python, and Perl scripts - Physical and virtual hardware supported equally - Command line interface in the style of JunOS - Wide range of COTS hardware and virtual platforms supported - One-step image build process: any users can build custom images for their needs - Support BGP, OSPF routing protocols - QoS for traffic prioritization and shaping - Safe and easy image-based upgrades.

PROLOGUE “For us, open source isn't just a business model; it's smart engineering practice.” – Bruce Schneier Argument 1: Open Source as a requirement for Security Infrastructure In 2013, Edward Snowden, an Infrastructure Analyst working for Booz Allen Hamilton, a US defense contractor, and assigned to the NSA, provided the public with classified information detailing the extent of NSA programs used to compromise security infrastructure, including the use of backdoors on major network firewall platforms. The list of platforms specifically cited include offerings from Cisco, Juniper, and Huawei. A major concern following these revelations, was not only the ability to trust the integrity of security infrastructure, but also in the perceived disregard or arrogance demonstrated by the NSA in the assumption that these tools or details on how to exploit them would not fall into the purview of bad actors. As a direct result of these events there is a growing sense within the security community that access to source code is a requirement for security.
