Ask The Wizard: Security of macOS vs. Microsoft Windows vs. Ubuntu

Dear Wizard of 'OZ',

I am looking to buy a new computer. In terms of security which operating system is the most secure?

Dear Noobie,

When it comes to security, all three major operating systems - Microsoft Windows, Ubuntu, and macOS - have their own strengths and weaknesses.

Microsoft Windows has long been the most widely used operating system for personal computers, which has made it a popular target for malware and other security threats. However, Microsoft has made significant investments in security over the years, and Windows 10 includes a number of security features such as Windows Defender, which provides real-time protection against malware, and BitLocker, which encrypts data stored on the hard drive.

Ubuntu, which is based on the Linux kernel, is generally considered to be more secure than Windows. Linux is known for its security, stability, and open-source nature, which means that its code is open to scrutiny by developers and security experts around the world. Ubuntu includes a range of security features, including a built-in firewall, apparmor, and full disk encryption.

macOS, the operating system used by Apple's Macintosh computers, is also considered to be highly secure. Like Ubuntu, macOS is based on a Unix-like operating system, which is known for its security and stability. macOS includes a range of built-in security features, including a firewall, data encryption, and XProtect, which provides real-time protection against known malware.

Overall, all three operating systems are capable of providing a high level of security, and the choice between them will ultimately depend on your individual needs and preferences. However, if security is your primary concern, Ubuntu and macOS are generally considered to be more secure than Windows.
