Linux通常被認(rèn)為比Windows和macOS更安全，但并非絕對(duì)免疫。其安全性優(yōu)勢(shì)源于設(shè)計(jì)、用戶習(xí)慣和使用方式。首先，Linux桌面市場(chǎng)份額小，受攻擊較少，但仍需警惕服務(wù)器配置不當(dāng)?shù)娘L(fēng)險(xiǎn)；其次，默認(rèn)的強(qiáng)權(quán)限模型限制了普通用戶的操作權(quán)限，減少了惡意軟件的危害；此外，開(kāi)源特性使漏洞能被快速發(fā)現(xiàn)和修復(fù)，但依賴社區(qū)維護(hù)質(zhì)量；最后，系統(tǒng)安全性還取決于用戶的配置與使用習(xí)慣，如更新軟件、避免隨意安裝包和合理設(shè)置SSH訪問(wèn)。因此，盡管Linux在設(shè)計(jì)上更安全，但正確使用仍至關(guān)重要。

Yes, Linux is generally considered more secure than other mainstream operating systems like Windows and macOS — but not because it’s magic or immune to threats. It comes down to design choices, user habits, and how the system is used in real life.

Fewer Targets Mean Fewer Attacks

One reason Linux feels more secure is that it has a smaller market share on desktops. Malware authors tend to target what’s most common — which means Windows gets hit the hardest, and macOS is catching up as it becomes more popular.

• Attackers focus on platforms with the most users.
• Less malware is written specifically for Linux.
• That doesn’t mean Linux can’t be attacked — just that it’s less frequently targeted.

But don’t get too comfortable — if you're running a public-facing Linux server, especially one that's misconfigured, it can absolutely be compromised.

Strong Permissions Model by Default

Linux was built from the start with multi-user environments in mind. This means it has strong permission controls baked in at the core.

• Users aren’t admins by default — you have to use sudo or switch to root.
• This makes it harder for apps or scripts to make big changes without your approval.
• Compare that to Windows, where many users run with admin rights all the time — making malware attacks easier.

A good practice:

• Don’t log in as root unless necessary.
• Use separate accounts for different tasks or users.
• Keep software updated through package managers — they’re usually reliable.

Transparency Helps Security

Because most Linux distributions are open source, code can be reviewed by anyone. If there's a vulnerability, someone in the community often finds it quickly and fixes it.

• Open-source doesn’t automatically mean secure, but it does mean more eyes on the problem.
• Bugs can be patched fast once found.
• However, poorly maintained open-source projects can still be risky.

Also, many Linux distros provide long-term support (LTS) versions, which receive security updates for years — great for servers and enterprise use.

Security Depends on How You Use It

Let’s not forget: no OS is perfectly secure. A lot of security depends on how you configure and use the system.

For example:

• Running an outdated Linux server with default passwords? Not secure.
• Installing random .deb packages from sketchy websites? Risky move.
• Leaving SSH open to the internet without a firewall or key-based login? Inviting trouble.

So while Linux gives you better tools and defaults, it’s still possible to mess things up if you're not careful.

In short, Linux tends to be more secure out of the box and by design, especially in server environments. But security isn’t just about the OS — it’s also about staying smart and proactive.基本上就這些。
