Windows vs. macOS: Security, Flexibility and Vulnerabilities Comparison

When it comes to choosing between Windows and macOS, security and system design play a crucial role. Both operating systems have their strengths, but their approach to background processes, system modifications and security measures differ significantly. Let’s explore how Windows and macOS compare in these aspects.

Background Processes: Who Runs More?

One of the first differences is the number of background processes running by default. Windows has a significantly higher number of system services, telemetry processes and background tasks. Features like Windows Update, Defender and OneDrive sync contribute to this. A fresh Windows installation can easily have over 150 background processes.

On the other hand, macOS is designed with efficiency in mind. Being a Unix-based system, it runs fewer background services and manages them through launchd, which keeps processes optimized. A clean macOS installation typically runs around 80-120 processes, making it lighter in comparison.

Why Windows Needs More Background Security Monitoring?

Windows does not have a filesystem-specific security model like macOS. Unlike macOS, where system files are protected with System Integrity Protection (SIP) and a read-only system volume, Windows allows modifications to system files if the user has administrator privileges. This flexibility, while useful for enterprise and legacy software, also increases security risks.

Because of this, Windows relies on real-time security monitoring tools like Windows Defender, User Account Control (UAC) and third-party antivirus software to detect and prevent threats. In contrast, macOS reduces the need for active monitoring by making core system areas unmodifiable.

How Windows Allows System Modifications?

Windows provides multiple ways to modify system settings and files, making it highly flexible but also vulnerable. Here are the key methods through which Windows allows system modifications:

• Registry Editor (regedit): The Windows Registry is a centralized database that stores system configurations. Users and applications can modify registry keys to change system behavior, which is often exploited by malware.
• Group Policy Editor (gpedit.msc): Administrators can enforce policies that affect security settings, network configurations and user permissions. Misconfigured policies can introduce vulnerabilities.
• File System Access (NTFS Permissions): Windows allows modifications to system files with administrator privileges. Unlike macOS, which has a read-only system volume, Windows does not prevent changes at a fundamental level.
• Command Line & Scripting (cmd, PowerShell, WMI): Windows provides powerful scripting capabilities that can execute system commands, modify settings and interact with low-level components. While useful for automation, these tools can be abused by malware.
• .NET Framework & Win32 API: Windows allows applications to interact with system components via the .NET Framework and Win32 APIs. These can be leveraged to modify system behavior, access protected areas or bypass security mechanisms.
• Windows Management Instrumentation (WMI): Provides deep system access for monitoring and managing Windows components. Malware often exploits WMI to execute persistent background scripts.
• Component Object Model (COM): Allows deep system integration and inter-process communication. Attackers can abuse COM objects to execute unauthorized commands.
• Driver & Kernel-Level Access: Windows allows third-party drivers to run at the kernel level. If a malicious or unsigned driver is installed, it can compromise the entire system.
• Remote Administration Tools (PsExec, Remote Registry): Windows supports remote system modifications, making it easy for administrators to manage machines but also creating attack surfaces for unauthorized access.

These capabilities make Windows highly customizable but also more susceptible to security threats when improperly managed.

How macOS Secures Against These Vulnerabilities?

Apple takes a locked-down security approach to minimize unauthorized modifications, reducing the need for constant security monitoring. Here’s how macOS mitigates the risks Windows faces:

• System Integrity Protection (SIP): Prevents even root users from modifying critical system files unless explicitly disabled. This makes system-level attacks much harder.
• Read-Only System Volume: The macOS core OS is stored on a read-only APFS volume, ensuring that system files remain untouchable by users, apps or malware.
• Gatekeeper & Notarization: Apps must be signed and verified by Apple before execution, reducing the risk of running untrusted software.
• Strict API & Sandbox Restrictions: Unlike Windows, macOS enforces API-level restrictions. Apps run in sandboxed environments, limiting their access to system resources and preventing unauthorized modifications.
• Mobile Device Management (MDM): Organizations can enforce security policies, restrict system changes and manage devices remotely while ensuring compliance with Apple’s security model.
• System Extensions & DriverKit: Unlike Windows, where third-party drivers can modify kernel behavior, macOS has replaced kernel extensions (kexts) with DriverKit, which runs in user space, preventing deep system compromise.
• TCC (Transparency, Consent and Control): macOS requires explicit user permission for apps to access sensitive data like files, camera and microphone, reducing unauthorized access.
• Secure Boot & Signed OS Updates: macOS verifies system integrity at boot, preventing unauthorized modifications to startup files. OS updates are cryptographically signed and verified by Apple.
• Limited Remote Modification: Unlike Windows' Remote Registry, macOS restricts remote system changes, making unauthorized remote access more difficult.

By enforcing these security measures at both the OS and hardware level, macOS minimizes vulnerabilities while restricting deep system modifications.

The Trade-Off: Flexibility vs. Security

Windows offers more flexibility, making it a great choice for enterprises, gamers and developers who need deep system access. However, this flexibility comes at the cost of security, requiring constant monitoring to prevent unauthorized changes.

macOS, on the other hand, prioritizes security and stability by restricting modifications. While this makes it more resistant to malware and system corruption, it also limits customization. For users who value security over deep system tweaks, macOS is the better choice.

Conclusion

Both Windows and macOS have evolved to meet different user needs. Windows remains highly customizable but requires more security monitoring. macOS reduces the need for active monitoring by enforcing strict security policies at the core level.

Ultimately, the best choice depends on whether you prioritize flexibility or built-in security. If you need system-level modifications and enterprise control, Windows is the way to go. If you prefer a locked-down, secure environment with fewer background processes, macOS is the better option.
