Most people don't think (enough) about security when using the internet. One example: non-encrypted emails. Strictly speaking, a non-encrypted email is much more insecure than a postcard that can be read by everybody during delivery.

• Signing and encrypting emails (e.g. GnuPG)
• Secure protocols for communication via internet: HTTPS, TLS, SSH, SFTP
