Growing digitalization has led to an increase in the need for digital security and privacy. With this comes the requirement to have secured operating systems. Operating System (OS) security protects sensitive data and maintains personal privacy. As awareness grows regarding the associated privacy risks of conventional systems, like those provided by Windows and ChromeOS, there tends to be an increasing inclination toward alternative systems emphasizing security, privacy, and anonymity.
This comprehensive approach provides a complete understanding that can help you make the right decision regarding the secure OS that would comply with your requirements. As cyber-attacks continue to rise and data breaches become regular, one question follows: What OS provides the most protection? But it’s not as straightforward as one might be led to believe.
Macs are often considered virus-free, and Windows systems are considered less safe than any other OS on the market. However, ChromeOS was intentionally built with security in mind and has often been the safe choice. That’s all good, except its user base is only relatively small.
The bottom line is that no OS is completely immune. With the constantly changing landscape of cyber threats, today’s secure OS can be vulnerable tomorrow. It’s, therefore, very reasonable to spend a little money on affordable antivirus options such as Surfshark One, no matter what one’s OS may be.
In this article, you’ll explore the operating systems, gaining valuable insights into their privacy features and security measures. It will give an overview and review criteria, encompassing factors such as ease of use, compatibility, and performance. Let’s understand each OS’s emphasis on privacy, security, and anonymity, scrutinizing their key security features, practical applications, and strengths and weaknesses.
Privacy, Anonymity, and Security
Three fundamental principles apply when defining secure operating systems: privacy, anonymity, and security. These principles, applied correctly, provide a working background for choosing an operating system.
Privacy ensures that all your activities are hidden from evil eyes, but your identity is known. It entails protecting sensitive information, such as the data associated with you and information that you send and receive, from a breach or leak.
Imagine sending a sealed letter in an envelope with your name and the contents being sealed. Your contents are hidden, but you are known.
On the other hand, Anonymity ensures that the identity is hidden, but the actions are known. Protecting against targeted attacks due to online behavior and maintaining freedom of expression online is necessary.
Anonymity is likened to sending a postcard without a return address. Your message is seen, but your identity is not known.
Security is the ability of assets, such as privacy and anonymity, to withstand adversaries. It involves protection using a Virtual Private Network, encryption, and regular software updates. Security measures are designed to consider various threats and adversaries, provided that technology, practices, and protocols are involved.
Imagine sending letters that are locked. Your post will be safe, and these changes will keep your privacy and anonymity from theft or tampering.
While privacy, anonymity, and security differ, they are interrelated and help protect your digital identity. The elements must be balanced properly as perfect privacy, security, and anonymity are impossible simultaneously and could be for individuals based on one’s requirements and conditions.
What is an Operating System?
An Operating System is a major intermediary between the user of a computer and the hardware constituent of a computer. It is a software platform that performs primary activities like file management, memory management, process coordination, and handling of inputs and outputs, as well as peripheral devices like disk drives and printers.
An operating system is software that ensures interaction between applications and computer hardware. The kernel, which contains the core functionalities, is the main part of an operating system.
An operating system’s main functions include providing the means for interaction between applications and hardware and managing a system’s hardware and software resources.
Operating Systems are everywhere and can be found on almost every type of device, including but not limited to mobile phones, personal computers, mainframe computers, automobiles, televisions, toys, and many others.
Types of Operating Systems
Operating systems have evolved since the earliest computer generations, adapting to the changing technological landscape. This chapter explores several essential types of operating systems commonly used today.
1. Batch Operating System:
In a batch operating system, users don’t directly interact with the computer. Instead, they prepare their jobs offline, typically using punch cards, and submit them to a computer operator. Similar tasks are grouped together to expedite processing. The operator organizes programs with similar requirements into batches.
Challenges with Batch Systems:
- Limited user interaction with jobs.
- CPU idle time due to slower mechanical I/O device speeds.
- Difficulty in providing desired priority levels.
2. Time-Sharing Operating Systems:
Time-sharing allows multiple users at various terminals to simultaneously utilize a single computer. This technique, an extension of multiprogramming, enables the processor’s time to be shared among users. Unlike multiprogrammed batch systems, where the focus is on maximizing processor use, time-sharing systems prioritize minimizing response time.
Advantages of Time-Sharing Operating Systems:
- Quick response times.
- Avoidance of software duplication.

5. Real-Time Operating System:
Real-time systems process and respond to inputs with minimal delay, controlling their environments effectively. They are utilized in scenarios requiring precise time constraints, such as scientific experiments, medical imaging, industrial control, and air traffic control.
Types of Real-Time Operating Systems:
- Hard Real-Time Systems: Ensure critical tasks are completed on time, often with limited or no secondary storage.
- Soft Real-Time Systems: Provide flexibility, with critical tasks taking priority over others but less strict timing constraints.
Real-time operating systems play critical roles in various applications, from industrial control to multimedia and scientific projects.
Top 4 Operating Systems
ChromeOS – The Secure Option
- Google’s ChromeOS stands out as an ultra-secure operating system that in many ways surpasses Windows, macOS, and Linux in terms of security.
- Security-wise, ChromeOS is based on a Linux kernel deliberately built and fine-tuned to be secure. Automated updates ensure that users are always updated with the latest security patches.
- It uses sandboxing, where a site and an app are isolated into separate processes to avoid the spread of malware. Even if one of the user’s website accesses is malicious, the damage is confined only to that sandbox.
- Its architecture, such as read-only operation and verified boot mechanisms, further protects ChromeOS against ransomware and malicious modification attempts.
- Moreover, ChromeOS comes with specific anti-phishing measures, which help prevent such attacks from breaking through.
Linux – A Historical Fortress
It has long been touted that Linux is one of the most secure operating systems. Unlike Windows, Linux denies root-level access, which improves its security by limiting the attack surface.
Linux is open-source, and a community of developers has worked hard to identify and bug-fix security issues in its codebase. The open-source code and distribution model of Linux provide variants such as Qubes OS.
Although its popularity has surged recently, Linux’s smaller user base has traditionally scared away large-scale malware development. However, recent trends have shown that the threat environment of Linux systems is growing.
macOS – Security with Apple’s Seal
MacOS boasts strong security features, dispelling the myth of invulnerability associated with Apple products. Integration on such a tight level between hardware and software allows Apple to provide users with seamless security updates and strong hardware barriers.
- Gatekeeper and XProtect are just some of MacOS’s security tools. They inspect app downloads and scan documents for malicious code, respectively.
- Although macOS isn’t, to date, unscathed by malware, its security features do provide strong protection against cyber threats. In recent years, a spurt of Mac-specific malware has been observed, though such malware is still smaller in
- Windows, the most popular operating system, was and still is the first to be scrutinized. The multi-user system was generally vulnerable and gave instant access to system-level privileges upon login.
Whereas Linux and macOS enjoy the open-source transparency by which it was developed, Windows leans upon Microsoft’s engineering prowess to discover and patch vulnerabilities.
