Best Secure Operating System

Security is a very important thing today, including the operating system, and it is a difficult or even controversial subject to examine. Only operating systems with no external links are secure. They will inevitably have some form of vulnerability or flaw that may be exploited, just like any other operating system. Any network OS may be detected if its settings are used carefully, without exception.

In this article, you will learn about the best secure operating system with their features. The topmost secure operating systems are as follows:

  1. Qubes Operating System
  2. OpenBSD Operating System
  3. Whonix Operating System
  4. TAILS Operating System
  5. Debian Operating System
  6. Linux
  7. Kali Linux
  8. Blackarch Operating System
  9. Pure Operating System
  10. Elementary Operating System

Qubes Operating System

Best Secure Operating System

Qubes operating system is a desktop operating system that goals to provide security by isolating users. It is a highly secure open-source operating system designed for single-user devices. It uses Xen-based virtualization to describe computer programs into isolated virtual machines known as qubes. It provides various settings through the usage of virtualization.

Features of Qubes Operating System

There are various features of the Qubes Operating System. Some features of the Qubes Operating System are as follows:

  1. Qubes operating system allows isolated virtual machines (qubes) to share root files without compromising system security.
  2. Qubes may run on various operating systems at the same time, including Windows, Fedora, and Debian.
  3. Installed software is isolated by Qubes, making it appear as if it were installed on a different computational entity.
  4. It is easy to use two-factor authentication using the Qubes U2F proxy.


Best Secure Operating System

OpenBSD operating system is one of the most secure operating systems currently available. It operates on a multi-platform 4.4 BSD Unix-based operating system that is currently available. The Open BSD operating system was created by a group of volunteers at the University of California's Berkeley Software Distribution Center. It is preferred because of its policy of complete disclosure. It allows the Open BSD OS's developers to be entirely transparent about any security flaws they may have uncovered.

OpenBSD is becoming increasingly popular with experienced technical users due to its minimalistic and secure operating system, which focuses on enhancing the security of its operating system at the expense of user satisfaction. As a result, it is not an operating system for low-skilled end users unless you want to learn to code. Other advantages of the Open BSD OS include built-in cryptography, portability, accuracy, proactive security, compatibility, standardization, and a small system footprint.

Features of OpenBSD Operating System

There are various features of the OpenBSD Operating System. Some features of the OpenBSD Operating System are as follows:

  1. By default, OpenBSD disables all non-essential programs and daemons and reduces the risk of users encountering security concerns.
  2. It runs on the multi-platform 4.4BSD operating system, which is a Unix-based platform with strong security features.
  3. OpenBSD OS includes OpenSSH, which is cryptographic software for encrypting user data.

Whonix OS

Best Secure Operating System

Whonix is a secure and private operating system that reduces the risk of outside spies or attackers. It is based on Debian and Tor's open relay network software. These shields users against network spying while allowing them to use the system normally. One of Whonix's claims to fame is its security against malware and DNS intrusions, which are made nearly difficult so that the user's ID address remains secret.

Whonix comprises two virtual computers within the Debian base, which are a "Workstation" and a "Tor Gateway". Both virtual machines install the images on a user-supplied host OS, and Qubes, Linux KVM, and VirtualBox are compatible engines. All network connections are compelled to travel through the Workstation, which filters through Tor and routes them to the Internet. Applications are also not permitted to leave the Workstation.

It also includes various features, including instant messengers, Tor Browser, Tox, secure data transfer, Tor Messenger, encrypted email, and web server administration with Apache and a host of other software programs.

Features of Whonix Operating System

There are various features of the Whonix Operating System. Some features of the Whonix Operating System are as follows:

  1. The vanguard feature of Whonix protects users from third-party tracking and data traffic analysis.
  2. Whonix operating system prevents keystroke logging by malware residents on the users' system.
  3. Whonix sends all of its data across the Tor network, making it harder to discover users' IP addresses and whereabouts. The operating system is DNS, ICP, ISN, and CPU leakproof.


Best Secure Operating System

The TAILS operating system is a secure and portable operating system that uses the Tor network to protect users' online privacy while also assisting them in circumventing internet censorship. It is one of the most secure OS due to its flexibility.

The TAILS operating system was initially created for the Project Secure Whistleblowers in order to protect whistleblower's identities. Although, regular users may download and use the TAIL OS for free if they want to protect their privacy and data flow.

Features of TAILS Operating System

There are various features of the TAILS Operating System. Some features of the TAILS Operating System are as follows:

  1. It is a small operating system that can be downloaded and run the operating system from an SD card or other temporary storage device.
  2. TAILS installs and runs without using a third-party OS on a USB storage device.
  3. TAILS provides a series of secure tools for securely communicating and working on sensitive documents.
  4. Because of its compatibility with a wide range of devices and operating systems, the TAIL operating system may be used as a backup to your primary operating system. As a result, it may be an excellent complement to the most widely used Windows operating system.
  5. TAILS removes all traces of your activities when you shut down the system.

Debian OS

Best Secure Operating System

Debian is an operating system (OS) that is free to use. It is a variant of Linux. An OS is a set of programs and tools that enable your system to function. The kernel is the core of any OS. The kernel is an essential program on the computer, and it does all basic housekeeping and allows other applications to run. Debian is based on the Linux kernel, a completely free piece of software developed by Linus Torvalds and supported by (perhaps over 1000) individuals worldwide. The GNU project provides a substantial portion of the core tools that comprise the operating system, and these tools are also free.

Debian is the way to go if you want a rock-solid stable system with many open-source goodies in its repository. It has another advantage is the ability to manage deb packages.

Features of Debian OS

There are various features of the Debian operating system. Some features of the Debian operating system are as follows:

  1. It has been tested. It has the same level of stability as many other distributions.
  2. It's quite old. Many good developers stuck with Debian, and the community is mature.
  3. APT is sufficient, and Debian has one of the most extensive software repositories.
  4. It is concerned with software freedom. Non-free software is split into its category within Debian repositories, and it is one of the few distributions that constantly use GNU/Linux in its name.

  2. The System Firewall restricts incoming and outgoing network traffic by utilizing the Linux kernel's Netfilter framework.
  3. The number of resources that an application or account can consume in its operations is limited by resource allocation control.
  4. Software management is a repository of software files used to ensure that all system software is updated.
  5. The file permission feature controls how users access files and directories on a Linux OS. Users may or may not be able to read, write, or execute program files, depending on the sorts of permissions provided for file access.
