Countdown style:

#5. Keep your software up to date

#4. Use a solid backup strategy (3-2-1), backup your data regularly

#2. Follow the rules of ‘least privilege’ and practice strong authentication policies

The most efficient:

#1. VALIDATE your security controls and defenses against Ransomware. The technology exists and it’s one click away from you – www.pentera.io
