The latest iteration of Apple’s operating system, macOS Big Sur, has been touted as a significant overhaul of its predecessors. With a revamped design, improved performance, and a slew of new features, Big Sur has been making waves in the tech world. However, one crucial aspect that often takes center stage is security. After all, with cyber threats becoming increasingly sophisticated, users want to know if their operating system can keep up. In this article, we’ll delve into the security features of macOS Big Sur and explore whether it indeed provides a more secure computing experience.
A Brief History of macOS Security
Before we dive into the security features of Big Sur, it’s essential to understand the context. macOS has a reputation for being a secure operating system, but it’s not impervious to attacks. Over the years, Apple has implemented various security measures to fortify its operating system. From Gatekeeper, which controls app installation, to XProtect, which scans apps for malware, macOS has had its fair share of security features.
However, as cyber threats evolve, so must the operating system’s defenses. macOS High Sierra, released in 2017, introduced the Apple File System (APFS), which replaced the aging HFS+. APFS brought with it enhanced security features, such as encryption and access control lists (ACLs). macOS Mojave, released in 2018, further expanded on these features by introducing Dark Mode and a redesigned Mac App Store.
What’s New in macOS Big Sur?
So, what’s new in macOS Big Sur that makes it more secure? Let’s break it down:
System Extensions and the Death of Kernel Extensions
Kernel extensions, which allowed developers to interact with the macOS kernel, have been a significant security concern. Malicious actors could exploit these extensions to gain unauthorized access to system resources. Big Sur introduces System Extensions, a new framework that replaces kernel extensions. System Extensions are safer, more modular, and provide better isolation between the system and third-party code. This shift not only improves security but also makes it easier for developers to create and maintain extensions.
Secure Boot and the T2 Chip
The T2 chip, introduced in 2018, is a secure processing unit that handles encryption, secure boot, and other low-level tasks. In Big Sur, the T2 chip is now enabled by default, providing an additional layer of security. Secure Boot ensures that only authorized software can run on the system, making it difficult for malicious actors to inject malware during the boot process.
Built-in Two-Factor Authentication
Two-factor authentication (2FA) has become a staple of online security. Big Sur takes 2FA to the next level by integrating it into the operating system. When you set up a new user account, you’re prompted to enable 2FA, which adds an extra layer of protection against unauthorized access.
Enhanced Gatekeeper Protections
Gatekeeper, which debuted in macOS Mountain Lion, has been a crucial security feature. In Big Sur, Gatekeeper gets a significant upgrade. It now scans apps for malware and other malicious content in real-time, using advanced machine learning algorithms to identify potential threats. This means that even if you accidentally download a malicious app, Gatekeeper can detect and prevent it from causing harm.
Improved XProtect and Notarization
XProtect, the malware scanner built into macOS, has been revamped in Big Sur. It now uses advanced machine learning models to detect and block malware. Additionally, the notarization process, which verifies the authenticity of apps, has been streamlined and made more efficient. This ensures that only trusted apps can run on your system.
Enhanced Data Protection
Big Sur introduces a new data protection framework that allows apps to request access to sensitive data, such as contacts or photos, on a need-to-know basis. This granular control reduces the attack surface, making it harder for malicious actors to access sensitive information.
Removable Storage and Encryption
Big Sur takes a significant step forward in removable storage security. When you connect an external drive, the operating system automatically encrypts the data on that drive. This means that even if the drive is lost or stolen, the data remains protected.
Additional Security Features in macOS Big Sur
While the above features are significant, Big Sur includes several other security enhancements:
Sign in with Apple
Sign in with Apple, a feature introduced in iOS 13, allows users to sign in to apps and websites using their Apple ID. This feature is now available on macOS, providing an additional layer of security and convenience.
Password Monitoring
Big Sur introduces password monitoring, which alerts you if your passwords have been compromised in a data breach. This feature uses advanced machine learning algorithms to detect and notify you of potential security risks.
Enhanced Privacy Controls
Big Sur provides more granular privacy controls, allowing you to fine-tune your privacy settings. You can now control which apps have access to your location, microphone, and camera, among other sensitive data.
The Verdict: Is macOS Big Sur More Secure?
With the slew of security features and enhancements in macOS Big Sur, the answer is a resounding yes. Big Sur fortifies the operating system with advanced security measures that make it more difficult for malicious actors to gain unauthorized access.
While no operating system is completely secure, Big Sur takes significant steps forward in terms of security. The shift to System Extensions, the enhanced Gatekeeper protections, and the built-in two-factor authentication all contribute to a more secure computing experience.
However, security is an ongoing battle, and staying secure requires constant vigilance. It’s essential to keep your operating system and apps up to date, use strong passwords, and practice safe computing habits to minimize the risk of attack.
Conclusion
In conclusion, macOS Big Sur is indeed a more secure operating system than its predecessors. Apple’s commitment to security is evident in the numerous features and enhancements that make Big Sur a formidable fortress against cyber threats.
As the threat landscape continues to evolve, Apple will undoubtedly continue to refine and improve its security features. For now, users can rest assured that Big Sur provides a robust and secure platform for their computing needs.
