Linux distributions can be divided into different categories, depending on their purpose and intended target group. Servers, education, games and multimedia are some of the popular categories of Linux distributions.
For users concerned about security, there are several distributions that are designed to enhanced protection privacy. These builds guarantee protection from tracking your activity while surfing the Internet.
However, our selection includes not only distributions with an emphasis on privacy, but also distributions for conducting intrusion testing. These builds are specifically designed for analyzing and assessing system and network security and contain a wide range of specialized tools for testing systems for potential vulnerabilities.
An Ubuntu-based distribution designed for intrusion testing. By using XFCE as a standard window manager, it works very quickly.
Repositories of software solutions are constantly updated to ensure that the user always has the latest versions of built-in tools that allow you to perform web application analysis, stress tests, assessment of potential vulnerabilities, privileges and much more.
Unlike other distributions, which include a large set of different applications, Backbox does not contain such redundancy. Here you will only find best tools for each individual task or goal. All tools are sorted into categories, making them easy to discover.
Wikipedia presents short reviews many built-in tools. Although Backbox was originally created solely for testing, the distribution also supports the Tor network, which will help hide your digital presence.
Kali
Probably the most popular penetration testing distribution based on Debian Wheezy. developed by Offensive Security Ltd and is a continuation of the earlier BackTrack Linux project.
Kali is available in the form of 32-bit and 64-bit ISO images, which can be burned to a USB drive or CD, or even installed on hard drive or solid state drive. The project also supports the ARM architecture and can even run on a Raspberry Pi single board computer, and also includes a huge number of analysis and testing tools. The main desktop is Gnome, but Kali allows you to create a custom ISO with a different desktop environment. This highly customizable distribution allows users to even modify and rebuild the Linux kernel to suit specific requirements.
Kali's popularity can be judged by the fact that the system is a compatible and supported platform for the MetaSpoilt Framework, a powerful tool that allows you to develop and execute exploit code on a remote computer.
Available for 32-bit and 64-bit machines, it is an intrusion testing distribution that is based on Gentoo Linux. Gentoo users can optionally install Pentoo, which will be installed on top of the main system. The distribution is based on XFCE and supports saving changes, so if you disconnect the USB drive, all applied changes will be saved for future sessions.
The built-in tools are divided into 15 different categories, such as Exploit, Fingerprint, Cracker, Database, Scanner, etc. Being based on Gentoo, the distribution inherits a set of Gentoo security features that allow you to perform additional security settings and more granular control of the distribution. You can use the Application Finder utility to quickly discover applications located in various categories.
Since the distribution is based on Gentoo, you will need to perform some manipulations to get it to work network card and other hardware components. Upon boot, select the verification option and set up all your devices.
Based on Ubuntu, this distribution is designed for intrusion detection and monitoring network security. Unlike other pentesting distributions, which are more offensive in nature, it is a more defensive system.
However, the project includes a large number of offensive tools that are found in other penetration testing distributions, as well as network monitoring tools, such as a sniffer Wireshark packages and Suricata intrusion detection utility.
Security Onion is built around XFCE and includes all the essential applications found in Xubuntu. Security Onion is not intended for amateurs, but rather for experienced professionals who have a certain level of knowledge in the field of network monitoring and intrusion prevention. Fortunately, the project is constantly supported detailed guides and video tutorials to help you work with complex firmware.

Default account: root:blackarch. BlackArch is over 4 gigabytes in size and comes with several different window managers, including Fluxbox, Openbox, Awesome.
Unlike other penetration testing distributions, BlackArch can also be used as a privacy-enhanced tool. In addition to various analysis, monitoring and testing tools, the distribution also includes anti-tracking tools, in particular sswap and ropeadope for securely erasing the contents of the page file and system logs, respectively, and many other privacy programs.
Developed by the Italian IT security and programming network Frozenbox, based on Debian, can be used for intrusion testing and maintaining privacy. Just like BlackArch, Parrot Security OS is a rolling release distribution. The default login for a Live session is root:toor.
The installed Live image offers several boot options, such as persistent mode or persistent mode with data encryption. In addition to analytical tools, the distribution includes several programs for anonymity and even cryptographic software.
Mate's customizable desktop environment offers an attractive interface, and Parrot Security OS itself runs very quickly, even on machines with 2 gigabytes of RAM. The system has several niche utilities built into it, for example, apktool - a tool for changing APK files.
For users who care about privacy, the distribution provides a special category of applications where users can enable anonymous surfing mode on the Internet (using Tor networks) in one click.

Users personal computers give preference to specific Windows options. The versatility and accessibility of popular software has made Microsoft inventions widespread among home and corporate users. Work productivity is important for comfortable use and quick problem solving, so it’s worth asking which system is known as the most fast Windows.
Rating of Windows operating systems
Microsoft released a series of Windows products to the world. Depending on the release date, there are individual software variants that can demonstrate characteristic performance prospects. It's worth taking a look at each of the available options to learn the advantages and disadvantages.
- Windows 8 (8.1);
The fastest Windows is determined by technical parameters. You will need to install different versions of the software on computers with the same configuration in order to compare the performance of the software on the same hardware.
The basic testing participants are special utilities, which help determine the performance of specific aspects of work: image, calculation, loading and other operations. Research on this topic were carried out by different sources, which makes it possible to simply summarize the existing rating.
What determines how fast Windows works?
Each version of the software package is characterized by a thoughtful level of manufacturing. Work performance largely depends on the local resources of the computer - configuration and parameters. The power of the hardware can make every OS promising and productive. Optimization issues also remain open - clearing memory, deleting caches and other tricks. A clean ranking of fast operating systems is only possible when comparing system performance with the same hardware power.
The OS itself affects performance due to its own optimization. Hardware resources are important for performance, but software characteristics affect the correct and beneficial use of available resources. This causes discrepancies in the response speed of different systems on identical computers.
Windows Vista came out in 2007, much later than XP. Vista has not gained user preference. Vista has become known as slow and unstable, which is why it ranks last among the presented developments. Vista has a nice design and a well-thought-out concept, but for the modern user there are no significant advantages to installing Vista.
Windows XP appeared in 2001 and spread quickly. The predecessors to the popular XP were ME and 95. Legacy systems were quickly driven out of the market by subsequent innovations. The XP option is considered suitable for older computers with weak resources. Until today, XP is installed on devices with small capacity RAM and small clock frequency processor.
XP's popularity lasted until 2012. Subsequently, the corporation stopped supporting the product, but the lack of updates does not affect the performance and prospects. The release of new software products moved XP to fourth position.
OS number 7 was developed in 2009. New option Users quickly liked it, so it gained popularity and was installed on computers. Version 7 was the first to supplant XP, providing an updated alternative.
New system received significant software improvements, worked without failures and demonstrated an attractive design. The OS's competition with XP left no doubt - the fast and productive OS received no complaints. The corporation's new development has learned to independently work with networks, install drivers for external systems and protect against viruses.
The presence of updated functionality made Windows 7 popular. Using Windows 7 is found even today. Benefits Realized software product they place the OS in third place in the ranking and give reason to recommend installing the productive Windows 7.
2: Windows 8 (8.1)
Windows 8 was released in 2012. The standard interface is organized for the use of movable tiles. The Start button has been replaced start screen. Users liked the functionality of customizing and grouping launch buttons and expanded the prospects for personalization.
Windows 8 now comes with an app store and support account Microsoft to merge device accounts. Windows 8 did not gain popularity from version 7, although it provided an interesting alternative. It is recommended to install OS 8 for computers with average resource reserves, since the needs for fast operation of Windows 8 are higher than for classic XP.
The variant left the first position in the ranking in 2015. The new OS united strengths the latest options are 7 and 8. 10 quickly gained popularity and was installed instead of the old options. Perspective free update up to 10 became an additional trump card for the corporation.
Windows 10 is supported on devices: computers, netbooks, laptops, tablets and phones. The OS 8 interface, desktop and controls seem familiar and comfortable. The novelty of the solutions ensured the instantaneous operation of everyday processes, programs and games. The developers have introduced functionality for connecting devices on Windows 10 and Xbox One.
Improved security features make Windows 10 resistant to virus attacks and malware. The function of using biometric information and other specific functions has been added. The combination of the listed characteristics becomes the basis for a confident first position in the ranking.
In this age of BYOD, when nearly half of organizations report data breaches and mobile device hacking, and 64% have no BYOD policies at all (according to Veracode), the topic of mobile security has become increasingly relevant to solution providers seeking to protect customer networks.
This places the burden of BYOD on IT departments and VARs to implement best methods protection across a wide variety of devices.
There are, of course, dozens different models smartphones and tablets, but, by and large, it comes down to four main mobile OS platforms: iOS Apple, Android Google, BlackBerry and Windows Phone Microsoft.
The iPhone and iPad have gained widespread adoption in enterprise environments, according to a survey of mobile device administration (MDM) vendors conducted by CRN for this article. Theodora Taitonis, Vice President of mobile technologies at Veracode, believes Apple's success is built on its tight control of the hardware platform, software and app ecosystem, along with thoughtful additions such as new content and app management APIs in iOS 7.
Android, the most popular mobile OS on the planet, has made significant progress in the enterprise segment, although antivirus vendors provide a long list of malware that Android devices sometimes succumb to. Samsung - the main vendor in the Android segment - strongly emphasizes its SAFE (Samsung Approved For Enterprise) and proprietary technology Knox protection built into some models in an effort to make the OS more attractive to organizations.
Microsoft offers unique features in its Windows Phone 8, most notably Active Directory integration, allowing MDM vendors to improve administration and assign policies to user groups. There is also, of course, built-in support for Active Sync. And security experts say Windows Phone 8 makes great strides in sandboxing.
Finally, there's BlackBerry, which has (and still retains) enormous respect among solution providers for its many security features, such as its BBM service and the security features in its retooled BES 10 admin server. The OS now includes support for Exchange Active Sync and new technology Balance, which allows organizations to create a partition on their BlackBerry 10 device to keep personal and corporate data and applications separate.
"Consumers tend to gravitate toward the brighter side of the mobile market," says Veracode's Titonis. But this is not always reliably protected. “The burden of BYOD lies with the end user, who must right choice smartphone or tablet and use them safely,” she added.
As for security threats and violations of privacy of mobile devices, even the most secure mobile OS cannot eliminate them if the user does not have basic common sense, she says.
Jerry Zigmont, owner of the reseller company MacWorks, which cooperates with Apple, agrees with this. "I don't think there's any one phone that's more secure than all the others," he said. However, he believes Apple and iOS 7 have some advantage over Android, Windows Phone 8 and BlackBerry.
iOS: the most secure
This is what mobile security experts and solution providers think. U Apple advantage, they say, because it holds in its hands a significant part of all components - the application layer ( App Store), operating system(iOS) and the devices themselves (iPhone/iPad), but not the infrastructure (it is provided by telecom operators).
“iOS is the most secure because it pays as much attention to security at the application level as it does at the operating system level,” says Ira Grossman, director of client device technology at MCPc, a major US-based solution provider with its own Anyplace Workspace platform.
"If applications aren't secure, it doesn't matter how secure the operating system is," Grossman says. "The Apple Store provides a level of security that we don't have in the standard Android app store today."
But just because Apple strictly monitors its App Store does not guarantee an advantage over competitors in app security. According to Veracode, mobile applications Apple poses just as many potential risks as its closest competitor, Android, when it comes to top threat types.
After analyzing thousands of iOS and Android apps used by its customers, Veracode found an almost equal number of cases of unsecured storage of proprietary information such that a hacker could steal financial or stored identity data from the app. Veracode also found equal vulnerability in application error handling, which can be used in cross-site scripting attacks, where a script taken from a website is allowed to execute and can be used to steal information or run other malware on the device.
“Apple is the furthest in security. Each application runs separately (sandboxed), that is, data storage and memory are isolated. And it has the most control over how patches are installed,” said one security expert at an MDM firm who requested anonymity.
Patch level management and control over the installation of updates is an important advantage that Apple has over Android, many MDM vendors say. Apple sends its own patches directly to users, meaning any vulnerabilities found are fixed within 24 hours. This gives Apple an advantage, they say, since Android relies on carriers wireless communication, which send out their patches and OS updates to fix security holes. To make matters worse, the Android segment is fragmented: different hardware platforms and OS version numbers can sometimes require a separate patch for each version.
Unlike Apple, Android devices use a hodgepodge of different variants of the OS. Unfortunately, operators are in no hurry to send patches to devices. Even MDM vendors admit that they have difficulty covering all versions.
Android: strong second place
But this does not mean that Android OS is not secure. It has many built-in security features. In addition, manufacturers of Android devices, primarily Samsung, have improved versions of this OS by adding advanced security features, such as Knox technology (Samsung).
However, for the Knox platform to work effectively, an organization must first implement enterprise-grade management for Knox devices. This platform relies on virtualization to ensure complete separation of work and personal data on mobile devices.
With that in mind, Ojas Rege, vice president of strategy at MDM vendor MobileIron, says Android's security and admin capabilities are nearly equal to those of Apple. “The key to security is an application-isolated architecture, where data in an enterprise application cannot be accessed by another application. iOS provides the strictest isolation. But more secure versions of Android, for example, with Samsung’s Knox technology, are also just as good.”
BlackBerry: is a rebirth possible?
BlackBerry OS also remains popular in certain circles. With its BlackBerry Enterprise Server (BES), it includes hundreds of security features for organizations.
“BlackBerry is the most secure. That's the only reason she's still alive, says Steven Kantorowicz, president of VAR company CelPro Associates. “That’s why government agencies and even President Obama use it.”
If nostalgia and well-deserved respect could increase market share, then BlackBerry would overtake Apple tomorrow, but alas! - many in the industry believe that it is steadily fading. As a result, there is an exodus of developers, and MDM vendors are also switching to other platforms. If the numbers are any indication, BlackBerry's future looks bleak. MobileIron's Rare says BlackBerry's share among the organizations it works with is falling rapidly.
According to a recent MobileIron study, half of the companies that administer BlackBerry smartphones say they plan to stop supporting them in the next 12 months. In the financial services sector, 44% of mobile devices are BlackBerry. According to a MobileIron survey, this figure will drop to 30% in the next 12 months.
However, BlackBerry CEO John Chen allowed himself to disagree with the subverters. At the World Congress mobile communications In February, he told a crowd that the company was set to re-enter the smartphone market with a new high-end model with a QWERTY keyboard called the BlackBerry Classic, slated for release this year.
In an interview with USA Today, Chen described the model this way: “This is an improved and expanded version of one of our most popular and successful products, which was called Bold. It will have a keyboard and a good touch screen, Very fast internet, web browser and multimedia tools. And besides, it will be very protected.”
Chen has repeatedly stated that BlackBerry is the most secure platform in terms of the device itself and message forwarding (as email, and BBM), and safety is at the forefront of the company's development plans.
Windows Phone 8: a force to be reckoned with
Research from ComScore shows that Android and Apple together hold more than 93% of the market today (Android's share is 52%, Apple has 41%), with Windows Phone 8 and BlackBerry vying for a distant third place, with 3.4% and 2. 9% respectively.
Although Microsoft's market share is only a few percent, its advantage over BlackBerry is its tight integration with the corporate environment. "Windows Phone is a central part of our offering because we think it has great potential in the enterprise segment," says MobileIron's Regé.
Security experts say Windows Phone 8 has significantly improved app isolation. But the OS supports fewer MDM policies compared to iOS, meaning vendors like MobileIron can't provide the same level of control for the OS, Regé says.
"Windows Phone 8 is well suited to satisfy information professionals, but not those who must meet high levels of regulatory requirements and security," said Ryan Smith, lead security engineer at startup Mojave Networks.
For these reasons (and due to low demand), Windows Phone 8 is low on many experts' list of safe options. But that doesn't mean MDM vendors don't provide support - most do.
If BlackBerry is clearly lacking vitality, then Windows Phone 8 has a horizon of possibilities. Mobile security is an elusive goal, Smith says. Building on a strong presence in the corporate segment and acquired businesses Nokia smartphones Microsoft could change the security balance with the new release of its mobile OS, he said.
Every day, smartphones are attacked by hackers and malware, so the operating system must be as secure as possible to protect the user's personal data.
In this article we will look at popular mobile operating systems and find out which one is the most secure.
Android
Google's mobile operating system is one of the weakest in terms of security. Experts report that an attacker can hack a smartphone simply by sending a multimedia message to it. However, on latest versions Android is given special attention security, so the situation is not so critical.
Since Android is an open source system source code, developers can use it for their own purposes for free. In other words, Android is a big target for hackers and malware. Last year, about 97% of malware was created specifically for Android devices.
Shop Google Play Store cannot guarantee complete safety when downloading and installing applications, and if you download programs from other sources, the risk of virus infection increases rapidly.
The reality is that Android is the most used mobile operating system in the world, which means it is more profitable to hack.
BlackBerry
The popularity of BlackBerry smartphones has fallen sharply over the past few years, despite very good reviews about the latest devices. The company changed its own mobile operating system to Android, which still did not save it from failure.
Many government officials used BlackBerry smartphones because they were considered the safest.
The BlackBerry operating system used end-to-end encryption, regardless of the smartphone model. Unfortunately, BlackBerry is a thing of the past.
Ubuntu Touch
After the release of the first Ubuntu smartphone last year, many predicted that manufacturers would switch from Android to Linux system, which is Ubuntu.
For those who don't know about Ubuntu Touch, it is an open source operating system similar to Android that is completely free, supported by the Free/Libre Open-Source Software community and Canonical Ltd.
In one of our articles we talked about how you can.
Ubuntu has high level virus protection, however, it is an open source operating system, so malware may still end up on mobile devices.
Shop Ubuntu applications is more secure than Google Play Store. Moreover, the owner mobile device must grant certain permissions before installing the application.
Another plus is the fact that Linux is not the most popular platform today, so attackers have little desire to hack this system. To give you an idea of the situation, as of October 2015, a total of 15 people were affected by the hack.
Large companies such as Netflix, Snapchat and Dropbox use operating Ubuntu system. If you're still not impressed, then perhaps you'll change your mind after learning that the International space station and the Large Hadron Collider also run on Ubuntu.
Windows Phone and Windows 10 Mobile
Microsoft keeps its Windows App Store on a short leash, so unless you want your Windows Phone to be jailbroken, you should only use official services to download apps. Main feature apps on Windows Phone is that they don't interact with each other unless you give permission
Feature new version operating room Windows systems 10 Mobile is a device encryption that essentially locks the smartphone if it is lost. This is done using sophisticated BitLocker technology. If you don't have an encryption key, your files are unreadable. The encryption key is a PIN code that you must enter in Settings > System > Device encryption.
iOS
Just like the Google Play Store is the main repository for Android applications, the App Store stores all applications for iOS devices.
operating room iOS system is closed. This means that only Apple can make changes and updates to the platform. It would seem that this guarantees the maximum level of security, but not quite.
For example, about 500 million users of the Chinese messaging app WeChat were hacked after the release of a modified version of Xcode that was approved by Apple.
Many of you have heard about the hacking of celebrity iCloud accounts. If Apple used to be a guarantor of security, today the company is not so vigilant about it.
In terms of popularity, iOS is second only to Android, so it is not surprising that attackers are looking for security holes in the operating system.
Among the positive qualities of iOS, it is worth noting that mobile platform really hard to hack. Not long ago, the FBI detained a terrorist, after which they asked Apple to provide data from his iPhone smartphone. The company refused. In the end federal services found a hacker who agreed to hack an iOS device for $1.3 million. If it was so easy to hack iOS, they wouldn't agree to pay such a large amount of money, right?
Who is the winner?
Each operating system has its pros and cons.
Android: If you carefully monitor your online activities and suspicious links, messages and MMS, and download applications only from the Google Play Store, you will probably never find out about hacks and viruses on your Android device.
Nexus smartphones, now already Google Pixel are the most secure Android devices.
BlackBerry: Old versions of the operating system BlackBerry really had a high level of security. However, the company switched to using Android platforms for their devices, so they are at the same risk of infection as other Android smartphones.
Ubuntu: While it appears to be the most secure operating system available today, we're not sure it will remain so when (and if) the number of active users increases.
Windows Phone: The same can be said for smartphones on Windows based. When market share increases, the number of hacks and virus attacks increases. However, on at the moment The system looks very reliable.
iOS: Despite a number of recent security issues, Apple enjoys a high level of trust among users. Given the fact that the operating system is closed, the company can quickly detect malware and take the necessary measures to close the security hole.
Which one do we recommend the most? secure smartphone right now? If you prefer an older device, then the BlackBerry Priv is a good option. If you want something newer, you should choose a device running Ubuntu.
Remaining anonymous on the Internet is not always the same as surfing the web safely. It is important to keep the maximum technical information your device is safe from prying eyes so that attackers cannot take advantage of your system's vulnerabilities and steal your sensitive data and use it for their own purposes, which can bring serious consequences.
If you want to remain anonymous online and protect your data, in this article we will look at the most secure Linux distributions that will help you do this.
Most of the tools listed in this article are completely free to use. Besides them, there are paid options, for example, VPN, but these free tools they do their job much better. The need for security on the Internet is constantly growing, and there is always the risk of cyber attacks and eavesdropping by intelligence agencies. It is not surprising that several distributions were immediately created, combining tools that provide maximum anonymity on the network.
These distributions were initially aimed at narrow specialists, but recently they have gained great popularity. Due to the demand for such systems from users, they are constantly being developed and new ones are being added, perhaps now there are more than twenty of them, but we will consider only the best secure Linux distributions.
Most of them use Tor software for anonymity, which provides a truly high level of anonymity, unlike VPN providers who still know your real IP address.
But VPN still has many advantages, which makes it the best option in some cases. If connection speed is important to you or you plan to transfer files via P2P, a VPN will win.
Before looking at the most secure Linux distributions, let's talk about how Tor anonymity is ensured. Tor or The Onion Router is a standard encryption protocol developed by the US Navy.
Tor software works with multiple nodes, which ensures high reliability and anonymity. When data passes through a random node, it is re-encrypted each time and becomes fully decrypted only at the last node. The Tor developers are also responsible for creating the Tails distribution, which Edward Snowden recommends.
Now let's get back to the VPN. Usually these are paid services, find a good one, free VPN very difficult. The quality of VPN service depends on the provider, but generally the speed is VPN servers much faster than Tor.
1. Tails - anonymous LiveCD
If you want to remain anonymous on the internet, Tails is a great choice. Its main purpose is to ensure that you don't leave any digital traces while surfing the web. This is one of the most commonly used distributions for anonymity, and the only one where all Internet connections are routed through Tor.
Typically, Tails is installed on a flash drive, all data is stored in RAM, and is erased after completion of work. The operating system is based on Debian and comes with a large set of open source tools specifically designed to ensure privacy. Substitution is supported here MAC addresses and Windows camouflage, when the system looks very similar to Windows 8.
Tails uses outdated version Gnome, which looks ugly and minimalistic without the ability additional settings and improvements since files are not saved between sessions. This may not matter to many because Tails gets the job done. The distribution has excellent documentation and you can read it on the official website.
2. JonDo Live-DVD
JonDo Live-DVD is a commercial solution for online anonymity. It works in a similar way to Tor, with your data also being transferred through a series of mixed JonDonym servers. At each node, the data is re-encrypted. This is a great alternative to Tails, especially if you're looking for something with less limitations user interface.
Like Tails, the distribution is based on Debian, and also includes a set of tools for ensuring anonymity and the most commonly used applications.
JonDo Live-DVD is paid service, for commercial use. It is aimed at use in companies, and is also faster than Tails and also does not support saving files.
If you want something completely different, you'll be interested in Whonix. A completely different approach is used here. This is not a LiveCD. Whonix works in virtual VirtualBox machine, the system is isolated from your main system, thereby reducing the risk of picking up viruses or exposing your data on the network.
Whonix consists of two parts. Whonix Gatway acts as a Tor gateway, the second - Whonix Workstation is completely isolated from the network and routes all its network connections via Tor gateway.
So here you need to use two virtual machines, which can create some problems if you have weak hardware. But nevertheless it works. However, it is not the most secure Linux distribution like Live CD, since it does not save data to the hard drive.
Whonix is based on Debian, but uses KDE as its desktop environment. The operating system is not suitable for everyday use and you can only use it on a virtual machine.
4.Qubes OS
This is another anonymity distribution recommended by Snowden. Qubes tries to correct the shortcomings of all previous distributions that lacked a beautiful and customizable user interface. This is a distribution for everyday use that combines the power of Tor and Whonix.
This is a completely different approach to anonymity. The idea behind Qubes is security by separation. This means your digital life will be divided between isolated virtual machines. Any application runs in a separate virtual environment.
It should be noted that Qubes comes standard with Purism's flagship laptop. This laptop is considered the most safe device for users. And this is true, given the powerful software this distribution.
If you want a convenient distribution for everyday use with all the standard functionality and familiar applications, Qubes OS can be a great choice. Unlike those listed above, it can be installed on a hard drive.
5. UPR (Ubuntu Privacy Remix)
UPR is another installable distribution that focuses on security. It is user-friendly and provides an isolated environment where sensitive data can be kept safe.
Just from the name, you can tell that it is based on Ubuntu. The distribution offers secure Internet surfing and the use of encrypted flash drives to effectively protect your data from unauthorized access. The distribution comes pre-installed with encryption tools such as GnuPG and TrueCrypt. UPR is only for safe internet surfing and not for anonymity. It's great if you want to install the system on your computer rather than use a LiveCD. If you also need anonymity, you can install Tor or connect a VPN.
Conclusions
Considering that Tails is the most common of all mentioned in this article, we can decide that it is the safest. But other distributions serve their purpose well too. So it all comes down to personal preference.
