[5 security tips for shared and public computers][1]
=============================================
![](https://cdn.fedoramagazine.org/wp-content/uploads/2016/09/securitytips-945x400.png)
For many of us, the most important part of security is making our personal data safe. The best security will withstand any abuse, theoretically. However, in the real world, you can’t cover _all_ possible situations of abuse. Therefore, the best strategy is to use multiple techniques for increasing security. Most normal people don’t need complicated schemes and [cryptography][2] to be safe. But it’s good to make it hard for intruders to get access to your data.
It may sound silly, but the computer in a library, a classroom, or a lab — or your friend’s phone for that matter — aren’t yours. Even cloud or cloud services in general are usually just someone else’s computer. In general, treat any devices you don’t own as if they’re owned by a villain — in other words, someone who wants your data for evil purposes.
Here are some simple ways you can increase your data security against miscreants or intruders.
### Close open sessions
When you’re finished with the device, log out of services such as Facebook or other sites. This helps keep an evildoer from reopening the windows and having access to your account.
### Clean browser and other cache
Clear all your history, passwords, and cookies from the browser you used. Don’t assume this is the default behavior on logout. Depending on the platform, check caches as well. You can delete the _~/.cache_ folder if you’re on a modern Linux system.
### Empty the trash
Remove any items left behind on the desktop, if applicable, and empty the account’s Trash or Recycle Bin.
### Use service security options
Enable login notifications or approvals for your services and accounts. Some services have an option that notifies you when someone logs into your account from a new device or location. You’ll also get a notice when you login legitimately. But it’s helpful to know if someone tries to use your login unexpectedly from another computer or location.
Other services may allow you to approve any login activity via an email notice. Access is only granted if you approve via a link in the email you receive. Check your services to see if they offer either of these security options.
### Limit sensitive data
The easiest way to keep data safe on a computer you don’t own is not to process it to begin with. Try to avoid or limit work that needs sensitive information. For example, you might not want to access bank or credit card accounts, or secure systems for your workplace.
You may want to consider using a Live USB-based operating system for these purposes. Live USB limits or even completely avoids any data storage on the host computer system where you run it. You can [download a Live Fedora Workstation operating system][3] for use on a USB stick, for example.

[5 个对于共享及公共计算机的安全提示][1]
=============================================
![](https://cdn.fedoramagazine.org/wp-content/uploads/2016/09/securitytips-945x400.png)
对我们许多人来说，安全最重要的部分是使我们的个人数据安全。理论上，最好的安全性能够承受任何滥用。然而，在现实世界中，你不能覆盖_所有_可能的滥用情况。因此，最好的策略是使用多种技术来提高安全性。大多数正常人不需要复杂的方案和[加密][2]来保持安全。但是可以让入侵者访问你的数据变得很困难。
这可能听起来很蠢，但在图书馆，教室或实验室中的计算机 - 或者你的朋友的电话 - 它们不是你的。即使是云或云服务通常也只是别人的计算机。一般来说，将你不拥有的任何设备视为属于罪人所有，换句话说，他们想要你的数据用于邪恶用途。
以下是一些简单的方法，可以增加你的数据安全性来应对不法之徒或入侵者。
### 关闭打开的会话
当你用完设备后，登出如 Facebook 或其他站点服务。这可以防止作恶者重新打开窗口并访问你的账户。
### 清理浏览器和其他缓存
清理你浏览器中所有的历史、密码和 cookie。不要假设这些是登出后默认的动作。取决于平台，同时检查缓存。如果你使用的是 Linux 系统，删除  _~/.cache_ 缓存文件夹。
### 清空垃圾箱
删除桌面上遗留的任何东西，如果可以，同事清空垃圾箱。
### 使用服务安全选项
为你的服务和帐户启用登录通知或批准。某些服务有一个选项，当有人从新设备或位置登录你的帐户时通知你。当你登录时，你还会收到通知。但是，了解某人是否尝试从其他计算机或位置意外使用你的登录信息很有帮助。
一些服务可能允许你通过电子邮件通知批准任何登录活动。只有通过你收到的电子邮件中的链接进行批准，才能授予访问权限。检查你的服务，看看他们是否提供这些安全选项。
### 限制敏感信息
在不属于你的计算机上保持数据安全的最简单的方法是不要处理它。尽量避免或限制需要敏感信息的工作。例如，你可能不想在工作场所访问银行或信用卡帐户或者安全系统。
你可能需要考虑使用基于 Live USB 的操作系统来实现这些目的。Live USB 会限制甚至完全避免在运行它的主机系统上的任何数据存储。例如，你可以[下载 Live Fedora Workstation 操作系统][3]在 USB 上使用。
