  • Physical Or Virtual Firewall for Perimeter Protection in Cloud Computer Infrastructure
    16th INTERNATIONAL CONFERENCE ON INFORMATION SYSTEMS & TECHNOLOGY MANAGEMENT - CONTECSI - 2019 DOI: 10.5748/16CONTECSI/ITM-6115 PHYSICAL OR VIRTUAL FIREWALL FOR PERIMETER PROTECTION IN CLOUD COMPUTER INFRASTRUCTURE Thiago Mello Valcesia - IPT - Instituto de Pesquisas Tecnológicas - [email protected] Antonio Luiz Rigo - IPT - Instituto de Pesquisas Tecnológicas - [email protected] SUMMARY This article presents an examination of the different types of firewalls geared toward protecting Datacenters. The idea is to perform a survey of the different ways of installation, the safety perceived by customers, the positive and negative points of each model and the market trends for perimeter protection. In addition, it is intended to categorize rules, protection filters, application inspection criteria and services offered by firewalls, by analyzing the various protection schemes available in firewalls, regardless of the structure as a service in Cloud adopted. Keywords: Physical firewall, Virtual firewall, Cloud firewall, Security, Cloud Computing. INTRODUCTION The term Digital Security is increasingly present in our daily lives. The need to protect computers or prevent corporate networks from receiving unnecessary traffic, improper access, and unknown packets, coupled with the concern of professional information security staff about content accessed by Internet users, make data control a vital task. Firewall is much more than a "fire wall" isolating the company network from the external world represented by the Internet. The Firewall function is therefore essential to raise the level of security of the internal environment, protecting it from external attacks, increasing security and reducing the vulnerability of the local network. There are currently three Firewall alternatives to install on enterprise networks that aggregate cloud network segments: 1.

In this paper, we analyze the exploitability of cloud networking services (which are shared among cloud tenants) and introduce a practical method for build- ing information leakage channels by monitoring workloads on the cloud networking services through the virtual firewall. We also demonstrate the practicality of this attack by implementing two different covert channels in OpenStack as well as a new classof side channels that can eavesdrop on infrastructure-level events. By utilizing a Long Short-Term Memory (LSTM) neural network model, our side channel attack could detect infrastructure level VM creation/termination events with 93.3% accuracy.

  • The Virtual Firewall
    The Virtual Firewall Vassilis Prevelakis Computer Science Department Drexel University 1. Introduction The trend towards portable computing means that the traditional security perimeter architecture (where a firewall protects computers in the LAN by controlling access to the outside world) is rapidly becoming obsolete. This has resulted in a number of products described as “personal firewalls” that control that computer’s access to the network and hence can protect it in the same way as a traditional firewall. Existing systems such as Windows and most Unix and Unix-like systems already provide security features that can be used to implement firewall functionality on every machine. However, the difficulty of securing general purpose operating systems has im- peded the widespread use of this approach. Moreover, it is difficult to ensure that a secured sys- tem remains secure after the user has had the opportunity to install software and perform recon- figurations and upgrades. Recognizing the futility of attempting to secure the user machines themselves, in [Prev03, Denk99] the authors proposed the use of a portable “shrink-wrapped” firewall. This was a sepa- rate machine running an embedded system that included firewall capabilities and was intended to be placed between the general purpose computer and the network. The problem of securing the firewall became much simpler as it utilized a special-purpose firewall platform with a highly controlled architecture. Sadly, the proposal saw limited adoption because carrying around yet another device is expensive and inconvenient. To make matters worse, if the external device is lost or damaged the user will be presented with a dilemma: remain disconnected from the net- work until the firewall box is replaced, or accept the risk and connect the laptop directly to the unprotected network.

People mention that it is a “game changer”. The main purpose of this thesis is to prove virtualization works and is better than existing home network environments. In the Related Works section we explore other topics which relate to what we set out to achieve. There are some interesting related works which we describe here, mainly SoftEther and OpenWRT. Taking both subjects together, try to get them working with each other to achieve a Virtual Dynamic Host Control Protocol, VDHCP server. We also explore another important topic on how to tether a Linux Customer Premises Equipment, CPE, for IP Service Delivery. A thesis completed in BTH was also reviewed. This discusses the various different VPN solutions available to use in today’s Internet. The next chapter in my thesis, Methodology, will describe how we designed, implemented and configured a system to achieve Virtualizing a Network Function in the Home Environment, more specifically DHCP.

While software implementation of network functions on commercial off- the-shelf (COTS) hardware. To substantiate its roll out, a number the Advanced Configuration and Power Interface (ACPI) of issues (e.g., COTS’ inherent performance and energy efficiency, specification [2] equips most – if not all – of it with power virtualization overhead, etc.) must be addressed, in a scalable and management mechanisms (e.g., Low Power Idle (LPI) and sustainable manner.

  • 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].

This radical change has facili- tated the provisioning of advanced and flexible network services, ultimately helping system administrators and network operators to cope with the rapid changes in service requirements and networking workloads. This thesis investigates the challenges of provisioning network security services in “softwarised” networks, where the security of residential and business users can be provided by means of sets of software-based network functions running on high performance servers or on commodity compute devices. The study is approached from the perspective of the telecom operator, whose goal is to protect the customers from network threats and, at the same time, maximize the number of provisioned services, and thereby revenue. Specifically, the overall aim of the research presented in this thesis is proposing novel techniques for optimising the resource usage of software-based security services, hence for increasing the chances for the operator to accommodate more service requests while respecting the desired level of network security of its customers.
