使用网络时保持安全
A possible reason for why you are using Linux is the robust security that it is known for. One reason that Linux is relatively safe from malware and viruses is due to the lower number of people who use it. Viruses are targeted at popular operating systems, like Windows, that have an extremely large user base. Linux is also very secure due to its open source nature, which allows experts to modify and enhance the security features included with each distribution.
尽管已经有很多措施来保护您的 Linux 系统安全，但漏洞总会存在。作为一个普通网络用户，您仍容易遭受以下威胁：
网络钓鱼(尝试通过欺骗获取敏感信息的站点)
要远离恶意入侵，请牢记以下提示：
不要打开未知人员发送的电子邮件、附件或链接。
If a website’s offer is too good to be true, or asks for sensitive information that seems unnecessary, then think twice about what information you are submitting and the potential consequences if that information is compromised by identity thieves or other criminals.
Be careful in providing root level permissions to any application, especially ones that you have not used before or which are not well-known. Providing anyone or anything with root level permissions puts your computer at high risk to exploitation.
Make sure you are only running necessary remote-access services. Having SSH or VNC running can be useful, but also leaves your computer open to intrusion if not secured properly. Consider using a firewall to help protect your computer from intrusion.
