Information about the protection of your data against unauthorized access.

CD with lockWeak passwords like 123456, passwort, 111111, qwertz, abc123 or admin are still popular. If you are working with sensitive data, a good password is the first step to safe storage.

A strong password:

  • Has at least 8 characters
  • Consists of small and capital letters as well as special characters and numbers
  • Should be changed regularly (approx. every 60 to 90 days)
  • Names, birthdays, words from a dictionary, movie characters or license plates should not be contained (not even written backwards!)
  • Avoid characters that are next to each other on the keyboard
  • Do not simply attach special characters or numbers to a word


In addition, you can also contribute physically to securing your (sensitive) data. Use for example a separate lockable room or cabinet for safekeeping of your storage media. Secure your notebook against theft with a lock. Please note, however: at least two people should have access to your data (e.g. in the case of illness or absence)!

File encryption provides additional protection, especially for uploading data in a cloud environment.
