An Investigation Into the Security and Privacy of Ios VPN Applications
An Investigation Into the Security and Privacy of iOS VPN Applications Jack Wilson Division of Cybersecurity School of Design and Informatics Abertay University, Dundee A thesis submitted for the degree of Bachelor of Science with Honours in Ethical Hacking 1st May 2018 Word Count: 11,448 Abstract Due to the increasing number of recommendations for people to use VPN’s for privacy reasons, more app developers are creating VPN apps and publishing them on the Apple App Store and Google Play Store. In this ‘gold rush’, apps are being developed quickly and, in turn, not being developed with security fully in mind. This paper investigated a selection of free VPN applications available on the Apple App Store (for iOS devices) and test the apps for security and privacy. This includes testing for any traffic being transmitted over plain HTTP, DNS leakage and transmission of personally-identifiable information (such as phone number, IMEI 1, email address, MAC address) and evaluating the security of the tunnelling protocol used by the VPN. The testing methodology involved installing free VPN apps on a test device (an iPhone 6 running iOS 11), simulating network traffic for a pre-defined period of time and capturing the traffic (either through ARP spoofing, or through a proxy program such as Burpsuite). This allows for all traffic to be analysed to check for anything being sent without encryption. Other issues that often cause de-anonymisation with VPN applications such as DNS leakage can be tested using websites such as dnsleaktest.com. The research found several common security issues with the VPN applications that were tested, with a large majority of the applications tested failing to implement HTTPS. -

Best VPN Services in 2017 (Speed, Cost & Usability Reviews)
10/8/2017 Best VPN Services in 2017 (Speed, Cost & Usability Reviews) Best VPN Services VPN Reviews & In-Depth Comparisons Brad Smith Sep 18, 2017 With the help of John & Andrey (https://thebestvpn.com/contact-us/), we’ve put together a list of best VPNs. We compared their download/upload speed, support, usability, cost, servers, countries and features. We also analyzed their TOS to see if they keep logs or not and whether they allow P2P and work with Netflix. here’s a link to the spreadsheet (https://docs.google.com/spreadsheets/d/11IZdVCBjVvbdaKx2HKz2hKB4F Z_l8nRJXXubX4FaQj4/) You want to start using a VPN, but don’t know which software/service to use? In this page, we’ve reviewed 30+ most popular VPN services (on going process). In order to find out which are best VPNs, we spent some time on research and speed testing: 1. Installed 30+ VPN software on our personal devices, such as Windows, Mac, Android and iOS and compared their usability. 2. Performed Download/Upload speed tests on speedtest.net to see which had best performing servers. 3. Double checked if they work with Netflix and allow P2P. 4. Read their TOS to verify if they keep logs or not. 5. Compared security (encryption and protocols). That means we’ve dug through a large number of privacy policies (on logging), checked their features, speed, customer support and usability. If you know a good VPN provider that is not listed here, please contact us and we’ll test it out as soon as possible. 5 Best VPNs for Online Privacy and Security Here are the top 5 VPN services of 2017 after our research, analysis, monitoring, testing, and verifying. -
Best Free Vpn for Torrent Download Best Free VPN for Torrenting – Our Top 3 Picks for 2021
best free vpn for torrent download Best Free VPN for Torrenting – Our Top 3 Picks for 2021. Torrenting is something we often use as a shortcut to our favorite movies, games, music, and e-books. However, with ever-growing anti-torrenting laws worldwide, people are getting concerned about their privacy while performing this activity. By using a VPN, you can easily stay off the radar and become invisible to the prying eyes of your ISP and the government. But can free VPNs help you do so? And what are the best choices for that matter? Let’s find out below. Free VPNs – Can They Match Premium VPNs for Torrenting? Before we delve deeper into the subject, we need to clarify a few things. On the market, there are two types of VPNs – free and premium. Some premium providers offer their free versions but as expected, they’re quite inferior, to make you go for a premium variant. You need to remember one thing, though – free providers are ALWAYS inferior to paid ones. There are many reasons for that. However, since we’re focused on torrenting in this article, we’ll talk about issues that will have a direct impact on your P2P activities if you go for a free VPN, even if it is the best one. Slow Speeds. Every free VPN provider will give you very slow speeds whether you are torrenting or watching videos. Now, all providers reduce your native internet speed to some extent. This is a small price to pay for all the security features and military-grade encryption you get. -

What Is a Virtual Private Network?
C H A P T E R 1 What Is a Virtual Private Network? A virtual private network (VPN) allows the provisioning of private network services for an organization or organizations over a public or shared infrastructure such as the Internet or service provider backbone network. The shared service provider backbone network is known as the VPN backbone and is used to transport traffic for multiple VPNs, as well as possibly non-VPN traffic. VPNs provisioned using technologies such as Frame Relay and Asynchronous Transfer Mode (ATM) virtual circuits (VC) have been available for a long time, but over the past few years IP and IP/Multiprotocol Label Switching (MPLS)-based VPNs have become more and more popular. This book focuses on describing the deployment of IP- and IP/MPLS-based VPNs. The large number of terms used to categorize and describe the functionality of VPNs has led to a great deal of confusion about what exactly VPNs are and what they can do. The sections that follow cover VPN devices, protocols, technologies, as well as VPN categories and models. VPN Devices Before describing the various VPN technologies and models, it is useful to first describe the various customer and provider network devices that are relevant to the discussion. Devices in the customer network fall into one of two categories: • Customer (C) devices—C devices are simply devices such as routers and switches located within the customer network. These devices do not have direct connectivity to the service provider network. C devices are not aware of the VPN. • Customer Edge (CE) devices—CE devices, as the name suggests, are located at the edge of the customer network and connect to the provider network (via Provider Edge [PE] devices). -

The Impact of Media Censorship: Evidence from a Field Experiment in China
The Impact of Media Censorship: Evidence from a Field Experiment in China Yuyu Chen David Y. Yang* January 4, 2018 — JOB MARKET PAPER — — CLICK HERE FOR LATEST VERSION — Abstract Media censorship is a hallmark of authoritarian regimes. We conduct a field experiment in China to measure the effects of providing citizens with access to an uncensored Internet. We track subjects’ me- dia consumption, beliefs regarding the media, economic beliefs, political attitudes, and behaviors over 18 months. We find four main results: (i) free access alone does not induce subjects to acquire politically sen- sitive information; (ii) temporary encouragement leads to a persistent increase in acquisition, indicating that demand is not permanently low; (iii) acquisition brings broad, substantial, and persistent changes to knowledge, beliefs, attitudes, and intended behaviors; and (iv) social transmission of information is statis- tically significant but small in magnitude. We calibrate a simple model to show that the combination of low demand for uncensored information and the moderate social transmission means China’s censorship apparatus may remain robust to a large number of citizens receiving access to an uncensored Internet.
