安全地使用網際網路
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.
Despite the measures taken to ensure that your installation of Linux is secure, there are always vulnerabilities. As an average user on the internet you can still be susceptible to:
Phishing Scams (websites and emails that try to obtain sensitive information through deception)
為確保能安全地使用網路，請將下列撇步謹記在心：
對於陌生人所傳送的電子郵件、附件或網頁連結要格外謹慎。
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 RDP 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.
