Windows 10 : Windows has many features that provide integrity to the OS and user data files. If anything deleted a system critical file, SFP ensured that Windows would immediately replace it with a known good copy. Windows Vista introduced a version of SFP known as Windows Resource Protection, which also protected critical Windows registry settings, although what was protected and automatically replaced diminished overall.
With file and registry virtualization, most of the OS critical files and registry settings are protected by virtualization so that if an unelevated user or process tries to modify them, the modification will instead happen to an additional, virtual, copy of the file or registry.
This prevents unelevated users and malware from modifying system-critical files and registry settings as easily as they did before. Apple macOS: Introduced in El Capitan in , the security feature called System Integrity Protection SIP addresses the problem with unrestricted root access if malware or hackers gain access to the account credentials. SIP protects the contents and permissions of certain important files and directories, even from actions performed as root.
SIP protects against running unsigned kernel extensions, and it protects processes against code injections and real-time modifications to code without specific entitlements. Only properly signed apps can modify the protected system directories, and those apps must be tied to a developer ID and with entitlements signed by Apple. Windows Starting with Windows Vista, Microsoft no longer tried to invent its own encryption ciphers and algorithms.
Instead, it deployed respected cryptography e. Upon startup, the T2 chip takes over, and using its hardware-encrypted Secure Enclave to compare keys, loads the bootloader, ensures its validity, validates the firmware, and then validates the kernel and drivers that allow the Mac to run.
Windows Every version of Windows has had multiple ways to backup and restore files. It allows individual files to be restored from previously saved versions, if covered by the Previous Versions saving process. Starting in Windows 8, a backup-and-restore feature called File History is available.
While not a complete system backup, File History is often just what users need, especially when the Windows OS can be restored separately already. File History, by default, attempts to back up the most popular areas for people storing files and configuration settings, such as My Documents, Music, Documents, Videos, Desktop, Downloads, and AppData, but you can also include and exclude any files and folders you wish and then make a backup schedule.
This service aims to make the backing up process easy, in a set-it-and-forget-it kind of way. Once confirmed, the backup process begins. Time Machine keeps hourly backups for the past 24 hours, consolidates that data into daily backups for the last month, and then consolidates everything older than that into a weekly backup set.
When storage space runs low, Time Machine compensates with the deletion of the oldest weekly backup. Time Machine settings can be modified under the System Preferences. Windows Microsoft started to get very strict on what an application could do to another application or what an application could do to the operating system with Windows Vista.
It put a hard separation between the OS, services, and end-user applications. With Windows 8, Microsoft created a more protected class of applications called Metro apps. They were eventually named Modern Applications. Modern Applications, following the lead of Apple and others, could only be installed from the official Microsoft Store and only after review and approval. Modern Apps could only run if UAC was enabled. Application Guard works on Windows 10 and in conjunction with Microsoft Edge.
Microsoft Edge and the sites and applications it hosts now run in an isolated VBS-based, virtualized environment that is separate from the OS. Sessions opened in Application Guard cannot start browser extensions, save files to the local file system, or do other higher risk actions.
Rumor has it that future versions of Application Guard will be expanded to support more applications. With WDAC, very specific allows and denies are managed by a hardware-based enforcement. One of these features will have the right level of control versus operational trade-off for your sphere of influence.
Apple macOS: The best and simplest way to stay a step ahead of potential hackers is by keeping the operating system software and apps as current as possible. If the app is caught misbehaving, Apple can pull the plug on the offending app. Considering the alternatives, the Mac App Store is as safe as it can be for app downloads. The problem: Not every app is available at the Mac App Store and sometimes a download from a third-party site is unavoidable.
Apps need to be signed with a code received from Apple to run, and those apps that pass the code check run without issue. Another feature is app sandboxing. The strengths to sandboxing also happen to be its drawbacks, so not every app supports this capability.
Many built-in apps including the built-in web browser, Safari offer sandboxing protection. Another feature worth noting in macOS High Sierra: any kernel extension installed by an application needs explicit approval to run. This should cut down the probability of malware sneaking in unauthorized software without user knowledge and consent. It has one-button configuration resets to get rid of any possible malicious modifications and can be put in the Windows Defender Application Guard mode.
Every website and download is evaluated by the Windows Defender Smartscreen feature, which in Windows 10 extends across the whole Windows OS and not just the browser. Windows Microsoft is often on the cutting edge of network and wireless security technologies. Besides long supporting wireless and network standards, it often adopts them early and pushes them to customers before most customers are ready e. A long-time network defense built into Windows is the ability to put any network or wireless connection on a separately managed profile.
This allows different firewall, router, and other security settings to be enforced on a per-connection basis. Windows Windows Defender Antivirus has proven to be a top notch and un-intrusive antimalware program, especially when deployed in its default state along with Windows other antimalware features like Smartscreen and Windows Defender Exploit Guard. Windows allows any antimalware program to load itself just after the critical OS boot processes and before any other, non-essential applications load with a featured called Early Loading Antimalware ELAM.
Then in May, the popular video transcoder Handbrake was hacked, and an infected version was distributed with the OSX. Attacks are becoming more sophisticated, and so are the mechanisms in place to help deal with potential breaches. On the Mac, routable network services are disabled by default, and many modern applications and services are sandboxed. That means that apps and system services have limited access to available system resources; malicious code is prevented from interacting with other apps or the system.
Apple also has a more extreme way to fight malware. Using a silent automatic update, Apple maintains a blacklist of known malware threats on every Mac. Any file marked unsafe opens a warning notification, with the option to move said file to the trash.

What is Windows Defender Offline? But Edge notes that over the past few years, Windows has closed off elements of its platform, bringing it closer to Apple's security.
The bottom line: Macs and PCs both have flaws and vulnerabilities, albeit in slightly different ways. For example, cybersecurity company Kaspersky suggests that Windows requires more active security upkeep, while Apple has been less proactive with security updates and patches.
No matter which operating system you may be using, don't get lulled into a false sense of security. Privacy settings and proper digital hygiene should be applied across the board, and Edge notes that users have pretty granular control of these options on all platforms.
