Introduction
Operating systems are the backbone of modern computers, serving as the interface between hardware and software applications The efficiency and security of an OS directly impact the overall performance and safety of a computer system. As cyber threats become increasingly sophisticated and the need for high-performance computing grows, it is essential to understand the capabilities and limitations of different operating systems[1]. Windows, macOS, and Linux are the most commonly used operating systems today. Each of these systems has unique architectural designs and security features that cater to different user needs and preferences. This study arises from the necessity to comprehensively compare these operating systems and provide information that will help users make informed decisions.
Hypotheses
Performance: Ubuntu 20.04 LTS will exhibit superior performance under heavy workloads due to its lightweight and customizable kernel.
Security: macOS Catalina will demonstrate stronger security mechanisms due to its Unix-based architecture and stringent security protocols.
Resource Management: Windows 10 will showcase various resource management capabilities, balancing performance and user-friendliness.
Literature
The evolution of operating systems has seen a transition from simple batch processing systems to the complex, multitasking environments we use today. Key texts in this field include Andrew S. Tanenbaum's "Modern Operating Systems" and Abraham Silberschatz, Peter B. Galvin, and Greg Gagne's "OperatingSystem Concepts". These works provide foundational knowledge on OS architecture, process management, memory management, and security[2] .
Windows 10
Developed by Microsoft, Windows 10 is one of the most widely used operating systems. Its architecture is based on a hybrid kernel that combines elements of monolithic and microkernel designs. This hybrid approach allows Windows 10 to support a broad range of applications and hardware configurations, contributing to its widespread adoption. However, this complexity also introduces potential security vulnerabilities and performance inefficiencies [3].
macOS Catalina
Developed by Apple Inc., macOS Catalina is known for its robust security features due to its Unix-based architecture. macOS Catalina integrates advanced features such as System Integrity Protection (SIP) and the Gatekeeper security model, designed to prevent unauthorized access and malware execution. These features make macOS Catalina a preferred choice for security-focused users [4].
Ubuntu 20.04 LTS
Ubuntu 20.04 LTS is a popular Linux distribution known for its high level of customizability. Its kernel can be tailored to specific needs, providing excellent performance and flexibility. The open-source nature of Ubuntu encourages continuous improvement and innovation, resulting in a dynamic and robust operating system[5].
Methods and Experimental Design
To evaluate the performance and security of Windows 10, macOS Catalina, and Ubuntu 20.04 LTS, weconducted a series of experiments.
Performance Metrics
We used benchmarking tools such as Geekbench, Phoronix Test Suite, and CrystalDiskMark to evaluate CPU usage, memory management, and disk I/O performance under different workloads. These tools provide quantitative data on how each operating system handles various computational tasks and resource management .
Security Features
The effectiveness of built-in security mechanisms was analyzed through penetration testing and vulnerability assessments using tools like Metasploit and Wireshark. These tests simulated cyber attacks to evaluate how well the operating systems protect, detect, and respond to security threats .
Metasploit Usage
The Metasploit Framework was used to conduct various attack scenarios against each operating system.These scenarios tested the resilience of the operating systems against known vulnerabilities.
Windows 10: Detected 15 vulnerabilities, 60% of which were successfully exploited.
macOS Catalina: Detected 10 vulnerabilities, 40% of which were successfully exploited.
Ubuntu 20.04 LTS: Detected 12 vulnerabilities, 50% of which were successfully exploited.
Wireshark Usage
Wireshark was employed to analyze network traffic. The network traffic was monitored on each operating system to detect potential security vulnerabilities and data leaks.
Windows 10: Detected an average of 5 data leaks.
macOS Catalina: Detected 2 data leaks.
Ubuntu 20.04 LTS: Detected 3 data leaks.
