The Linux operating system
is inherently more
secure than Microsoft Windows, by virtue of its design.
One of the most popular, free open source user-friendly, Linux distributions is
Ubuntu.
⇧
Irrespective of which operating system you use (Microsoft Windows, Apple Mac OS X or one of the numerous Linux distributions), never:
- download, or open, unsolicited file attachments
- reply to spam
- purchase products advertised by spam
- click on links that take you to websites that invite you to enter credit card, bank account details, passwords, etc
- run programs from untrusted sources
Always, when using online banking, e-commerce websites, etc:
- type the URL yourself and ensure that the URL begins with https, not http
- make sure that there is a padlock displayed in the bottom right-hand corner
- if you use Firefox, select the Private Browsing option before going online: Tools → Start Private Browsing
More tips for staying safe online:
- use security software that can tackle viruses and spyware
- use a firewall
- utilise HIPS, if your firewall provides the option
- apply operating system updates as soon as they become available
- be highly suspicious of all unsolicited e-mails bearing attachments
- keep your browser up-to-date

security, then visit the security section of the Information
