# インターネット上で安全性を維持する

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.

Linux をセキュアにするための対策を取っていても、脆弱性を完全に取り除くことはできません。インターネットの平均的なユーザーの場合、次の被害に遭うおそれがあります。

フィッシング詐欺 (偽装して機密情報を盗もうとする web サイトやメール)

悪意のあるメール転送

悪意のある (ウイルスを持つ) アプリケーション

Unauthorized remote/local network access

オンラインでの安全を確保するため、次の点に留意してください。

知らない人から送信されてきたメール、添付ファイル、リンクなどには注意します。

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.
