  1. Make sure you have regular offline or cloud backups of your most important and critical data.
  2. Ensure that you are always applying the latest critical updates and patches to your system OS and other key software (e.g. browsers).
  3. Install the latest versions of and apply best practice configurations of security solutions such as Trend Micro to provide mutli-layered security.
