# Internet ja turvassa pysyminen

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-asennuksesi turvallisuudesta huolimatta ohjelmistoissa on aina vikoja. Internet-käyttäjänä olet myös kohteena seuraaville uhkille:

Tietojenkalasteluyritykset (sivustot ja sähköpostit, jotka yrittävät hankkia arkaluonteista tietoa petoksen avulla)

Haitallisten sähköpostiviestien välittäminen

Paha-aikeiset ohjelmat (eli virukset)

Unauthorized remote/local network access

Edistä tietoturvaasi pitämällä nämä asiat mielessä:

Älä avaa sähköpostiviestejä, liitetiedostoja tai linkkejä, jotka on lähetetty tuntemattomien ihmisten toimesta.

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.
