Why should I bother with security
Permanent data loss (family photos, cryptocurrency, business data)
Personal discreditation (chats, GPS, camera, microphone, private photos)
Data leakage (NDA, know-how, source codes)
Damage to other subjects (passing a virus)
Password security
What is the deal with passwords?
Who knows my passwords?
No, passwords are not equal!

Update applications and devices (esp. operating system and web browsers)
Antivirus + firewall
Use common sense
Install just needed applications
Don’t let anyone touch your devices
Encrypt your devices (e.g. Bitlocker, FileVault)
Protect yourself (cont.)
Backup your data (e.g. utilize cloud storages)
Have a recovery plan
